The Achilles heel of the C7 Corvette are the Cast Aluminum wheels and Run Flat Tires. The wheels bend and crack with normal highway driving, and this is worsened by the rigid sidewall of the run flat tires. RVRN Forged Wheels are awesome.....I have put over 1000 trouble free miles on them and they run smooth and vibration free. Even after going over road hazards that would have bent the factory wheels. Wish I had done this a lot earlier. Terry rocks! He was a big help during the design process. He kept me up to date during the manufacture. He even got me an expedited shipping discount when production was significantly delayed. The wait was was worth it! Beautiful wheels, strong, resilient and reliable. I couldn't be happier. If you own a C7 Corvette, YOU NEED TO DO THIS! Otherwise you will always be disappointed in the ride and reliability. And don't put the run-flat tires back on either, the ride is awesome with NRF.
