Guys,

Just got back from Thermal last night with a ton of video, photos and sound clips to go through, edit and prepare to post but I can at least put up a few laps of the GT4 at Thermal that I have posted below.

Just to give you some insight on how good the GT4 is, after only 10 laps of sorting out the chassis/suspension/tire pressures on the GT4, it was only 2.2 seconds slower than the GT3 which we have dialed in over several test days here at Thermal.

Now to be fair to the GT3, the GT4 was on 19" Hoosiers and that shorter gearing certainly helped, vs the GT3, which was on 20" Trofeo R's.....the 2 cars that are pictured in this thread.

But to only be off by 2+ seconds on a long track lap time (2:15 vs 2:13), that is impressive and says a lot about the GT4's capability.
Both cars have our header/exhaust package as well.



More info to come with more data as well....but this is all I could put together....gotta go finish the Christmas shopping for the kids, they don't care about this right now! LOL

Yes, we will be offering the rear exhaust tips in black ceramic coating just like our GT3/RS Center Sections....

Could you notice any difference in the performance of the car vs stock?

I felt more torque than top end.....it was strong off the corners vs stock mode but we will be dyno'ing the stock setup vs the GMG setup in the next week or so....

Here is a fun pic from the day, we had a blast!

You should make it clear "under my roof" they will learn to love racecar sounds and the catless aromas

Hey Mike, we didn't test the RS that day for actual data and lap times but the GT3 is quicker than the RS as the GT3 has run the Trofeo R's and the RS only has the stock MPSC II's.

Our goal is to put the 19" Hoosiers on the RS and then it will be a killer!
