Yes, it will fit 19" wheels and this is why we offer 380mm rotor kit instead of 390mm kit.

Have confirmed personally but was told all other parts are the same. Anyone have access to PET?

991 PET is publically available ... haven't seen a .2 version which you would need for p/n# comparison.

These rotor kits can instantly up-size your rotors to GT3 w/only fraction of a BBK costs.

We have both C-L and 5 lugs. Fitment and performance improvement are guaranteed.

Call or PM us for any questions.

Dang it....wish I knew about these before I bought my GiroDisc 350mm front and rear...the Racing brake rotors would have cost me around $600 more but the replacement rings are $100 less than GiroDisc.

i think 380mm rotors and retro fitting some GT2 996/997 Brake ducts on for better cooling would solve my Brake wear and heat issues and calipers turning dark red at Sebring.

A popular and economical way to improve the brake performance and look while retain the use of OE calipers.

A BBK for CS/GTS to upgrade from stock's 340/330mm to GT3's 380/380mm.

This kit will retain your stock calipers (front and rear) with a spacer so you can have a bolt on installation for those big rotors w/o having to spend extra money in buying GT3 caliper.

Since CS/GTS are not intended for tracking, so we will design the rotor 2mm thinner than GT3, so you will have the look and benefit of bigger rotos w/o the weight penalty:

380x32* front (vs. GT3 380x34)
380x28 rear (vs. GT3 380x30) - CS/GTS rear calipers limit rotor to 28mm

Our front 380x32 two piece rotors will be 22.7 lbs, still lighter than stock's 340x34 (@24.5 lbs) by about 2 lb

A better brake system by design and iron metallurgy.
RacingBrakes.com products are amazing!
