First thing I would check is the exhaust- Specifically, make sure the mounts are still secure, or have a look at the clearance the tie-rod has with the exhaust while the car is on the ground now that the hicas set-up has been modified. Whoever installed it may have messed with the exhaust hangers or something in that area. You've gotta use pry bars 'n shit to do work on that stuff. It's tight in there too, with a decent sized 'zorst.
