Default Surprise fitment: C5 z06 SQUARE 18x12.5 stock suspension

Car setup: stock C5 z06.
1) Fender mods: I just moved the front fender liners from the inside, to the outside of the fender (~1cm extra diameter of fender space). Instead of screw, Liner, Fender; it is screw Fender, Liner.
2) Suspension settings:
Camber F -2.2 to -2.5 (stock bolts limited)
Camber R -1.6-1.8
Toe: 0 front, 0.1 out rear
Caster: hmmm lost data
3) Wheels/tires: 18x12.5 +36ET Trackspec SC5R’s with Michelin S8 slicks 300/650/18 (about 305/35/18 street tire sizes – without doing the math).

Outside of parking (hard turns), no rubbing on z06 brake ducts, under hard compression and tight turns. Overfenders are removable and magnetic, no clearance increase – basically cosmetic and to keep rock damage down. I don't have the pics- but front tires stuck out 0.75 to 1 inch static.

I have been running 18x12.5 Apex wheels with stock fenders since 2022. I didnt have to modify any inner fender or outer fender to make them fit. I do have rack limiters so the inner barrel doesnt rub at full lock, but I never need to turn that much anyway.

Nice- are those 52 offset? What size tires? It looks like you have quite a bit more front camber than I do.

Yes 52mm offset. 315 tires square and just over -3.0° front camber.
