i had' 'em on my ride a while back. i loved 'em very stiff on my setup. the yellows are the best shocks for the civic. you can't go wrong.

i'd recommend the following spring rates:

450 front 550 rear by gc
and yellows should be near the edge of the dampening, but you could probalby have gc setup them and revalved for your setup when you order everything through them.
