I had weled my stock rear end spider gears up in hopes of producing a "Locked" rear end. now I have bits and pieces and no useable rear end.... Well since this is a pure AutoX car then I'm looking at getting a LSD rear. I like the feel of a locked rear. it drastically helps. The two wheels pulling dropped lap times today untill it blew on launch producing lots of pieces ;) What percentage LSD should I get? and does anyone have one forsale? I need one pronto. Thanks
