well I have done this to my car and it has been stuck at the bodyshop since- 2.5 years to be exact BRP says there isnt a bump steer problem .......
on a different note the year one 69 r/s convertible car - looks like the pace car had it done but this year on HR Power tour the car has adifferent subframe under it - never had a chance to talk to anyone at year one about this- makes you wonder though.....
