Rear Camber

Postby GP » Wed Dec 13, 2006 10:54 am

Hi All
Just noticed that the rear camber is slightly different from side to side, I'm concerned that ther maybe a worn bush or something that's causing it.
Anyone know the standard specs?

Maybe one of your alignment adjusters has moved?

I'm hoping that's all it is, Anyway I've got it booked in for an alignment. They will let me know if there are any problems.

On a related topic....is it normal to have more neg camber set on the right hand side than the left? (this is without the driver in the car). Have they stuffed up my alignment?

I didn't know my alignment was set up in such a way until I had a look at my alignment sheet :shock:

Around -0.5 to -1 more on the driver's side. Don't have the sheet with me right now but from memory that's about what it is. Is that a stuffup? I was thinking it may be normal if there was more on the LEFT hand side, since the alignment has to compensate for the driver's weight. But not on the right hand side....

Got it done at Spinning Wheel in Woollomooloo after researching on here :P

That doesn't sound right Deez. Maybe you are misreading the alignment sheet?

Go back and have a chat to Stu to see whats happening, especially if your not happy with the handling they've dialed in. They have been very obliging to me in the past and have changed stuff when I wasn't happy with their initial setup. But dont wait to long.

Thanks for that guys. I'll follow it up with Stu. He's the short, stocky guy right?

Went home and read through the sheet again. Lucky I did so before calling Stu. Indeed I misread the sheet lol. Sorry guys :P

It is 0.08 more negative camber on the front right compared to the front left, and 0.18 on the rear right compared to the rear left.

Does that sound normal?

Sounds better than 0.5 and 1.0 :P

Like I said, if your not happy give him a call and have a chat to him. He will explain why he's done what he's done.

Take the car to someone else. I have been doing wheel alignments, Race Car alignments, building and designing race car suspensions for over 20 years and if one of my staff let a car that is as adjustable as a MX5 go out with those readings they would of been sacked immediately
For street use the left hand cambers should be either less positive or more negative than the right hand side depending on the size of the vehicle by approx 0.30 degrees, also the caster angle should be offset with more castor on the left of approx 0.30 degrees this is to help combat the camber wear and pull created by the camber of the average road.

I wondered about the difference between the left and right also the first time Stu set up my MX5.
Next time in I commented on the difference and following the alignment he had me get into the car. The readings came back to match left and right.
So the miss-match is just an allowance for driver weight. Mind you I have mine set up for track work not just road use so numbers will be different.
As for knowing his job, most of the quick Club cars use Stu to align their cars.
The results speak for themselves. :D

the camber will be even worse with the weight of the driver. As the lower to car the lower the camber.
