If you want a good ride, not too hard and not too low I'd suggest the boge turbo shocks and lowering kit you get from GSF. I know its not a very flash kit but it sounds like its just what you want, I had it on my last car and it was a good combination of ride and comfort. You probably want the -35mm kit as thats -35 from standard height, gtis are already lowered i think its either 15 or 20 from standard height so the resulting drop will lower your car by either 15 or 20 mm.
