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.

..I also have a 427 Cobra replica with an aluminum chassis.

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).

Oh now he owns up to it - he's been cutting springs...

...I'd go to www.superturbodiesel.com and see if there are any tips on their forum.

Does this plan look okay?

1981 300CD

1. BBS RS 7 x 16 Nexen N3000 205 50 16 ET 24 Diameter =24.1
2. BBS RS 8 x 16 Nexen N3000 245 45 16 ET 11 staggered set D = 24.6
3. OEM oil pan protector
4. KMAC Camber adjuster rear
5. front 3 inch spring cut = 2 spring Cut
6 rear 3.5 inch spring cut = 2.25 spring cut

Did everything on the list except haven't put on the wheels yet. And cut the back 1.5 coils not 2.25.

do not sit in the seat of scoffers

Psalms 1:2

but whose delight is in the law of the LORD,
and who meditates on his law day and night.
3 That person is like a tree planted by streams of water,
which yields its fruit in season
and whose leaf does not wither—
whatever they do prospers.

Okay you try to import a set of H&R springs into USA... Physically impossible unless you have $600, but then you might as well put it on bags.

Oh, so you cut the coils. That explains everything. When you cut coils off a spring, you increase the spring rate.

Yes, I have overcut the front it seems.

Solution: I am pondering.

New Comforts front
New front LCA bushing.
New 3 nub front shim.

New front springs and recut 1.75 coils front???
New Comforts front.
New front LCA bushing

I can fix this but it is getting expensive. H&R would have been cheaper.

Is there something wrong with leaving the springs stock?

The link works correctly, but they dont have the correct W123 springs.

Most people that lower their W123's are trying to bring them down to a modern ride hieght, like for example a 2011 E550. Our cars stock look like monster trucks, compare to a new Mercedes.
