Rear Coil Springs - upgrade to heavy duty?
« on: 23 March 2009, 20:16:08 »
Ongoing saga with my springs............

Since the garage changed my springs last year my car sits 25mm low at the back and consequently 25mm high at the front.

I've just been under and the replacement ones fitted are KYB - albeit they are fitted upside down.  ::)

They've ordered in some more for this Thursday and some heavy duty ones from both KYB.

They were originally ordered from the reg no - should I switch makes or try the heavy duty ones?   :-?

My car has a reg that was on my former 2.0 GLS - could it be it's picked up the wrong details?  Are the springs that different?

I'd make sure they were ordered for the correct type of car rather than reg number. I used online sites trying to determine the correct speed rating of tyres for my Astra shed, I got as many different answers as sites I tried.  :-?  :y

The garage bloke has always been spot on and only uses KYB, Boge or the like  -  ie no cheap crap.

He's checking the order from last year and will try the new spring against the old one for height before refitting - hopefully the standard one will be 25mm higher - cos then I'm not paying his parts or labour bill.  >:(

So far the wrong set up has snapped 3 mudflaps and worn out the rear tyres 6-7k early.

Will the ride be any harsher with heavy duty or does it just mean I can bung more in the boot?

AFAIK the springs do sod all for the actual ride, thats handled by the shocks.

Do you really need heavy duty? Only plod use them cause they constantly haul heavy loads. (fat chavs  ;D)

I fitted these to my estate .The ride height is actually the same as the originals and surprisingly the ride is not any harsher just stiffer.
The ride height  is is controlled by the spring not the shock absorber.

It can also be adjusted by different shocks, otherwise there would be no ne for self leveling suspension.

No Tunnie, I don't need heavy duty - just some that have the right ride height - Tony at WIM thinks they may have the wrong compression ratio

What was the KYB part number of the items fitted......they could be the wrong ones (i.e. self leveling ones perhaps)

The garage asked that today too  ::)

The number has rusted away but has a 7 at the start and that's all I can see  :-[

He also says despite having TOP marked on them they often wont go in that way, so that's why they are upside down  :-/

He's going to take one out tomorrow and compare it to the new KYB & BOGE ones and we'll go from there  :-X
