i run on a asphalt track and a guy told me to cut off my a-frame mounts and move them
the way i understood him was i want the rihgt side top ball joint leading the bottom ball joint about a 1/2 inch
and on the left side i want the bottom ball joint leadig the top ball joint

and on the rear i need to take the right side bottom control arm off and cut 1/2 inch out of it and weld it back
what will all this help?
or is it the wrong thing to do?
any input would be appreciated
thanks, bubba

Bubba, I used to race Street Stock asphalt and now am learning from these guys about dirt. First, I don't think you've given enough information for anyone to give you advise. What chassis, 79 monte?, 74 T-bird, 88 Caprice?. Second, there are easier and more prudent ways to adjust caster and camber than cutting and re-welding your a-arm attachment points. I personally would not do it without having a caster/camber, bump steer gauge and a lot of time available.
Third, I would never cut and reweld a lower control arm. Your buddy's fixes may work with his car.... but I'd never do it to mine. I know that if I made the adjustments he recommended, I'd hit the wall in turn 3 the first lap out.

One of my buddys cut a 1/2 inch out of his right side rear upper control arm and he says it gave him more forward bite and helps the car turn in corner. its a 1/3 mile dirt track and a long body malibu I dont know if this is the right thing to do but he says it helped him.

So basically he's saying negative caster in the right front and positive on the left?Sounds backwards to me.

my car is a 77 monte carlo and its been cut down to 108 inch wheelbase
i run a class that has no rules except no aluminum heads and we have to run american racer tires
we didnt have enough cars to run so they let us run with sportsman
the sportsman has alot of rules and they kicked our butts
i know i have alot more motor than them thier just handling alot better
the track is 1/4 mile very high banked and
thier track record is 12.01
average speed is around 80-90 miles per hour
so i need to work on the setup is why i asked you that question,"just 2nd year racing"
