Spring of 2017, like an idiot, I installed the rear nitto 285-40-18 (NT-555's) reversed. 555's are directional tires...and marked... 'left side'....'right side'. It would pull violently to the left....at the top of 2nd. Almost put it into the hwy concrete center divider...twice.... in the dry, warm summer late afternoon. Fall of 2011, after the roush suspension + blower installed...(and rears mounted correctly), get into the gas..and it would pull violently to the left..... but only on wet pavement. That's dangerous around town. Without lca re-locate brackets at the time, and rear lowered 1.25", the oem lca's were higher at axle end. Get into the gas pedal, and you are taking weight off the rear axle. So in went the BMR lca's / uca / re-locate brackets / PHB. Used top holes on re-locate brackets. 18 months later, dropped down to middle holes. Still later, in went the tru-trac + watts link. Traction control off in the dry, and on..in the wet. I'll try traction control 'on' in the dry...and see what happens.
