Rear-end wanders at speed Help please

jchammond

Had to go underneath to see what was up myself;already adjusted rear camber to more positive before....looked at ecentric bolts for toe & broke out tape measurer.......1/4" wider track width in front of rear wheels compared to backside......marked bolts and took photos of timing marks....loosened & adjusted equal amounts on both sides(tad more on l/r) ending result was 1/8" narrower in front of rear wheels compared to previous 1/4" wider.......test run up to 130...smooth as glass & don't have to hold steering wheel through acceleration...not sure how much positive toe i have in rear...but Z feels like it's old self again..
