Default 15" Drag Wheel Set Up

Is anyone running these wheels from Jegs? https://www.jegs.com/i/JEGS/555/66178/10002/-1

Also what is the backspacing/offset your are getting away with on your drag setup? The ones I am looking at are 15x8 with 5.5 inch back spacing and 27mm offset. Also are there any GM OEM 15inch wheels that work on C4s well as drag wheels?

15x8 27mm offset with a 255/50r15 tire will poke about 10mm wider than the 17x9.5-57 late c4 stock wheel.

Will the 15" fit over your brakes? Just a question, why not the 10" wide?

Derad, I have the SUMMIT Drag Thrust wheels on my C4 front and back. I have the 561-5461P on the front along with a skinny drag Hoosier the tire set's flush with the outer edge of the fender well. I have the same wheel style on the rear in an 8", they fit very well regarding offset, look. The only issue you will have is with the brake caliper. I had to grind off the fin's about a 1/4 - 3/8 of an inch to great proper clearance.
