i swapped out the stock rear springs for Route 66 SpeedShop 55D springs and they nicely match my Koni Yellows (about ½ turn). Car is well balanced and easy to handle on the track, wich tells me they're also a good match for my Steeda Sport front springs. The rear Steeda springs are rated at 175lbs and the R66SS55D are 170lbs with less drop. Rake is nice and looks stock, only a bit lower. Looks nice, drives nice, i like it.
