Ideal ride height?

[Brew]

Lots of good info guys. Thanks for the Gustav link, I figured he had an article about it but wasn't able to find it.

I don't think that's quite true - the angle between the control arm and the strut would have to be less than 90 degrees before you started hitting the positive camber curve. it's not neccesarily the relationship between the control arm and the ground that matters in that respect.

Thinking about it, that does make sense.

If my understanding of what you are saying is correct, then the more camber you run, the lower you can run the car before it starts gaining a positive camber curve under compression?

yeah, I was thinking the same thing

of course you also have issues with bump steer when going really low, and I don't think that one is as easily dismissed. at least there are options for it though (tie rod spacers).

Yeah, I think bump steer is a fairly easy fix, well as long as you are doing what I'm doing... running Tie Rods that have Rose Joints, so u can space them down... I would assume you could do he same with the std e30 strut as they both dont have that removable mount to space it, like the E30 M3, I'm using e36 M3 struts so the solution should be the same.

I'm using a 30mm roll centre and bump steer spacer to start with, and if/ when I go 2 18's I'll increase it if necessary

I've always heard that once your control arms go past parallel (to the ground, at static ride height) your just doing more harm than good.
Which isn't very low, my car would need to probably come up a full inch or maybe more.

ANDRENY car was slammed and HANDLED like on railllssss


no but anyone have good success at the track with mid-high rates and different heights?

And also if there are any off-the-shelf options for adjusting bump steer.

If you are running e30m3 suspension, there are roll center spacers of different thicknesses you can install to improve your roll center and bump steer.
Also, Ground Control sells tie rods that allow you to adjust the height of them to help eliminate bump steer.
