ok, so because these are about 1" larger in the total diameter I'll be going faster then the reading on the dash.
Bernie, thanks. I do have both set's (tapered nut vs flat) as my bro-in-law gave them to me. The ones I have from my car and the one's from the Toyota. I would guess that with both being Japanese made cars maybe they cut some costs by using the same rotors spec's from time to time... I did check the depth of the wheel on both (on the car and the new ones) and both run at 6" of space from the back where the wheel meets the spindle and the edge of the wheel so the wheel sticking out or tucked in should not be an issue. The gap around the calipers looks to be a decent gap. I guess to tell that I have to take a wheel off and try one of the new ones to know for sure. My concern was the speed'o as i can buy new wheels and put these tires on them... Thanks again all.
