General regulations:
"All cars must have a full suspension system of the type produced
by an automobile manufacturer (i.e., springs, torsion bars, etc.)."

All motor class rule:
"Suspension:
OEM suspension mounting points mandatory. Traction devices
permitted provided stock mounting points are retained. One
working shock absorber per wheel mandatory. See General
Regulations 3:2, 3:4, 3:5.
Suspension, Front:
Aftermarket or fabricated lower control arms permitted, must use
original mounting points."

does this mean that i have to stay with the torsion bar setup, or can i convert to a coilover setup. thanks

 

I think your gonna have to be more clear on this one for me.... are you reffering to the front or rear?-pdang

 

front, sorry

 

If your refering to the factory traction unit, than no you dont have to change over? You'd want to go coilover setup with some sort of aftermarket traction control bar unit.-pdang

 

I take it you have an older crx/civic?

You can run a coilover setup. The part saying automotive type suspension is partly to prohibit cars with solid welded suspension (e.g. welded shocks).

Are you planning to use coilovers with the torsion bars, or let the torsion bar freefloat, and act as just a lower control arm?

 

??? now Im lost.

 

The older CRX/Civics used a lower control arm with an integral Torsion suspension INSTEAD of a coil spring. There is a tube that uses twisting action as the "spring". The spindle/hub assembly is attached to a strut instead of a dual wishbone setup like most newer hondas. There is no coil spring up front.

In this case, he can either convert to a "coilover strut" or better yet, a threaded body coilover strut. (remember that "coilover" simply means that the coil spring sits over/around the shock/strut.... not to be confused with threaded body struts/shocks which provide the height adjustment). Oh, they do actually make aftermarket torsion bars with different 'spring' rates.

My question was whether he would keep the torsion bar operational (which would basically mean he has two springs) or not. For those who have never played with a torsion suspension, it's really cool, because all you have to do to change ride height is turn a bolt in or out!!!!

Note: this post is intended for those who might be confused by all the different terms, coil/leaf spring, torsion bars, shock, strut, coilover, threaded body...etc.

I haven't found any pics online of the older Civic suspension yet.

 

thnx for the info.

 

i havent decided if i would use the torsion bars still or let them freefloat yet, but would probably have them still be used. and yes, this is on a 85 crx, i'll try to take some pics to show torsion bars...

 

theres a pic of a torsion bar.

is there any way to make traction bars for this?

 

I have a question for you.. I have a 87 crx si with the front end cut off like yours..what front end are you going to use? are you customizing a second gen crx 1 piece?

 

yep, i dont think i will have to do too much to get it to fit, but well see.. i have some pics of a first gen with a second gen front unmodified if you want to see
