Default Going with 18's...few questions

I'm putting some 18" rota sub zero's on my 2001 rs-t. I got the nitto 215/35/zr18 nt450 for the rubber. How much slower is my car going to go? Also...How much smaller is the overall diameter from the stock diameter.

Yeah....Definitely slower than before. Atleast it looks much better now. I'll just buy a boost controller to make up the difference in speed.

Not slower if you get chrome. Shiny things are good for an extra 10hp per wheel.

Why does it become slower? More rotating mass?

Yup. It also moves a higher percentage of the weight away from the center of the wheel. The further the wheel rim moves away from the center, the bigger effect its weight will have.

Where did you come up with that size? It's a full inch shorter than the stock tires.

215/45/18 will almost certainly rub, though. My guess would be that not too many tires are available in 215/40/18. So, that only leaves 215/35/18.
