A friend of mine gave me the following information, use at your own risk:
After seeing reports about front brake pad issues on track in a model 3 I decided to work on a solution. So here is what I came up with:
The front pads are almost identical to the 2003 Dodge Viper pads. I found two differences:
1. The Bosch aftermarket Viper pads are about 18 mm thick and the 1,000 mile Model 3 pads are about 16mm thick.
2. The metal backing plate is a little taller at the upper corners.
I installed aftermarket Bosh pads for the Viper on the outside pads for a test drive. They were almost too thick for the outside and I couldn’t fit them on the inside. They worked perfectly. At some point I will order performance pads.
I will probably buy the Yellowstuff EBC pads at some point since they spec 16mm thickness.
Other choices include Hawk pads that have 610 as the last three digits (0.61” is close to 16mm), your favorite brand and have some brake pad material removed by a professional, used pads from a Viper of the appropriate years.
The pencil in the picture points to where the metal backing isn’t as tall as the stock brake pads.
