For C6 Z06 drivers that drive on the street and the track, rear 18" lightweight wheel availability has been limited until now. O.Z. Racing has introduced an 18x12 57mm offset Alleggerita HLT that's ideal for track use.
The anthracite painted (pictured above) and black painted finishes are currently available, while other painted finishes can be special ordered for delivery in approximately 60 days include blue, gold, orange, red and white.
Since the C6 Z06 typically comes with 18" front and 19" rear Original Equipment sizes, it's not possible to display the 18" wheels on our Upgrade Garage, so contact a sales specialist for assistance.
Combined with the 18x10 40mm offset front size ($399* Anthracite, $414* Black and $429* other finishes) you can run the following custom fit track fitments of 345/35-18 Hoosier R6 or A6 in the rear and either 295/30-18 or 315/30-18 in the front. These custom fit track fitments are aggressive fitments where the edge of the tire will be further out towards the fender. Suspension modification may be required to clear the fender lips.
This 18" combination weighs 3.8 lbs. less per rear wheel compared to the 345/30-19 Hoosier R6 on 19x12" O.Z. Racing Ultraleggera HLTs. 3.8 lbs. Less rotational weight will significantly improve braking and accelerating at the track. Read "Road Wheel Weights Can Affect Your Vehicle's Show...and Go" to see how lighter wheels can affect a vehicle's ability to accelerate, brake and corner.
Keep in mind that the above tire sizes are custom fit options, so whether or not you rub depends on a number of factors:
1) Suspension modifications and/or suspension wear
2) Alignment, specifically camber setting
