Over the summer while building up my suspension, I decided to tackle the issue my car has with having a useable camber adjustment range for the front of my car (97 Mitsu Eclipse AWD turbo; it has none basically). After some research, and talking to a lot of other fellow DSM people that autocross or road race, I combined ideas some people were doing separately into one.
I took my stock front upper control arms off the car, cleaned the rust off with a die grinder and steel brush bit, then had them media blasted. I coated them with anti-rust paint. I then pressed out the stock ball joints and replaced them with SPC’s Adjustable balljoints. These balljoints can be set +/- 3 degrees for camber ( rotating the ball joint mount in the slot to set either positive or negative) with the “camber plate” and bolt on top.
I also added SPC’s adjustable anchor bolts, and reversed them to add -1.5 degrees of camber adjustment. If you put them in the normal the adjustment is positive instead of negative. You will need the smaller bolt, as the bigger one is too big to be reversed. Here is a pic showing the difference between the two:
You want the camber bolt on the LEFT for this project
Here are pictures of the finished product:
The result is +/- 4.5 degrees in camber adjustment for the front. With proper suspension tuning, I think some of the inherent characteristics of the 2G can be corrected or remedied to make the car easier to flick and turn. The trick will be to get the adjustment while keeping the toe and caster within reasonable spec. This will take some work. I’ve got access to a friend’s shop, so we will be doing this once our schedules clear up.
To compare, cost for a dedicated adjustable control arm from SPC (or any other company) ranges from about $650-800 for the pair of control arms. The SPC arms have a +/- 6 degrees of adjustability. So the solution I used is very cost effective, as I have very similar adjustment for less than half the price.
