san408 18 Report post Posted November 30, 2022 I just bought 15x10 rear wheels with 275/60 drag radials. The car has a 1" lowering block in the pictures, so that's probably going to have to come out to gain some clearance. Stock 9" rearend and caltracs. (Not installed yet.) The fronts are skinnies. 2 SM69Mach and RPM reacted to this Quote Share this post Link to post Share on other sites
RPM 1,190 Report post Posted November 30, 2022 What is the backspace on this wheels? Pics look like you could've gone deeper. Quote Share this post Link to post Share on other sites
san408 18 Report post Posted December 1, 2022 They are 5.5” backspace. Probably could have gone with 6” and used a spacer to get it a little more right on, but I don’t think they make these in 6” backspace. 1 RPM reacted to this Quote Share this post Link to post Share on other sites
