I'm going to install it myself (as I did with my springs) it'll take max two hours and its easy with coilovers cuz you dont need a spring compressor to seperate the the shock and spring. Just jack up the car, un bolt from the the strut, hub and sway (front only) then bolt back in. It's pretty easy. Then just get a wheel alignment, usually 55 bux for a 4 wheel alignment at the tyre factory.
