An Another Idea For Rear Camber

Ok,

Let my explain by a pic:

The idea: a under rear strut from some factory bolts and adjustable in the middle for lenght

thats where the shock mounts, it wont allow for camber adjustment.

^yep.

I think the brace as you have it drawn there would affect rear toe more than anything.

those brackets aren't very stiff as well, and would likely bend under much force.

Yes true!

What about these holes?


Cheers.

i want to take the dumb test

That's not going to work, The problem with camber is the alignment of the arms to the subframe. If you take off your shock/spring and lift the arms up and down, you'll see the line of travel. You won't be able to fix camber with such a simple theory.

is there anything we can do for rear camner?do coilovers make it worse?

Lowering the subframe will help, but probably slotting it is the best right now.
Searching for that should turn up more info.

people have been trying to solve the rear camber issues for years with little to no improvments.

swapping a s13 rear assembly will allow you to fix the camber but its alot of work. you dont have many options with the s12... either learn to live with it, or dont lower the car.

i dont have camber issues, tyvm

Not that it matters when it's just a rolling chassis...

doesnt roll either actually

lol that z31 thread is crazy. im gonna pretend i never saw it and just go on living my life with camber. its really not so bad when tires are free...

haha yeah, that is true, but when the results of that thread come thru it will be a pretty solid answer to this issue.

I'm gonna raise my car and think about it.

slot the sub frame if you go really low. use cam bolts if you just lower a little.

Do you know the spec for such cam bolts?

How this work? http://cgi.ebay.com/ebaymotors/SPC-REAR-CA...bayphotohosting

Cheers.

The cam bolt won't solve the camber issue when you lower your car. The way the rear suspension is designed from the factory, when the wheels move up, they gain negative camber. So when straight, they have no camber. The more they move up, the more they gain camber. It's not a fixed amount, so what you suggest will only change the camber when the suspension is not traveling up or down.

Like Henry and others said, this won't work, because the problem lies in the way the trailing arm connects to the crossmember. The hinges if you will.

Here's how bluke1 has it on his car. His car has slotted hinges on the trailing arms:





As he put it: "it may not be the same as some camberplates some people make, but this car has been raced hard for over 20 years and there are no structural problems with it. just some steel and good welding."

Since everyone keeps asking about the camber info, this is going to be the next biggest thing. I'm pretty sure it will work, because I was going to do this to my own car but Gary advised against it until he was finished and worked out the tweaks. Sounds good to me haha so I don't have to deal with the minor issues. Since he will post all of the info there to get people started, I will personally reproduce this for personal use.

It should start at page 5. That's when the fun stuff happens. The other pages just go over the currently known camber mod and ideas thrown around to fix it. Enjoy! Oh and this WILL REQUIRE MONOBALLS or HEIM JOINTs to work because poly or rubber WILL BIND. I already have plans thought out for that. It will probably be a monoball bushing with a circlip to make the actual monoball replaceable. Expect this setup to be VERY EXPENSIVE as it will be custom.

If you don't get it, it changes the outer pivot point(mounting hole) to adjust the camber of the arm. I also want to see more of Bluke's picture cuz that looks really interesting too.

Well Sterling is going to visit him soon, before he treks out here. So I hope he talks him into jacking up the car, so he can take LOTS of pictures of that camber adjust design.

I'm gonna photoexplode on his car! if he'll let me...

but yeah, once that Z guy figures all that out, it should be a pretty cherry solution.  if you only had to go a degree or two, you may not need heims and all that stuff, but I'm at a solid -3.5 rear camber now, with more to drop, so I'll need everything I can get.

Seems some thread i posted, were disappeared or erased. Moderator censured? Can you send an pm to me for such things, thnaks

Nobody erased a thread of yours as far as I know. ??? What was the thread/post about?

Euh one talked about that i was agreed, it may placed on the post n6

The second talked about bmw e30 with a link, placed like 18/19 range

Sterling and I have been reorganizing some threads if they have useful info, it may have been combined or renamed. Or maybe it was thre and you missed it. ??? We wouldn't delete it tho.
