In this video Eight16 Garage on YouTube gives is full review and opinion on whether you should lower your C8 Corvette and his review of the Paragon Performance Lowering Springs.
At first he didn’t like it lowered especially in the front but he made some adjustments with no issues of rubbing or hitting the pavement.
The fender doesn’t come down and hit the tire and the ride quality is the same as stock maybe a little firmer based on his ride height settings.
Also the fender wheel gap look really even and fill the wheel gap from stock a lot better making the C8 Corvette look a lot better.
