Had a feeling the steering on my ex-GDI Plus 4 (now turboed Plus 4 Plus) Possum was a bit heavy. Greased the front suspension at even more frequent intervals, even increased front tyre pressures a smidgin (this is a technical term).
Either the steering was still too heavy or my aged arms were getting weaker. Finally dug out my old Dunlop optical tracking gauge. Have to admit I'd not checked the tracking since the car was bought new in 2014, 10K miles ago. The specs say toe-in should be
0 (ie parallel) to 3.2mm. I measured toe in at a good 5mm. Re-zeroed the gauge and checked again. Same result. Presumably set like this by the factory since I had not knowingly hit any potholes/kerbs. Since some of the racers even dial in a smidgin of toe OUT, to cut understeer and aid turn-in, I decided to set Possum at 0mm -- exactly parallel. Just driven a 40-mile test and the difference is marked. Steering feels much less heavy, car tracks well in a straight line but turns in much better. So, if your steering is heavy might be worth checking the tracking and go for a parallel setting.

Griffo, sounds a good result for you

FYI, just looked at my 'post roadtest tracking sign off' sheet that the MMC use and it shows Toe 1mm per side (doesn't quote in or out), Camber -0.5

Hi Jon,
That will be a total of 2mm. Within the spec limita of 0-3.2.
