Default Z06/E-ray/GS BC Forged RZ39 Track Wheels - 18"x11", 18"x12.5"

I have 2 sets.

Wide body fitment. Please check below on brake fitment. In short, CCB calipers would not clear withouot shaving, and other brakes need rear e-brake caliper removed:
  • It'd not fit on CCB brakes without modification on calipers.
  • Fits on standard Z06, or Z52 Perf GS (non-CCB) brakes with the rear e-brake calipers removed.
  • Fits on Z51 brakes.
  • Fits on AP Brakes (372 mm / 355 mm Front/Rear), including wider 9668 calipers (which also retain e-brake calipers).
NOTE: They are designed to be track wheels, not necessarily for looks. 18" tires are a lot cheaper than 20"/21" OEMs. They're mechanically perfect, but might have knicks, etc., which should not matter for track use.

BC Forged RZ39
18"x11" ET30 Front,
18"x12.5" ET25 Rear
(22.5 lb front, 23.7 lb rear)
Graphite Gray Color
Comes with Knurled Beads to prevent wheel slip on the tire

Example fitments: 275/285/295/315 /30/18 front, 335/30/18 or 345/35/18 rear tires from various brands. For proper front/rear rotation difference, 295/345 or 315/345 works almost identical to stock, depending on tire brand.

I have 2 sets of these wheels.These come about $5000 including shipping and tax. I can let it go for only $2300 SHIPPED. If you're interested, please let me know.


How they look on the car.



Clearance of front 372mm AP wide calipers that take 25mm pads (9668).


Another look on the car.
