Awesome thx Jean! I want to try to track the TTS again as i have only done it once and wasnt pleased with the experience on the stock PZero N0 tires. I don't want to spend $,$$$ just to see if i like tracking it on better tires so now i can borrow the cup2's from the GT3. Who knew owning both could be so economical lol.

+1 for your frugality! The difference Cup2's make is considerable.

Greetings (hopping onto the 991 Turbo forum from the 997 GT3/GT2 forum)

I recently traded in my 2007 GT3 to pick up a 2015 TTS Cabriolet. The GT3 was predominantly used for the track only, and was almost never without a set of Hoosiers. So I t was a humongous leap of faith to jump into a TTS, not to mention a Cabriolet. Well, no buyers remorse here. First time out at the track on a set of crappy P-Zero’s, I practically equaled the max lateral G forces of the GT3 on Hoosiers. (1.3 vs. 1.4). Also managed to hit -1.3 g’s under braking. I am just in awe of the track-ability of this car.

And when the day was done, instead of loading the GT3 on a trailer, I got to drive a luxury drop top on the way home. Amazing. Looking forward to learning from others and sharing my experiences. (The only changes I’ve made from stock so far were to upgrade the brake pads and brake fluid, as well as maxing out available camber in the front. Next up is to trash to P-Zeros).




128 on the main straight matches the GT3 vmax. Lat/long g’s are about the same.

Welcome to the other side! Get some Cup2's and forget about the GT3. Also, kudos for the satellite channel 114!

Congratulations on your new 991 Turbo! It would be worth considering looking into aftermarket wheel options like HRE's R101 lightweights that save you over 30 lbs over the OEM wheels and can be ordered in wider sizes so that 325 Sport Cup 2's can be used flawlessly.

Far more importantly, you can fit 265 on 9" wheels!

Thanks for the wheel recommendation. Weight loss is definitely something I’m thinking about. Despite the awesome brakes, my braking zone is much longer in turbo than it was in the GT3. Besides the higher speeds on the straights, there’s the greater mass to manage in getting it slowed down in time for corner entry. P=mv!

Yep, and I cannot say enough about the lightweight battery swap and DSCsport V3 box, too.

Let's give this a bump, too.

I just ordered the DSCsport V3; thanks for the tip and for your review thread.
Our club takes the summer off (too hot in Texas). I’ll be anxious to try it out in September when we start the fall schedule.

Have you given thought to upgrading Intercoolers? There are considerable gains, especially when tracking a turbo!

Yeah, it's on the list! Working on suspension now with TPC racing, then will look at the engine next. My track times are not due to HP as yet., but I'm sold on the advantages of a nice exhaust/intercooler/tune advantage.

265 GT2 RS N2 spec rubber in the front on 9x20" wheels, no rubbing, knocked another second off my best time at VIR on an 88 degree day. Highly recommended!!




325 rears to match the circumference of the front tires. These are Mercedes M0 spec, but they fit very well on 11.5" x 20 wheels.

Wow! They look GREAT !!!!!!

I have ordered today Girodiscs 410/390 and Ferodo DS1.11 from Apex Performance, 265(N2)/325(M0), KW springs with height adjustment, KW camber plates, LiteBlox Porsche Battery (-20,2Kg)

As exhaust I am still debating between Kline (local provider to me) and Europipe, guess EP is still a better quality and nicer sound for my style (I dont want a LOUD car), I have a 996tt with straight pipes for that.
Kline can be converted to full cat-less system later on and giving less restriction and less weight, still my heart seems to be with EP for some reason.

Still debating for next stage of mods if going to use Turbo S Exclusive OEM wheels R20 with Hoosiers or try to fit some motorsport custom wheels on R19 with slicks or Hoosiers...

I did some laps on the local track on used Pirellis ans stock config, will report back my impovements, hoping for 2-3seconds/minute on Cup2s

I'm very happy with the look of the car, too. The stance is perfect, in my judgement.
