Tracking on a FWD trackday car
I've always set my Toe to 1mm toe in (overall, measure from rims) to help understeer. (well thats what i was recommended on my 4wd cossie)
But is this correct for a FWD??
Also looked thro Std ford settings,
FRST setting is 1-3mm toe out,
Xr2's are 2-4mm toe out,
1983+ Escorts arw 1.5-3.5mm toe out
Where do ford say the toe should be measured from?
i ask as the if the Toe is quoted in minute's or degrees it dont matter where its measured, but if quoted in mm, the points of measurement make a huge difference....
Cheers Danny

Yesterday, i set the car up in my garage, so it was level all round
Then i measured, 4 wheel Toe, camber and castor all round
It come out like this
Front, modded camber, and poly bushes.
toe = 2mm out,
camber n/s = -2' 30", o/s = -2' 15"
castor n/s = +0' 30", o/s = +0' 23"
Rear, Still std bushes and beam.
Toe, n/s = in 2mm, o/s = out 3mm = total in 1mm toe out.
camber, n/s = -0' 8", o/s = -0' 11"
After a day of playing with the suspension to day,
including
- shorterning the tie bars by 17mm each side, making new washers and fitting new poly bushes,
- cutting and welding the n/s tie bar to miss the gearbox casing,
- cutting the front arches and body kit to stop any tyre scrub ( as now the wheel sits 2 mm away from front of the arch)
- going for a drive to settle all mod's and bushes.
- Checking Toe and adjusting to no toe, checking camber and castor.
- and finally going for a hard test drive round the local track ( the loop)
It does seem to understeer less, but it still does round roundabouts whilst pushing it.
The setting now sit at
Front,
0 toe,
camber n/s = -1' 38", o/s = -1' 23"
castor n/s = +3' 00", o/s = +2' 45"
Rear, Still std bushes and beam.
Toe, n/s = in 2mm, o/s = out 3mm = total in 1mm toe out.
camber, n/s = -0' 8", o/s = -0' 11"
So now i'm gonna put more camber on fronts, and fit new poly bushes on rear and space beam out to get even toe of 0 toe, and put camber to -1' 30"
