Hi all - just picked up a nice stock '03 V 70 wagon, and have a naive question perhaps...it has 15" rims. I would like to get the car a bit higher off the ground but don't want to compromise gas mileage or strain the motor. I do see a bunch of V70's with different rim sizes, but these tend to be the Turbo or XC models - mine is the base 2.4, which I bought intentionally for the good mileage. Any thoughts?

Thanks
