Since nobody has been able to produce the control arm braces/radius arms, I tried to make my own. I used a combination of turn buckles and 1/8" aircraft cable to see what would happen. I hooked the turnbuckle to a hole on the lower core support of each side. I then wrapped the cable around the control arm and clamped them down. I had to loose all the splash guards cause they were in the way. The purpose of this was to simulate what radius arms do by locking out front/rear movement. Obviously with cable it would only lock out rear movement but I was gonna see what it does. I had to play with the positioning so the cable would not interfere with the movement of the tires. Also The tranny side there was plenty of clearance. The engine side the cable was coming very close to the AC compressor pully.

The result was right on the track of what I was looking for. In the rain I used to have a bad problem with wheel hop, especially with my Quaife differential. The wheel hop was very supressed although I was able to get it if I really wanted to. Most likely cause these things only brace backward movement and not both directions. NVH seems fine, no additional odd noises either. Another problem was my turnbuckles would work their way loose, but I plan to loctite them down so hopefully that will cure it. I'll have some pics available in a little. This just tells me how much we need those damn radius arms! I will keep playing with this setup as well, hopefully something will come out that works.

EDIT: this is what a radius arm does http://www.overboost.com/story.asp?id=460

 

Hmm sounds good but you could make one out of metal though. If possible you can design a bar like this http://www.nissanperformancemag.com/april01/ntec.shtml. I have a stillen G load under brace http://www.stillen.com/sportscars_de...=13010&page=1. Good luck.

EDIT: Could you post pics of this? I'm thinking of doing the samething to my sister's car but I can't quite visualize it.

 

nice eric, we'll have to talk more about this when i talk about the motor mounts. i have BAD wheel hop and i need to cure it.

 

Hey,

How about a bar that could go on top of the engine to somewhere on the chassis under the hood. I've seen this in a mag. where they have a pic of something like this on a skyline. This should eliminate most of the engine movement.

Peace

 

LOL polyurethane engine/tranny mounts will do that.

 

yea...and they vibrate the car to hell.....

I took these off after the experiment, I may try again with cables to the rear as well just to see what the effect of bracing the control arms are with wheel hop. SOMEONE HAS GOTTA MAKE THESE BARS.

 

Cheston, if I can convince one of the engineers here to work on the project, do you have like dimensions and stuff???

 

Who's cheston?

 

It's looks doable. Where you tied the cable to the chassis, in front of the suspension, how thick is the material. If it's too thin, you'll end up deforming that.

And I think Lime is dreaming about Chebosto in her sleep again.
