Had the standard contis on mine from new they lasted 10k on the front so tried Michelins they lasted 12k but would like something that lasts a bit longer for £250 each ! Might try Dunlop going by above! 19's by the way!
Yes that's why a tuning box will be best! Just plugs in and out and gives just as much extra power as a chip! Have a look at the comments on previous threads! DTUK are very good and have great customer service!
