It's cold. It's snowing. Roads have way too much salt on them. And the 2012 season is too far away. Good time to start prepping for racing.
Last season I spent most of it setting up the suspension and brakes. Burned though the OEM Pzero tires (255/40R19) and ran end of the season on Conti DW.
Tread comparisons:
Both the Pzero and DW were great tires with very good street manners. Pzero had traction until the end of their tread life (worn to overlay). Given, the wet traction dropped off after 75% of life. I tend to worry less about mileage for my performance tires. The Pzero set lasted about 17k. Ran handful of autocross events and one pseudo autocross / track event (non-SCCA AX using road course) on the Conti DW tires. Worked very well for not being completely dedicated for that use; however, for national level events - I'll need more tire.
For SCCA National events, enter Goodyear Supercar G:2 in 265/40R19. Which happens to be the OEM fitment on the SVT Mustang. The G2 was developed for the C6 Z06 Corvette originally. More-or-less, its a race-like compound with a scant 8/32nds of tread depth. SCCA STX class limits me to 265 section width and 9in wide wheel and 7/32nds starting tread. This tire fits the bill.

Been a while since I updated this thread.
Ran Grattan in TTC with the Mustang at full weight - 3640 when I hit the scales. I have enough room in the modification points system to take out 140 lbs from the car.
TTD+14 / 3600 base weight
+4 for 20mm wider tires (245mm base class to 265mm as run)
+2 for axle back exhaust
+3 for non-OEM struts
+2 for springs
+2 for sway bars (GT500 front and Whiteline adjustable rear)
+2 for non-OEM panhard bar
+29 overall have to +39 before I go to B class. That has enough room for +9 in weight reduction -125 lbs.
P/W for TTC is 12:1
3600/305 = 11.80
+0.4 for tire modifier
+0.4 for >= 3600 lbs
12.6:1 when at 3600.
3480/305 = 11.40
+0.4 for tire modifier
+0.2 for >= 3450 lbs
12.01:1 @ 3480...perfect. And pretty much just passenger seat and rear seats will get me ~100 lbs. Easy.
Areas of opportunity:
-Weight reduction
-Brakes
Ducts are a must. Melted the pads off in my first session. Yeah, on fire. Grabbed a set of Hawk DTC-60s from my TTC competitor (2008 Mustang GT). Bleed the front calipers (ATE Blue was pitch black...). Brakes lasted most of a session with fade near end.
Grattan has a long front straight that you come into WOT starting at the hairpin.
Going to make a 3in duct kit and go to GT rotors (13.2in v current 12.8in). Uses same caliper just different bracket and larger rotor. More rotor = more heat sink.
More rear pad bias. I was running a split pad of more aggressive front and lesser rear. Going to match pads for next time out to take more work off the front pads.
Took 2nd on both days. Beating the other Mustang by .007s on the first day! Very green track after heavy rains. Gained 1.5s on second day with some rubber on the track. 4s behind 1st place. Lots of room to gain time (brake zones). Might run this car at Nationals. TTF might not have enough cars.

Just say no to 135F+ track temps and brakes.
