I'm planning a 5-lug conversion of my 2006 CTS-V, using a C6 hub and keeping the stock calipers. Can anyone tell me if the Forgestar CF5's will fit after the conversion? I've read that a lot of wheels don't have enough clearance for the calipers.

take some measurements and call forgestar. find out what offset you'll need on the front to keep the calipers out of the spokes.

I did. Just eyeballed it with a straight edge, tape measure, and vernier caliper, so they're not exact, but should be close enough for government work.

i just found them. i've seen them in the past so i knew they existed.

i'll probably have to track them down again once i start looking for wheels next spring when i do my 5 lug swap.

i would make sure you get the wheel offset correct. I had too much positive offset that i had to use spacers to help the wheels fit. The front spindle and rear tub were my issues. Never had a caliper issue except on my Tahoe where i had front and rear 380mm rotors with 6-piston front and 4 piston rear calipers. Needed a 20mm front spacer and custom studs for that project.

Zr1 wheels you will need a 8mm front spacer to correct the offset and a 25mm rear spacer to bring the wheel out properly...
