Look at Carlyle racing. They have some setups for ZL1s.

I'm doing same. I have buddy who owns engine speed shop and does a bunch of drag racing with higher hp vehicles than we have. Advice is we don't NEED bead lock rims. Obviously, if one wants them, different story. I have about +150 HP over stock on my '18ZL1 too, so i have been asking the question.
I'm only going to drag a few times a year, so just looking at rears. I'm going with Forgestars (there's a vendor on here selling at good price) 17 x 11. Going with the MT ET Street R 305/45/17. Goal here is to keep close to stock diameter so no stabilitrak codes. I'm going with the 17" setup to allow a little more sidewall flex than an '18 or 20" rim. I hear the 15" version requires a caliper change. Not for me... THis 17" rim is supposed to clear our brembos.

A high pad clearance 17 will fit the rear and a high pad clearance 18 will fit the front with no brake changes. I know the 17 Racestar rears barely fit over the calipers and have heard the 18s are the same on the front.

I guess it depends how hardcore you want to go. I have a set of 17”x10.5” Race Stars with 305/45/17 ET Street Rs, and they work and fit very well. I also got a matching set of 18”x5” for the front, but haven’t mounted them yet.

This is prolly a stupid question, this setup will also fit a ZL1 1LE right?

I don’t see any reason why it wouldn’t. Ride height is the only thing I could see being an issue, since they are taller than stock. At stock ride height, I’d think it would be just fine.

Same exact setup here with skinny's up front.
