    My suspension really sucks.

    Okay here is my issue. It sounds kinda stupid, but I feel like my car should t feel this shitty. Here's my front suspension setup.

    318is St Lowering springs.
    E90 drop hats .
    Unknown mileage bilstein sports .(taken from my last e30) , with no cut bumpstops.
    And it's a 325is with an S50 In the front.

    So every time I hit any sort of bump, it's fucking bone jarring . I feel like I have No suspension in the front .the streets around here suck dick, small bumps are OK feeling , large bumps you feel it in the entire unibody of the car and its a big crash . I know my setup is kinda budget, but I feel like it should adsorb more bumps . Here's what I think I may want to do to get my car feeling better .

    1. Replace front shocks with new ones.
    2. Cut bump stops in half .
    3. But a GC coil kit for the front . Or just a better setup in general .

    People running ST springs in the front, are they really just this stiff?

    K thanks r3v.

    I like my ST springs, buy my shocks are also softer than billies.

      How low is your car?

      That accompanied by blown shocks won't help.

        Not really THAT low. Maybe 2 inches in the front?

        Here is a pic, the red Coupe is mine.



        Is cutting the bumpstops really that nessecery when lowering ? I feel like their is little to no suspension travel.

          Lose the drop hats. I had the same issue with m3 st springs, e90 hats, and kyb shocks (325 with m20). It was pretty much on the bump stops. Going back to the stock upper spring seats (and spring pads) gave me just enough travel that I only hit the bump stops with the articulation caused by turning at full lock into steep driveways.
          Now the stance looks good, and the ride is comfortable but confidence inspiring, perfect for a daily driver that sees occasional auto x use.

            You absolutely need to cut to the bump stops on the billies. I had the same problem up front with the same spring, but without drophats and without a heavy s50 upfront. You are probably riding on the bumpstops 24/7 with that weight. I say take out your drophat, cut the bumpstop, and save up for GC.

              This is what I was kinda figuring It was .

              Plan on saving up for a nice setup !

                You can just replace the Bilsteins as they do not have good amount of travel. Just replace them with Koni SA and be done.

                And your inserts might be blown? My buddy Swanny has Bilstein sports and the ST springs and they are amazing with none of the issues you are having.
