This Shocktek kit is very noisy. Lots of play in the front, which makes me wonder if there's missing bushings/spacers in it. The strut nut bottoms out before it tightens up on the camber plate, leaves about an 1/8" gap, which becomes very noticeable over bumps. I took it apart and there's a gap between the strut shaft and top hat, it's not a snug fit at all.
However, while I had this out, I busted out my old S13 Tein coilovers to compare.
They look usable. Spindle bolt holes line up, only difference is they are further out from the shock body compared to the Shocktek. I wish I had a stock strut to measure.
Either way, I tried one side, and it fits great, just had to bend the brake line tab or it hits frame. It tightens up nice, without any play. I'm guessing because of the distance the spindle sits now, it toes out the wheel. Tomorrow I'll put on the other side, adjust the toe, and see how it drives. I still need to figure out the back though. If I could just get a threaded sleeve made for the back shock to thread into, and weld some spindle mounts, I'd be all set!
And just out of curiosity, has anyone successfully used S13 coilovers on a B13? I know its silly with all the available options, but since I've got these laying around, no point in letting them go to waste.
