just thought I'd share my suspension upgrade experiences.\n\n1995 940 2.3 SE Turbo estate\n\nI needed to replace the front shocks and top bushes as one had popped\nout hitting the bonnet. I already had Bilstein sport shocks in the\nback and Ventura standard springs for a saloon (resulting in a\nuppointing front, a mistake from ECP).\n\nAfter 2 failed attempts to deliver the top bushes by ECP (aftermarket\nparts) with bearings or in a decent quality they eventually delivered\nthe correct parts. On the other hand Europerformance provided the\nexpensive front Bilsteins and all round Cobra springs (progressive,\nuprated and lowered by 40mm) quickly and efficiently. I would recommend\nthem but noticed their T&C seems to infringe the Sale of Goods act,\nsaying that all warranties are with the manufacturer (a common web\ncompany problem these days).\n\nThe Bilsteins are impressive units with the shaft about 95% the width of\nthe outer body, and very stiff.\n\nThe replacement work was straight forward. On the fronts I used a pry\nbar/jemmy to seperate the bottom ball joint and plumbers shifters to\nundo the shock retainging bolt and do up the new one. Otherwise very\nsimilar to 340/360 shock replacement. The rears the main difficulty was\ngetting the jacking points onto axle stands as you are lowering the\nsuspension while trying to lower the car onto the axle stands. The car\ntends to move on the front wheels (maybe some wheel chocks would help\nnext time), and the axle stands tend to tip over as the weight transfers\nonto them. The rear spring retaining bolt was difficult as usual\nneeding a deep socket and the stud tends to come out as the end and bolt\nare rusted together.\n\nnow the performance;\nThe new springs and shocks are impressive for fast driving, this is now\none of the tightest cars I have ever driven, and it really takes the\ncorners. I havn't been brave enough to really try the limits yet, needs\nreturn of the GY F1 to the rear, which is under respray for\ncorrosion/leakage the Pirelli on it now from the spare is not as good.\nHaving said that I have over commited on speed once and been badly\npositioned on the road comming up to a corner and met another car\nsuddenly, the car now responds immediately to swerves and corrections\nwithout large tail slides.\n\nThe down side is the car is definately not a practical load carrier now\n(unless the load is not fragile), and loaded up with people does scrape\nthe mud flaps occasionally. It doesn't look too low, still a reasonable\nclearance, but the progressive bit of the springs is very short,\nespecially at the rear. On dropping the car to the ground the rear\nsprings are binding at the bottom (but this maybe a design intention).\nRamps are not too bad on the entrance, but comming out it really seems\nto crash onto the road. Previously the car was under damped and under\nsprung, but now overly so, much more than my partners 323i which I\ncalled a go-kart when she got it. I would have loved this in my 20s,\nbut that was some time ago.\n\nI'm thinking a more inbetween spring on rating and lowering might be a\nmore reasonable compromise, anyone tried any other sports springs.
