H&R problem

I live in an area where the roads are quite bouncy and I'm getting a bit tired of the bounce. The ride height is a bit too low at the back too. What is my best course of action (not coilovers) to get over this, thinking of either replacing with eibach springs or getting new dampers.

Opinions??? Are the eibachs higher than the H&Rs

Thanks

If you have only springs and your roads are bouncy than it is not a pleasure to drive.
Eibach has -30 front and -25mm rear.
H&R has average - 35 mm for both.
It depends what springs you have:
H&R Sport Springs lowers 1.5 - 2.0 inches on average
H&R Super Sport Springs lowers 1.75 - 2.3 inches on average

I think that to get rid of the problem (not going into coilovers) you should buy eibach pro system set up. These are springs and shocks.
It will be a little bit higher in the front and higher in the rear.
As to the comfort you will have much much better than on the H&R.

Comfort on the H&R set up is excellent, far better than standard, it's just the bounce that is the problem. Will look into full pro set up

So check what kits they have available for you as sometimes they have strange lowerings.
Sometimes front gets really low while rear is little droped and than coil overs would be only way to go with.

Tighter shocks will help the bounce/rebound issue. Koni has a 10% off sale right now so it's a good time to take advantage on either the FSDs or the Sport adjustables. Hope this helps

When you say bounce, do you mean the ride is very harsh on bumps or are you bouncing up and down like you have blown shocks?

Yeah, FSD and H&R, a well documented combo!

ride comfort is amazing right now, love it. Just when it comes to a bumpy road ( I mean undulating) then me and my passengers are nearly coming out of our seats and I am really worried about bottoming out though it hasn't happenend yet, even 4 up ( heavy 4 up too )

Decided to give the eibachs a try so now considering options.

Keep standard (they have had a good workout with the H&Rs now)
Koni FSD
Bilseins (concerned about too agressive rebound though from link in sticky above)
or
Eibachs

Roads near me are really bouncy and can be slightly rough so looking for best control ride comprimise
