s13 Roll Center adjustment

[Akihisa]

I know when you lower the car and the front arms angle becomes less than parrallel to the ground, when the suspension compresses, the tires will start to gain positive camber. My question is: Does a company offer different ball joints or control arms that lower the outside end of the control arm to keep the suspension geometry how it is supposed to be?

I sent your thread to the gurus.

spl has some different goodies for the tie rods, and front controll arms...suspension>multilink $572 for control arms..(actualy it says front lower control arm, singular so that might be fore one?)tie rod end set is $155

I dont know about the rear?

WTG?

You would have to be so low on an S13 to start losing camber. A Strut suspension won't start losing camber until the LCA and Strut are at a 90 angle. Which on a S13 would have to be tucking 15s to the rim bead or sometihng retarded like that.

It sounds like you just read the back half of Sport Compact Car's suspension articles and decided you needed 1000$ of Roll Center Adjustment.

Roll Center will affect the way weight transfers more than camber. If you want to adjust the Roll Center, SPL and Ikeya Formula sells LCAs to do it. However you'll need both the front and rear LCAs to make your can not handle like *** which will cost over 1200$. So I'd learn a little more about it anw drive the car without Roll Center Ajustment before you jump in head first.

I didn't read Sportcompact car. I know all about the suspension and adjustments. And yes, my car is losing camber if the suspension compresses. I was just trying to explain what I needed to you people. I know what I need and I was just asking if anyone manufactures the part I need, so don't try to insult me by saying I don't know what I'm talking about because you do not know me.

Thank you Red coupe for being helpful.

i just wanted to throw in a recomendation for SPL's tie rod ends too. they made quite a difference in steering feel on my car. they're a little expensive (though cheaper than other adjustable ones) but worth it.

Pics or BS.

You won't lose camber until your LCA is at a 90 degree angle with the strut not when its parrallel to the gound.

to get that amount of low you'll have to be tucking 15s and if your rocking 15s then there are better ways to make your car handle better.

its obvious by your post that you deffinitley do not.

tires dont gain camber.

if you are ready to drop 1k+ on a couple control arms, its obvious that you have a pretty serious race car on your hands, and you want the suspension geometry "like its supposed to be." please explain this in detail? since you have a race car and all.

"I was just asking if anyone manufactures the part I need"what part do you need? some kind of mystery magic balljoint/control arm is all i got out of your first post

there is no way your car can go so completly far outside of the norm as to loose camber on compression. your suspension would have to be completly screwed up for that to happen. go read a book and come back later

[Red coupe]

well to his benefit while camber may not be a major concern the tire will scrub laterally more during compression when the control arm is not parallel to the ground...but they may be right that it might not be worth your money to fix, just try to keep the amount you lower the car with in reason and you should be fine...

Unless you lower your frame to where it sits below the LCA ball-joint mounting height on the spindle, you won't have positive camber cain in compression.

On some cars, this si easy to do, on others nearly impossible. Suffice to say, on a S-chassis or Z chassis, it's quite hard to do. There are a lot of things at work here, half pof which I doubt most people take into consideration.

Also, roll center adjustment is folley for any street car, because you dont have the tools or time needed to properly asjust it..AND IT MOVES. Your roll center is a dynamic thing and changes while you drive. Setting it for only one situatio without looking at how it will change when the car is "in bounce" or rolling, etc is not a good idea.

I would highly reccomend learning more about static camber settings, etc than worryiing bout roll center adjustment unless this is a track-only car.
