Hello all.

Now the car is on its lowering springs I have a deep concern for the sump, or more precisely how close the bloody thing is to the floor! I work on a farm and have to go over some speed bumps to park in the courtyard. I crept over the speed humps today to try and clear it but could still hear a slight scrape. Got someone to watch and it wasn't the bumper touching the floor, it was the sump. Now i know the Vectra C (well, the ex-plod ones anyway) were fitted with metal plates underneath and a metal sump guard. Can these be purchased for the Omega too? I can't find anything on them or it would it be possible to adapt another one to fit? There's loads of ones from different cars on Ebay.

Cheers.

A sign of shagged shocks if you scrape over speed bumps...  ...unless you've really gone for the chav look on lowering.

They're already here to be replaced. It's on 30mm lowering springs. It seems to 'bounce' a lot when it goes down the other side of the speedbump. This was it parked in the carpark today:

30mm isn't a prob, so would say shagged shocks then

Thought so. That distance to the floor still worries me though!

Mine are Irmscher sprung (30mm drop), no issues.  No shortage of speed bumps around here.

And, as I recall, the sub frame cross members is lower anyway, i think?

you wont hit the sump over a standard "fully across road" style speed hump as sump inline with the wheels, looking on your pic maybe the noise is from your front mudflaps on that yype of hump if its a short 1ft type 5" high...

but you may do if you bridge them "2 in a row or 3" across the road types with 2wheels on the road trying to miss the hump under car...
you may if unlucky hit somthing under engine bay...

ive got a similar issue but i am belting & scraping my cat converters across either styles/type of humps
The 1ft 5" high type across from kerb to kerb
2/3 in a row across road roughly 3ft square 5" high
or the platform speed hump 5ft wide 5"high fully across the road where 1 wheel goes up it drags the sills & front drops off hump before the rear drives up them leaving car stranded on the hump on the brakeover angles you will prob see if you look under car that the 2 cats sit lower than everything else under car & thats whats hitting....?? i take every speed hump at 45degrees so nothing can hit...

well it is the case on mine anyway.. 35mm front 50mm rear on an estate 3.0 with S/L rear shocks

& Theboy before you say ive got a chavvy drop on mine i like the way the omega looks when car is level mate

Errr, well, uhmm, it was like this....   ....I blame Marks DTM

IME, assuming you are not launching cars, its the cats that clout the ground first if shocks tired.
