Hi

I bought a 1988 CQ a few months ago, when I bought it the rear end was sagging so I replaced the suspension for new Lesj÷fors coil springs and new KYB shocks (all of which was sold as suitable for the CQ), this has helped but the back end is still too low by about 1-2'' from the original ride height, meaning the rear wheel arch is level with the top of the rear tyre. I have also replaced the wishbone bushes and lower ball joints.

Is there anything else that could be changed to raise the ride height back to original? Would replacing the top strut mount make any difference? (I think the current ones are original). Should there be a spacer on the coil spring to raise it?

Thanks for any suggestions.

That's not right.

Ride height is a result of shock length and spring load.

If the springs are too soft, it will sit low
If the shocks are too short it will sit low.

it's a 1988 - one of the very last of the B2 cars ?

If so, it's possible you've been sold bits for a B3

Mike,

Thanks for the suggestions. Yes the car is one of the last B2's. I replaced a rear wheel bearing soon after I bought it and that took a little tracking down as it was a slightly unusual spec compared to earlier versions. Perhaps the strut housing is longer than usual.

I am fairly confident that the springs are correct, but I might look into the length of the shocks when fully extended. You wouldn't happen to know what the correct length would be for the original spec or where to find that info?

Thanks again

Just done some checking

Interesting thing is that the rear shocks for the Cq are 893 513 031 G which is a B3 part number so I think we can rule the shocks out as being a problem.

When I had mine the rear always sat slightly lower than the front, even after fitting new shocks and springs all round

I'm looking into the shock length, from what I can find online the KYB 666002's that are fitted seem 6-10cm shorter than the KYB 366006 listed as the OEM replacement (using the part number you give above). This might be where the problem lies!

Will keep you posted.

6-10cm is a lot.

More than a 2" drop.

Did you choose the shocks or were you told those were the right ones ?

Rear suspension now sorted! It was the springs after all. I got a new set of road springs from Pete Reeve, Quattro Corner, and fitted them on the driveway. The old CQ now looks the part again!

Cheers
