2010 white diamond sedan, 6MT,all options. 641 RWHP/592 RWTQ
I was just wondering if those of you with around 550+ RWHP have big traction problems with the stock Michelin's? I am debating getting a 9.5 lower and a tune but don't want to if there is no traction at that HP level. Also I don't really want to switch the tires. Thanks, oh and I have a manual.
