Re: ANYONE tried the Bf goodrich KDW\'s (including rears) yet?
Not on a Viper, but I do run the BFG KDW2's in 275/40/18 on the back of a 430RWHP Firebird Formula and they are "okay". The only thing I don't like about them is that they are SILENT all the time, no way to tell when they are about to break traction other than feeling the car. This is fine 99% of the time, but every now and again it can suprise you on a high speed corner. I have had them on for appx. 7k miles and with my driving style, a few burnouts and 3 track runs, they might have 5k more in 'em.
