(G) Hgt lowering suspention

Hi guys and girls last week i was looking around for some standard shocks and spring for my Hgt 155. I stumbled across a Hgt with Bielstien Lowering suspention. i have had it on my car for a few days now don't get me wrong the ride height is fantastic looks realy great being lowered i think it is by 40mm . The only problem is is when i go over speed bumps even realy slow the back end feels like the shocks and springs is just one big block of rubber and realy sends a shock through your spine the front is fine. Does anyone know if there is anything i could do to stop this. Thanks

I have a bilstein shocks and spring kit on my hgt and I think that is somethin you have to sacrifice for great looks and performance but it could be a bit softer in my opinion

Hi yeah derfinatly needs to be softer. i was talking to someone last night who said that with shorter springs going on the rear that i should of taken off the rubber thingy that goes in the middle of the spring because the it will be that that is hitting and not the spring doing it's job.
