Worried about additional weight?

We frequently get questions about the weight of our off-road brake systems compared to stock and aluminum systems. The fact is that this aspect of the brake system is important, but not really a significant factor.

Power loss/mass increase due to extra rotating weight is very small compared to the additional rotating mass of tires or heavy duty wheels. The rotors are very near the rotation center of the wheel and will have a negligible impact, especially compared to the tires. Power loss is generally felt as 1 HP per 7lbs.
