Front Wheel Alignment / Tracking / Camber
Can someone give me some figures for front wheel geometry settings
Im after a safe starting point for tracking and camber.
Car is a Ginetta G27, Zetec lump, live rear, no ARB up front, LSD.
Im setting the camber myself, but going to attempt to let a local garage do the alignment.

I would look at 2 degrees neg camber, and wheels parallel.
Easy to set the front wheels with 2 bricks, 2 straight edges and a tape measure.
Not sure if you can set caster angles, they are often forgotten about but can make a massive difference to the way a can drives.

Thanks!
I shall have a go tomorrow and use the garage as a last resort.
The car doesn't allow for camber changes without changing some spacers, so have left at factory settings.

I run the front of my G20 at 2 deg negative camber and parallel toe too so yeah that's a pretty good place to start.
Caster is fixed and measured at 1 deg one side and 2 the other - the car has virtually no self-centering effect whatsoever and needs steering out of
corners, if I ever get round to doing something about it I'd aim for 5 or 6 degrees.
ETA - after setting it up on a 4 wheel alignment rig I then checked the camber with a good quality calibrated digital inclinometer across the hub and
got measurements within a tenth of a degree, so that's a pretty good way to get it well set up too.

Most folks are about as happy as they make up their minds to be...

To camber and castor I made one of these:
https://www.merlinmotorsport.co.uk/p/ada-castor-camber-gauge-adaccg
Printed the picture as large as I could, glued it to a board, drilled a hole for the plumb line, job done. The instructions are online for castor,
very simple.
5-6 degrees castor is a lot. 3 1/2 -4 is pretty good. That is that I use on my Spitfire. (and the above settings, they are probably good for most RWD
cars)

Wouldn't you have to print the image to exactly the right scale for it to work properly? If you don't then the plumb line will not cross
the curve in the right place for the calibration.
