maybe a dumb question - the oem stuff is interchangeable. is there any clearance issues in the back that might make slight bend differences difficult to accomodate? i havent had a chance to inspect closely.
Hotchkis have released a great kit that is both hollow and adjustable front and rear with published rates for the e9x M3. These options are exactly what i was looking for. I've emailed several suppliers and hotchkis with no response.
