[H1C]

Thank you to everyone for sharing your setups -- it's interesting to see the variation.

Here's mine; I don't go to National events and probably won't ever be able to. But my car, driven by my friend who's the best driver I've ever known, won our region's SCCA championship last year in it. He raw-timed the current/multiple Dixie Tour STU winner, and was several seconds ahead of the current/multiple Dixie Tour STX winner, both of whom are great guys and better drivers than me.

Engine
K&N filter stock airbox
Tomei EL header and over pipe (OP makes a noticeable difference in how freely the engine revs. Also seems to bog less at low rpm in 2nd. Will have to go back to the dyno to see what difference it made.)
Stock front pipe (Motiv HFC FP might go back on if I can get a quieter exhaust)
Ark Design dual canister exhaust.
Wayneroms v146.3 default version, rich +2% file

Suspension/chassis
MCS 1WNR, 11/18 clicks F, 10/18 clicks R
Eibach springs 6" 500 lb/in F, 7" 450 lb/in R, no helper springs
Ground Control camber plates, rear top mounts, F strut brace
Cusco R shock tower brace
Whiteline RLCA with inner bushings set to raise roll center
Whiteline subframe bushing inserts
Perrin 22 mm front swaybar on stiff, Racer X endlinks
Stock rear swaybar
Perrin steering rack lock-downs (not legal for National events I don't think, but holds alignments better since I installed them. The front toe used to change after every event before getting these.)
Tirerack FF10 17x9 45 et
RE-71R 245/40
Ferodo DS2500 pads, Ate brake fluid
Racer X master cylinder brace

Alignment
3.5 - 3.6 camber F (I get most of my camber via the slotted strut, probably less than a degree from the plates)
OEM caster 5.7 - 5.8
0 toe or as close to it the tech can hit
2.8 - 2.9 camber R
0.1 deg toe-in per side or as close to middle of the factory range the tech can hit

Ride height
Two finger gap in R, maybe a little more than that in F
As close to 0 rake as I could attain in my garage with its lumpy floor
Front spring perch height set equal L to R (basically as low as they could go while keeping the springs captive at full droop)
RR spring perch 2 mm lower than LR
Corner balance was acceptable to me in this configuration

Interior/Misc
SRP accelerator pedal
Schroth Rallye 3 harness
OEM length ARP studs, hardened steel lugs (my favorite mods after snapping 8 OEM studs with OEM lugs frozen on them)
Bosch size 51 AGM battery, JDM smaller tray and tie-down
