  • Maybe its me but my suspension feels like..

    I feel every single bump in the road.. I drive an Audi A4 as well and most newer cars don't have this feel. Last I remember all my suspension was kyb components and I think original springs (I drive an SS). What would I be able to do to eliminate this feel.. maybe it's supposed to be this way? Thought i'd ask. I'm also running on tires 205-55-16, maybe this is part of my problem? I'm soon going to be upgrading to 18' with Falken 452's.

    most people look for this, a firm suspensio. the size of the tires doesnt really matter, but the tires themself do. your springs are pretty firm. so to eliminate your "problem" get softer springs and downgrade your suspension. cheap autoparts springs and shocks should do it.

      KYB are junk, so replace them with tokico or bilstein. Taller tires will smooth out the bumps, but too stiff of a sidewall will transmit more bumps, so don't get too small of a sidewall.

          Driving on normal roads its totally fine just if I hit any kind of bump I really feel it. Would the blisteins or tokico's make that much of a difference? Overall it's not that it bothers me that i'm feeling bumps but more like it feels like something is wrong.

            tokico illimunas would help, they are adjustable and at about a #2 setting it feels like a caddy. LOL

              Sell me your springs and buy some non-turbo springs from a local parts store. SS springs were stiffer than normal turbo springs. Shocks help too.

                Nivo, did you get my vm? Wanted to ask you your suggestions for those wheel specs i'll be ordering them from Adriano. Also what pricing he gave you because I know he said they were cheaper because of this forum.

                  yup..

                  This forum's price is $1220.00 with the Falken 452 tires in 18inch.

                  if you lower the car 1" or lower a +35mm offset in the rear works as you won't be rubbing on the fender edge.

                  a +30mm sits nicely and if you have a fender lip roller you can do a +25mm offset on the rear.

                  the fronts will require the +20mm offset.

                  (this is for the wider track suspension)

                    There's nothing wrong with KYB shocks. They are the number 1 ranked shock in Japan, unless you start talking about Tein and Cusco dampers used in the coilover. But for a standalone shock I think they are great. The Z31 has Tokico's on it as stock shocks so I don't see the point in putting them on. I'm running KYB shocks and King 1" lowered springs and yes it's as hard as shit but it also handles. Want a luxury car go buy one, want a car that handles you're going to have to trade ride comfort for handling.

                            I am talking about aftermarket shocks, since hardly anyone goes back with stock nissan shocks. KYB are really cheap, and have too high of a failure rate, to the point where I will not install them on customers cars. The most recent example was a customer that had kyb's installed for three months, and complained of how the car rode. I replaced them with tokico blue's, and they were happy. I imagine that the op is having similar issues.
