why dont you go waiheng
wasting time here sourcing for a 2nd unit
some more
you also need to go exhaust house to fix the piping if you buy the 2nd unit
no difference maybe worse
better make a new set
it will help you ease your neck of pain
Would like to ask what are the values you are using on the alignment of your car? Currently i am running slight all toe in all 4 wheels around (tuned by the tire guy), camber and castor untouched at all...
