S7 Rear Ride Height

[theduck]

I have a sierra based s7 with separate shocks and springs and noticed today that the near side sits about an inch higher than the offside (gap between tyre and arch) is there a way to adjust the ride height to compensate? Arches appear to be fitted the same height each side so don't think it's that!

its same set up as mine duck only things i would check is the spring is sat in correct place and that the dampers are not soft or leaking.and that the springs are the same size i.e not had one cut down lol was the car on a level surface too as that will affect it

It was in the garage, which I thinks pretty level...

 

Dampers all look new still (cars never been on the road) will check springs are sat correctly. Is there any difference side to side on yours?

[biksz]

never checked to be honest but seems to sit level oh other thing to check which i did not think made a difference but makes alot is the tyre pressures the front of mine was half inch out when measured hight turned out the tyre pressures was a milke out one was 28psi the other was 15psi put 18psi int each tyre and solved it

Don't use the arches as a bench mark

Use the bottom of the car

S7 to S3a had rear arches slightly different out of the moulds

In that case I'll wait until I know pressures are even as I know ones a little flat...

 

Cheers snapper. Could they be as much as an inch different per side?

[Snapperpaul]

Not sure but the floor of the car is more important than the arch gap

I hvent checked from the floor, it was the difference in height from tyre to arch that concerned me / looked odd.

The only measurements that matter are ground to floor-pan. Fronts must be equal, left to right and rears equal. Measure over flat horizontal surface. Some say with equivalent weight of driver in seat or even driver + passenger if that's how the car is usually used. Some say empty. The floor-pan is flat. Rear measure should be 1/2 to 1inch higher than front. (My New 3 target settings are 5.5 and 6 but I have a high sump.) When raising or lowering one corner there is a diagonal opposite effect. Front left raised - rear right will lower slightly. Roll car a yard forward and back after each adjustment to settle the change. Make each measurement with the car on the same spot.

The arch to tyre height depends so much on the build of the car, how symmetrical the parts are, etc that it is no guide to suspension setting.
