I know, search search search. Did I spell that right ?? Anyhow If I'd like to install some H&r sport springs, how much will my caster/camber be off ?? Will it be within specs or will I have to get some m3 cab's and get technical with the rear end ?? Ive got the front end torn apart and waiting for new control arms, stock cab's ect. Kinda dont want to spend the money on shocks and springs, but while Ive got eveything torn apart, may as well. I guess to sum it up......can I just install the springs and shocks and walk away with out having to modify anything else ??:???:

The short of it is, yes. H&R Sport doesn't drop your car down that low.

yeah, if you're getting excessive camber from a set of spring springs, something else is wrong.
you'll want to have your front toe checked for sure though!Comment

The rule of thumb is a 30mm drop is the limit before you need to facilitate adjustment for Camber, Caster (and Toe in the rear). H&R Sports will put it just about right there (be extra sure that you get the correct set for the application).
On another note: Offset LCABS Require more changes than most everyone seems to know about. Not really the greatest idea on a "street" e30.Comment

m3 CABs wont fix camber fyi, get them anyway thoughYour signature picture has been removed since it contained the Photobucket "upgrade your account" image.

The only thing I could possibly see is that it reduces straight line stability. I experienced this in my E36, but after I got an alignment with reasonable toe in it disappeared.

offset LCABS toss the arms forward in an e30 it gives you more + caster but also changes the rack geometry, the included angle and scrub radius those things should be addressed (they are on the M3 chassis...different ball game)Comment

As to all the what's and whys about the LCAB offset dilemma, when (if) I get the time, I'll post a brief write up about it.
But to the OP, you should be fine baring any bent worn or just out of spec shit going on.Comment

But, no It's not really the same car.
True However, when you swap all of that on to an e30 (and move the rack into the forward bosses in the sub frame) it works pretty well.
You see, I was at BMW AG and NA (about '82 to '91) when all that shit was being worked out. It was my job to tell Engeneering when and how they screwed up.Comment

you are right, it does affect those things - but I doubt you would even be able to tell any difference. it's not like it moves the wheel center 5" forward or something. it's like a 1.5 degree change. And for me, the real benefit is dynamic camber - since the ix has so little caster, this makes a big difference on the outside wheel in a corner.
seriously though, if you're going to say don't use offset CABs because it messes with suspension geometry - you should also say don't lower your car, put stiffer springs on it, camber/caster plates, wider tires with lower offset wheels, etc. etc. because ALL of these things affect the suspension geometry, and in most cases for E30s it's not in a positive manner. But we still do it anyway because the benefits outweigh the drawbacks.Comment

I put offset bushings on my E30's, and I dont have a problem with them at all.. Great for my street cars (and a hell of a lot better than the worn OEM pieces).Comment
