As you look at Spyder wheel options, you'll see wheels ranging in diameter from 15"-18". Although the Spyder can run 15", 16", 17" and 18" wheels, staying with a 15" wheel allows for broader tire selection and less rotational weight.
OFFSET AND WIDTH
The earlier (2000-2002) Spyders ran 15x6 45 mm offset (ET 45) front wheels and 15x6.5 ET 45 rear wheels. The lower the offset, the further "out" toward the fender the wheel moves. While some drivers might prefer the wider stance of lower offset wheels, our goal here is to maintain the car's original steering feel and tracking. So try and stay with wheels that are close (within 6 mm) of the Original Equipment wheel's 45 mm offset. This will minimize scrub radius change, while helping to preserve the car's go-kart handling and steering feel.
Although later (2003-2005) Spyders have 16" rears as Original Equipment, you can change to 15" rear wheels. Your wheel choice might not be available in a wider rear size, however it's okay to run the same wheel width front and back. The key to maintaining the car's overall handling balance is staying with the tire suggestions covered in detail at "Alternative Tire Sizes for Your MR2 Spyder."
TIRE & WHEEL PACKAGE
In addition to the above considerations, find a wheel that meets your style preferences and a wheel finish that works well with your Spyder's body color. Go with the style and finish that you like.
Personally, I am a fan of the 15x6.5 ET 42 Enkei Performance Series GT7 in either hyper silver or black on 185/55R15 front and 205/50R15 rear Yokohama S.drive tires.
