As we have gotten the suspension of our C7 together we noticed that although it felt better with better balance and the car was easier to drive at speed, our track lap times did not improve very much. We felt that the stock setup was great with the stock wheels and tires and it shows how well the Chevy Performance factory developed performance suspension parts were calibrated around the stock wheel and tire package. With this in mind, to get further improvements out of our C7 we were going to have to increase the tires size and get stickier tires. To do that we enlisted help from Titan 7 wheels and Toyo Tires for help in getting more speed out of our Vette.
Our new wheel and tire package was selected to put the maximum amount of rubber on the road with the minimum amount of weight. Fortunately our C7 has pretty large wheel wells!
For wheels, we selected the Titan 7 T-S5 wheel. Titan 7 worked with us to help develop a special fitment just for the C7 Corvette. Titan 7 forges their wheels with an industry-leading 10,000 tons of pressure using multi-stage dies. This forging process gives the wheels great grain orientation with excellent strength and mechanical properties. Titan 7 produced a few test wheels with different offsets and we tried a few combinations until we came up with something that would allow us to maximize the room we had, allowing us to stuff a super wide tire in the stock wheelwells.
The Titian 7 wheels are all about smart weight reduction without sacrificing strength. In the wheels mounting pad, you can see that all excess material has been removed and the pad area hollowed out. This is done in the forging process, not by post forging machining to assure good grain flow and strength in this area. Little tricks like these assure that that wheels will be light. The T-S5 has a knurled bead seat area to help prevent the tire from spinning on the rim. The inner rim flanges are also beefy for strength in this critical area. Our front wheel is 18×10.5 with a 52mm offset up from the stock 18×8.5 with a 56mm offset while the rear wheel is an 19×11 with 79mm offset up from the stock 20×10 with a 79mm offset allowing for an aggressive tire fitment with workable tire to fender clearance.
The wheels have some cool details that this machined in Titan 7 logo.
