the travel seems too short and

both jounce and rebound is to quick in relation to the jounce and rebound of the rear.

I think I know what you mean. Going over speed bumps the front of mine seems to take the bump more harshly than the rear, especially when the cargo area is loaded.

Probably too high of a damping rate going both ways. Lose the HD's. You're about to have a PM.

I bet something is worn out on your car. I would renew everything and see what I have.

The stock suspension is pretty soft on these cars. If it feels harsh something is amiss.

Yes, that is right.

Good News: 1. My off ramp off the freeway has a lengthy hard sweeper curve for a 300 yards followed by a 90 degree turn onto the main artery which has no traffic because developer went bkrupt. I can go 55 mph on that sweeper with very little roll, like 1/2 inch drop left to right. Then I can take the 90 degree turn at 45 mph with the same. The handling is 7x time better.

2. Also the car looks great; looks more modern as there is zero wheel gap in the front and the body covers 2 inches of tire in the rear.

3. Also had the same too fast jounce rebound problem in the rear, and i went to comforts from HDs and fixed it; the car has the wallow back in the rear.

4. I went to 3 nub shims from 1 nub shim in the rear to get the proper rake.

5. The car has urethane rear lca bushing which is the kmac accentric camber corrector inside the bushing and the travel increase from the mushroomed oem bushing that was uber difficult to remove so i am concluding there was friction stopping the travel. The hds were already in when i put in the bushings and the travel increased, got looser, on the bounce test.

Bad news.

1. I over cut the front. 2 coils front, 1.5 rear.

2. I am cutting the front tires on driveways

3. The initial hit on bumps is too hard and jounce and rebound does not match the rear (faster).
