This may of been asked and it may of been asked 100x, but in my basic searching I cannot find much info.

I was looking at getting 18" wheels. I did some AutoX and it is very easy to understeer with stock tires. Yes, I know it is the driver too. A lot of it is me pushing too hard and not driving well, but the stock tires don't help. I have only had understeer issues at the autox course(s) so far.

Would upgrading to 18x8/8.5/9/9.5 be a good upgrade, or should I stick to 17" wheels with new rubber, or 17" and get wider wheels?

I planned on getting 18x9.5 in the rear and 18x8 in the front to fill in the wheel gap and get better traction, but I don't want to wait to buy my wheels and the set I was looking at was more than I can spend right now.

I am making absolutely sure that the wheels weigh less than the 17s I have. I have a series.blue and from my research the wheels are 19-21lbs each. I am looking at the Motegi MR131 Traklites. They only come in 18x8. The price is nice, and the weight is even better! I don't necessarily like the wheels, but the price + weight are nice, so I figured I would go with that.

Is there any reason I shouldn't go with 18"? Is 17" > 18"? And lastly, should I go with something that is 18x9.5" in the rear, or will 18x8 (all around) do the trick?

Thanks in advance for the help, and sorry if this has been asked before. I couldn't find much.
