SCCA Solo C Street Discussion

Here's my current list of mods. I'll have to take some off to be in C Street, which is a better plan for me given the ol' budget. (This is my DD)
- Grimmspeed cold air intake (remove)
- Grimmspeed front strut tower bar (remove)
- Open Flash Tablet (reflash to stock)
- Eibach Pro Springs (possibly buy Konis and a used set of stock struts)
- Stoptech Street pads (keep or upgrade to more aggressive pads for events only)
- Whiteline front camber bolts (keep)
- Enkei RPF1 17x8 with Hankook Ventus R-S3 225/45/17 (possibly put Hankooks on the stock wheels?)

Question on tires:
I think I read somewhere in the 2016 rulebook that the tires have to be less than 2 years old. Is that correct? I bought the wheels and tires off a guy on Craigslist and he'd had them for a few years so I think they're 4-5 years old.

Pads and camber bolts are the only keepers. You can not use the TRD bar (or springs) since you have a BRZ. Those tires on stock wheels is certainly an option, but it's not the setup to have if you want to be competitive - especially if they're that old.

The other option, given the fact you'll not be competitive as-is, would be to just run the car you have now in STX and see where you want to go with more time in the car competing (I'm making an assumption, perhaps you've done that already - in which case disregard.)

Thanks for the input cjd. I might try running what I have in STX and going from there, knowing it will be a learning/growing season.

The only camber bolts you can use in Street/Stock are OEM. The White Line bolts allow too much camber.

It goes 57mph in 2nd gear and of course the hard limiter with stock tune.

The thought was you could run the taller 235/45 tires to add a little bit to the top end. One of the better autocross runs I've seen on video is Ogburn's from 2015 nationals where his fast run on one side he shifted 4 times on course. A 2017 probably would have been a better car and you would be shifting just as many times. Shifting that many times leaves no real margin for error though.

Yea good point. I remember that run as well, I know I couldn't shift like that and make it work

NO - Open Flash Tablet
NO - Eibach Pro Springs
YES - Stoptech Street pads
NO - Whiteline front camber bolts
NO - Enkei RPF1 17x8

NO - Tires have to be less than 2 years old.
YES (FR-S only) - C-Street allows me to put a TRD rear sway bar on and still run an aftermarket front bar?

[DocWalt]

NO you cannot run a TRD rear bar and an aftermarket front bar... because you have a BRZ. If you had an FR-S you'd be OK doing that.

[pszuvela]

Well I'm getting conflicting responses on the rear TRD bar and aftermarket front bar from Locust and DocWalt...

I'll be the tie breaker. No TRD bar on a BRZ unless you want to run in STX.

TRD parts are CS legal only for the Scion FRS. The Subaru BRZ cannot use TRD parts in CS. It's a stupid rule, but it's a rule.

Well I didn't notice you had a BRZ so no, you can't do it. Just assumed you wouldn't be asking about the TRD stuff if you had a Subaru instead of a Scion.

[pszuvela]

Got it. Thanks for the clarification everyone.

[Shark_Bait88]

I mean... you can use a TRD bar, but just one and no other sway bar upgrade.

Has anyone tried 225 front 245 rear? My car is completely terrible on launch. We run on sealed slick asphalt and gets no forward bite.
