So I picked up some c5 z06 wheels.
18x10.5 rears are 17x9.5 fronts.
The front fit fine, but the rears hit the bump stop when the rear end is jacked up.
So do I buy spacers or adapters? And how big?
Any cons to running these?
Should I only run them in the back or do I need to do both front nd rear?
Any input is greatly appreciated.
Thanks all

When you put on these wheels, jack the rear of the car up by the differential. That way the wheels won't hit the bumpstops.
You have two options for getting them to fit in the wheel wells:
1) Massage the inner fender with a hammer "BFH Mod" (Big ******* Hammer)
2) Buy tiny spacers (1/8") if you don't want to do the BFH.
Most people do a little BFH and call it a day.

Careful on the spacers..make sure you have enough threads showing to properly seat and hold the tire on... i just raised by the differential...
If not your hanging the weight of the rear on the inner barrels..marking them up..

I ran 1/8 spacer and no problem. running 275 40 18 nitto555 if I go 285 i bet it will rub bec of the offset of the wheel. i had the same problem. did the bfg mod to be safe and grinded the bump stop down some.

Be carefull. I had that size on my Trans Am. I had small spacers (1/8th) and it would still rub.
BFH mod will deffinetly help.
Problem isnt when jacking it up because wheels will be even if lifted from diff. Problem is when you drive up a drive way because the differential sways to one side when it travels up and down, which is why it rubs when one side is lifted.
Solutions:
BFH
Spacers (make sure enough threads on studs or get longer studs)
adj panhard bar
get the right offset
**Also, take the tire size into account as actual widths vary between manufactures**
