Hey folks,
I have a set of Wet Okole covers on my Jeep seats (where they really get put to the test). They do protect well, and the fit is very good...
...One word of caution, though: Since these things are neoprene (sp), they're rather thick, and so they WILL change the feel of seat. In my Jeep, they make the seats feel like there's less "bucket" to them, and I can't imagine that that's a good thing in a Corvette.
Again, the QUALITY of these covers is vey good, and they ARE comfortable. There's just no way I'd put them on a performance car, as they reduce the depth of the seating surface (which we all know aren't that deep to begin with on the Z's).
