    Leave swaybars stock. Softer springs. Make sure whats there has good bushes and works appropriately. Not too much caster, maybe 3.4 degrees. Also, perhaps about 2.5-3 degrees negative camber, and you will still scrub the outer edge of the tyre if you drive it hard enough. Zero toe if your steering rack is perfect, otherwise if it has some play, toe it in a tiny bit. I find height is critical, as in the right ride height front to rear. It changes the handling a lot. Lower the rear too much and it will create understeer, raise it too much and you can create oversteer issues. Pinion angle can be tuned, and there is a sweet spot for good grip. I find it better for the cars balance to have an equal sized wheel and tyre on a car with as little power as a 4age ae86. It makes it a lot more predictable. With 8/9 combo and appropriate tyres you may find it hard to make the front steer right, it could tend to push the front through corners with more rear grip than front.

    Some good advice there indeed. We have done tyre heat testing at Mallala and 2.5 is pretty much perfect, we had a 3-4 degree difference across the whole tyre. As apposed to it previously having 5 degress and having a 20 degree spread.

    Thanks for the advice. I have got some softer springs and will be testing at Morgan Park in a couple of weeks. Im getting some help from Bruce McKenzie, twice NZ rally champ. He won both titles in a privately built AE86 beating the TRD NZ team and Possom Bourn too. We are giving the 4A a birthday in the near future too.

    The clip below isn't my best lap of the weekend, but it does show how it bounces about with the original setup.

    Was doing laps, not drift

    Always helps to get balance setup right first with just laps and on limit grip testing before seeing how the car feels to slide.

    Davey's car is far from an ideal circuit setup, have a look at what most of the ipra cars run camber wise, you'll find it's a lot more than 2.5 degrees
