    Default What suspension should I buy ?

    I reckon my rear suspension is a bit wallowy (if there is such a word) as a bit of high speed A road driving last night highlighted the fact that it was not very stable at high speed and I had no confidence in the high speed bends at all. So i did the bounce test on it this morning and found that there is considerable bounce on the rear (the fron seems nice and firm though).
    I checked the springs as per a comment in another thread about my car looking like it sagged on the rear, but the springs are near new (black ones) with the stickers still attached, so I've come to the conclusion that that my rear shockers are shot ?

    Is there a good recomendation for good rear shockers to use on a GSi, or are the Vx ones really worth ther money ?

    Irmscher ones maybe ?! ... but that will be x4 since they lower the car and you want the same characteristic all around.

    I don't really want to change the springs as I'd like to keep the standard GSi ride height, but if I have to change all 4 shock absorbers then I will unless I can get away with thechanging just the rear 2.

    Does anyone on here with a standard GSi have an opinion about it's handling as that would tell me whether to buy the original Vx shox or not.

    If you want to keep the standardish ride height by keeping your standard springs, I Personally would opt for the Bilstien damper set up.

    I did this on my Zafira GSi, kept the standard springs but fitted the dampers. I actually changed mine when the car was only 4 months olt so got a good comparison between the two.

    The Bilstien's are a massive improvement over standard, I feel that the Vectra C in general is under damped and these certianly sort it out.

    Some say the ride height can reduce by up to 5mm with the dampers, but I did'nt notice any change on the Zaf GSi.

    Try contacting Courtenay on 01692 404060, although there are no details published yet, they will be part of our trader sceme so if you call them, ask for Jon Sheild (MD) and mention Vectra C.Com.

    VXR Performance centre do not at this time have an uprated damper for standard springs.

    The Vec C, and I think the Signum too, seem to eat rear shocks so not surprised they may have gone on yours.

    I don't think you'd be able to fit just Irmscher dampers as they're meant to accompany lowered springs so I don't think they'd fit on your springs - even though they're a bit lower already being a GSi. I'm not 100% sure about that and stand to be corrected. I just fitted the whole kit - dampers and springs on mine.

    But as TW said, if you are going to go for different dampers - Irmscher, Bilstein etc. you probably want to do all four to get the benefit. Not sure how the car would feel with two premium dampers on the rear and Vx ones on the front. Again, I'm sure somebody will correct me if that isn't right.

    <Duncan reads through his post> Was that actually any use to you or have I left you just as confused?!!

    Edit: Just seen Matts reply - i knew somebody would be along!

    That seems to be the case! My folks changed on their GTS 3.2 this spring.
    They fitted Opel/Vx ones again.

    You will need to change all 4, Irmscher kit is designed to go with there springs.

    Go for the Bilstiens, you will see a major improvement in the drivability and handling of the car.

    Or you could try Koni FSD's... as fitted by Spikey to his Vec... give fantastic handling....



    but personaly, i just swap some more standard VX one's under there..Other more expensive makes don't seem to last any longer... so yer pays yer money...

    So it's not just Saabs that chew the rear shocks then - just anything Veccie based?
