A while back someone posted Alignment specs for camber caster and toe for a good road race setup for a camaro. Does anyone have these? Thanks!

i use -2* camber most of the time. i've tried a bunch, i think -2 is most responsive for my setup. i'd get a set of adjustable lower control arms if ya don't have them already, that way you can fine-tune the others yourself. there is no defined number to make your car handle best, it all depends on how low it is, what speeds you'll be runnnin, etc. etc.

Rob, are you saying that you do alignments? I know your in orlando, I just meant a shop in the Sanford to Orlando area. For my setup as much negative camber as a person can possible get is better. The stock control arms don't provide much adjustability. I've got coil overs to adjust ride height but that shouldn't play much of a part.

Can you recommend one for AX that is also DD'able? I'm running 4 Eagle F1's, 275ea.

well it all depends on what you are lookin' at when you say "DD". all of the specs are DDable, the only question is how much tire wear you will see as a result. for DDin i would stick camber somewhere between -1 and -2 and leave the rest alone. camber makes daily drivin easier IMO cuz you can blast around turns and is much more responsive. with my setup, my front and rear tires need to be replaced at same time, because the inner patch of tire goes bald same time the rear tires go bald. you could get some cheaper tires next time. you dont need the f1's and wont feel so bad tearin them up. with camber set and cheap tires, your car will handle way better than 0* w/ eagle f1's.
i didn't catch that you wanted to AX. . .all the above is true and camber-only adjustment will still make for an awesome AX setup. . .if you know you are going to AX many times on a set of tires, i'd set it -1.5 to -2. -1.5 would prob be your best balance between excellent handling and decent wear characteristics, but you will definately rail some turns better with -2 or -2.5 even. because autox tends to be slower, sharper turns you want a decently sticky rear tire so you can really plant those front wheels without losin the rear. i know this is a bold statement, but there is no car that is not a supercar (vette included in that) that will beat an f-body in fast turns because of the giant stance of our cars. unfortunately there is a trade-off to that. . .slower turns are dominated by the smaller cars so you gotta try to make up for that in AX with extreme camber adjustments. im rambling and don't wanna feed you info you dont want/already know so im just gonna stop now and let you ask if you want more info.

On a 255/50-16 Toyo, my 3100lb car liked -1.5* camber and zero toe.
I've since moved to 275/40-17 and the car seems to want more negative camber. I've moved it to -1.9* and am moving 0.1" toe OUT. The car wants to skate a little on turn in.

I imagine the reason you ask is because you are wondering how I get that much negative camber.
Simple ... elongate the slot on the K-Member.

nah i run -2 most of the time myself. . . .i was wondering that because you originally said 255's. . . .i've ran -3 but there is a rod end at every mount on my car, pretty much.
nice to see someone racin' their f-body, nice car.

Ah ... A 255 toyo had almost 10" wide contact patch. The reason we ran it.
And thanks for the compliment. I've been fortunate over the last couple years bringing home a regional Championship trophy both years.
This year is gonna be a LOT tougher ... lots of fast cars this year.

you still runnin an LT? do you race anywhere outside of texas?

Yes, still have an LT1. It's a great motor. A SBC can take a crapload of abuse. Just keep it lubed and keep it cool ...
I've been to No Problem raceway outside of Baton rouge once and make an annual trek to HAllett Motorracing Circuit outside of Tulsa, OK each year. I've also raced at Pueblo Motorsports Park in CO once. And I was crew chief to a podium finish twice at Nationals in Ohio. All in CMC or CMC2.
I cannot say enough how cheap it is to go WtoW racing. I was so scared of beating and banging the car up. And while it does happen, incedents are far and few between. I began racing in 05 and had my first "significant" bady damage last weekend. And it's hardly noticeable.
I spent less that $3,000 running 26 races all over Texas and Oklahoma. That includes travel expenses to and from, food,, tires, brakes, fuel ... everything.
I have about $13,000 in my car, spread over 4 years. I have about $2500 in safety gear like helmet, suit, HANS, nomex, shoes and gloves.
The first year, it's a tough check to write. But now I spend less, a LOT less, on my race car than I ever did on my street car.
