So im having a vibration issue directly after I put in a UPR tubular k with tubular control arms, coilover, cc plates whole 9 yards. K member is relatively quiet and rides nice other then a harsh vibration after about 80-85 mph. Im wondering what it could be. Usually I dont post a question like this but in this case im all googled out. Im thinking its possibly an issue with my pinion angle now, but I dont see to many posts with tubular k member and pinion angle problems. Car has same vibration no matter were my coilovers are set at. Front tires are 2 months old and balanced, (not the problem) & the vehicle was just aligned. No problems there either. I am running the OE front struts not that I believe that would cause the problem. This is just temporary for time being and there in good shape. Car has under 60k on the clock. Any ideas??? I can do most of the work on that car myself, but when it comes to pinion angle and how to adjust or check im clueless.
