I have the Eibach Pro-Sports, they were around $250 if I remember correctly. I would do shocks while they already have your suspension tore apart. I enjoy my D-Specs, I think I paid $550 for them. I set the rear almost completely stiff, to help prevent rear end sag. I also did the GT500 strut mounts which were around $60-$70.
The tires were about $240 for the front and maybe $280 for the rears, not sure. I just ordered them as a package from my dealer...$2800 when all said and done.
255/35/20 in the front and 275/30/20 in the rear, which was the biggest mistake I have made, but thats what the dealer recomended.
I would go 275/35/20 in the rear, because the rear sidewalls are actually shorter than the front, and it's disgusting. only 1/2 total, so 1/4" on each quadrant of the rim, so not terrible I guess.
And yes, Iget many compliments on the stance of my car.
Thanks for the compliments!
