Hi Folks

 

 

My car came with what i believe from an old receipt are a set of Kayaba Gas-a-Just Dampers.

 

They look like them too although the markings have been weathered off.

 

When my car is on even ground, it looks like the rear left of the car is sagging a bit, ive measured and found this wheel is about 20mm closer to the arch than the other 3.

 

also, the ride is harder than i think it used to be, you really feel (and hear) little pot holes and things compared to how it used to be.

 

Do we think a replacement of the rears is in order? if so, what would you recommend for a fast road 1275.

Im assuming, the clue being in the title, these can be adjusted? and thats all might be the problem.

nothing to do with the shocks they do not effect ride height. 

 

look to worn through knuckles. collapsed rubbers failed suspension components.

[timmy850]

Gas-a-just shocks are not user adjustable. If you have hi-los at the rear have a quick look to see if they are on about the same length

[nicklouse]

dont look to the rear look at the front. something wrong on the front has a greater effect than something wrong at the rear.

well theres no issue with the front ride heights or even spacing from the arches, its uniform all round except for the back right shock - the ride definately feels harder on that wheel 

Ive just forked out on a new sub-frame at the rear and turbo clutch, looking at the price of suspension kits ive had a mild heart attack

 

for the record i had this problem before the sub-frame replacement

Its also easy to decieve your eyes if if its not a 100% flat surface. Overhauled the whole suspension because of that..

[tiger99]

I suggest changing ALL 4 knuckle joints first. They are the cheapest parts and also prime suspect. They are often found to be worn right through the cup, which leads to major expense, and possibly worse, if neglected.

[happydude2012]

found out a bit more

Luckily they can be adjusted so were going to have a go later in the week.

 

Turns out the guy who had the car before fitted Gaz a Just upgrades all round and fast road springs from huddersfield spares on the front.

think in the summer when its drier ill replace the whole suspension.

[Cooperman]

To clarify what has been said, you cannot adjust the ride height by adjusting the dampers. The dampers just damp out the springing.

The ride height is controlled by the springs, the trumpets and the knuckle joints.

If the car is low at one point the rubber spring cone or the knuckle joint is the problem. It is nothing to do with the dampers.

Could it be that the OP has these on the front adding to his ride height adjustment confusion?

not had a good look as yet,. just gone off a receipt I had with the car, having a look Friday - could be the case though - ive heard bad things about Huddersfield and also on a lot of other posts people are saying they are only suitable for smooth track applications,

As ive said in early post, the front arch gaps are fine - the back left is fine, there just seems to be a mild drop on driver side rear which doesn't make any sense as I imagine the other arch gaps would be affected if one was sagging slightly. To be fair, its barely noticeable really maybe im being a bit paranoid. But im looking anyway,

 

I do want to make the point, the car handles like its on rails, virtually no bodyroll at all and until I noticed the gap looked a bit lower,. ive had no issues with handling or performance.

[CityEPete]

As Cooperman says the shocks won't effect ride height, the possible reasons are that it has adjustable trumpets (hi-los),could be anything from badly adjusted or even something as daft as an adjustable one fitted one side and not the other, depending then what springs are fitted it could be a rubbish quality spring or a collapsed rubber cone, different age/brand/quality fitted either side.

Probably the most likely is just a worn out knuckle joint.

A few pictures behind the rear wheels will tell us quite a lot.

.

they are not even suitable for track use. they are totally wrong.

then the wings have been fitted incorrectly or the shell is distorted. or the ground is not level.

 

I suspect the latter.

[jaysmini1983]

or the shock is worn out/leaking, also since you have replaced the subframe are you sure you fitted all the rubbers correctly for the shocks especially as you say it sounds louder on bumps etc. or if its adjustable then its set to hard and not returning (i have had this happen on gaz adjustable shocks on the rear as im running springs)
