Current RCRs:


- add 'driveshaft' to 7.3.c trans fitment allowance

- remove This bracing may not pass through the shock tower and must not form the upper mounting
point for an aftermarket SLA system as the SLA must still remain within the original shock
 from aix 5.12

- add any devices that can adj hp to be located in engine bay only, not in cockpit?

- change dyno requirements to 2 years if no changes

- update any trans and traction control to aix to go with new 5:1 rule

- SI 7.12 allow evap parts removal
