I just ordered some Yokohamas A048, not sure how well they work, but people who use them as their track tires love them.I wish i could be more help, but I have only tried the factory Pilot sports and they worked well for me....But hey i will never drive the car like it can be driven!

The 996s already have a strut tower brace from the factory, you just can't see it behind all the plastic panels. The same part is used in the 996 cup cars.
FWIW I ran 17" al last year at the track, there is a small but significant difference in the price of R tires, plus the wheels can be found dirt cheap. That said I'm about to pull the trigger on some new 18" forged track wheels (BBS or CCW).

SPR,
I run 245/35/18 in front and 285/30/18 in back. It seems to be best for my car.
Mitch,
As I recall it's a combination of the strut towers being integrated with the fire wall (both front and back) and the angled brace that you see run from the strut tower to the firewall. In theory this eliminates the need for a strut brace. It's pretty much the same in stock cars and cup cars. A strut brace won't hurt and a few guys at the track have them but they certainly don't have the same impact they did on previous cars.
Bow,
Good luck with the Dunlaps. I'm sure they will be just fine.

Just a quick note on the oil starvation kit. Having just blown my motor coming through the esses at Watkins Glen (and it was guessed that it may have been a starvation issue) I requested my mechanic sought the Porsche Racing upgrade to install in the new motor. He was informed by Porsche that the kit was no longer available and that it would not be produced again. Further enquiries through a different source confiirmed this but Porsche claimed that with the new crate motor (3.4 litre) was modified to overcome the starvation issues associated with my original motor. I have no idea what that means. As some insurance I am having the Brey Krause sump extender kit installed (I am still not sure why it will help but am praying that it is better than nothing).
As to the statement that oil starvation is only an issue with slicks, I am not convinced that that is true. In my club (NER) we have had 3 blown 3.4 litre 996s (of a sample set of maybe 6 total) all running on "R" compounds and all most likely as a result of oil starvation. Not exactly absolute proof but enough for me to be concerned.

Someone else's post on a different site..................
The later 3.4 liter cars are better than the early ones as they changed the internal baffles. The 3.6 liter cars got additional oil pump capacity and as well the baffles. The 3.6 Powerkit upgrade took this even a little further with a second oil pickup point and a new baffle system. But, Porsche still recommends that if you use racing tires you should by the Porsche MotorSports Kit and install it. (Some engine disassembly is required).
This may help...

Would really appreciate more information on part numbers and process for ordering from Germany. I am very keen to insure against future failure -- if nothing else the last blown motor cost me 5 track days.

toyo ra1 is "r" compound, i an not sure TS-1 is "r" compound.
dunlop SSR really isn't very grippy for r compound.
mpsc is very progressive and sticky and last much longer than hoosiers and you can drive to/from track.
if you aren't racing, try RA1's. cheaper and last longer.
