J's RCA questions and answers

[cerebrous]

hey guys doing some research into the J's RCA.

J's RCA come in two version
02-04 DC5 & EP3 all years
- These are the ones with Green Adjustable spanners
- Will fit stock suspension

ITR & 05-06 DC5
- These are the ones with Blue Adjustable spanners
- These version are have bigger taper than the ep3 version..

See below for question,

What I'm not sure

will I be able to use Mugen ITR Lower Arms with my existing Ep3 knuckle?
and if so which version of above do I order?

Need help ASAP.

ITR ones have bigger taper but
is it bigger taper on the knuckle end or the end that connects to the lower control arm?

If I find answers I'll post

QUOTE FROM CLUBRSX: like the steering rod, the insert of the RCA adjuster is tapered. I know that there are differences between the JDM ITR and the USDM OEM RSX taper (one is smaller than the other).

Are these adjustable damn confused...

They are not adjustable.

The ITR lower control arms will require that you use the later larger dia ball joints. Unless you have Mugen LCA's sized for the smaller dia ball joints.

As far as I know they dont have the larger joints, they just changed the color of the spacer. The part#'s are the same for the green or blue spacers.
