Default STH Guys Check In and Setups

Seems nobody has started an STH class setup. Post what you're running.

1. Engine/Power
2. Exhaust
3. Suspension
4. Alignment
5. Wheels/Tires
6. Brakes

Plans/Results/Misc.

I'll kick it off:

1. Grimmspeed EBCS, Walbro 255 fuel pump, Silicone inlet, IAG AOS, Full protune
2. Divorced Downpipe, full 3'' borla turbo back
3. ISC N1 coilovers with 8K front 7K rear swift springs and rear camber plates. 25mm Perrin rear sway bar & Stout Mounts, 22mm Whiteline front sway bar, kartboy endlinks.
4. Camber -2.5F/-2.0R, 0 toe all around.
5. 245/40R17 RE-71Rs on Enkei RPF1 17x8 +45
6. Hawk Hps brake pads, slotted rotors, 4/2 piston because 2007 wrx, Braided lines and Motul fluid

So far I'm middle of the pack in my region. I mostly need to work on driver mod. Next upgrade is intercooler for less timing being pulled on later runs in the afternoon when it's hot.

The EBCS and fuel pump are not allowed in ST. Intercooler is for STH, but read the rule carefully before selecting one...

Good catches, I haven't been doing enough events to have anyone protest as I wouldn't have the points to get into the top anyways, but these are good. I don't "need" the 255 considering my current mods, it was more of a future proof mod while I was in there changing the filter. I could remove this if I think I may actually be getting close to competitive. With the EBCS, is this line below what makes it not allowed? Kind of frustrating on that one since I just feel safer having the EBCS vs stock to make sure I'm getting accurate tables.

"F. The engine management system parameters and operation of internal

I'll play. But don't follow my list. It was a daily driver for years prior to getting into autox. 4EAT too.

1. Perrin turbo inlet, Cobb intake, Torqued solutions after-MAF tube. AP OTS stage 2 tune (lol).
2. Cobb turboback
3. Excel-G, USDM STI pink springs, 24mm rear swaybar, Whiteline camber bolts
4. ~2.1 degrees camber up front, 1/4 inch toe out front (adjustments seized). No idea in the rear.
5. STI 5x100 17x7.5", 225/45/17 RE-71R
6. Centric blanks, Stoptech Street pads

145k miles. Eh, it won both my local regions last year. The 4EAT makes it a bit less fun, but you can shift it manually for autox, which helps. The tires helped A TON. I think it really needs coilovers and a front swaybar to be better. With the Fiestas, they're hard to beat now.

I've been looking for a manual BRZ for over a year now, but most are overpriced. Debated going to Miata crowd, but I've owned Subarus all my life, so it feels wrong.

Once you leave Subaru and take a Miata around a track the only thing that will feel wrong will be your brand loyalty to subaru.

Meh - BRZ is a capable track car. Miata is as well, but it isn't for everyone. BRZ has room for tires in the back seat :P

I just love the go cart feel of the Miata. I've been eyeing them up for an Exocet project as well.

Anyone have any tips for reinforcing/stiffing a basically stock '18 WRX so that it stays within STH?

You could try running a CVT WRX in autocross, as that's basically a AWD go cart =D
