| I was running BT12ss on my 998 & now have Diablo's (Corsa) fitted
The Corsa's have a much more neutral feel giving more confidance , where as the 12's seem a bit more aggresive , if that makes any sense
Although i must say the grip from either is Far more than i will ever need
The Corsa's were £200 fitted , if i could get the 12's for say £170 fittted ( Busters+fitting) then i would go for the 12'S |
