Hi,

ED-EF have different front upper and lower control arms to EJ-EK.
But, for Honda Civic 87-91 ED-EF models, we do have;
KCA202 - front caster kit - adjustable radius rod kit.
KCA378 - front camber kit - off-set upper control arm bush kit.
KCA370 - rear camber kit - upper control arm - shim adjust.

Hope this helps.
Wojtek.

thanks not sure what an adjustable radius rod kit. is could you explain at alll or givve me a link to a pic>? also i take it your offset upper control arm bush comes with a preset castor improvment?
plus my freind with a ek4 has just pointed out my front lower wish bones are two piece and bolt together and castor can be improved even more by putting shimms inbetween them ?
and do you do upgrade front and rear anti roll bars for mine with drop links etc. i was thinking at least 20mm, thanks

oh just another question,, ;)

my cars running 180bhp its totally stripped out including the soundeading off the floor pan, rear wipers gone etc , not had it weighed but think its about 150kg lighter now. im running avo coilovers with setting 12 on the rear shocks and 9 on the front out of 24 and 400ft/lb springs on the front and 350 on the rear ,tyres are 215/40/16 so not much give in them ive just replaced the rear swing arm bushes for standard new ones as they were worn out everything else is standard so far planning to get a LSD soon, but it handles a bit crap it always has is there anything you would recomend doing i up'ed the spring rates from a 350/250 as it had far too much roll and was throwing too much weight about under braking, the rear wheels kept scubing as its lowered a bit which has caused major front camber issues and now it skips all over the road when breaking and at high speeds help!

Hi,
I'm :confused: now.
Can you please clarify which model you have?
87-91 ED-EF
91-94 EG-EH

Also, could you please give all the information about your car first, and then ask all that you want to know.

The more information you give the better your questions can be answered. Based on your last comments, I need to firstly clarify which model Civic you have. I also would like to know the ride height (centre of wheel to guard, front and rear, in mm), wheel alignment settings, sway bars used, and any other pertinent information.
Just briefly, in my opinion your spring rates are too high. I'll explain in more detail when you clarify the above.

i have a EE938005300629 which is the uk 91VT with the B16A1 aparrently only 303 were ever sold! its the same as the EF9 SiR the gen 4 civic . im not too sure of the ride height any more as its on coilovers but can set it to what ever , all sway bars are standard , i dont know my wheel alignment settings , and im not sure what you mean by centre of wheel to guard in mm? * ah just read it agian ok i measure from centre of wheel to where?>* what guard ? and by the way its now off the road for a bit so im open to offers on what ride height to set it too ;)
my wheels are 16" x 7 and ET38

[Wojtek]

Hi,
OK, thanks. I will assume you have a 87-91 ED-EF model. Please refer to my original reply for alignment kits.

Few clarifications;
KCA202 radius rod kit - the front suspension on this model is a double wishbone using upper control arm, and lower control arm with radius rod. Radius rod is connected to and locates the control arm fore and aft. It is attached to the chassis (crossmember) in front of the wheel. KCA202 kit uses adjustable (as opposed to not adjustable factory units) to allow for caster adjustment.

KCA378 front camber kit - this kit consists of replacement bushes for upper control arm. These are off-set for camber adjustment, but not for caster.

Ride height - we measure vehicle ride height from centre of wheel to guard (fender, wheel opening... etc).

I asked for clarification and more information on your current suspension set-up such as wheel alignment settings, ride height, sway bar (actual size), and anything else that may be of importance, to be able to answer your questions about the handling of your car.

I have already suggested that your spring rates are too high, and we would use softer springs (and shock valving if required, to match spring rates) together with uprated front and rear sway bars. This will improve handling and roadholding as well as ride comfort. Ride height is VERY critical on this model, due to its dramatic camber and toe alteration in wheel bump and droop. Suspension and shock travel must also be considered.

hi yeah thats it. thanks very much , my sway bars are standard 20mm at the front 15mm rear ,
rear ride hieght is 130mm cant give you the front because the wings are off but its was a lot lower , the cars had a 50mph front end impact you see , and ill be needing a radius rod anyway as one is bent tho i had referd to it as a front tie arm :s but then agian im not the expert ;)
clearly!
any way i also have a reactive rear lower tie bar but that was only on about a week before the accident i have no other strutbraces at the moment. if you could give me all the part numbers i may need for my application that you recomend especially for a larger rear sway arm (i was planning to get) as the car suffers form understeer too and ill order all the bits at once to save postage thanks :)

as for the spring rates i went that high because tien recommended a 407 front and 300 rear on my freinds ek4 with his tein coilover kit

Hiya,
OK, thanks.
So, just to recap;

Honda Civic EF.
Springs; front 400lbs/in, rear 350lbs/in
Shocks; unknown valving, set to 9/24 front, 12/24 rear
Sway bars; front 20mm (OEM), rear 15mm (OEM)
Wheel alignment; unknown
Ride height; unknown
Suspension/bump travel; unknown

Based on the spring and sway bar information above, I am surprised that your car understeers. Perhaps the answer lies in the "unknown".

My suggestions;
Springs; front ~315lbs/in (5.5kg/mm), rear ~225lbs/in (4.0kg/mm) - street/race tuned for race
Shocks; difficult to say, but try ~ 6/24 front and rear.
Sway bars; front 22mm (BHF32), rear 18mm (BHR32 - replacement for cars with OEM sway bar)
Wheel alignment;
front camber -1.5>2.5 deg
front caster max
front toe 0.0mm
rear camber -1.25>2.0 deg
rear toe 0.00 to 1.5mm toe-out per side

Hope this helps.
Wojtek.

by the way my freind with the EK civic already has your upper castor and camber top wishbones bushes he wants to know what other castor adjustment he could do if any ? its a 1996 ek4
and how can we change are rear toe?

[Wojtek]

Hi,
please see our fact sheet for Honda Civic EK;
http://www.whiteline.com.au/docs/fact_sheets/CK_Civic_EK.PDF

Rear toe adjustment can be adjusted using the toe-adjusting link at the front of the trailing arm.

Let me know if you need more help.
