Maximum Possible Drop On Xa Coilovers

I'm just curious about something. What is the maximum possible drop on Pedders Xa coilovers for the rear if the coilover is maxed out to its lowest setting? Please list that measurement in mm as the distance from the bottom lip of the wheel to the fender assuming it's a 20" wheel. I'm trying to see if my bushings are holding up the car or not.

Thanks!

Pedders, I beleve reccomends no lower than 660mm in the rear because of CV joint angle.

I know their recommendation, but I'm asking what the maximum possible drop is. Do you know that?

I 'm at 650mm,with 10mm preload and there is about 28mm of thread exposed.So I would guess you could go as low as 635mm IF IF IF the lower cup(mount) has 28mm of thread left in it.

When assembling the coil-over,screw the lower spring seat up against the spring until there is no vertical play(make sure the spring is seated).Then screw the lock nut until it contacts the spring seat.Then without moving the lock nut,tighten spring seat against the spring until there is 10mm gap between the seat and nut.Be precise,I used a digital vernier caliper.Now screw the lock nut up against the spring seat and tighten the lock nut against the spring seat without moving the spring seat.You now have 10mm preload(trap).
