When FORM FOLLOWS FUNCTION

Chassis overview:

991 GT3 getting the new AA Arm kit. This kit utilizes all 992 GT3RS front suspension integrated with their billet subframe. We coupled the front suspension with 991.2 Cup rear sub-frames/ uprights retaining the OEM parking brake with Motorsport hubs to ditch the OEM center lock nuts, we then of course used brake kit for additional braking power and consistency all controlled with custom valved PROactive dampers.

Body: We molded the 991 Cup flares to the bumper/ fenders to eliminate seams and double sided tape for that perfect fit with a .2 carbon RS hood👌🏻.
For the rear we used all Motorsport parts, converted the console to an OEM latch for a clean pin-less deck-lid, a fully vented lower valance and
3RS rockers.

Engine: As of now the car has a stock engine with a few of our upgrades. First is our full straight exhaust system and reinforced titanium center section with our 4” billet tips. Induction, we converted the center plenum with a .2RS using both resonance flaps activated and tuned with engine and PDK software with live map switching breathing through a 911R air box retrofitted to the Cup deck-lid.

Stay tuned on this banger for more pictures, videos and info.

Being the most precise form of alignment, getting a corner balance alignment can be one of the best ways to get your car dialed in for track/performance use, or to solve “steering pull” issues. Adjusting each corner to ensure even weight distribution and making sure each tire carries its proper share of load. This ensures the car feels equal under load when turning left/right, giving you more confidence when attacking those corners. Want to get your alignment dialed? Contact us to schedule a corner balance alignment!

As these Mezger engines continue to age, their notorious coolant pipe failures become more and more common. The adhesive that the pipes are glued with weakens over time and heat cycles, thus causing coolant leakage. Our solution? Welded billet pipes.

With the example of this 997 Turbo that came in with coolant leakage, we pulled the engine and gearbox to get undressed and deep cleaned, welded in the billet pipes, replaced old parts and seals, and pinned the cams.

If you’ve got a Mezger, take the first step in ensuring worry free driving by reaching out to us for your coolant pipe service!
