HELP with ZO6 WHEELS

I have a 2000 SS M6, with sportline springs, and I just ordered a set of Z06 rims 18/9.5 and 18/10.5 both ith 53mm offset- w/ 275/35 and a 295/35 tires. Will I have any rubbing issues? and does anyone use spacers?

For OEM C6 rims (79mm rear offset) I'm running 1.25 inch wheel adapters for 295/35-19s. These bolt to the hub and the wheel bolts to the studs on the adapter. 53mm is not a severe offset for our cars; someone correct me if I'm wrong but I think the factory offset is 50mm. The only concern might be the rears if you are lowered significantly.

The 53mm offset will push the wheels out enough to preclude use of the BFH, it will (IMO) look better than the more tucked in 56/58mm offsets, and it should clear the fender lip on most applications.

With that said, though, the Sportlines are soft springs and they're real low in back so you'll want to be sure that the fender lip doesn't rub the sidewall of the tire when the suspension compresses. Best way to check this is to put a couple jackstands under the rear subframes letting the axle hang, pull the rear springs out (assuming they don't fall out on their own

), then put a jack under the pumpkin and raise the rear until you hit the bumpstops. You should be able to gauge your tire-to-fender lip clearance easily this way. If the fender lip hits on one side only, you can use an adjustable PHR to center the axle better. If both sides hit or are very close then you'll need to roll the fenders to prevent cutting the tires.

With regard to spacers, I use an H&R 5mm spacer in the rear for an effective 48mm offset - looks and works great. Just make sure you get at least 6 turns on your lugnuts and get a nice hubcentric spacer. Just be aware that the further you push the wheels out the more likely you will be to have to roll the fenders.

Where are you finding the 53mm offset at? All I see for sale are the 56 and 58mm 18x10.5s. Thanks for any help!

i had the same exact setup as you before i changed, sportlines, Z06's, w/ no issues. i did a little light hammering on the inner fender just for heck of it, but otherwise no problems. its a good looking setup, check my webpage in the sig for some pics, i think they are on p.2
