Default Wheel Spacers & Solo II

I'm running 225/50-16 on stock rims and am wondering what size can I go on with wheel spacers while still staying legal for Solo II events?

For stock class. For classes that allow more modifications, offset is unlimited or limited only by total track width.

My math is not so great but if .25" is equal to 1/4" and there are 10mm to an inch than I will need to purchase a wheel spacer that is around 2mm-2.5mm am I correct. I'm asking this because they only sell wheel spacers in mm.

Depends on car, driver, tires and car set up.

My car is a WRX Wagon and I'm looking to rid it of as much understeer as possible while still staying legal for Solo II runs. The driver (myself) could always use improvement in the art of driving and handling a car but that my friend may take some time.

Not sure that 1/4" wheel spacers are really going to buy you anything handling-wise. You're probably better off trying to figure out how to get as much negative camber up front as possible.

increasing the front track will add more grip to the front.

not a bad idea really.

can't do much with front camber in stock

but naturally be sure to max out the front camber as well!

I heard there were downsides to spacers - like bearing wear. Does anyone know if that's a real issue?

Also, the spacers I've seen are flat, so I'm guessing the wheel is just supported by the studs. Are there spacers with the hub ring (hub centric)???

yes as the wheel moves out you get more force on the wheel bearings.

if you just use them to autocross on it won't be a big deal
