My old bolt on spacers were 8.5 lbs all 4, the estimate is 20lbs for every 1lbs of unsprung weight, so at 170lbs it should feel similar to having a buddy of yours riding along.

That's because you are.
This is so incorrect it is funny. 20lbs for every 1 lb?! The effect of unsprung weight adding some virtual larger "effective weight" to the car would vary with the location. The further away from the point of rotation the greater the effect. Spacers are right at the hub, 8.5lbs for all 4 will not produce a noticeable difference in acceleration. It's absurd that you think you can notice that.
