Unhappy rx7 goes bump bump down the road

Took my rx7 out for a little ride today for the first time after the build. It was in town so I only was going around 60kmh. But my car seemed to have a limp. It was a nice smooth motion. I'm worried that it is the fly wheel after learning there is a different counter weight for s4 and s5 and the dealership only had one part # for the weight. So not sure if I got the right one. Also I don't have any weights on my drive line. Got it used and didn't have any. It seems to me that either of those would cause more of a vibration since the are rotating so fast. Maybe at higher speeds. Any thoughts. Oh yes there are only two bolts holding the differential in right now. Don't know whether or not that would cause it.

Anything? Would you be able to feel something if it is the fly wheel when reving in nuetral. Any good ways to eliminate any potential cause.

Yes, you would be able to feel anything wrong with the flywheel in neutral.

Alright that is a load off, that was the one thing I didn't want to deal with again. That fly wheel nut takes super powers.

I had an impact wrench, and we still had to heat it up with a torch before that thing broke loose.
