Looks really good Geo, i would align it again to be safe, but you might be OK without it.

Personally I would align again though.

Yes and no.

Whenever ride height is changed, it changes camber and toe settings up front on a MacStrut. Lowering increases camber, increased camber increases toe-out. So lowering/raising it may cause your alignment to be out of spec or be unfavorable enough where you need to have it re-done, especially if it's a significant change in ride height.

But if you're only moving the height adjuster like 2 full turns? Insignificant.

Thanks guys..

Anyone know if i would need to take out the rear strut and spring to adjust the hieght? or is it the same as the fronts?

The rear looks the same as the front..

Any input would help again.

Thanks

Normally just spanner the collar around just like the fronts.
If you have a ring pair, lock them back together, or if KW then probably a set screw to lock them?

Think seriously about corner (cross) weighting the car.
Its likely that is weight balance will be all over the place now.

Having equal height won't mean equal cross weigts.
And a well balanced chassis even the most numb drivers can feel IME.
Maybe a $300 job or so? But worth it to get the best out of the other mods (which werent cheap?)
