Gorgeous day at the track coming into turn 1 at HPR. Partly cloudy, 70 degrees, and a light turnout....

That looks like fun right there!

 

Strong work on the driving and the photos. It looks like you guys had a blast.

 

Looking good !! Exhaust tips looking white inside, either running good fuel or the car real hard!

 

100 octane, pedal to the metal. The track is not allowed to sell regular fuel, only race fuel. High octane is safer for these cars anyway especially under hot +5200' conditions..

 

Wow, that second-to-last picture looks amazing. What size wheels and tires are you running?

 

CCW 18x9 and 18x12. These are one of the few 18" wheels that will clear 380mm brakes. Tires are NT01 235/40 and 315/30.

 

Looks like you had a great time and thank you for sharing the photos. Great looking car by the way.

 

Looks like fun. Thanks for sharing!

 

The wheel and tire set up looks awesome.

Can you share offsets?

Any reason you didn't do a 245 up front?

 

My offset is ET49 front and ET 44 rear. I do run 7mm of shims per side on each LCA on the front which effectively widens the track and makes the front ET42.

I didn't run a 245/40 as I didnt want to run the taller front than rear tire and had the car set up optimized for a 235/315 combo. I am currently working with and getting some coaching from a very accomplished Cup racer and will be changing to the 245/40 and 305/35 NT01 set up running a slightly taller rear with a higher load rating, as per his recommendation. This is basically a 997 GT3 set up. I'm curious to see the difference. My street set up is a 235/35/19 and 305/30/19 and I really like the way the car performs with the taller rear tire compared to the front.

 

pwdrhound -- have you tried the 305/35 rears yet? I'm pre-emptively shopping for a new set of nittos and think I'm going to make the switch.
The extra gearing alone seems worth it as long as they aren't too tall to fit in the back.

With a stock geared 996TT (no PSM & RWD) or 996GT2 there are some pretty significant gains!

 

I will be switching to the 305/35/18 set up next month as I still have one more set of 315/30/18s to burn through. I agree the gearing change is a bonus. My current gearing actually works pretty well at my track but the biggest reason my guy wants me to change to the 305/35 is the fact that this tire has a higher loading, will be a bit more progressive, and will offer a greater contact patch over the 315/30. There is a reason Porsche went to the taller rear set up on the 997gt3s and has been running it like that on the cups.

The new Nitto 305/35/18 NT01 is 26.4" tall and should fit based on the fact that a 305/30/19 (26.3") fits on my car even though its tight. If you still have rubber in your rear suspension you may rub a little under track conditions where the rear suspension will move around a bit under load as the rubber bushings compress. I have full monoball in the rear so that's not an issue but if you don't then it's something to keep an eye on as the clearance is tight near the IC hose.

 

Nice. Me too, when this current set gives up the ghost.

I still have a stock rear setup, except for locking rear toe links.

You're running GT2 rear liners, right? Wonder if that gives us any extra clearance where this will need it.

 

Yes. However, the rear GT2 liners and TT liners are now the same item listed by Porsche under 2 different part numbers. The difference is that in the GT2 application we get a little more clearance (maybe 1/2" or so) because the attachment brackets on the GT2 are different where the liner is attached about half way up on the side instead of the long bracket by the intercooler hose as in the TT.

If you are tracking your car I would highly highly recommend installing solid adjustable caster pucks and monoballs in the rear LCAs. These will lock down the rear end and really settle the car down under load because any flex in the rear will be eliminated. Result: no toe changes under hard braking or acceleration. There is zero downside to these, no additional noise or vibration. It's a pretty easy diy....remove the LCAs, press out factory rubber bushings, and press in the solid ones. Any machine shop can do it for $30 or so...
