My MGF has poly bushed suspension throughout (i.e. tight compliance at the rear) .
A 4 wheel tracking report shows -0.05 on each front wheel and +0.06 on each rear wheel.
Is that correct?
I think the front be +.0.05 per wheel (not minus).

I too am interested in this as my MGF will be getting done soon.

HERE is Dieters page about F tracking.

Front


Rear

Here are the settings from the 4 wheel tracking computer

MGF MGRover RECOMMENDED TYRES and PRESSURES - All models (EXCEPT THE TROPHY)



Wheels and tyres -(no other arrangements are recommended):

185/55 R15 V Goodyear NCT3 fit to 6 x 15 alloy wheels - FRONT only
205/50 R15 V Goodyear NCT3 fit to 6 x 15 alloy wheels - REAR only
215/40 R16 Z Goodyear Eagle F1 fit to 7 x 16 alloy wheels - front & rear

175/65 R14 T fit to 5.5 x 14 steel spare wheel only

Wheel alignment:

Front 10' ± 6' toe-out
Rear 10' ± 6' toe-in

Tyre pressures lbf/in bar
185/55 R15 V (front wheels only)- 26 lbf/in ......... 1.8 bar
205/50 R15 V (rear wheels only) - 28 lbf/in ......... 1.9 bar
215/40 R16 Z (front wheels) - 24 lbf/in ......... 1.7 bar
215/40 R16 Z (Rear wheels) - 28 lbf/in ......... 1.9 bar

175/65 R14 T (spare wheel only) - 30 lbf/in ........ 2.1 bar

I gather from Deiter's site that toe in values are positive.
Therefore I have toe out at the front and toe in at the rear.
The standard suspension specification from David here, suggests this is correct.
With poly bushed compliance setup's (as mine) Rob Bell's site at http://www.mgf.ultimatemg.com/ shows best settings are toe in +0°5' per tyre front and rear. This is also Dieter's view, as Adam shows above.

Looks like I had better get the fronts moved to toe in to suit the stiffer rear compliance components. With the current setup the car seems to wander a bit at motorway speeds.

For reference I run 15" T1-R Toyos (all four are new new) and Gaz shocks set to 4 front and 6 rear. I maintain 365mm ride height on both sides at the front (MGF so Hydrolastic of course).

I may be reading your settings wrong but it looks to me as if you have toe in front; toe out rear.

Hi I had my TF 4 wheels alignment done but they also did caster and camber which were not right but you can not alter these so what is the point in it
