Wheel hop again
I took the Vette out today after fixing the throttle, blades not opening fuly and a jet change. Went up two sizes in each. I want to tell you it made a big difference. My problem is every time the tires break loose, which is when I roll into the throttle in 1st or 2nd and the tach climbs real fast the rear tires start to hop a LOT. If in 1st it gets violent 2nd is just about as bad. I get out of it in 2nd and it stops but as soon as I get back into it and the tires start to break loose it just starts hopping. I did get one good shift into 2nd and just let it rip and just let the tires go but after about 2 seconds it just got so bad I had to let out. This was on the street on cold pavement so there was not to much traction. Last time I went to the track I had the same thing. I have a 420# spring, used to have a 330# and it did the same thing. Bilsteins on all four corners. I don't mind the tires spinning just want the hopping to stop. It just overpowers the rear tires. 
The only bushing that is not urethane is the front of the trailing arms.
I will say the throttle and jet change and cool weather made some more power which is a good thing.

Does it wheel hop on a smooth surface ? Mine hops if there is uneven pavement and it doesn't have to be that bad, but is fine on a smooth paved surface.

I've driven many Porsche 911's.. Those cars NEVER want to let the tires rip. Terrible hop as soon as it lets go. I always attributed that to having all the weight on top of the rear axle.
My vette has never done this, but am very curious as to what else will cause wheel hop.

I installed both the locator kit and the lift bar at the same time so I'm not sure if one had more impact on eliminating wheel hop. The heim jointed rod in the picture above won't reduce ground clearance to the extent of the SSM piece.

I made the aluminum discs myself. Not to hard just cut slices off and aluminum bar and drilled holes. I do have the urethane bushing in the front of the diff but was considering going to the aluminum disc to further tighten things up.
The SSM bar looks like it does not bolt up but has a snubber cushion. Is this just for pictures or does it bolt up. Do you guys think a Heim jointed bar is as good as the SSM or similar bar. It looks easier and looks like more ground and surronding clearance with the bar. I can certainly fabricate the mount at the spring and the frame.

Check your driver side motor mount, it may have separated causing what you think is wheel hop. I race mine once a year at Vette Magic which is a Corvette's only race day. I thought they had really perpared the track that day as my street tires experienced what I thought was wheel hop, turns out that my motor mount had broken and the safty catches were the only thing keeping the engine in place.
Good luck
