Suppliers of Quality Performance Parts for Race & Rally

MerlinMotorsport.co.uk

We stock close to 20,000 performance parts, components, and race wear items and sell these through our website, catalogue and track-side shop. Our focus is on providing quality parts and great service at speed. Merlins’ HQ, trackside shop, race wear showroom and technical workshop are based at Castle Combe Race Circui

t in Wiltshire. We’re a team of 10 well oiled, experienced and technically competent motor racing experts and enthusiasts (geeks if you like!). Most of us have racing backgrounds and have been with Merlin somewhere between 15 and 25 years. We love what we do and, without wanting to blow our own trumpets, we’re good at it. SMALL BUT PERFECTLY FORMED…
Although we’re small in size we invest more than most in excellent staff, latest technology and massive stocks. For our customers this means on-hand expert technical help, reliably good service and confidence that your goods will be on your doorstep in the fastest possible time. HOW WE SELECT WHAT WE SELL…
We look at new products every day but we are very picky. Second-rate parts could ruin our reputation and your weekends racing, not to mention wasting your money. Therefore we only sell parts and accessories from major respected manufacturers, whose products have become industry standard. Our latest new product lines include the indispensable Longacre range, Evans coolants and TRS harnesses. Other popular, longstanding and well respected names include Samco, Goodridge, Bell Helmets, Schroth harnesses, Alpinestars, Momo and ITG to name but a few. Through our track-side shop, catalogue and website we sell thousands of standard and specialist parts for racing from low cost nuts and bolts to racing seats, steering wheels, engine components, fuel systems, race wear, instruments and gauges and much much more. WORKSHOP SERVICE - WITH A SMILE
From our technical workshops we service SPA and Lifeline fire extinguishers. We make (often while you wait) things like one off adaptors for unusual Goodridge applications, non standard aluminium hose joiners and bend roll cage and tube to customer specs. We also make brake lines and oil lines to your specs and cut steel and aluminium sheet as required. It's worth giving us a call if you have very specific needs, we're pretty resourceful and we love a challenge! NOT JUST A PRETTY SHOP…
We are constantly looking for ways to improve our customers online shopping experience. Unlike many online shops, our website checkout shows stock availability against every item in your basket and estimated days of waiting time should any item be out of stock. You’ll also see a calculated delivery date for wherever you are in the world and cheapest and fastest courier options are highlighted to help you make fastest or cheapest choice of delivery. Furthermore you do not need to go through the lengthy process of setting up an account, our simple 1-page check-out allows you to pay by card, Paypal or send your order without payment with a request for us to contact you. Our website is fully responsive to all device screen sizes (no mucking about with constantly enlarging pages to enable you to see stuff) making it easy to use from the comfort of your desk, sofa, car or shed! HELP IS AT HAND…
Our investment in technology and brilliant staff has enabled us to develop slick order to delivery systems which work like a dream. This means that our technical experts are always available (just a phone call or email away) to help fix your problems. Give us a call any time - we know our stuff and we always love a challenge! We're open 6 days a week Monday-Friday from 9am-5.30pm and on Saturdays from 9am-4pm and we also open our shop on Bank holiday race days at the Castle Combe circuit. Call us anytime on 01249 782101. From our website you can use the ‘email us a question about this product’ button from any product page (we will see which product your question relates to and get back to you as soon as possible). For instant response during our open hours you can contact us via real time live chat. QUALITY VS CHEAPEST…
Without fail every week we hear from new customers that they’ve been kept waiting and waiting for goods ordered from elsewhere. And it seems that the toil and trouble of acquiring the cheapest often results in bad service and/or poor performance of inferior parts and huge frustration. We don't sell cheap copy imports nor do we promise 'cheapest discounted prices' because that inevitably means compromise somewhere. Sometimes we’re cheapest and sometimes we’re not. We do however always promise value for money by delivering expert advice, well-researched quality products and an uncompromised speedy service. WE WON'T WASTE YOUR TIME OR MONEY…
On receiving an order from a customer, if we’re ever out of stock (which is not often) we will let you know immediately and tell you how long your goods will take to reach you if you should still wish to place your order. Unlike others, if you’re paying by credit card, we only take your payment at the point that your goods are dispatched to you – and not before. IF IN DOUBT…
Our 30 day Money-Back Promise should reassure. We only sell quality goods so we’re confident you’ll be happy. It's sometimes hard to know exactly which Goodridge Union or Jetex Exhaust bend you’ll need until you have it in your hand. Talk to us for a bit of guidance and if you’re still unsure then buy 2 or 3 and we’ll refund you for the parts returned and unused. In all cases we offer a no-quibble money back guarantee on any item (with the exception of special one-off orders) returned within 30 days providing the item is unused and in the same condition it was sent out in. MERLIN - IN A NUTSHELL…

HUGE STOCK AVAILABILITY - so you won’t be kept waiting. FAST DELIVERY WORLDWIDE - Last year 97% of Merlin UK customers received goods in 1 or 2 working days (mostly next day) with full web tracking. Merlin have the capability to deliver stocked items to Northern Europe next day, US in 2 days and Australia/NZ within 4 days. QUICK & EASY ORDERING - super-fast online ordering via a no-fuss, no account required, all on one page check-out. Or speak to an expert over the phone or via live online chat. EXPERT TECHNICAL HELP - during open hours you can get instant response by phone, email or online real-time live chat. We have recently launched the Merlin Knowledge Base which offers additional online technical help. MONEY-BACK PROMISE - within 30 days. The Merlin Shop is open Monday to Friday 9.00-5.30pm and Race days 9.00-4.00pm

Loads of lovely Jetex in our shop and warehouse.

These are custom exhaust parts for DIY exhaust systems. Jetex offer probably the most comprehensive range of custom exhaust parts in the U.K. For rally or competition use, historic or kit car applications, and for road use. It's possible to construct a high quality performance exhaust with suitable angled pieces and silencer boxes - all listed on our website but give us a call if you need help choosing the right parts for your car.

LOOK AFTER YOUR BATTERY OVER WINTER

Racing batteries are not as tolerant to mistreatment as a normal car battery - so follow these guidelines to help your battery live longer - https://www.merlinmotorsport.co.uk/knowledge_base_articles/view/care-tips-for-your-racing-battery-307

We recommend Odyssey Extreme Batteries, excellent for motorsport, light weight and powerful. With the correct treatment they'll last for many years. Built to withstand the extremes of competition racing and rallying. Increased vibration resistance allows them to withstand the constant pounding, extreme heat and vibration which competition engines can generate. See our range of Odyssey Batteries & associated parts here - https://www.merlinmotorsport.co.uk/c3285

When charging your Odyssey battery it's important that you use a charger with the correct characteristics. We recommend the following 2 products -

The Numax 10 AMP 3 Stage Battery Charger will perform this task perfectly - https://www.merlinmotorsport.co.uk/p6845

And we also recommend the Odyssey 12 Volt Battery Charger 7 AMP, designed for use on their Extreme Racing series of batteries (up to PC1100) - https://www.merlinmotorsport.co.uk/p25905W

For those like us who will spend a lot of time in the garage or shed over Christmas - here are some excellent Garage Essential Stocking Fillers!

STAINLESS STEEL HOSE CLIPS - ours feature a stainless steel 11mm wide band with rolled edges to prevent damage to your hoses. A MUST for all tool boxes! Worth keeping extra in various sizes for emergencies. Here - https://www.merlinmotorsport.co.uk/m/norma?utm

MILLERS DELTAPLEX 2EP GREASE - an essential item, not only as a general purpose grease but for use in wheel bearings and other bearings on suspension and steering joints. Here - https://www.merlinmotorsport.co.uk/p3856

SAMCO ALUMINIUM BLANKING PLUGS - These are ideal for blanking off flexible fluid hoses. These can be used to permanently blank a hose off or used in an emergency to cap off a water hose. Also handy for use when removing the engine from your vehicle to prevent coolant spilling on to the floor. Here - https://www.merlinmotorsport.co.uk/c4067

COHLINE FUEL HOSE - in various sizes and with a plain rubber, black nylon braided or stainless steel braided outer. Always worth carrying a spare couple metres in your garage, just in case! Here - https://www.merlinmotorsport.co.uk/m/cohline?utm

HYLO-GRIP HY2143 THREAD LOCK - a medium strength, fast curing thread locker. Ideal for threaded parts which may need to be dismantled in the future. Here - https://www.merlinmotorsport.co.uk/p6807

BG RACING MECHANICS MAT - A small kneeling mat measuring 450 x 210 x 30mm, made from 30mm thick heavy duty EVA foam, both water and impact resistant. Protects your knees when working low down on your vehicle. Here - https://www.merlinmotorsport.co.uk/p21442

BATTERY CABLE CRIMP EYELETS - These little things are always worth keeping in your workshop. We stock 6, 8, 10mm eyes for both 16mm² and 25mm² cable. Keep a few spare just in case you need to alter that battery cable in a rush. Here at Merlin we can crimp eyelets onto cable to your measurements. Here - https://www.merlinmotorsport.co.uk/c129

SIKAFLEX 221 - a flexible polyurethane sealant which also has unbelievable sticking powers. Ideal for bonding panels together where a fastener cannot be used or when the panel needs to be water tight. Steven, owner of Merlin, says “I bonded the oil cooler duct on my racing car together using Sikaflex and after an unfortunate impact, the oil cooler was destroyed but the duct was still intact!” Here - https://www.merlinmotorsport.co.uk/p6080

NYLON CABLE TIES - The one thing a garage or workshop should never run out of are cable ties! A cheap, simple item that has a thousand uses on and off the car. We stock a few different lengths. Keep a handful of each in your garage at all times. Here - https://www.merlinmotorsport.co.uk/c25

A few more lovely stocking fillers -

* NMB BEARINGS -
These little things of beauty are widely regarded as being the best money can buy.
These Rod Ends are manufactured from Precision Stainless Steel with a three-piece Teflon liner with radial loads ranging from 4,860lbs right up to 34,500lbs (size dependant).
We stock NMB Rod Ends and Spherical Bearings in Imperial sizes. The rod ends are available from stock in equal and unequal sizes, both right and left handed from 1/4” up to 5/8”.
If your buying decision is based on quality then we recommend these bearings for suspension and steering joints. They’re not the cheapest but definitely value for money due to their quality, strength and finish. See all Rod Ends & Spherical Bearings here - https://www.merlinmotorsport.co.uk/c184

* LED ILLUMINATED ON/OFF TOGGLE SWITCHES -
These toggle switches with built in LED warning lights are ideal for custom dash board installations where using an additional or separate warning light is not wanted. Ideal for side lights, head lights, fog/rain lights, wipers, radiator fan or whatever you fancy!
These are rated to 25 Amp and have a nice positive On/Off “click”. Available in Green, Blue, Amber and Red. See all Ignition Switches & Buttons here https://www.merlinmotorsport.co.uk/c332

* GOLD PLUG MAGNETIC SUMP PLUGS -
These are excellent! Available in lots of different threads, they’re a cost effective way to protect your engine from small metallic particles which make their way into the oil.
Simply replace your existing sump plug with one of these at your next oil change. They’re really nice quality, manufactured from Stainless Steel with an N45SH Neodymium specification magnet. All Gold Plug sump plugs are supplied with sealing washers.
More here https://www.merlinmotorsport.co.uk/c9011

* ANODISED ALUMINIUM Y-PIECES -
These handy little adaptors are available in a few different thread combinations and in the traditional red and blue colour or stealthy black. Ideal for plumbing in multiple fuel pumps or filters - with one inlet and two outlets (though these can also be used in reverse). These are quite small, so if space is restricted they're an ideal solution.
See the adaptors here - https://www.merlinmotorsport.co.uk/c9032

* QUICK RELEASE BONNET & BOOT PINS -
Quick Release Bonnet Pins. Pins are retained in the mounting plate so cannot be lost. Sold as a pair and includes pins, catches, lock nuts and self tapping screws.
More here https://www.merlinmotorsport.co.uk/c241

* MERLIN'S LONG SLEEVED T-SHIRT TOP
A great cheap stocking filler, the Merlin Motorsport long sleeve T-Shirt top features a small Merlin logo on the front and larger logo on the back. https://www.merlinmotorsport.co.uk/p25543

* A MERLIN GIFT VOUCHER -
Merlin Vouchers are a great gift especially for those awkward to buy for people. It's not always easy choosing the right gift for someone else so vouchers make sense.
More here https://www.merlinmotorsport.co.uk/c3434

* FUEL TANK BAFFLE FOAM -
We stock a foam called SafeCrest 1V. This is manufactured to Military spec as once used in US Air Force aircraft fuel tanks - it’s a reticulated polyurethane foam.
Supplied in either single 80mm cubes or as one cubic foot (56 cubes in total). There are several advantages to using this foam in your fuel tank.
• SafeCrest 1V effectively baffles fuel to prevent surge in competition vehicles under hard braking and cornering.
• It mitigates fuel spray in the event of a fuel tank rupture due to compression, like in the event of an accident.
• Prevents explosions of ignited fuel vapours due to electrical arcing or over heating.
• Can be squashed and squeezed into difficult shapes of fuel tanks and down fuel filler necks.
• A cost effective way of making your fuel tank safer, whilst controlling fuel surge at the same time.
• Suitable for all fuel types except Methanol.
• It’s maintenance free!
Fuel tank explosion suppressant foam is now mandated by a number of recognised racing organisations including the FIA, NASCAR and SCCA
