i'm not interested in how they look, i'm interested in more grip.

i notice that there is the option of some 17x7.5 +55 wheels. i can get some nice light 17x8 +50's, or some +45's.

is 8.5 inches of rim madness? i'm not going to be running a stretched tyre - it'll be a 245/40 or 255/40 with the 8.5.

car will be on mild lowering springs (dropped about 1.5 inches at most) like eibachs or whatever.

i'm also interested in what springs to purchase - i'm essentially after the lowest spring rate aftermarket springs that are out. i can't find the spring rates of eibach pro-kits & H&R seem to be about 300lb/in, which is far too hard for cruising.
