Im running RE11s on 18 inch square fit (275s) for the track and PSS on 19 OEM Rays for the street
I also run Sport the setup calipers with RBF600 and Z1 2 piece rotors
Z1 2 Piece Akebono Front Rotors
I also run Stillen (OEM fascia) brake cooling ducts.
I've tried several sets of pads:
OEM (of course)
Pros: no dust, no noise, came preinstalled
Cons: huge fade in road course after 5-10 minutes of driving.
Hawk street pads
Pros: Not too dusty, good initial grip at track when cool, only occasional squeel
Cons: noticible road course fade with 20 minute session
Hawk ceramics (I dd these still in winter)
Pros: No dust, no sequel, good cold weather performance
Cons: very noticeable road course fade at high temps (do not track these... I tried)
Hawk HPS+ (I run these on track and in summer DD. I "DD brake" carefully so as to not eat my rotors)
Pros:awesome track performance when warm. Good initial grip/no fade (in my use/setup)
Cons: TONS of dust (seriously bad), squeak at every stop, very grabby for DD they need to be warmed up a bit before you can really trust them for an aggressive stop.
