If I decided to put year 2000 wheels on my 98, would I have to make any adjustments to anything? or would it be a straight, no issue exchange? Would it affect the odometer by being a bigger wheel? like going from 15"s to 17"?

 

there should be no problem. the odometer effect depends on the tire size that is mounted onto the wheel, but unless you have a really big tire or really small tire, it shouldn't make much of a difference.

And you should lower your car, or it will be an off-road monster

 

doesnt Sound like a bad idea.........

 

the only way the odometer would be off is if the tire is bigger than stock. When i got my winter tiers i got a lower aspect ration (due to more tred) to keep my spdo working properly.

 

I thought starting in 1997 the wheel size went from 15" to 16". Are you sure you aren't on 16s?
