to switch is because my fronts are only 8" on my SSR's and i have to run a 14mm spacer to clear the brakes. im just not a fan of spacers, im seeing on track i need to widen my tire pad and widen the front wheel. I found some 17x9" +22 of the same SSR's but the cost was high enough to second guess whether i should get new wheels or not. I just moved from houston, cant say i miss the humidity, but the snow now is a new challenge.
