I'm gonna start the installation of my tein ss w/o pillow mount on my coupe, but I need some help. I need the oem top mount. Will I need a spring compressor? I was thinking of just taking the bolt on the top mount bolt in the middle off then lifting the car up so there is no need for a spring compressor. Will that work? And for the tein ss coilovers, can you adjust the height just with the wrenches or will you need a spring compressor to raise the ride height or to lower it?
