    AP racing front brake kit for 2020 GT500

    @Serpent Stang is the guy to talk to. He has the fastest gt500 in US. He runs AP RACING brakes. I think he can take care of you. Especially if you are planning to reduce weight. This a huge upgrade for the car. Less consumable costs. Smaller wheels for less weight. Win win.

    Why new front splitters seem to have an upturned lip? (AJ Hartman please help)

    It is all depending where you want the downforce. the upturned splitter allows for more air To be squeeze under the car. The More air squeezed. The faster the air has to accelerate to preserve the momentum. The faster it goes to do that, the more suction you get. Same concept with a splitter...

    NASA TT, Reduce power to stay in TT# and run Hoosier?

    At least 2 or 3 seconds faster. A7 is the best TT tire. If you want a compromise (but not contingency) you should consider some A052 yoko. It is -1 (vs 1.6 of RR) A052 are similar in Lat G with hoosier slighty worst in braking G But they ain't cheap and the real "hero lap " happens in the...

    Italia Speed Racing thread

    The fast release splitter.kit is been tested also to fast release a diffuser. In this case the AJ Hartman one. It works awesome. Bolt on in the front and i made 3 holes in the back using rivnuts for M8 BOLTS. So solid. I might also put 2 rods to extra secure it, still debating.
