Will these work with the stock brakes?

The stock part numbers are:
996TT Stock Front Rotors
996.351.409.02
996.351.410.02

These are the 996 GT3 330mm Rotors:
996.351.409.91
996.351.410.91

 

I think I found my answer (no) here:

"To be able to use the GT2/3 Rotor, which is a different offset than the AWD Turbo Rotor Hat, you would need to replace your suspension upright (The part the strut and hub/axle and balljoints/Tie rod connect at) would have to be replaced. This is a DIY that could be done, but an alignment would be needed and these suspension uprights are not cheap."

 

Use 997 350mm rotors and spacers for the calipers for an easy upgrade!

 

They will not work...

 

True. U just need longer bolts and some 1 cm big shims.
No need for OEM rotors. I use Zimmermann 350mm for the 997 TT. Cheap and good.

 

I think the shims are 10-11mm to accommodate the added 20mm. Honestly I wouldn't consider putting the 330mm on my car with such a simple upgrade available. I would like to know where to get the shims and bolts reasonably though, $100+ seems crazy and I'd make my own before I'd pay that

 

Well u can go to a porsche dealer and ask for the 997.1 tt bolts and pay "muchos dineros" for them or go google some M12x95 10.9 1.5 bolts.
The shims you will find also for M12 bolts.

They car wont brake better, but look awesome with 18 inch wheels.

 

11mm is what you want..
