I found a good deal for a set of Ground Controls off a 2000 SI along with tokiko illuminas. However my car is a 1999 Civic EX and I know that the spring rates are different but I was wondering what effects would it have on my car if I were to install the GC and the shocks made for an SI. The thing im worried about is my car being bouncy as a mofo so can anyone help me out here?

Thanks yall

 

They will work fine h:

 

The chassis is exactly the same. So, if you like the way that setup rides in an Si, it will be identicle in your car.

 

but isnt the problem because the SI comes with a b16 (heavier engine than mines) so that why the GC spring rates are higher. Imma go for it since I think it's a steal. 400 bucks for tokiko illuminas with the ground control coils used for only 500 miles.

 

The front end might ride a little more stiff than it would on an si, but it won't be very noticeable.
