Default AutoX with wheel spacers?

Hey i am interested in getting wheel spacers for my after market 17X7 rims. I like to go out and do autox's every once in a while but wanted to see if wheel spacers are safe for aggressive driving, i looked around but could not find an answer
also, what would be widest spacers i could use on a 17X7 setup? I know there will be no exact answer to this because it depends on the wheel but generally speaking what would be the widest spacers i could use? I was thinking about doing 10MM rear and 5MM front??

1- If anything, you would want to run a larger spacer in the front, to widen the track and improve grip. A spacer in the rear will only increase understeer.

2- The biggest I'd run in an autocross without longer studs would be 3mm. You can run as big a spacer as you want if you get proper wheel studs. I've seen 25mm spacers being used in some circumstances.

The industry rule is that the distance of thread engagement must be at least as great as the outside diameter of the stud threads. You are asking for expensive trouble if you violate this rule, especially under high stress conditions such as cornering at the max.
