I give you the No S6 setup, tune and shift pattern to get the final sprint done and beat the event. The only real challenge is the final sprint. This car will otherwise easily beat every challenge thrown at it in Tempest 3 tier 3 at stage 5 only full fusions.
If you need BMW fusions, go buy the M235i and strip them. Also the M4 can be bought to strip as well.
This and the BMW Z4M40i are both excellent for the Tempest challenges.
