Hey, yeah they did paint and finish for me but only because they are in dubai and so I am. there was minimal prep and finish required as with anyother bodykit then paint matching and paint
Kevin, it doesn't take long to install the camber arms if you already have the car up a lift and the wheels off. 30 minutes max for the front, less for the rear.
The rear springs are easy to install, 1 bolt and you can drop the spring out and install a new one. The fronts are hard to install as you must remove the complete strut, (7 bolts per side, some fiddly), and then use a spring compressor to separate the spring from the strut and then reverse the process to reinstall. About 2.5 hours. If it was a complete coilover it would already have the spring installed so it would take less time. If they did an alignment as well then I can see everything taking 4 hours total.
