Rears look like they're over-inflated, worn out in the middle vs the edges. What PSI are you running them at? Did you get a quality four wheel alignment after installing your coil overs? Are you at stock ride height or lowered? If lowered, did you do alignment AFTER lowering car? The wear does look a little lopsided, but the middles are far more worn than the outside, so that screams over inflation.

Agreed with hEaT.
If your tires were at 32psi, they were underinflated. Under normal circumstances (alignment being right, weight distribution being normal, etc) then at 32psi consistently, you'd see the outer edges wear evenly and the inner not wear as it wouldn't be making as much contact. Now that you're at 35psi, you'll notice increased wear in the middle until you fix what else is wrong.
I am by no means a suspension engineer, and I know nothing about Raceland suspension and the quality of their products. But, if you have coil over suspension and you have the car slammed, that's going to do interesting things to the rest of the suspension. It's going to put it normally at the extreme end of it's travel, as though it's always responding to a bump. That's got to ruin your ride quality first and foremost, and secondly may be putting a lot more wear on the center of the tire due to positioning.
Again, I'm not an expert on that. So I'd take it to a good alignment shop, preferably one that has experience with race cars (if you have a dirt track in your area, or any kind of amateur racing, find out who they go to for alignments. More than likely there's a shop that at least sponsors a car, if not owns one. I know in my area, I go to the alignment shop of a guy who has a dirt track car, and he's the best alignment guy I've ever had. Very consistent, very fair in price, and won't align a car that has worn out parts as once you replace them, you just have to come back and do it again.
