CUSTOMER TESTIMONIALS

• Porterfield R4S are the best I've found. E.C. (Utah, USA)
• The porterfield R4S is a Carbon Kevlar pad, and more rotor friendly than a Carbon Metallic. It is a great vintage compound. I have found that under really aggressive track day driving these pads tendancy to overheat and "chunk" on the front (not good...). When I last used Porterfield, I had good luck with R4S rear and R4 front. GEO. S. (USA)
• I use Porterfield R4S on all wheels and like them. When it's quite cold out (towar freezing), don't expect to work to the limit on the first brake usuage, they do need some warm-up. As long as you're aware of this, they are very good. NA (California, USA)
