    Default What Shocks for lowered SRi

    I have an 03 2.2dti SRi and have had it lowered with Koni 30mm springs and the standard vauxhall shocks for the last 2 years. Drives and handles great but now the drivers side front shock is knackered.

    What shocks do I now put on as I would like to further improve but don't want to spent a fortune. Do I go for shortened or stay the standard length?

    Hi,

    You'll need shock absorbers made fro your lowered springs, ot you'll kill them too.

    The B4 are said too soft for the SRI : they're basicall better quality stock-equivalent ones.

    The B6, or in your case, the B8 should fit better.

    Monroe should aslo make stock equivalents, but I dind't investigate if they make sports lowering ones. Kyb should only make stock OEM equivalent too.

    Koni also have two fittings for the vecciy : either the FSD (that will suit original springs), or the Sport series for the lowered ones.



    I'm actually considering changing the shocks, but not the springs, as the GTS (Opel equival to the SRi) is almost too low already. It's "only" 20 mm lower than the classical sedan, but with an Irmscher front spoiler, you're in trouble already (BTW, the original rubber spoiler fell down too).

    When you're talking about 30 mm lowering, is it as compared to the standard Vectra C, or compared to the already lowered GSi/SRi ?

    I always wondered how this was achieved, provided the lowering springs are mostly made to fit the car's weight accordinng to its engine...

    I personnally would probably go for Bilstein B6 with the original low springs, but still need some advice.

    Honestly, the GTS/SRi, is much lower than just 1.5 mm. Or my springs got packed with time, but all the shocks have been changed (to new OEM) in the past years ; the front ones are only 2 years old, for instance.

    If I get any lower, I'll scrape everywhere. Not an option for me.

    Seriously, would you get any lower than OEM ? We don't have German Autobahns, here !







    The next one (my avatar) was taken from my home.

    If I entered from the top of the street (to your left on the picture), I would literally plant the front spoiler into the ground because of the ramp's (so slight, though) angle, no joking.

    I an only enter from the lower side of the street, and I get out backing and turning upwards (it's a dead end to your left anyway).

    And the entrance is almost the same level as the street...

    Only 1/2 cm lower would just kill the bumper. I couldn't even go through the humps we have here (I can't climb some of them straight ahead already).



    I've measured about 35 mm between the top of the tires and the summit of the wheel arches, both front and rear.

    The 235/35/19 tires are exactly the same diameter as the original 215/50/17, the actual difference being only 1,6 mm.

    What about yours ?
