I was thinking around 5-6 too, but it's been so long since I've noticed a set for sale, that I have no idea...
And, no I would still love a set of the FR500s, but I'm not sure what I'm gonna do with my MK... after the body work fiasco, it'll be another grand just to have the car re-wet sanded, and thats only assuming that they don't rub through the paint, otherwise I'm looking at around $10K to make the car right...
I've been thinking it would be easier to just try and find another pearl red over grey and try to start again...
