I have a greater responsibility , I load my friend into a car that I built and maintain, I'm the last one to shake his hand and the last person he sees going into the beams, Its that trust that he has in me that I provided the best for him.
Yes , I have said that certain things are not nessasary , but were all performance enhancers that would offer no clear advantage and make the cost of racing go up. You cant garentee that a racer given the option of purchasing brake parts will source out the correct type and material and chose by cost alone, even if that means driving across town to save $2.00. That being said, Does the racer have to buy his disc brake setup from M/W or LAMB? NO, as they are a bit pricey, A set of Willwood's or Strange can be had, saving the racer a chunk of change and are the exact same system using the same materials and construction and one can expect the same life and performance levels
