OMG I hardly ever have time to read those magazines, thanks for letting me know.
I was so slow my first time out on Lightning, I don't think I even needed brakes. My third session, I finally got up to speed.
About the brakes, I just told Chris, so I'll copy/paste: I used DTC-70 pads in the Stoptech calipers and DTC-60 in the 135i rear calipers. Braking was so easy and so consistent, no drama at all. I do see what people mean about DTC-70 being a little hard to modulate, but I think that's getting really picky.
Anthony had the same setup on his wide-body 135i, and I also took a ride in a C6 Z06 that had ST-60s with PFC pads. Both of those guys said they love the Stoptechs too. So I'm pretty sure I'm done worrying about brakes.
But ... have I ever told you how bad I want a Z06 dedicated track car? This one had Recaros, Hoosiers, everything. And that engine.
