Autocross Setup - Right Wheel/Rims
Looking at setting up for autocross/solo II and think I want to run 245/40/17s all round.
From the sticky on wheel fitment guide, for 245 tires, the minimum offset is +63 for the front rim.
Does this mean that +65 would work, but +58 wouldn't. Or, is it the reverse.
Guess I'm confuse on how offset works.

What size rim are we going to be using? Some people like non-staggered and some don't,I'd check it out before doing anything.Might not like it 
I've read that to take full advantage of the non-staggered set up,you have to the driving skills to induce over/understeer at will.Modding can be a can of worms,you do one thing and then you have to do another to compensate for it.

+63 minimum means +63 would work, and +58 (which is LESS than 63, the MINIMUM) will likely rub.
Fitment for a big brake kit is a different question.
If you're setting up for autoX, the first question is what class you intend to run. If stock, you'll have to run stock wheel widths and offsets within ~5mm of stock.
Stock, you'd likely want to run 225/45 fronts and 255/40-17 rears.
(although some run 245/40 fronts and 275/40 rears which are way outside the recommended size window for stock 7" and 8.5" wheels!).
If not stock, 245/40-17s up front with 255/40-17 rears, or 255's all around, or maybe 275/40 rears.

Also forgot to mention ... the alignment would be a bit different ... probably -2 camber front & rear. And, 1/8 to 1/4 toe on the rear.
Think this kind of throws the tables off.
Doing a little research, the rims should probably be 17x8.5 with an offset of +50.
Am I on the right track??
(Note: Class would be the new STR -- right now at least, don't think the rules care about offset ... just can't be more than 8.5 on the rim width.)

Doing a little research, the rims should probably be 15x8.5 with an offset of +50.
