what to get for autox???

Thank you!!!!! I know I'm right but I'm in SM class anyway where is really suck. Lol but i love it

[iomatic]

So if I'm going to be in STX anyway, I should go crazy with mods, yeah?

SirBelch, what class did you get thrown in?

My theory is, decide what you want to do with the car and then mod appropriately. If you want to auto-x in STX class, then read the rule book and do the mods. Also, if auto-x is your goal, work on the suspension first, then power mods.

If I were building an STX Civic Si I would start with:

Progress rear sway bar
LX front bar
A good coilover set up with front camber plates
17 x 8 wheels
235/40-17 tires (Advan Neovas, Bridgestone RE-01Rs, Falken Azenis RT-615s in order of preference and cost)
Alignment
Hawk HPS Brake Pads
Intake
Cat Back Exhaust

This would be a good "local event" set-up. It would also be a fun car on the street. You ain't gonna have any street "kill" stories, and you won't win a Solo national championship, but you will have some fun.

Hmmm, I thought 17x7.5 was the limit for STX for wheels? Also, by camber plate you mean those camber bolts right? Still not terribly familiar with SCCA rules. Also, wouldn't Axxis Ultimates be better than Hawk HPS?

7.5" is the max width for STS. 8" is the max for STX

Camber plates can be used in ST* classes for the top mounting of struts. They usually allow for the max camber you can get with a strut suspension. Using camber bolts to install a coil over set up is also legal, even with camber plates. If you can get enough camber with the plates (I would suggest a minimum of 2.5 deg of negative camber in front) then I would not use camber bolts as they are known to slip. If you do use the bolts, make sure to over torque them and check them a lot.

Not real familiar with Axxis pads. If you like them, that's fine. You just don't want something that needs a lot of heat to work good. Auto-x doesn't put that much heat in brakes. You just want something better than stock. I happen to like the Hawks.

But there aren't any camber plates available for the 06 Si, no? All I've seen are those bolts that allow -1.75 camber up front. Also, -2.5 would make me start worrying about tire wear (-2 woulda been the max for me). I understand toe is the bigger culprit, but I'm unsure how much negative camber I can put in the front before it starts wearing out the rubber.

Also, wouldn't the LX front sway bar make for a less sharp turn-in, and make you have an earlier apex?

Thanks for the info though, very helpful. +1

There are Tein and Megan coil over set ups with the camber plates. I know, not the best set ups, but something to consider. I know Progress has an Si running around with their coil overs on it, but I haven't seen them in the catalog yet. I know Josh Sortor won some STX national championships on their stuff, so they could be worth looking into. So, let's say you get the Konis (when they come out for the rest of the world) and the GC coil overs, most certainly get the front camber bolts until plates are available.

I know guys running 2.5+ deg. of camber on their cars for the street. As long as your toe is OK and you keep the tires rotated, you should be OK. Not as good as the stock alignment, regarding wear, but there has to be a trade off.

Yes, a bigger front bar would give you better turn in, however the trade off is more push coming out of turns. The LX bar with a little toe out will do quite well at turn in and much better coming out of a tight corner than the Si bar. The biggest compliment I get on my car is how well it transitions. The biggest beef is it could rotate better. I'm running an HS class LX. I'd kill for a bigger rear bar (not stock legal) or maybe a smaller one in front (legal, but none available that I've found) to help the balance and get some rotation.

Smaller bar will be located!!! I NEED ONE!!

Camber plates, have been sourced, just need to test fit them. I think there camber caster plates tooo

[reaper702]

anyone know what would be an ideal PSI to have my 225/40/18 tires set at for when i go to the course?

[jdmEGO]

thank u

Now anybody wanna trade my si front sway for there LX LOL

[iomatic]

Yes, I'm going wheels, tires, sway, Koni's when they come out, but if they don't come out--Teins, maybe. Maybe.

Then, pads, rotors.

Also, I already have a P2R spacer I need to dyno-- over in Bolt-ons, people are seeing this gain as much as an intake alone, and the biggest gain is in modifying the exhaust system (H/Hi-flow Cat/E).

I think the main problem is a support group (who are not way younger than me (36)) and only want to go fast. Lots of shops here are more for that, not many are auto-x-specific, and even that subset of Honda owners is probably even smaller (PDX area), yet smaller still for '06+ Si owners. We do have PIR though, so next year I hope to see some support (they're paving it now).

My custom Bilsteins are no longer for sale.

I plan on adding a set of Koni FSD's when they become available and the Bilsteins will become the default race shock for the rear with FSD's up front.

Why not just use the LX sways (25.4mm?). Also, where you getting camber plates? I'm getting the Mugen sports suspension, and if possible wanted camber plates up front (if not I guess I'll have to settle w/ 2 sets of Ingalls bolts).

Hey, I'm older than you. I'll be 38 next month. Chris at RedShift is also 38. We're not all punk kids, we just act that way

If the photo in this thread is correct:

P2R Power Package: Intake Manifold Gasket, TB Gasket and TB Spacer

the P2R spacer is illegal for STX. You can only modify the intake to the TB. It looks like the P2R goes between the TB and intake manifold. It does look like a trick piece though.

Highrev needs to make those camber/caster plates Everyone bug Revy until he makes them.

[Highrev1]

I gotta finish the sway bar renforcement bracekets first, then I will move on to that but I just can't find the time to do it all
