I need to add splash guards to my 2015 Corvette stingray. Lots of road rocks where I live. ACS seems to be the best bet.... they have an enhanced splash guard and also an XL splash guard ..... The basic difference is two things: price and wheel coverage. The XL set of four guards is $500...the 4 wheel set of enhanced is around $245....the difference is that the XL goes out about an inch farther from the car body to cover the entire wheel....is it worth it?
