With my camber set at -1.75 in the front I need to run a small spacer with the Drag Radials which are over 11 inchs wide. Im going to go to LSJ brakes for the drags and run 15x8 wheels and regular slicks

It's very weird that he rubs on stock size tires and rims. I wonder why.

do you need to run wheel spacers when you have the 17x9 rim with +38 offset? i was told 9" with +38 offset wouldnt work on my car....

I run floating rotors now same diameter, but 2 mm thicker and a better material, more expensive thick cheek racing rotor.

If you want to run wheels without spacers you need to have about 38mm offset but it is also dependent on the design of the wheel spokes, you can have the correct offset but not enough clearance for calipers due to spoke design.

Most if the newer Enkei wheels will work fine. Older wheels like the RF series Emkei maybe a struggle to clear Brembos. New Buick Regal GS calipers are bigger still and will be a challenge to fit in most wheels. Enkei PF01 are good for practically any Caliper set up, but you need 5 x 114.3 to get the range of offsets and widths you need, 5 x 114.3 is a more popular pcd/more cars/more potential sales. Mustang is 5 x 114.3 for example
Yea, I love 5x114.3. Its the pattern I had on my DSM, I could get wheels anywhere.

I was looking at a 255/40/17 and it appears that its 3/4" wider than my current tires and 1cm shorter. The rims I want have a +40mm offset so I will need a spacer?

A 245/40/17 may be a better idea... lol

who else makes brake kits for the cobalt? I would like Brembos but I dont want to increase my brake size since Im running 15/16 rims for drag racing, I know Baer makes a kit, does wilwood or anyone else?

It seems with those spacers that the hub centric spacer appears to key off the studs not the center of the wheel bearing.

PF01 +35 and 9.5 fits a redline no problem
here is the part number.

the spacer is perfectly centered. the diameter for the holes for the studs is more than necessary to clear as you can tell. and the spacer can be rotated but there is no up/down/left/right play. and once the wheel is mounted you can run your fingers along and feel where everything is mated up and flush.

well after a bit of talking with Powell, found what should be a perfect setup. Going to be ordering some 5mm spacers and the rims/tires Im looking at, should be super nice.

Thanks John

So when I order my rims, since they are custom and I can choose between +16 and +50 offset, How should I order them? Considering that I will get 18x8.5 or 18x9 to run 255/35? Is +50mm too much? I'm looking to have the wheels as flush as possible with the fenders.

so that the 255's dont hit the strutt on the inside id get +30mm if your gonna get 18x9's. and if your getting 18x8.5 id get like a +35mm offset.

No I didnt need one and I am on D2 coilovers in the front and D2 shocks in the back with Eibach lowering springs. Need them for the Drag Radials though because of the 1.75 neg. camber
