Hi All,

Taking my 993 Turbo to NJMP/Thunderbolt this Thursday/Friday for its first track outing. I am a blue driver, 26-30 track days, all on a 997S.... Anything I need to look out for with the 993TT?

Specifically in terms of handling, throttle, etc? Thinking it is going to be fast in the straights, but brake hard into the corners, and tricky on the apex with the AWD.

Also - seems that it will need 3+ minutes of cooldown time in the paddock?

Thanks, Ross

P.S. I am running Michelin PS2 N3, Aggressive/Street alignment, bilstein HD stock springs

I think you'll find that the AWD will be your friend for early on-throttle exits. You should have a blast with that 993TT. Be sure to take a really slow cool down lap before letting it idle for a couple of minutes in the paddock. Don't use the handbrake when stopped.

the turbo is heavier and faster, make sure you're brakes are ready for the beating.

Pads, fluid and a proper bleed...

If it is the first time on the track for this car, then I'd dial it back a few tenths the first session or two to cover any bit under stress on the car (stuff breaking under DE loads) that rears up. After first session, go over the car with a fine eye to make sure all is still good. Easy on the shifts. Keep an eye on the oil level, as this many high RPM runs may use up more oil then you are use to with street driving. Lots of cool down time for the turbos. To help with cool down, a cruise from the track to the entrance and back will give the turbos, the oil, and the breaks a chance to cool down more then just idling in the pits.

If Craig Mahon is running that day, seek him out, as he is a 993TT owner and a very good instructor in NNJR PCA club.

Have a blast. you will be suprised how well these cars behave with the awd. remember you do not have psm. as long as you are not running stock suspension you will be very impressed. post some pics if you have a chance!

Thanks for all the advice... my biggest concern is the lack of PSM - so I am doing it on a track where i have 8-10 days.

Also - the braking... i am not a heavy braker in my 997... but the TT is MUCH faster, so I expect to be using the brakes more - hopefully they are up to the task...

Most street suspension set ups will have a pretty thick layer of understeer to control. Older 911s take more coaxing to get the nose hooked up. Coming from a 997, you may be surprised at how much push you have until you get yout tire pressures and suspension settings to a more balanced place. It's pretty hard to get power on oversteer on a steady throttle as the AWD and rear grip are tremendous.
That being said, the mantra "don't lift" should be constantly repeated and braking in a straight line isn't a bad idea either

I was at thunderbolt on friday with my TT. ( I drove lightning Fri Sat Sun last weekend for the 24 Hours of LeMons - finished 4th - I had the fastest time of my team at 1:24.5 in a BMW e30 325e and the 4th fastest lap of the whole event) I am able to do 1:12s in the TT(of course mine has no more AWD) 12conds seems like eons on 1.9 mile track.

I always replaced my brake pads when they got to 50% thickness when I was tracking, and flushed the fluid before every event. Never had a problem.

Only issue with racing the 993tt I've had is with brakes. I run SRF, yellow RS29's in the front and black's in the back. Like most others I bleed the brakes every day at the track. Don't be fearful of the brakes though, they are very good, they just need a little tlc. For the slow corners your biggest issue will be understeer. It's fixable with the right suspension and sway bar setup. A very quick lift and back on power immediately will get the front to turn in if you are having trouble with it. High speed sweepers are great fun, the rear end will stay incredibly planted and will leave a big smile on your face!

I track mine all the time.

As mentioned above, you have no esp, you have to handle the car with the throttle, steering and brakes. You cannot just floor it out of the corners like in the 997 with the esp on.

I am amazed that given the beating the car gets nothing has broken on mine, even at 15 years old, it is a quality car built for this sort of thing.

It is hard on the brakes but they are good. Just make sure to check them. Tire pressure is also worth checking. Of course checking the oil is mandatory.

I run Super Blue brake fluid, which helps. I am on stock suspension, which is as mentioned not ideal but new Koni Sport shocks have arrived!

Have fun!

Thanks for all the advice. Was a good two days with the 993TT. It wont replace my 997S as a track car, but it was a lot of fun. Definitely need to be more gentle with the throttle, and coming out of turns put the throttle down to add grip to rear. I took an instructor for the event, he was a 993 driver and very helpful.

I will say, it is quite exhilarating coming into the straight at Thunderbolt full throttle, car is damn fast... and the brakes (dare I say it) seem to be better than the 997.

No issues occurred, i added 3/4 quart of oil but that was over ~3k of miles and two track days. Also my brake wear sensor kept coming on, despite new brakes... but i think one of the wires is corroded.

Thanks for everyones help! Ross
