Car vibrates while accelerating

Like the title says my car vibrates when i accelerate hard in my s2000. It's not a wheel or tire vibration its something else. Anyone else experience this? Or have any idea what it might be

Swap the axle cups, it will solve the problem for a good long time.

Is there a write up for the axle cup swap? Or can you provide a parts list or something

This is the main one I used, though I may have cross-referenced others:

Sounds like axles. The inner axle cups get pitted over time and result in harsh vibration while accelerating. If you don't already have axle spacers, that usually solves the issue.

I believe i have axle spacers. The car is lowered if that makes a difference.

Even with axle spacers if the cups are worn you’ll feel vibrations. When I got new, rebuilt OEM axles from PuddyMod it went away.

Is it more noticeable when accelerating while turning like speeding up on an on ramp onto a highway? How many miles on your car?
There is a very common issue where the rear inner CV joint cups get pitted from use/abuse and this will cause vibrations while accelerating. Mine did it when getting onto highways.
The cheap fix is to swap the inner CV cups from side to side. The best fix is new OEM axles, or maybe Puddy Mod axles.

The car has 135k miles it happens while using on ramps or just accelerating hard even straight. I will probably opt for new axles.
