Why don't you check if you're bottoming out and go from there?

Whats the alignment like?

Sway bars?

 

I think I heard somewhere that DC2/EG front shocks are 1" longer than 88-91 Civic/CRX stuff, which could lead to bottoming out and the understeer issues you're encountering.

 

Yeah, fits on perfectly. Just change the front shock fork to a DC/EG shock fork.

This makes the fornt shock a tad 'longer', but if you have coilovers you can compensate. It it is a fixed spring, then it will set up a little higher.

If a DC2R sus. setup, then change the rear LCAs to the eye type. Rears are the exact same length.

 

I do know that 89 accord shocks will fit and EF and they have a little shorter stroke. So that may help you out. I have 89 shocks on my street car that is lowered, no bottoming out problems.

.....done all of the above.

devilchikn, the car isn't drivable currently - but I would like to order GC/ koni setup and can't figure out if I'll need dc2R or EF components.....

 

How about doing the ef front setup with rear shocks for the dc2-r? Or if you feel like swapping out rear lca's you can do the 88crx ones which are also eye style, just skinnier. I used to run the dc2-r setup on my crx and i thought it sucked *****. If you were to run a coilover that required some preload, you can kiss that goodbye due to the dc2's taller shock height. When i tried preloading my setup the car raised up in the front about 1.5 inches and i lost my natural negative camber. The rear was fine though. I suggest ef front shocks with the ef shock forks.

 

JIC FLTA2 DC2 (non-ITR) on my ED6.
10k / 7k , but I changed to 14k, 10k.

On 10k,7k -- the handling was terrible. The car tended to hop really badly and make it undrivable when cornering. Didn't understeer but I couldn't really corner fast because of the bouncing. Went to 14k, 10k and the hopping is gone.

I dont have a rear sway and I have a HF front bar.

So what are you asking then? If you still have your front forks and rear LCAs off the EF, then order the 89-91 Civic setup. If you have DC2R rear LCAs, then order an 88 CRX setup. I'd use the 88-91 front shock if I were going Koni/GC on an EF. Makes no sense not to.

See my sig if you need any 88/ITR rear (new) Konis

I would like to retain the 5-lug (for brakes), and the shocks/ springs for interchangability with my itr - that was the main reason for doing this... I can swap coilovers and wheels between my cars.

Here is the recent pm correspondence between myself and CRX Lee, which is of particular relevance:

Black R (5:10 PM 8/11/2005): hi Lee,
Have you ever dyno'd the apexi n1 (99spec) shocks?

https://honda-tech.com/zerothread?id=1336779
CRX Lee (11:00 AM 8/12/2005): I don't have record available to specifically confirm if we have tested those or not but I think we have done some N1s (are those the purple ones?). We have tested a decent range of assorted JDM product through there but have not as yet done a very searchable system to review and compare them. I have asked one of my employees to organize it better. To be honest, the very vast majority of the JDM stuff is pretty similar with the bigger variations being worse and not better.

As for your question about the EF and DC2 crossover, the rear shock are exactly the same and the fronts are of the same valving and basic dimesions (or close enough) but the diameter of the wishbone clamp area does change and the spring perch exact location and shape are different too. If you are using a coil-over system, then you have eliminated the the perch issues. So if you are needing to get new shocks, there is no advantage to getting DC2 parts over the EF parts plus you would then have to change the front mounting wishbone which are pretty readily available.

-neg 2.5deg at all four corners

-stock sway bars front and rear (it's a 91 si)

-old bushings everywhere

Why so much rear camber?

.....that's where the drop left it.

I have no camber adjustability fore or aft currently.

My intention was to get the spring rates and height done, then work on bushings and camber/ caster.

 

things i know from running all dc2/eg crap on a 90, take it or leave it:

front spindles are incorrect must use crx/ef/2nd gen teg
front upper a-frames are incorrect, must use crx/ef
front shocks will work with the afformentioned dc2/eg lower forks however, travel would definately be hampered without some sort of adjustable/shortened setup. they do bottom well before a short stroke shock would.
crx/ef front sway bars are all interchangable throughout the series

rear compensator arms are different,must use ef/crx
rear upper links vary very little if any
rear lower control arms work just fine
eg/dc2 22mm rear bar with beaks would take some 'work' to make fit.
no noticible loss of travel in the rear vs a dc/eg chassis to my knowledge and measurement. even with eg shocks.




edit...
removing some of that rear camber would help you out immensely. like at least a degree.
