Wow thats TUV related stuff for German market? If so, you guys rock in security and compliance regulation, we have nothing to worry over here, still I would feel safer in Germany

 

The manufacturer could make a certificate to legalize it. But they dont.

Well anyway i will see if the 996 TT will brake well with a

53.9% to 46.1% brake ratio.

 

I'm using 991 GT3 calipers and 380mm discs F&R. Brembo floating discs with German made hats. 996 GT3 MC, I'm quite happy with them, finally the front to rear balance is something I like and with 265/325 tires the stopping power is adequate.

 

I will use 18". Just curious, do the 991 GT3 calipers fit under a 18 " wheel?

 

No, at least these in mine. Some shallower race calipers do fit inside some 18" wheels.

 

Can you fit 265/35/19 and 325/30/19 ?

I would like to order from Diego a new set of rims, considering 19" if possible this time for street or Rcompound tires and use 18" for slicks only. As there arent 18" Rcompound tires wider than 295 (besides Hoosiers) I am looking to 19" options

My car being much wider I suspect will have less clearance for the fronts to fit

 

265/30-19 has the same OD than 265/35-18, so the front clears everything as before. At rear 325/30-19 has much bigger OD than 295/30-18, so issues come from that, not really from the width. There's plenty of room inside the wheel well, just be sure that outside clears the fender arch. Mine grinded room for themselves @ the dip before Schwedenkreutz, bottom of Fuchsröhre and the dip after Tiergarten...much more vertical G there than at other tracks. Fender arches themselves are OK, but rear bumper has now new design.

Another issue would be ABS, but I have custom made front tension bolt rings like John's, so tire size difference is neutralized.

 

I thought you run 265/35-19 instead of 265/30-19 !!! Now that makes sense, I am able to fit 245/35-19 in the front and still have some small clearance, I guess can do 255/35-19 but not more than that.

Would you think 305/30-19 would still provide sufficient grip, as seems to give less pain to ABS or fitting in.

I can easily run the 325/660-18 Pirelli's with a lot of room so guess even the 325s wont be a problem at all for me, but those custom front tesnion bolt rings are above my understanding to be honest.

So I can try 255/35-19 paired with 305/30-19 and shouldnt worry for ABS, just only to address the rear grip if enough, but imo no need to worry about it

 

Guys I have moved on to a 991 TTS, my focus should be from now on related to the 991, thanks for all the help provided and I will try to keep an eye here from time to time. I will post my car for sale in the classifieds, take care!

Few pics of last event on HungaroRing and the 991TTS

 

991 TTS is a great and fast car but its way too perfect to have fun with it on the race track. 996 TT is oldschool racing...


But hey, have fun with the 991 TTS !

 

I am older and having 2 kids now, I do agree the 991 is so good in a kind of boring way

 

Congrats on the 991tt, I picked up a 997.2tt myself. Your 996tt is a keeper though- would be slick if you could find a way to keep both!

 

Congrats on the new purchase!

Perhaps I have missed it, what front fender vents are those you are running?

 

No problem, they are DP MotorSport, Germany

 

Fadi is that the cup wing ure using?
