I have another question about upgrading my brakes. Has anyone done a brake air duct upgrade to their 997 TT. If so, what specifically did you do ( front/rear and make/model ) and was it a worthwhile investment. I track my car about 90%+ of the time and have Girodisc slotted discs, Padgid Yellow RS29 and Motol 600, OEM calipers. Doing a Brembo type upgrade is not in the picture.

 

Search on the forum, I installed the gt3 i believe rs on the front and used the old fronts and cut them up and put them for the back, after that and castrol syn fluid no more heating

 

i install FVD 575 531 00 for rear air duct work fine

 

you need ducts from cup car....I have it from Dan.
