engine and drivetrain Rear Camber

[jmon0261]

What rear camber adjustment eccentrics have people used ?

Did you use the toe kit as well ?

Are there any other options ?

When a 2002 is lowered the rear suspension gains camber. Often on race cars you end up with too much camber. This kit consists of 2 sets of eccentrics and slotted brackets. Brackets are welded to the inboard trailing arm pickup points and eccentrics allow you to adjust camber. Removal of rear subframe, welding and some grinding is required. We also offer similar kit for toe adjustment. Most racers will want both.

I tried my best to not injure kittens for this thread

Unless you're going to shortened struts, coil-overs and a full race suspension, you most likely can get away with flipping the subframe mounts.

So what's the plan?

I put a Dinan-modified rear subframe in an E21 320i and it works just fine. It is basically the same as the Ireland kit.

Time for the immortal question:

W H Y ????

If you lower the car an inch or 2, the rear camber follows

along nicely. Yes, you then need additional front camber,

but you really wanted some of that anyway.

If you lower so far that you have too much rear camber,

they you are too low and have no shock travel.

I know all the web sites say that rear toe becomes excessive,

but I don't know wtf they are talking about. At the point where you have

2-3 degrees of camber, you have about 1/16" of total rear

toe in, which is right in the 'safe zone' for good neutral handling.

The Ireland weld- ons are good. They work. You need to know whether

you want more camber, less camber, or some adustment either

way before you cut and weld. You get maybe 3-4 degrees

of adjustment with 'em.

If you're racing, yes, the whole kit is worth it. You have to know what

range your tires want for camber, as there's not enough adjustment

to make both radials and slicks happy. It's nice to be able to take

toe out to make it darty on safe tracks and add it back in when you

need the stability. I use the Ireland toe end and my own camber

end so that I can go between radials and slicks, and I have not

welded them. They have not slipped- yet.

For the street, if you wanted to take a degree or so out, yeah, the camber

kit by itself would work. Unless it's a REALLY serious track car,

though, the stock camber gain by itself is plenty sporting.

what I have found.

John, Bill and Toby - Thanks for the reply.

My 73 was lowered by the previous owner with

H&R springs ( 1 1/2 drop ??).

Bilstien sports up front, hds in the back

The back wheels have Negative camber. Not sure how many degrees.

I can get it measured, evaluated at an alignment shop. Visually to me it looks off.

My tires are now worn and would like to get this solved before I buy new ones. The tires have worn more on the inside. Here are some pictures. Hopefully you will see what I am talking about.

I have a boxed rear subframe, bushings, bearings and e28 drums is my next areas of restoration / re-hab for my 2002.

I will drive rallys and long Highway trips. Probably never take it on a track.

But many twisty roads.

There was some urethane in the front but have gone back to rubber and plan to as well in the back. Long trip / street comfort is my objective.

Hope fully that helps with the " WHY ?" or " WHAT" I am after.

Are their other solutions to getting the rear camber closer to even.

Thanks a lot for your time and knowledge.

should be able to get away with rotating your rear subframe mounts.

Here is a handy tool to add to your toolbox. http://www.amazon.com/iGaging-Digital-Magnetic-Laser-Level/dp/B002TDE9D0/ref=pd_cp_hi_0

Probably about the same price as what the alignment shop will charge you.

www.e30tech.com has a kit for 3 series on their Forum page. Click there and it will take you to the link and thread. I am building a setup for an e30 right now using standard off the shelf parts from McMaster Carr and the local steel supply house. I've got $35 into the project before the nuts and bolts. I haven't had the subframe off the 2002 yet to compare.

post pics when you get it done, I am having the same problems THANKS
