As others have said, get a stiffer front sway. IMO Moddiction\Saner, Gendron, Karcepts and bars similar in rates to those are the ONLY bars for autocrossing this car. The Moddiction does very well for me (Did well in BS with it and it is working great in STR setup as well) and wont break the bank as much. I borrowed a Gendron when I first got the car until I got my Moddiction bar. It certainly was a great bar. The Moddiction has suited me very well though. I held first place in BS locally all last year, got bumped to 2nd place in the last run of the last event But the car felt good wityh my setup. I am in an AP1 so I was more limited to how much tire I could stuff on the rims than an AP2.

If in good shape, the OEM shocks do very well actually for a stock setup. You could go with Koni's, but for stock springs I know a lot of people just stick with OEM on this car. You can go all kinds of crazy on this area, but I would stick to your stocks if they are good for now until you learn the car and figure out whats next.

The Bridgestones are the tire to have this year. I am running on ZII star specs right now which are great, but the stones act just like them, only they are faster. I am ordering a set of the RE-71R's for nationals this year and will be swapping them out for our practice event here before nats. The Hankooks and the BFG are still popular, but the stones and the dunlops seem to be tops for most.

As far as brakes ... for autox one of the good street performance pads is plenty. I am on Stop Techs now. They do well, but I may go back to Hawks, even with the horrible dust and noise I experienced with them before, next time just for some added initial bite.

Off topic, but anyone know what the Sanner bar is for rate. It's funny that no one mentions shocks anymore.
softest setting: 556lbs
medium setting: 644lbs
stiffest setting: 739lbs
Just keep in mind that there are few solid comparisons between different brands of bars. Both Karcepts and Gendron have either in posts or on their website included a stock bar. Since both Gendron and Karcepts use similar (the same?) spined torsion bar, Karcepts also has a degrees of twist for each bar at different settings.

Wow...we agree on everything here!

I think I'm just going to try 225/255 Re71r and just run the Eibach for now. Also, I just ordered Cryo treated full face Centrics and the Hawk Street Race pads. I figure I can run this setup for a year, get a good feel for the car, and then look into some higher quality parts later on.
Sounds like a plan...is that the new DTC-30-based Street/Race pad? It is supposed to be derived from the DTC-30, which is often used as a rear pad with a DTC-60 or DTC-70 in front in race cars (e.g. Spec Miata). The few reviews indicate noise and dust are at HP+ levels. Some reviews: http://fiestast.net/threads/hawk-str...d-review.2262/, http://forums.nasioc.com/forums/show...1&postcount=26,

Did you consider the Ferodo DS2500 or CL RC5+ sintered pads?
I haven't considered those yet. I used HP+ on my old STi and I liked them a lot. Even with all of the noise and dust.i heard that the new compound on the Street Race gives less dust and less noise but you get more initial bite and higher temp rating that the HP+.

There is one review of someone autocrossing the DTC-30 and they loved it. Overall, lots of people like the DTC-30 as a race pad and it has among the highest coefficient of frictions available in a low operating temp pad. The Ferodo DS2500 is a known reasonable compromise...no complaints from anyone using them...but don't offer the bite and maybe not as good engagement and release as the Street/Race pad.

I think I'll try the Street Race pads and see how they do. If they are too dusty and noisy I may look at those

interesting thread.
my setup for B street. RE-71Rs, 245/255. Gendron, 2 3/8 hollow on 3rd to softest, 0 toe and -2 camber on the front and 1/16 toe in and -2.2 camber on the rear. Re-valved Konis, usually 1/4 turn from full hard on front and 1/2 from full in rear but on rougher surfaces I add 1/4 turn from full hard. I really like the sway bar setting and the alignment but not so sure about the shocks. I haven't found any adjustment that really works much better than anything else. Not really sold on the Konis. Maybe I should go back to OEM for comparison.
I get a bit of under steer in the middle of sweepers but turns in good.

Would like to be able to get on throttle sooner coming out of sweepers. Might need to take away a bit of rear camber so I can induce a bit of oversteer. Any suggestions?

Curious on their street race pads as well as I have not used them. Remember that regardless of what pads you choose, stay away from an actual track pad for an autox car. You dont have a good chance to get them properly up to temp sometimes ( you can do some brake dragging, stops on the way up from grid, but typically not much) so you may actually be worse off with a full track pad. Getting brakes too hot is not really a problem in autox, so you dont really need a full track pad. The street/race, performance street, etc are generally where you want to be for this sport.

Have you tried softening the front damper rebound setting (the only setting you have on Konis)? Do it in a very large increment to test, as small changes on a damper are not always easy to feel at first. So try something a bit more dramatic and see how it works.

I remember that the HP+... Even cold... Had outstanding initial bite. And I read that these new Street Race pads are about on par with them in terms of cold operating temps but have better track/high temp performance
