It shouldn't take much for a 360 to get into the 12s, & that summit ad is mis-leading, there showing rings/bearings & they don't come with the kit, not that its a bad price as it comes with forged pistons, its still mis-leading, i've already jumped summits azz for having a crappy directory on there sight, maybe i need to jump on them again for mis-leading adds .
