Ultra low king springs safe?
 

Hay i currently have a set of super lows in my 02 impreza but the front seems to be that touch higher than the rear. So i was going to put ultra lows in the front.

Just wondering is there is any safety issues or any other issues with the [B]ultra low king springs[/B]?
Thanks for your help

Roll centre issues.

Mismatched springs = gay
Lowering springs that lower 50mm = struts will wear out faster

Technically there is nothing wrong with what you are doing though. If you are that concerned about heights, I would be running adjustable coilovers rather than constantly changing out springs. (i.e. put in new fronts, rear will look too high etc etc)

If you're already running lows I don't see a problem apart from height issues (100mm) I've got king standard in front and low's in the rear of my Liberty to even it out as the Bilsteins seem to be a shorter strut than standard.
