Well if you have no luck i have a full set of BRAND NEW Irmscher springs for the V6 saloon that i will be selling on in the very near futureThanks for that - could be a useful Plan 'A'. If I have problems can revert to the diff lowering approach.
Have been underneath this eve. to have another look and applied a little penetrating oil in appropriate places to help things along.
Biggest hassle has been identifying the best replacement option following the stunning £361 inc. quote from Vauxhall - that is a pair! Fitting would be a further £100.
In the end, suspect I will take the advice from various forums and go with KYB springs from http://www.buypartsby.co.uk/ as it is clearly a minefield between normal, heavy duty, constant thickness and progressive (as per OEM) and phone call to Buypartsby helped no-end. In my case, KYB's own website lookup returns RX5414 as the correct spring but if you go to the trouble of downloading the PDF catalog it propses the RJ5414 - as recommended by Buypartsby. No doubt the RX would fit, but the RJ is supposed to be a progressive design and a better match to the OEM part.
change your towbar would be the best way to go,the underhanging towbars are crap,there was a case where someone with a carlton ripped the rear part of his car away because of these towbars,he was towing a caravan and went over a raised manhole where the road was being serfaced,the original towbar is hidden out of the way under the rear bumper,all new towbars for cars after a certain year have to be styled like the oe barHi
I've a P Reg Omega 2.0 GLS Auto and fitted a cheap tow bar last year (cheap in that the tow bar hangs under the petrol tank and on some of the speed bumps around our area it scraps along the top of the bumps when I have passengers in the back.
The car has not towed anything other than my little trailer but I'm looking to buying a caravan this year.
Question. Is there an easy and cheap way to beef up the rear suspension and to raise the ride height of the back of the car? It's not fitted with air suspension and I just wondered if I could raise the height without breaking the bank.
