Default Wheel Hop solutions? IGT/IGT2

I got my IGT tuned in today but have to deal with wheel hop, mostly rear wheels but there is some front hop. Is this common with on-road nitro running rubber tires?

I am running Kronos 20's in the rear and 30's in the front.
60w front / 40w rear both stock springs.
Thickest rear sway bar in softest position, No front sway

Track is very smooth asphalt with sugar water compound....

Car is pretty quick with the exception of losing a lot wheel to ground power.
Screamer in 2nd gear down the stretch.

When does you car hop the most? Turning, accerating, braking? Walk the track....even if its smooth it could have uneven patches that you might not notice from the drivers stand.

Were the Kronos pre-mounted or did you mount them yourself? I ask because the type of inserts you use will affect the bounciness that you may be experiencing. Also, if you mounted them yourself, be sure the rims have an airhole. Some people put them in the tire as well. This helps take some of that bounciness out of rubber tires.

What's the car like without rear swaybar? You might need a softer one or none at all. if you car has lots of traction putting sway bar on will cause the hopping, some people call it tire chatter...which could lead to traction roll. Check it out Its toward the end of video.
