whats the difference between eg and ef's suspension wise? are they the same format wise and just different spring rates? or a totally different setup? i tried to search but i came up empty, if you have any good links please feel free to send me that way -Thanks

 

if you are thinking of swaping suspension from one to the other, don't bother. I really don't think either are good enough to be a good use of your time. As for the differences, i bet the EG probably had stiffer spring rates thanks to a heavier car. Also depending on which model your talking about some get anti-sway bar in places others don't. The suspension geometry is also going to be different due to different chassies. but i doubt radically differnt.

That's true for the most part. An EG naturally sits lower and getting rear control arms from the hatch won't hurt, they're lighter. Not as though it makes that much of a difference.

 

the ef front struts are also skinner than EG. And the wishbone on the EF is about 2" shorter. The back is the same

someone correct me if i'm wrong, but:

the ef uses radius rods and a single bar ("I" arm, i guess) lower control arm, while the eg uses no radius rods, but uses an "a" arm lca

rear suspension is essentially the same, design-wise. someone verify this but, actually i *think* it might be interchangable between ef/eg/da/dc.

 

The EG actually sits higher than a CRX.
EGs have slightly more suspension travel than CRX.
EG & CRX have a similar front upper a-arms.
EG & CRX have similar knuckles.
EG & CRX have different front LCAs.
CRX has front radius rods & CRX does not.
Rear trailing arms are identicle for both cars
Rear LCAs are identicle for both cars (except 88 CRX has ITR LCAs)
Rear Upper arms are same for both cars.
Rear Compensator arms are the same for both cars.
Sway bars are different for each model & trim level.
CRX Front Shocks are skinnier than EG
CRX Damper Forks are skinnier than EG

 

I checked the differences between my EG Si and a CRX Si once and it goes as such :

Front :
EF has a shorter shock with a longer fork. EG has a longuer shock with a shorter fork.
EF has an "I" style LCA with a traction bar connected to the front cross member. EG has an "A" style LCA. The part that connects to the balljoint, shock, chassis, is identical to the "I" style LCA of the EF but with a second part that gets a larger bushing connected further back into the subframe forming the "A" shape. The front sway bar also picks up on that latter part although I can't seem to remember where it is connected on the EF.

Rear :
EF has a slightly different LCA with a slight bend in it but the shock picks up in the same place. IIRC the shock fork is narrower on the EF, but it might be the other way around. The rear sway bar on EFs is not connected on the subframe but on the frame rails. Also, 88 model year received Type-R style lightweight LCAs made of sheet metal where the lower shock is a bushing and not a fork.

Hope that helps

Ever try to put a knuckle from a DA/EF on an EG? If you had, then you wouldn't have posted this. They are not "similar" and won't even get CLOSE to working.

 

Just wanted to correct you - the CRX/EF has longer compensator arms. The DA/DC/EG/EK share the same one, but the CRX/EF have longer ones.

How do I know? Bought 2 sets before getting the correct ones. If you use a DA/DC/EG/EK rear toe arm on your EF, you will have massive toe-in in the rear.

I know, old thread, but I would have saved $20 if I found the correct info earlier.
