We’ve just fitted these to the car,and have a couple of questions.

we've set the coil overs to the same measurement on the back 2 and the same measurement on the front 2

The question is once we’ve lowered the car with the wheels on these are the following measurements we have
This measurement is taken from bottom of the arch to the centre of the hub
And we’ve done this with a laser level so these are accurate..


Front left 345mm
front right 339mm

Rear right 342mm
Left 346mm

So do we jack the car back up and alter the coilovers so the arch to hub measurement is correct or is it more important for the coilover measurment to be correct

also what measurements should we be looking to achieve

im looking for the car to be lowered but nothing ridiculous

its a weekend car car and will only go out in the sunshine ☀️

all help appreciated

 

don’t worry about it , i measure mine then fit them , now it’s time to play with the set up firm or soft , i set mine so the front was slightly lower , i run harder setting on the fronts than the backs , it’s surprising how a few minor tweaks change things , don’t forget to get tracking changed/checked as a change in ride height will effect it

 

Just to add this is a UK MY99 Impreza

and its going for geometery setup on Thursday

 

just get the height set before you get tracking done or you will need to get the tracking done again , the re bound adjustment at the top of the shock changes things quite a bit , i have one car set fairly soft and one firm , the tyre height has an impact too

 

If they are new coilovers, I would suggest you run them in for about a week or two. The spring will settle and sag a bit, then you can go adjust to the proper ride height. You may find that all four corners are of different height after broken in.
