Re: Posi-Quiets YES!
Yes, we all know how the front wheels will go almost black after a week of driving with the factory pads. After a single weekend of track time with the factory pads my rear wheels were almost black with brake dust - you can imagine what the fronts looked like! After installing the Posi-Quiets and then doing another track day, the front wheels were dirty but really not bad at all. And stopping power didn't appear to be compromised at all. Nice upgrade.
And Meguiar's All Wheel Cleaner is very good stuff indeed. I'd been using Meguiar's Wheel Brightener from the pro detailer line with the factory pads but no longer need to.
