Hi everyone,

Just a bit of an update from us! From the 1st of February CS will no longer be operating as we have. Both of us have decided that this is the best move going forward. Luke will be taking the unit on and running under a different name, doing purely mechanical work under LM autos.

This is not a decision that has been easy to make, but it’s the right one at this moment in time. To everyone who has supported us, helped us, used us. Thank you, from the bottom of our hearts. We have worked on, tuned and maintained some insane cars over the past year and a half. We really do appreciated everyone single person who has trusted us to work on their pride and joys ❤️

On a brighter note, we will be offering huge discounts on tuning until we close at the end of the month. So if you want to get in before then please drop us a message! Anyone who’s booked in before the end of Feb your booking still stands.

CS, it’s been a pleasure. Time to move onto bigger and better things.

Thanks and lots of love
Ben & Luke

Bagged mk5 r32 in for prop shaft replacement!

One of the worst failures we’ve seen, we managed to source a prop from a breakers and get it all fitted with a new front coupling same day for the customer. Back on the road and driving how it should 🫡

Ian’s stage 3 golf r, what an experience this has been. From faulty high pressure fuel pumps to faulty actuators we seen it all. It was an absolute fight to get this car running right, but we got there in the end. Spec as follows

-RTMG550 turbo
-Airtec intercooler
-DO88 muffler delete and charge pipe
-R600 intake
-NGK racing plugs
-Turbo technics elbow
-Autotech high pressure fuel pump
-Ecotune low pressure fuel pump
-4 bar map sensor
-Custom CS stage 3 ECU & TCU

A lot of revisions to get this dialed, we finished on a strong 508bhp/538nm. One very fast MQB. Good fun tuning this one!

Another tomei system fitted!

US spec decat downpipe mated to a tomei titanium cat back. Hands down the best sounding b58 we’ve ever heard. We have worked with a good few of these systems now and they never fail to amaze us 🫡

Andrews 335d, this is a long one…

This car initially came to us for exhaust manifold gaskets, not the smallest job itself but what we discovered turned it into so much more. Upon removal of the small turbo we discovered the first manifold stud snapped in the head ( we think by a previous garage but can’t be sure ), and we knew this was going to be a tough one! This was causing a huge blow of exhaust gases and it was making a horrible screeching noise under load .

We tried our best to extract the snapped stud, but we had no luck at all. It was too deep with no thread left sticking out we had no option but to replace the whole head itself. Andrew supplied a new skimmed head with new valves and all relevant gaskets, from there we started stripping.

Many 4am finishes later, and the car is running absolutely perfect again. This was extremely difficult and took a lot of head scratching and patience to get done. From making tools to remove seized stuck injectors, to re timing the engine, fitting cams in the new head, re fitting turbos. It was a long journey. To hear the first start up was a huge relief.

Thank you for trusting us Andrew! Swipe to see some pictures of the work/strip down. And if anyone else needs an M57 cylinder head replaced, please give us a good 6 months to recover from this one first 🤣
