AutoX stock class, rear bar instead of front?

Oh yeah, there are some amazing drivers out there. At the same time, there are many average drivers out there who thinks they are good and tons of people who are into it a little too much. It's racing around a bunch of cones, big f-ing deal. Stock class is not really stock given most of the cars are trailered to and from the events, some of the shocks are so hard that they work almost like a spring. It's just weird rule/politics. I am happy running my local event, the days of sitting out in the sun for 2 hours for a stupid work assignment makes me want to puke. 5-10 minutes of run, 2 hours of work assignment? Screw that

I am not sure if your car is pushing on corner entry, middle exit or all three?

It's strange that you can change swaybars and not add an adjustable front upper arm for camber.


Here are some things you can do to free up the rear end:

If you are running any spacers on the rear rims, taking them off would free up the rear end a little.

If you have adjustable dampening, if you reduce the compression resistance a couple of clicks this will allow the rear to roll more causing an increased difference in vertical load on the rear tires...reducing rear grip mid corner and exit.

I am not sure what the limits are on your rear toe, but you could push to the limit and run either zero rear toe or even rear toe out if that is allowed, to free up the rear end.

You can also reduce the rear camber on the car to something like 1 degree to free up the rear end.


Certainly finding the optimal tire pressure for grip on the front and allowing the rear to be sub optimal will also give you more steering

To get some more steering on the front end:

You could start with zero toe or even some toe out. The Toe out will give you better initial turn in but depending the tires you run, will likely give you some more push in the middle of the corner due to the increased slip angle of the inside tire. Some tires like more or less slip angle to optimize their grip, so you will just need to experiment.

Also remember if you run toe out in the front and zero toe or toe out in the rear your car will feel very twitchy in a straight line. On the highway to the events you will need to be very careful as the crowns in the road will want to make the car change direction without warning on you. So be careful.

If you are allowed to change swaybars in your class, are you allowed to add some lowering springs? this would give you some much needed front camber due to the camber gain resulting from suspension compression. Since the rear has adjustments for camber you can reduce the rear camber to something like 1.5 to help with the steer.


Hopefully this helps...but in summary here's what you might want to start with

zero front toe
zero rear toe
rear camber: -1 deg
remove any rear spacers you might have on the hub
reduce rear compression resistance on rear shocks by a couple of clicks
Put your front sway bar on full soft or go back to the stock bar.

I did not comment on the rear sway bar...but as others have already pointed out, it can hurt your forward bite with the inside tire spinning especially with the stock lsd. Even the quaife diff will spin too much. I have not tried the 1.5 way or 2 way rear diffs, but they would likely fix that issue, but require more maintenance.

Cheers
