On our '82 Monte Carlo we just built, we are currently setting up the caster & camber. After setting the caster with the appropriate shimming, I went to set the camber. On the right side (passenger) I have shims that are stacked where I only have about 2 threads showing on the end of the bolt to the edge of the nut. This is on the upper control arm, rear bolt. I need more camber so I guess if I get a 3" long bolt for this I can add more shimming to the front and rear bolt to get more camber. The only problem is that I'm not too very far from the rear of the upper control arm hitting the exhaust manifold, any ideas? I have stock upper and lower control arms. On the left side (driver) I want to get a degree and a half or two more of positive camber but after setting the caster, there are no more shims to take out on the front bolt. It almost seems like if I could shove both lower control arms right about 3/16" I'd be set? We have to run stock control arms. Any help on how others may have dealt with this? For those who are wary of a thick stack of shims, I'll make a solid block with a hole after I get my final measurements.

I'm trying to get caster:
+3 degrees L.H.
+5 degrees R.H.

Camber:
+2 degrees L.H.
-5 degrees R.H.

Thanks,

We move the ball joint out a lil on its mount by moving the wholes on the drivers side. They do make a a-frame cross bar that is offset also. Carquest used to have it calling it the problem solver cross bar for upper aframes. Not sure where to get them now. Got spares and haven't bent any in a while. I'll try to get the part #. I had the same prob and know these work

There is room on the lower mounts to move the bolts about 3/8 of an inch. Any less than that isnt worth the effort.

on the right side where the ball joint goes we move it toward the motor by die grinding the big hole and drilling new holes for the ball joint usally get about 1 to 1 1/2 degrees. on the left side its a little harder but with some help and a welder. take the upper off and where it bolts on done about a half to 3/4 of an inch below the bolt holes and cut it off with a cut off wheel not a torch . make a nice straight cut, then place a peice of 1/8" thick by 3/4 flat stock and weld it in on the frame piece, then take the other piece and weld it back on top of the flat stock and slide it away from the motor about a half an inch and weld it in .that will give you more then you need. hopefully i said this how i thought it and it helps and you will never know by looking at it and people will tell you your front isnt setup right because you shouldnt have that many shims on the left side ,just agree.

Not trying to step on your toes Bob, but your idea is only good untill you get hit and bend a control arm. then what? I prefer to move the lower mounts and use stock parts. that way if(or more like when) I bend an upper I can throw just any old metric arm on and the toe will be close enough to run. The guy that won points last year had the upper arm redrilled on the right side and when he bent one his spare was not redrilled. ended up with alot of extra work to reset camber and toe.

I knew Behmer wasn't legal. Guess I was never told that the rules were optional. Time to throw in the old 434

actually there isnt anything in the rules against running chevelle spindles on a metric. Heck Ive got em on mine. Bigger brakes, bigger bearings, and better geometry. Why not?

I quote " Suspension must be in stock location, and be mounted to the stock frame for application or make of car." also says the ball joint must be in stock location. From my perspective that means a metric car should have metric parts. Maybe I don't go into the gray areas as much as I should but whatever trips your preverbial trigger.

Funny story: I was at Hasse Racing about a month ago and Todd V. was there and we were talking racing and he said. " Do you race?" I had to bite my lip to keep from laughing. I said yes I do, but I didn't tell him that this would be my 4th year (3rd in S.stock)and not even one person, for tech or saftey purposes, has ever looked at my car. Maybe if I would run up with you guys more they would look at it.

Fairlaniac- not wanting to rock your boat, but your camber settings are a little excessive based on what I've used on dirt for the last 10yrs.I recommend +1 on the left and -2.5 to 3 on the right. Of course this is based on you using eurathane or steel bushings in the upper and lower A's, which I highly recommend. It would scare you to see how much those arms move in the corners with the wore out stock bushings....

i'm confused ryan,which car is yours?The #3 is pretty butI had an old car that was fast just ugly so in the off season i put on a new skin,it looked good until the first race and then it looked just as bad as the year before maybe a new car get's everyone's attention and they accidentally run into you.

I am #3. Its not a new car just a new body fenders and one door is from a cutlass the roof is a monte and the rest I made. At our track they run into you no matter what your car looks like.
p.s for those who don't know who I was talking about earlier it is our tech guy.
