finally found a set of the GTU rims so i need to get some rubber for them, i not sure if i should go with the 40 or 45 series sidewall?? any suggestions? i'm most likely gonna get the 45 series just so i don't bend the rims on the sucky PA roads.

I prefer 40's for looks and handling.

bettween the two, go with 45's. i got some 225/40-16's that came on some wheels i got. way too tiny in the wheel well. 225/50-16's fill it up just right at stock height. 45's would probaly do if you're going to lower it some.

start where you are,
use what you have,
do what you can.

cool, its already lowered 1.5" with suspension tech springs all around, but once i'm done doing the brake swap and turbo motor build up i plan on getting Held front and rear coilover kits, so for now it should look pretty good. thanks for the suggestions.

yes, 40's are a tad too smalll, go 45 for sure
