Who makes the GT4 Clubsport exhaust system? How different is it from the Cargraphics Full Race Exhaust System (which they claim as cup version)?
Also if the GT4 had the IPD plenum, larger throttle bodies, full Cargraphics race exhaust system, how different would the Dyno results be from the GT4 Clubsport?

Congrats on the cars.

We haven't had enough thorough time with the Clubsport to know for sure what modifications have been done to the exhaust but from the exterior it appears as though it is using the standard Cayman GT4 OEM exhaust. Here is an OEM unit behind our GT4.

I plan on using my car for competing in time trial/time attack which my current track car is an E92 M3. I want to base my modifications off of the Clubsport so I can have a relative baseline for cars that see a lot of track time.

In case people missed the detailed dive into the differences, here's a link:
https://rennlist.com/forums/gt4/9050...tics-west.html
All I can see w/r to engine is that they put more oil in it, solid mounts, and that it might have a different exhaust manifold with 100cell cats that better survive track abuse. 93 Octane?
Suspension is very different. GT3 uprights with slightly different geometry, sphericals, links, KW shocks, springs, sways. 3.5/3.1 camber F/R, toe in F/R
Brakes, completely different - out of a cup car. PFC hardware on the axles, and on and on. Mostly seems like the motivation here was that it's compatible with the Cup uprights and 18" wheels, and motorsport tuning
It seems small in comparison to GT3/Cup differences which are vast (starting with the fact they don't even share a body or drivetrain).

Unless my eyes are deceiving me it looks like the GT4 CS has substantially thicker Rear Drop Links as well ?

We have had a few more GT4 CS's through our race facilities in the past months. Three were lined up last week so it made for a good opportunity to take a couple pictures.

A point worth noting, we recently installed a passenger seat into one of the ClubSport GT4's. To facilitate the addition of an extra seat we utilized our GMG Seat Base (click for details).

This weekend we will be out at Thermal to test out some spring rate changes on one of our Clubsports. The GT4 Clubbport is proving to be ideal gentleman race car.

Here is an interesting contrast between one of the Clubsports and our GT3R.
