Road course/ Street My set up is v6-7 suspension some kind of AM sway bars with billet end links that came on the car do not look to much bigger then stock. Cusco front under brace front rear upper strut bars , JIC camber plates front , adjustable lateral links rear.

So far I know I need to run way more neg camber by the way at the track I am wearing the outside edge of the tires.

Wheels are 17x8.5 RE30s with 225/45 REO1Rs

You need to buy a tire temp gauge to determine camber settings... i suspect the outside of the tire will be hotter (meaning you need more camber as you suggest) Since the rest of the suspension is pretty much un-tuneable you should focus on driving before too much on setup changes.

0 Toe front and rear.

Well OEM specs for camber really are not working I am thinking about running -2 front and -2.5 rear.

how much space do you have?

I used to run -3.3 camber (front) and -2.7 camber (rear)... on my 99rs and it was lowered with race coilovers to same ride height as my Version5 springs/struts (also corner balanced). It was about 3/4" drop from stock height.

Tires were 225-50-15 / 15x7 wheels (team dynamics pro race).

With the 15's, I had plently of clearance... for the camber. On bigger tires, i'd be really close the base of the collar of the coilovers. having stock n/a power, the 15's were perfect.

here's an old pic of my car / camber on street wheels/tires.

well... every track will be different and it will change based on track conditions but... if you must

I run:

~ -3 on the left Front
~ -2 on the right front
-1.5 in the rear.

you're idea of running more camber in the rear is prob not at all a good idea. You might consider reading up on suspension design and how to use camber to get more contact patch.

What if you go CCW on the track.

Well my thoughts on the more rear camber was to have a little less under steer. I suppose clearance on my wheels will also limit on how much neg camber I will be able to run.

yeah that's not right at all. Read up on some dynamics and how alignments change the characteristics of the car.

EDIT: oh counter clockwise - Yeah, so that would be a different track setup and my numbers wouldn't apply. Hence the "get a tire pyrometer" comment above. that's where I'm starting for Summit Point - I'll adjust based on tire temps come end of practice 1.

In your original post you mentioned lots of wear on outer shoulders of front tread. Made me suspect that you've been battling understeer all along.

a little neg camber at the rear is good, but more is def not better. try a stiffer rear bar and be sure the endlinks are up to the task, that should make a big difference.

but your understeer could be result of driving issues as much as chassis setup. maybe you are bombing in and braking too late then muscling car around with the steering wheel instead of getting turned in early and letting weight transfer do the work so you can carry more speed on exit.

might be a classic case of "to go faster, start by slowing down a little"

setup on my old rally RS for tarmac was -2.5 front, -1.5 rear, zero toe F/R, plus a take-off stock WRX rear bar. sure, it's basic, but that same car running same setup just won tarmac Rally Tennessee overall.

To contribute:

General settings for me
~-2.5 front
~-1.5 rear
0 toe f/r

This is on re-01r tires though. I'm going to have to add more camber when I make the switch to r-comps.

Thanks for the help. My driving style from the first heat to the last heat changed quite a bit and I figured out how to keep the under steer to the min. I was just looking to see what people are running for camber specs. I know its different for each driving style and track I just wanted a basic idea. I got a bit of reading to do. I have been thinking about going to a bigger bar in the rear but I will get some more seat time in the car and see how that goes first.
