I actually haven't installed the rear biltsteins yet. The 1" cornfeds havent "bottomed out" on the stock shocks at all. Course I haven't been doing any off-road either. I'll change them eventually. For now no need with the new stock shocks on and rides great. Spidertrax really give you that...
1" rear Cornfed's with front biltsteins @ 1.75 with spidertrax spacers handle as near perfect I could ask of my DD. May go up a bit once I get new shoes but even with stock tires the ride is nice with my setup. Toyota should have made them all this way from factory. Imo
