Not sure if this is exactly what you're looking for, but Kodiak Racing Wheels sells wheel shells/rims/barrels/whatever you want to call them. http://www.kodiakracingwheels.com/shells.html I know a couple people who have used them to resize 3 piece wheels for different cars and I have used...

Unclysyd, I don't want to use rubber bellows for something like this. I'm looking for something with a smaller constant OD to fit in a smaller area. It seems anything on that any rubber bellows that I have found that will provide enough force are too big for what I need. Rizwa1n, the...

Thanks Mike, I was hoping to find something off the shelf before I had to start making custom order quoting phone calls. Monkeydog, that's not what I'm looking for, that's what I'm trying to find a better/cheaper way to do. I'm looking for alternatives to that.

That does sound like something that would work. Do you have any idea on who would manufacture something like that. I will search more later, but I'm still having trouble finding something that will work. What I would really like to find is essentially a metal expanding donut. Basically a...

I looked at firestone's offerings and they didn't seem to have anything that would work for this. What I would really like to find is essentially a metal expanding donut. Basically a spring spacer that would increase height with air pressure. I am also open to other ways of changing the...

I'm cross posting this with the ME Other Topics sections, just in the hope that someone who can help might see it. Hi everyone, I was hoping someone might be able to help me find something. What I'm looking for is a cup style air cylinder with a hollow center. It is something similar to...

Hi everyone, I was hoping someone might be able to help me find something. What I'm looking for is a cup style air cylinder with a hollow center. It is something similar to this: That is from a kit that is used to fit over a conventional coil over setup for a car to raise and lower the...

But you never clarified for me what exactly you meant? Refer to my post directly after your first one, there were a couple questions I had in there. And I think you took that a little out of context. 1" is arbitrary. I'm just trying to figure out the contribution of the ARB to the wheel...

I don't think the sign is wrong, I think the magnitude might be wrong though. I'm trying to essentially model the roll bar and spring together as another linear spring. So I think I'm underestimating the amount of spring rate the roll bar is adding. At first, I was using the rate of the bar...

But I'm talking about steady state load transfer, like a skidpad situation. And trying to estimate spring/bar/wheel travel. And for right now, I'm just interested in the outside wheels. I'm not sure exactly what you're trying to say. I didn't split up elastic and geometric load transfer...

I think Matlab is just as hard to check if you aren't the one who wrote it. I don't know, I'm used to the spreadsheet, so it works fine for me. It started a lot smaller and a lot simpler and then sections got added on. So the previous sections were right and didn't need to be touched...

Greg, Well then you should've seen the one I've been working with. I cleaned that one so hopefully it would've been easier to follow. Well what would be easier going over the calculations of just discussing the method of figuring this out. The thing is, I think I remember verifying my...

Greg, what do you mean, about single wheel bump arb load? Do you think I'm just neglecting part of the arb's contribution during cornering? As for the calculations, I'll start with the arb stuff. I was provided a bar rate of 621 lb/in. Which is just the amount of force to move one end of...

I wouldn't think this would give me as many problems as it has. I have a working spreadsheet that takes inputs, i.e. weights, springs, geometry factors and calculates wheel rates, damping coefficients, roll rates, tlltd, etc. Most of the calculations have been verified, but I'm having...

Norm, that sounds like exactly what I've been doing with it. I start with natural frequencies, then look at roll rates and tlltd, and always check wheel travel/g and compare with camber and toe curves and keep tweaking it until I'm happy with how it looks on paper. And then real world testing...

Norm, the one car has a -4f/2r RCH and the other has 2f/4r RCH. The first one is a MacP strut car substantially lowered from it's designed height. And these are just estimates based on the information I have and was able to measure. I never made a true model for either of these suspensions...

I think it's hard to remain in the softer is better school because there are so many compromises with vehicle suspension. Depending on what you are starting with, ie production car turned track car, race car built from the ground up, etc, you will either have more or less boundary conditions to...

Just another question on the same thing. What material do you think would be best to use for the lower strut mount and for the bearing surface between the lower piece and the shock body. Dave, you said you used bronze, what would other good options be. I would like to use an aluminum tube for...

Dave, that sounds like what I was planning on doing. I would like to make a new piece to replace the stock strut mount and this piece will be threaded so I can adjust height and preload here. The shaft will be bolted in at the bottom and I was thinking of using a bearing at the bottom. I...

Well I just got off the phone with a rep from Bilstein and he said they they didn't offer a take apart strut cartridge or insert. He also seemed to think that the only difference between they're strut cartidges and their regular shocks was the way the nitrogen is filled because the struts don't...
