I put the fronts in on Saturday, and played hookey from work to do the rears yesterday. Encountered no problems with the installation, but it is time consuming.
I have always been a bit skeptical about a suspension "upgrade". How can a stiffer suspension not comprimise the ride quality? I like the stock ride and definitely didn't want harshness.
How is the ride? Better than stock. It's amazing! The small road imperfections seem to disappear. I have been aiming for manhole covers to drive over, just to enjoy the new sensations. I think it's mostly because these use variable rate springs as compared to the fixed rate of the stockers. Whatever... it works.
How does it drive? Fantastic: flat in the corners, dive and squat are greatly reduced, and much sharper response. The P6000's seem like decent tires now.
How does it look lowered by just under 1"? Real nice.
