I say soften the front end, see if that helps. at least you can adjust the damping with ease. (if they're adjustable)

Wouldn't lowering the tire pressure reduce the tire's spring rate and increase it's damping?

Woww there thanks for the suggestions!

The present tires are Yokahama Advan048 which should be their best tires for street and strip. I tried with different pressures from 25 to 15psi and the less the pressure the more the bounce.

I will try for sure to soften the front and see what we get. Although I am trying to set at least the engine mountings to harder ones and probably I will go with super pro.

^ As you've discovered, radials aren't designed for that. You have to use pressures that are correct for the tire, or you won't get results.

You can run slicks all the way down to 5 psi. They look like flats, lol. Do that to a radial drag tire and it just won't work well at all. I've tried both, I know.

Parmas, do the simple stuff first. You have several good suggestions on the table to try before actually changing parts. Do those first, and one at a time, or you won't know what change made a difference.

I have no idea. But I do know that low tire pressure causes wheel hop on a radial tire.
