m2 springs are lowering springs that i found on ebay on the cheapie..i havent heard of them, and no one posted anything on them. So i was tempted to be the one to try it. I must admit, i am more than happy with the drop in the front, however, i have no clue why the rear only dropped like an inch. The ride is not bumpy at all. I heard kybs were the best, so i said what the heck, and i bought those. as soon as i get get better pics and upload them to a site (someone recommend one please!!) with better resolution, i will.
