I got IE camber plates and sways. Have only been on the track with them once, so I’ll let the more experienced guys address which they think is best.
The IE plates seem to adjust OK, but the installation would have been extremely tough without the help from posts on this forum. The spacers between the strut shaft and bottom of the plate had me scratching my head for a while. I chose the IE sways because they came with the reinforcing plates that others didn’t seem to include.
As for what else to do “while you are in there” . . . On the front end, you may want to go ahead and install new control arms and bushings and tie rods if you haven’t already or aren’t sure how good your existing ones are. On the rear, there isn’t much else to do, unless you want to tackle the trailing arm bushings or subframe bushings. If you get the IE sways, you will need to drill the trunk floor to attach the brackets and reinforcing plates. I made a cardboard template of the bracket to locate the holes. I chiseled all the tar out of my trunk before I did that, but if I did it again, I might leave the tar and just cut out a spot big enough for the reinforcing plate. The racers here say you need the weight of the tar to be legal, and having it in the rear helps balance the car. It weighs about 42 pounds.
