Ever since the coil overs have went on the car is super highly unstable at high speed , highlighting the fact its maybe time for a full corner-weight and geo set up!

before that could happen got some camber and toe arms ordered

not the cheapest by far ! but they are pillow bearing (rose jointed) and are beefy items which is exactly what i wanted and will allow the back end to get set up just the way i want it !
