I've done numerous searches on here, but not found 100% confirmation of what I'm doing with upgraded wheels and tires. Hopefully someone can clarify/confirm I'm ok on this.

I have a '99 Base Boxster with factory 17" wheels. I just bought a set of used 18" wheels from a 2007 Boxster S. These wheels are shown as:

F = 18x8J ET57
R = 18x9J ET43

I looked on TireRack and they recommend this exact spec for my Boxster as optional wheels, and recommended tires as:

F = 225/40ZR18
R = 265/35ZR18

I'm trying to make sure these are going to fit without any rubbing or use of spacers, etc., and not 100% sure how to be sure. I'm relying on TireRack being correct in their recommendation, but thought before I head to the tire shop to get them installed, I would double check here to be sure I'm okay on this.

Thanks in advance for any help!
