TPC Racing

This 997.1 Turbo making 600+hp got a suspension makeover at TPC Racing to vastly improve road compliance, agility and balance on twisty, and track performance. The car owner is an experienced GT3 Cup driver, he is using the 997 Turbo mostly for street, from leisure weekday work commutes to fun weekend canyon runs, with occasional open track days in a comfortable, well-balanced and sharp-handling car. The following combination was used for this project.

• DSC Sport suspension controller - Dynamically control individual dampers to g-force and driver's inputs in real time.
• DSC Sport Tractive RT Coilovers - Electronic spool valve dampers to react to DSC controller's commands in milliseconds, monoball front and rear top mounts for precise vertical motion.
• TPC Racing Front Wide Track Kit - Widen front track width by 26mm(within the car's bodywork) to maximize front grip using OEM GT2/GT3 spec ball joints, and lengthen wheelbase.
• TPC Racing Metal Rear Subframe Bushings - Eliminate rear subframe rubber deflection that causes the entire rear suspension to shift during peak lateral loading.
• TPC Racing Rear Caster Bushings - Eliminate rear caster/thrust deflection, and length wheelbase.
• TPC Racing Adjustable Rear Toe Links - Eliminate lateral load deflection that causes unwanted rear toe change, and significantly improves bumpsteer curve.
• TPC Racing Rear Upper Links - Eliminate rear camber deflection and rubber stiction.
• TPC Racing Front & Rear Sway Bars - 28.7mm OD 5-hole adjustment front bar and 22.5mm OD 4-hole adjustable rear bar to improve grip balance and to minimize body roll.
• TPC Racing in-house installation and chassis setup

Various steps of this project shown below.

Rear subframe removed.


Extracting rear subframe rubber bushings.


Replacing rear subframe rubber bushings with metal (a'la GT3, GT2, RS, Cup, R, RSR).




Extracting rear lower arm caster/thrust bushing.


Replacing with lower control arm bushings with TPC adjustable metal bushings (a'la GT3, GT2, RS, Cup, R, RSR).


Installing TPC rear toe links, TPC rear upper arms, and DSC coilovers.




Front DSC coilovers prepared for install.




Installing TPC front wide track kit (consisting for longer motorsports front lower control arms, longer front tie rods, and front axle spacers).






Installation and chassis setup completed.

curious to the ballpark of cost for a setup like this?
in fact... if someone wanted to move from a standard 997.2 Turbo to something like this in stages.. maybe a breakdown of that journey would be helpful. I have a DSC module and really think that it is something on the order of the invention of "sliced bread" (and being quite vocal about it here on the forum). Is there anything even between a $1390 controller and a race car setup?

Yes the total is probably eye watering and worth it but not for mere mortals

absolutely gorgeous...and absolutely overkill for non-track daily.

Thank you for using the DSC controller! Very glad you are enjoying it.

Commonly sway bars or coilovers are the next stage for high performance mod after the DSC controller for a 997 RWD car, however on a 997 AWD car the front sway bar mounts are built-in to the OEM front struts, so in order to fit GT-type front bar and have it fully effective, coilovers that have the proper front sway bar mounts built-in are needed. The coilovers are the single most costly item in this build- the coilovers + labor is almost half the cost of the build. For creating a hierarchy for high performance mod stages for the 997TT, coilovers first to get the big ticket item out of the way. Then either sway bars at the same time or later. Followed by monoball arms and metal bushings for one end of the car at a time. For those who actually drive their cars replacing the 10-15 y/o rubber bushing parts bring newness back in the handling of the car, especially with parts motorsports type parts that increases track width, wheelbase, and improves geometry like the GT/RS-variants.

Since you already have the DSC controller, to do everything else above is around 22K. It is def not cheap but if one had a car with worn suspension to replace all those parts with new OEM parts the cost would be halfway there.

Thanks! The owner does track it occasional. For him its about having a versatile do-it-all car...a custom built AWD GT2RS that rides nice.

Looks like an amazing drive! I also have Tractive suspension and love the suspension.
