moving metric rear upper arm mounts

[stockcar5]

I've run low rear % setups in the past and i currently run higher rear %. The low rear % and the more lever rear lower arms was ok but no better than what i run now. I have a hard time finding spots to put any more lead to even get my rear % low enough to work with level control arms.. I have all my lead in front of the rear end now and still have 56 rear.

I played around with this and had good luck with it. What I did was this: I simulated the ride height of the car as it went through the corner, did this by taking springs out and lowering car to where the travel indicator on the shocks touched. I then leveled both rear arms on the chassis side and drilled mounting holes. Car worked great and is still a winning car today. As long as your ride height isn't anything too exotic, the left upper will probably be close keeping in the stock hole. Just remember if u make a ride height change, its going to change your arm position a little.
