Making relative camber changes

[LennyM1984]

Hi,

I'm hoping that somebody knowledgeable can sense check my logic on this...

I have a Porsche Cayman which I use for track days and weekend blasts. It is currently setup with -2.3 camber on front and -1.6 on the rear. Given that my track day season will shortly be over for the year, I was thinking of dialing back the front camber a little to ~1.8-2.0 negative.

The simple way to do this would be to take it to an alignment place but I don't really fancy paying for another 4 wheel alignment and I actually have the tools and ability to adjust camber at home. The issue I have is that I don't have a perfectly level place to do it.

So here's my thinking...

If I know the current camber values (maxed out), can I use my camber gauge (which has a "zero" function) to make relative changes on slightly uneven ground. Ie. If I want to reduce negative camber by 0.5 degrees, can I simply measure whatever it is at the wheels on the uneven ground (which will be different to the 'true' measurement) and then move each strut +0.5 degrees relative to that measurement?

Example:

True measurement = -2.3 all round
Measurement on uneven ground = -1.9 Right, -2.7 Left
Adjusted measurement on uneven ground = -1.4 right, -2.2 left
True Adjusted Measurement = -1.8 all round

I know it won't be perfect due to the fact that uneven ground will mean uneven weight distribution but I guess that it ought to be close enough. I can then just reset the toe and go on my merry way.

Does that make sense or have I overlooked something hugely important?

Note that you'll have to adjust the tracking after you change the camber.

For sure. Setting the toe is a little less, 'perfectly level' dependent though
