Stay WELL clear of Eagle F1's
Its well known that they have been known to de laminate (sp)
It happened to a fron tyre on a mates E36 M3 at over 150mph, lucky for him the tyre still stayed inflated.
Several scooby owners have had troubles too and I very much doubt they are the only ones.
New F1 should be a lot better but I wouldn't trust them after that incident.
Those Rainsports or whatever they are called seem to be quite rated by some of the nova guys I know Marc.
