If it is anything like the S30, it's a lotta damn work without much pay-off. I may be preaching to the choir, but if you have a stock car and want to make dramatic changes in the firmness and handling of the car, I would do things in the following order: wheels and tires, steering coupler and rack bushings, 5-point harness, springs and shocks, bleed brakes and get more aggressive pads (only drawback is dirty wheels). Then and only then would I do suspension bushings. Actually, I would do a motor swap, and THEN do bushings. Crap, do an LSD before the bushings, and camber plates too. The contribution from bushings is minimal at best. Heck, I'd even put a fat tailpipe on it first.
