Default [Auto-X] What's your STR setup? 2018 Edition

Literally just finished my build, so figured this was a good time to start the 2018 thread! As per last year:

No, previous owner was an enthusiast, but had never autocrossed. (He actually put on RE-71Rs, HP+ pads, and switched to performance fluids, but it was all like new. I got good use out of those tires on the stock wheels over the past year!)

Re the CR lip: according to section 14.2.F.1 of the Solo rules, aero parts are ok if, “It is a production part which is standard or optional equipment of a US model of the vehicle.” I've seen various seemingly informed opinions on whether the CR counts as "a model" of the S2000, so I've submitted a request to the SEB to clarify. If not, I'll just pick up an AP2 style lip off of eBay.

CR lip is ok on a CR, an AP2 is not a CR

It wasn't a production part for 2006 though and even if they don't factor in the year model as a limiter, I wonder if they would require a complete conversion in keeping with the A/B Street classification (CR is A Street). I'm curious what their response will be, so please give us an update when they respond. If they'll allow it, then that opens the door for running CR aero front to back for STR.

Yep, I'll definitely post a thread with the result when they rule. Let's keep this one to builds though!

I'm not competitive on a nationals level but usually fair well locally, my car is also a compromise to do a number of things well.

MODEL: 2006 Honda S2000


SUSPENSION:
  • Fortune 510 double digressive custom valving for 12k/10k, no helpers necessary- dual duty for track, autocross, some street driving.
  • Saner front bar
  • Stock rear bar
  • Prothane compliance bushings
  • Megan Racing camber joints with RCA plates omitted for STR compliance
WHEELS/TIRES:
  • Enkei RPF1 17x9 +45 with 255/40/17 RS3 for funsies. 255 RE71R to replace them after the car is sorted.
BRAKES:
  • Powerstop Trackday Advance pads - work okay in the hotter summer months, but definitely too cold in the first few events to get heat into them. Have a set of Stoptechs that I may throw in. Stoptech rear slotted rotors. Centric high carbon/cryotreated front rotors
ENGINE:
  • Insulated K&N FIPK, box made from corrugated foam board and insulated, lighter than K&N shield, seals up better, and seems to keep IATs down.
  • Berk Headerback with HFC and resonator added
ECU:
  • Flashpro with tweaked Toda tune.
SEATS:
  • Currently stock, have Buddy Club and some fabbed up Recaro sliders on Wedge bases. I have a Sparco Evo 2 in the office, a bit too big for me, but if it fits okay in the s2000, I might just throw it in anyways until I can find something more suitable.
MISC:
  • CR front lip from previous owner (waiting on SEB ruling)
  • OEM AP1 trunk spoiler
  • OEM hardtop
  • heavy Blox shift knob
  • carbon fiber chip guards to prevent the leading edges of my fenders from being chewed up by detritus.
  • Spats on track, usually removed for autocross though nobody seems to care enough to contest it.
ALIGNMENT (TBD):
  • Front: Camber -3, Total Toe 0, Caster 6.0
  • Rear: Camber -2.6°, Total Toe 0.14 in
HEIGHT/WEIGHT:
  • ~12.7" center to fender
To Do List for 2018:
  • Find a seat
  • If CR Aero is legal, I'd like a CR wing
  • Possibly build a stepped intake
