Third Gen Camber Settings?? - F-Body Road Racing and Autocross Forums

Friends,

My 1987 IROC Z/28 is a dedicated race car. Trailered to the events and not street legal. Given that I drive on Goodyear GS-CS R Compound tires what is the best setting for the camber using stock strut mount plates??

I found some third-gen specs which state -1.75 is available using the stock plates and that is the recommeded settings for Road Racing.

I am headed off to buy a Camber tool to measure the settings and move mine in quite a bit. Does somebody have a quick howto on this?

I think the steps are: (from observing others on other cars, but I want to know the *REAL* fbody way to do this..)

1) jack up the front end, take off both front tires.
2) put the camber tool on the rotor
3) loosen the 3 upper strut bolts and bring the strut IN at the top toward the engine (using the tool to ensure 1.75 is setup. PERMANENTLY MARK the location of the plate with paint. (paint body/paint bracket so you can line them up later without the tool).
4) loosen the 3 upper strut bolts and take it to the max, measure and mark that, re-tighten the bolts.
5) mark several places along the strut tower with measurements on both sides so that you can play with settings during test and tune.
6) lower the car
7) try it and then try the different settings until you find what you like.

that is kind of MY process, is it right? what is missing?

what have you guys found that works best for autocross?

Brian

I just jacked it up from the cross member, took the wheels off and loosened the strut mounts just enough to move them. It was easy and no prying was needed. Of course after you make camber adjustments you have to let the car down and roll it at least 10ft or so then make your toe adjustment and repeat the roll for good measure on your level surface. If you try to adjust it while its on the ground it is indeed nearly impossible without specialty tools. Believe me I've tried. It'll shoot your camber adjustment as far negative as possible as soon as you untighten the struts mounts enough.
