Recommended mods for track use?

Yeah, I'm gathering that the 911 turbo isn't quite as track ready out of the box as I expected. On my old 944 turbo S I literally just swapped brake pads and tires, then went out there otherwise totally stock and whupped on everyone. Sorta sad to see that the pinnacle of the Porsche's isn't the same way.
Looks like the turbo is more like my old biturbo S4's I ran, lots of power, but you need to be gentle with the consumables and give up speed on the corner entry to capitalize on the exit.

If you haven't tracked a 911 before, the main thing that you have to learn is the counter-intuitive addition of throttle when the car is feeling a little squirrely. You need to push a little weight back to make the rear end bite and go.

I've never tracked a rear engine car before, I'm looking forward to playing around with one.
I've had awd cars in the past that acted similarly, the more gas you gave them, the better they gripped...

Thanks for sharing your setup with us. I'm not sure that it helps the OP much, since as I understand it he doesn't actually own a 996TT yet. But a lot of other folks could benefit from it. I've thought about going to Motons, but I figured it would take a lot of effort to get them set correctly.

That is a GREAT baseline I just put up, which took tons of time and info/knowledge from people who do it for a living.. SO, if you decide to, build from that spec sheet

At Limerock, I had a bone stock e46 M3 there on PS1's and my 996TT as well on stock Pirelli's, it had the euro row suspension which is a little lower and stiffer then a US spec.. I was 2 seconds faster in the M3, granted driving the rear engine car was brand new to me, and I was very comfortable with the M3...

Yea, but also take it for what it's worth.. It was my first time on track with a rear engined car/Porsche, it's a feeling you have to get use to having that weight back there, I wasn't comfortable at all.. The M3 is just so easy to drive at the limits!

I am really soaking in all the good info on this thread.
The only thing really missing in this thread is some perspective of how "bad" the 996tt is on the track. A comparison to a very light, stripped and purpose built GT3 is probably not a good comparison IMHO. Neither is a built Miata or MR2. What are some of the AWD cars with similar weight and power that out perform this car on the track while being a reliable daily driver? Cars like the GT3 will always be a purpose built track that is not really a "daily driver" by any means.
Also which car will provide a better platform for tracking, daily driving and still not have to trailer it to DEs? The M3 is pretty damn good track car(especially the E36 variety), but is the 996tt a better platform on which to build for tracking?

No, I don't think the TT is a better platform than an E36 or E46, it's easier to mod to get to certain speeds, but not as good of a "teaching" car as they would be. To me the better platform is that one that works the most WITH (not for) the driver to obtain speeds, which is why the Turbo will never be elite in that category, but still a great drivers car compared to other AWD cars (Evo is the other).

One of my buddies has a Subaru WRX Sti. Not as fast as my car by about 2 seconds on a 1:20 road course. I've not driven it, but I have ridden with him. He is also a PCA instructor. It seems to be a good driver's car. It likes to go through the corners somewhat sideways. Maybe that reflects its rally origins. Doesn't have the power of 996TT.

Doc...I think your plan is a good one. Slide in some track pads, use better fluid, add some more brake duct cooling and adj sway bars and it should be tolerable on track for at least a season with not that much investment. I sorta did things exactly back a$$ward...got a tune, exhaust, suspension, roll-bar and harness and brakes
But the car is set up pretty nicely for the track...but rotors/pads and tires do become high turnover disposables...front tires (14-18 runs), rears (26-32), front pads (25-30 runs), rears (38-40 runs), front OEM rotors (30-35 runs), rear rotors (56-60 runs).
FYI, some of these are open track runs that are 25-35 minutes long. Can't really go that much longer since I run out of gas or the tires/brakes start getting greasy/soft on me. Net-net, lots of fun on the track with the turbo but not really a track car - I affectionately call my car the flying pig (as opposed to Flying Lizard for all you race fans...)

Friend of mine was in a highly modified STi (2005 model making about 460HP) and I was in my car when it was making about 510WHP with lots of lag, and still learning (fall 2007) and he was lapping about 1:26 per lap at Summit point (*2.1 mile course) and I was lapping in the 1:20s. This was also with a pretty tame suspension alignment of -1.5 front and -2.0 rear and on MPSCs and stock rotors/calipers.
Getting the suspension balanced and good fluid/Pads is a great start.
