My friend gave me so lowering springs off a 91 Civic Si with a b16 swap. Two of them are are bigger than the other two. I installed the smaller ones in the front, but it did not lower my car. Does any one know which ones go where on an 88 EF Hatch?

 

those will work but the taller 1's go in the front so the motor weighs them down if u put them in the back the rear wont lower that far i made that mistake maybe the springs are too stiff motor does not way enough to lower down i would get rid them and get one's made dor your car just my opinion hope this help's

 

far as i know 88 suspension is way different then 89-91 efs. so that might be your problem.
Taller is front.
