So why did you do that? Just because the tires are rubbing?

And are those metal?

Metal bumpstops = really bad.

Not only can it do damage to the damper, when you hit it, your spring rate will suddenly go to infinity, possibly causing you to lose control.

Looks like the wheels will compress like an inch to inch and a half before hitting those bumpstops...

Argh...

Please tell me there are poly bushings between your shock body and those stops!

What you need to do is pull the springs, wrap a zip tie around your damper shaft and see what the highest point the shock body travels to on compression before it hits the wheel well. Then buy some micro-cellular polyurethane bump stops. and stack/trim them down to stop the shock body movement at the point that was located by the zip tie.

As was mentioned before the point is to have a controlled progression of spring rate as you bottom out. Not to go directly from 7k to Infinity. You will loose control.

These are cheap:

Also, if you're 3 wheeling, you are running too much anti-roll bar on the end of the car that's lifting.

He still has the Tein bump stops underneath the dust boots.

What you should really do is get a big hammer and pound the wheel wells. No sense in reducing suspension travel just to solve a little rubbing.

you obviously didn't read that I have the Tein poly stops under the dust boot.... they are actually softer than the poly we're used to in control arm bushings. Please don't suggest I randomly created the length of my stops... why do you think I put the assembly back on the car without the spring...?

I only three wheel when I traverse an uneven surface. My suspension has much more travel than most of you guys; at the ride height you're showing.

Haha, nice vid.

But like I said. Just get a hammer back there and beat on the inner fenderwell a bit.

Rubbing solved. Still have full suspension travel.

if you consider the length of the exposed shock shaft and the height of the bump stop under the boot, you would almost have to be at stock height to get those to bottom out; that or run smaller wheels. Plus you would have to jump the car, to bottom them out.

I did that video to prove to a Jeep guy that a clutch type diff can provide a full 100% lock... He assured me it wasn't possible. I felt an example was in order.

I know it only rubs when you three wheel, but I'd rather have that travel and not use it then limit the travel and have something happen where I needed it.

Do you just not like the idea of the hammer?

Your suspension don't have THAT much travel, although compared to most guys on zilvia, yeah, sure.

Get some tender springs and and you'll get another two inches or more droop, and your wheel would be touching the ground there, on both sides.

they're not but like I said its not very often I would ever rub unless I was traversing uneven surfaces. Not to mention this is ONLY a problem with a 245/40 and not to mention, I'm only running ~-1* of camber in the rear. This is far safer than bottoming out the tire on the wheel well. You don't think a stiffer setup would hope too? I've chosen a more stable arrangment than those who become air born when cresting small bumps....

we're speaking in relative terms here.... I would say my Jeep has just over 20"

I know but its quite a feat to get into my garage. I think this is more than acceptable when faced against such a change in surfaces.

Then why slam your car? These are the sacrifices we make with a lowered car, I think you've actually said that before in here. I've limited travel, as compared to when I would rub, by only an additional 3/8" for tread clearance; this is not a huge sacrifice. Besides, that part of the fender will not stretch well and could cause the outer skin to buckle. The clear solution is over flares, and to just remove that area. We all know there isn't that much room back there. The problem is that I prefer sheet metal back there encase I blow a tire. I use this car for drifting btw...

Because a low center of gravity with a corrected roll center is awesome.

I would rather have my chassis scrape the ground then my suspension bottom out.

Heat it up. Hit it with a hammer. It'll stretch.

and doesnt that 3 wheel jazz also happen when you run a bunch of preload?

I remember when i first got my coils a few years ago and i had no idea how they worked i gave them a bunch of preload and i would 3 wheel going up the smallest thing lolol

now i have 0 preload and that shit stays on the ground like always. and its the car in my sig lolol

I can see that, but there is a limit and I would prefer to have better ground contact and more suspension travel than bounce all over the road. We'll agree to disagree on what should hit first. I'd rather not hit the chassis on the ground. More clearance isn't necessary, this is a compromise I've made. You have yours and your car will act uniquely different than mine.

this is 3rd gear on a slanted bank, and I still wouldn't bottom out. Like I said, the car is quite predictable responsive.

That's how mine is too.

After experimenting with the stock knuckles, I have come to the conclusion that to achieve more angle while reducing the chance of over centering, you need to move the tie rod end pickup points OUTWARD from the stock location, that way it will achieve more angle at the wheel, but at the same time increase the angle between the tie rod and the steering arm on the knuckle, thus reducing the change that they will line up enough to cause over centering.

The angle compared to the ball joint appears to be the same direction as mine - you just don't have the bend in the knuckle that I see in my picture...and yours looks to be angled more. Am I looking at the wrong thing?

Just did a bit of modification this week, corrected it as much as I could by messing with the Godspeed hardware.
I replaced the inner rod end with some QA1 bearings, but the outer ones are the stock Godspeed ones.
The outer bearings are pretty stiff though, do you guys think they'll work themselves looser as I drive it?

Maybe I should just replace the outer bearing and use a bolt as well...

It might loosen itself, it's hard to tell.

What you can do, is press those bearings out, measure their O.D. (I have one sitting in front of me right now, but chances are, these things are so shitty that they're not the same O.D. batch to batch, so you're better off measuring your own, plus I don't have my caliper in front of me right now lol), then soak them sons of bitches in PB Blaster over night.

Then measure the I.D. of the bearing mounting cup. You should find that it's so shitty that it's out of round. Then from there, just try to open up the cup a bit, to within .0002" of the GS bearing's O.D., that way the bearing will pop right in with a very light press.

Once the bearing is back in, just take a breaker bar, or an extension for ratchet/sockets, and just work the bearing around.

Part of the issue with these bearings is that, they're in such an undersized bearing cup, that is out of round, that it's literally squeezing the bearing's race, thus preventing it from moving freely. That, and the bearing themselves are a little bit stiff to begin with as well.

Yep, my chinapseed arms were so much of a press fit the cheap steel of the bearing races actually "smeared" as they pressed it in with a 30T press or whatever. They only came out with lots of cursing and lots of heat. Snapped my bench vise in two as well on one of them... Grrrr...

Opening up the cups a bit definitely helps the bearings at least sorta rotate.

Hmm, that was my sneaking suspicion since the guy that made his own arms had problems like these when he pushed his bearings in.

I guess I'm gonna mess with this some more this weekend!

Using a harbor freight 1.5'' wire brush actually opens the chinaspeed arms really well since the metal is so soft. Try that.

I used the 60 grit replaceable sanding drums for a Dremel at 8000rpm.

Small enough to maneuver and small enough to really work on one spot to bring it back to round. You can also go all the way down to the bottom of the cup with it too.

the reason why i like the wire brush is because its easy to get a round hole, and it takes off metal slowly, took me about 3 tries to get to 1.498''. Worked good for me and coster like 2 dollars.

Meh... either way.

So are your's seriously in the dumpster but still sitting around? Or have they been picked up by the trash people already?

I'm asking because I want to see if those cups can be opened up for the bigger bearings that I wanted to run without any ill effects, or if it will make the cups too thin, and thus dangerous to do so.

If you still had those arms sitting around, I was gonna see about taking them off your hands for this purpose.

Yep, it's slow material removal with the wire brush, that's how I did it. Gives a nice circular hole.
