Hello,

I have an n54 with rbs, around 430 hp (no dyno) just got new tires (255s) and noticed my front wheel hop issue has gotten considerably worse. Xdelete running sport mode (a little less power to the front wheels) still has same issue.

I have subframe bushings+diff bushings in the back. Keeps it locked in well. Any mods to keep the front locked down?

I hear of stiffer control arm bushings, twisted tunings t-case brace... some saying suspension layout is the cause? I have stock everything in the front, i own lowering springs but they havnt been put in yet (need to roll a little).

Most of the issue is when flooring it a lower speeds(under 25km/hr). Any ideas?

I have never heard of front end wheel hop on a xi.
Is it just a hopping feeling ? Or are the front tires actually losing traction and bouncing ? (like launching an old Honda)

FYI I'd stay away from the twisted tuning transfer case bushing. From everything I have seen, it adds so much harshness/noise/vibration that it is not worth it.

Yeah, ive had a friend watch as it happens. They lift and spin a little. It only happens when i floor it and the front end lifts a little.
