This is for a Genesis Coupe on Stance Coilovers with Swift springs. The heights all seem reasonable but the driver side is almost a full cm lower, I wouldn't expect the driver side to be lower
I just need to get a gut check to make sure the shop didn't mess up anything. Car drives and handles fine.
FD FP 655mm 664mm (-9 mm Difference)
RD RP 682mm 683mm (-1 mm Difference)
I'm not sure but it doesn't look right to me.
It looks like they didn't adjust diagonally.
What do the scales say? What is the crossweight %?
50.28% Left
44.39% Rear
50.11% Cross
Are you measuring the ride heights with driver in car (or simulated driver weight)? That will make a difference.
Cross is good.
+1 cross is fine so it's going to turn both ways as well as it turns assuming that is with you in the driver seat, all gear on.
As long as it's not low enough to bottom or change geometry significantly for the worse it's down to alignment.
If your ride heights change during a cornerweight session, the shop doesn't know what they're doing. Make sure the car is sitting where you want it when it goes on the scales.
I wish I could vote up a response times 11ty billion. Keith is absolutely right. Get the ride-height set exactly where you want it first. Setting the cornerweights should have no effect on ride height.
In reply to Keith Tanner:
Clearly I don't know what I am doing (no surprise there?) Anyway, if you have only coilover sleeves and not threaded shock bodies allowing you to set spring pre-load, how the heck DO you move weight around without changing ride height a little bit?
Adjustable length shocks and spring pre-load is another tuning myth, a bug being touted as a feature. But I won't get into that.
It's simple. You never adjust just one corner. Weight shifts from one diagonal to the other diagonal only, never front to back or side to side. So if your FD/RP diagonal is light and your FP/RD diagonal is heavy, you move the FD and RP perches up and the FP and RD perches down. All by the same amount. The car's stance will not change.
Thank you for that. I corner balanced the car exactly once and it lucked out that after changing one diagonal by one turn, cross weights were reading perfect, and this was on scales leveled with magazine pages and a harbor freight laser level so i figured much more monkeying around wasn't going to help anything anyway. I didn't know how to correct the 1/8" ride height change nor did I care. Now I do. Sweet.

Not just for ride height, but also very important for corner weighting.
