I've been doing HPDE, Instructing and Time Trials for almost 20 years. I was at Barber Motorsports Park last weekend. Brakes - never boiled the fluid They worked well (I need to check to see if I need new pads before the next event. Before this event I changed to the RS rims and better tires (500 treadware) Played a little with pressures, the tires worked better starting at 30psi When I made a couple laps under 2 min I was happy and done for the weekend (as its set up a bonsai lap would be in the 1:40 range) which would have been a good time trial time. Since I was only instructing that 2 min time is my goal, keeps the tires from squealing at every turn but is quick enough to pass more folks than having folks pass me I love this car - need to see if someone can remove the speed limiter and then it will be my non-race track car. I have a Corvette for my race car - need to get an engine in it. Maybe the weather gods will shine on me and I can get it ready for May. |

I suspect that removing the speed limiter might be cause for stepping up a bit with the pads such as from XP8's to XP10's.
But without forced induction, or a pretty high entry speed to the longer straights, or straights effectively a bit longer than half a mile I'm wondering how much past about 120 you're actually going to see. Your 2012 LS in stock tune runs about the same power as I have in my '08 GT, and I can touch just past 120 at NJMP/Lightning and get slowed enough for T1 to not squeal the tires, and that's with about 2600' to play with coming out of T9. That's a close enough match to what an acceleration sim predicts I need for distance to have some confidence in. Your LS' brakes are fractionally bigger than mine (but have to deal with a couple hundred lbs or so more weight), and I was feeling some fade with XP8's toward the end of a 25 minute session in 50° weather with two hard braking zones spaced about half a lap apart.

VIR, Road Atlanta, even CMP and Roebling - Speed limiter :( VIR Back straight was the first time I saw that silly little message just as I was passing the south paddock, that's a long straight. I was sure I was gonna hit 140 and have to brake real early for the turn at the end. Yea, when I get the speed limiter removed I'll be calling the good folks at Carbotech for a set of front XP10. I run xp12/10 right now on my Corvette - I'll probably move to XP16 or 24/XP12 later this year (I think I got the numbers right - don't quote me on that) I'm a Carbotech guy - especially after the guys in the C5 corvettes were cracking rotors every day using the Hawk DTC compounds |
