I use wheel wax between wheel cleanings

I ran the stock OEM sports, and the EBC yellows so far on a far amount of HDPE's last year. About 20,000 street miles plus 6 days on each set... not bad. I like the EBC yellows and would use them again. They work great on the street. A little bit more initial bite than needed for regular daily driving/stop-n-go, but it's bearable. Some slight noise. But they stop good combined with ATE 200.
