Just mocked up my 18x10.5" oewheels c6 wheels and its looking like i am going to need a spacer and possibly completely cut the bumpstop off. Anyone else have this issue fitting an 18"x10.5 wheel? What wheel spacers should i get? I already have heavy duty longer wheel studs on order. Thanks guys

DO NOT install the wheel with the axle hanging . . .

What offset did you get?

I had56 offset, and the only thing I needed to do was a little bit of wheel well massaging . . .

i cut the bump stops and a little banging but i didnt have to touch the fenders nor need spacers but i am at stock height though.

^^ what Xsta said, I currently have 17x11 TTII's on the back and i did not have to cut/remove anything. They cleared with no BFH, but i did hammer anyways because they were close and didnt want any rubbing while taking hard corners

56mm offset in the rear. with the axle hanging, the wheel does not even come close to fitting. I would have to cut the bumpstop completely off, which i will probably do anyways. Also i am lowered on BMR springs

you shouldn't have to do that. maybe a little bfh at the most

I REPEAT . . . DO NOT INSTALL WHEELS WITH AXLE HANGING . . .

Then they will fit JUST FINE . . . I used to run that exact wheel . . .

maybe my car is weird or something but i had to do the BFH plus cut my bump stops off and run a spacer for my wheels to fit and they are +56 offset and i didnt do it with the axle hanging

just did my 19x10.5 with a 305 tire and will need about 3/4" spacer.

right, but then what happens when i hit a big bump or brake really hard and the rear end lifts up and slashes up my $600 tires? No thanks

Been running 18x10.5 for years on 2 different f-bodies, only had to bfh a little and have never slashed my tires. I'm dropped about 1.25" in the rear and I'm not running a spacer with 295's.

do the wheels hit the bumpstops if you dont jack up by the axle? Is this not concerning to you?

I just did the same thing and actually had the spacers installed but if you jack the car up by the rear axel the tires will go on no problem. No adjustment needed. I had the same concern but once I did this it works just fine. Dont jack the car up by the frame when you install the tires. After you have the wheel on and drop the car, when you do lift the car by the frame the tire will rub the bump stop mount but will not touch the rim. I double checked this just to be sure. I know no one tells you this flat out but I just did the same thing not a week ago. It will be fine because once the car sits down on the springs the bump stop actually rides inside the rim and does not touch anything... you would have to jack the car up in order for the tire to touch the bump stop mount. I did not have to hammer the bump stop either just the bottom edges of the inner fender.

yes i understand this but should i be concerned that if i hit the brakes really hard or hit a highway bump fast enough that the rear end becomes unloaded (same as jacking the car up by the frame), it will slash up my wheels/tires?

i would not be concerned no problems here and i have had 315's on 11' wide rims for many years now.

The rodes in Hawaii are absolutely horrid and I have never had this issue. Running a tire with a sidewall height of 35, I think the bumpstop hits before the tire would hit the fender. I know that I hit the bumstops (you can see slight wear marks on my rearend from it) and, like I said, I've never cut into my tires.

If you don't already have an adj panhard and you're ride is lowered, I'd highly suggest it. I too do not let the rear hang and I've had no problems for years, I just centered the rear.

my c5 DD are doing the same thing.. as long as you dont jack up the body to take the wheels on and off..the bump stop is way in the wheel when the cars on the ground with lowering springs

I didn't have any problems installing my 18x10.5's this way. OE wheels 56mm offset. No spacers either. Close call, but they cleared the bumpstops. I did have to do some BFH though. Hmm..
