So how did the car do? Running back-to-back and then 40 minute breathers, the car went through a LOT of fuel this weekend. Not a single hiccup though, the car ran flawlessly.

The ZL1 brakes are thermal overkill. The stock HP1000 pads however have a long and squishy pedal feel. The front calipers only registered the lowest box of 250 deg F on my caliper temp stickers. What I think I've learned here is, the SS 1LE brakes are perfectly fine as long as the pads have a thermal insulation layer, like stock. That means the SS 1LE brakes + titanium shims + track pad of choice = perfect.

Speaking of thermal, this was a HOT weekend. Air temps about 90F, and intake temps in the 120's. The car was noticeably down on power. Another problem was the track (Grattan) was green, greasy, and dirty. Saturday morning in particular meant everyone was way off the pace. It appears the track crew blew off the surface Saturday night, because from the first session today the track was much grippier.

The anti-roll bars worked great. The balance was spot-on perfect. The car will understeer if you make it, and oversteer if you make it. Drive it clean and it's neutral. This is with the Hotchkis front in the middle holes and the BMR rear in the middle holes. If you need more dynamic wheel rate, I highly recommend this combo.

I managed to crush my personal best using the Supercar 3R's, stiffer anti-roll-bars, ZL1 brakes, and Track mode "off-off"; a 1:24.59. It's not 100% roses though. The Supercar 3R's aren't magical. They lose a bunch of steering feel and have that sort of stick-through-porridge feel that Hoosier R7's do, but don't really feel any grippier than the Supercar 3's. My datalogs do show a bit more lateral G, but not much. I think the take-away here is the Supercar 3's are better than we're giving them credit for, and the 3R's aren't the final word in any way. The 3R's do maintain the same really wide window of communication at the limit, including the tire squealing, and in those regards they're definitely not Hoosier-esque. In the end I'm not sure I recommend the 3R's, and that's before I even take a look at their wear-rate. Sure I was able to go quicker, but it took a much more aggressive but precise style to coax the time out of them, whereas the 3's are overall more enjoyable. I'll have to think about this more.

I'll post my PDR data tomorrow.
