If you check out the gallery on conventry's website, there are a couple of cars with the 8.5's mounted up front, an XJR with chrome I believe is one of them...
yeah, I'm a little worried as well with how they will look, but there is so little out there for our cars, without taking a second mortgage, and I finally had it down to the coventrys or the Inovit DTM's, which was even more of chance, style wise, for the LS's lines....the OEM Jag Vulcan's I think are among the nicest, but I waited over a month for wheelsandcaps.com to get them and they never did, and I made a few attempts to get the set from LitoLS, who just completely flaked out on me (no offense, but I think there's something wrong with that dude, really), so the Coventry's were the next best option (and less expensive as well LOL)
The sucky part is that now I've got a staggered set of 18" tires in my garage that I ordered for the Vulcans that I have to sell, grrrr. I didn't realize how hard it was going to be to get the Vulcans, short of ordering direct from Jaguar $$$......
In the end, I think the the clean look of the Coventry, especially in a nice 19" will look really nice...I don't think that the 18's would look as nice though IMO. Well, at least we'll know in a few days how the 19's will look, haha, wish me luck!
