Hi
Can someone tell me if I change the camber on the rear will that also affect the toe.
If it does is it easy to say by how much the toe will be affected if the camber is changed by 0.3 degrees or 1mm shim will the toe change by a certain amount.
Thanks
Paul
Changing camber shouldn’t change toe whether doing it at front or rear. The wheels are still pointing in the same direction as before. We’ve changed the camber on mine both front and rear several times in the last few weeks without stringing it up each time.
Please tell me I’m wrong though, those of you with special geo knowledge.
At the rear, surely it will depend on how your toe links are set, so how much bump steer you are running.
On the front it deffo changes the toe as you aren’t changing the length of the steering arm when you simply take out camber shims from the top mounting.
OK, just thought about what I have actually typed and on the front, no it wont change the toe as the steering arm isn’t independently fixed to the upright.
The heat is getting to me.
I will stick by my view on the rears though, unless someone can tell me different

For the rear the measurement you take at the correct ride height should be the same though no matter what the camber is. From what I understand it is only when the suspension compresses the toe changes.
Does that sound correct?
This all started from a visit to a garage to get the geo checked. It was a complete waste of time and the guy did not understand how to set it up even though they said they did.
Hi, its simple geometry realy. SeanB is right.
First of all the question is not so relavant because the static toe is easy adjustable through rear toe link or front steering arm.
On the front it wont change as the steering arm is not fixed to the wheel carrier. The shims actually go between the steering arm and the wheel carrier. The wheel carrier gets more camber but the geometry stays the same.
On the rear its different as the toe link connects to the wheel carrier. It however does that almost parallel with the lower control arm so as long as you shim the upper control arm the toe wont change much and when you shim the lower it will change a lot.
We need diagrams for it to be simple �
Geo ,I must admit is new to me …
Used to change toe to affect turn in and height to help roll but that’s about the limit of my tinkering…
Just thought this through again and yes Sean, front shouldn’t change but rear will. Didn’t think about the toe-links.
I thought you could shim both up and down but now had a look at my car and seems you can only shim the upper one. So remain with my last post though that both front and rear won’t change toe when adding camber.
I a sure you are right the rear toe will stay the same unless the ride height changes.
I should have known better and taken it to someone who deals with Lotus.
Any recommendations for geo in the Nottingham area?
Paul,
Take it to Martin Edwards in Quorn, Leics. He is pretty good at that kind of thing. My car is in their hands for any major work…

Hi Kurt
Do you have their address/phone number?
I have heard of them before but never managed to find their address.
Cheers
