Sorry for the slow reply. Just saw this! I did exactly what you are thinking of doing. We put RBF 600 in there and it was a HUGE difference. That said, it is still pretty easy to over heat the brakes. Mine got glazed pretty badly after a few times on the track and they lost a lot of stopping power and would heat up pretty quickly, even on the street. I'd say if your brakes are about 50% and under, go out there and have a good time and just get some seat time. If they are fairly new, it might make more sense to look at another option that would hold up better at the track rather than destroy your stock set.

@@thekrogmanman thanks for your insight, let’s see how far my tax return can get me 😂😂😂

B8s weren't out yet. I'll be putting B8s on the front soon. The B6s work great in the back though. :)

@@thekrogmanman thanks. If you could compare clearance after switching to b8 with the same springs.

I'm going to keep the B6s on the back and put B8s on the front. The ride height didn't change when I went from stock to B6s. I doubt it will change on the front.
