Would or could you lower the rear with the blocks with stock front end stance?
From what I have read on the forum, you gain stability but cornering will not be as quick as stock. No one, that I have noticed, has complained about that so it must not be a big issue.
If you want to keep it leveled, drop the front the as much as you do the back. Cornering will be affected here but in a different way, you loose some angle. But then, how far are you going to lean it?
So far, I am 3" down front and back. Going past 2" is where the real work comes in and $$$, if you do it right (my idea of right). Up to about 2" down is relatively easy.
