2014-2019 Corvette Grand Sport, Z06, ZR1
Chassis Introduction
The last of the front-engined Corvettes, the C7 generation took a big leap forward both mechanically and fit & finish compared to Corvettes before it. With stunning styling, powerful new engines, and revised suspension geometry, the C7 is a weapon for years to come. This guide specifically caters to the Grand Sport, Z06, and ZR1 models that are commonly referred to as widebody due to their fender differences compared to the base models.

These “dual-duty” fitments are recommended for enthusiasts focused on maximizing performance, whether you use your car primarily on the street, or you’re a weekend warrior driving to the occasional autoX and/or track days.

Hardcore Track / Race Fitments
SM-10 18x11" ET38 w/ 315/30-18 F. // 18x12.5" ET52 w/ 335/30-18 R.
These no-compromise fitments are ideal for hardcore track enthusiasts, time trailers and W2W Club Racers looking to prioritize performance above all else. Additional negative camber is strongly encouraged to maximize performance and tire longevity, and some of the more aggressive fitments will absolutely require it to prevent rubbing under suspension compression. Even with the appropriate amount of negative camber dialed in, some of the more extreme fitments will likely still scrub the liners under suspension compression and/or when turning the steering wheel to full lock. This is par for the course when pushing the limits of wheel and tire fitment. These fitments are not for someone who primarily will use this wheel setup on the street or in inclement weather.
