Installed 20mm H&R wheel spacers - not happy with performance

A lot of people say wheel spacers are such a small lightweight mod that they wouldn't noticeably slow a car down but it is added rotational weight and I swear it's not psychological. It might sound silly but I actually feel the car is a bit slower.

Does anyone else with 20mm spacers feel the same way?

I'm thinking of taking them off now and maybe going for something smaller like 10mm.

Unsprung weight, such as that from a heavy wheel/tire combo, is bad because the weight is concentrated 8-14" away from the center of the hub. The further away from the center of the hub, the greater the effect. Your spacer's weight is concentrated an inch or two away from the point of rotation. There is just no way that two spacers weighing that little are noticeable.
