it's def. a good price for buy it now.

but the big gain of buying ground controls is getting custom spring rates and making the rear springs stiffer than the front to help induce oversteer. that alone makes a big difference in handling, and i find the stock spring of ground control too sponge for my taste. i would contact the seller and see if he's willing to get you the ground controls for the buy it now price and you pay extra for custom spring rates and buy those. that'd be a better setup. i wouldn't buy a pair of ground controls if i didn't have a stiffer rear suspension.

if you get those i'd look into getting some kyb agx's and having them shortened & revalved to the spring rates you got on your ground controls. i wish dearly i'd done that when i purchased my koni's my koni are blown already within' a year of use cause of my stiffer spring rates and extreme lowering.

if you can't swing the price of shortening/revalving of the kyb's. ground control sells upper crown that protrude 1" higher than the stock civic crowns, effectively giving you 1" more travel for your shock.
