M-System

The intent of the M-System cover was to direct more air to the brake assembly to increase cooling.

An ideal maximal with respect to having empty intersection with a fixed m-system is prime.

They came with full M5 interior and the "throwing star" M-System II wheels, but did not have the Motorsport S38 engine nor the M-tech exterior kit fitted.

If S is any m-system in R, then a lemma essentially due to Krull shows that there exists an ideal of R maximal with respect to being disjoint from S, and moreover the ideal must be prime.

A nonempty subset S R is called an m-system if for any a and b in S, there exists r in R such that arb is in S. The following item can then be added to the list of equivalent conditions above:
