Drunken,
I originally tried the A048's and I found them to be a pretty average tyre. Basically after the first couple of heat cycles they got quite oily almost and the rubber stiffened right up which made them very hard to get heat into them.
The only advantage was it meant the tyres lastest longer but they were a good couple of sec's slower around the track than RE55's.
I know a number of the WRX Club guys are using the Toyo's however. But I still think RE55's are the way to go for the ultimate street tyre. Robo - you need to come to the track again dude!
