Coil Over ideal Height

[French]

HI Guys

I'm about to fit my H&R coil overs, but wanted to get and idea of the ideal height, Obviously I would want to go a bit lower than std like 25mm, but is this ok, any wheel arch to wheel centre dimensions ?

Thanks

Fitted the rears, and adjusted to information with the KIT, it looks ok, will see once it's settled down and can adjust to suit

Doing the fronts today.....seems like months since the car was on the road
