There is absolutely zero need (or advantage)  to use bevelled pinions or angled spurs in an anglewinder set up.......straight cut gears are completely fine, and used far more than "angled" gears.

If you look, you will see that most high end cars (Eurosport/ISRA/Wing/BSCRA etc.) use straight cut gears in anglewinder configurations, and have for years. These cars put far greater loads on the gears than anything you run.

The shallowish angle of your pod (12 degrees) coupled with the narrow spur face width,  and the tooth depth of .5 module gears, allows the spur to engage completely with the pinion.....even if significantly too much lash is present......so there is zero need/benefit to use anything other that straight cut gears in your cars.
Straight cut gears can also be used "hub in/hub out", and obviously in sidewinder set -ups, so while inconsequential, they are more versatile, if that is relevant to you.

Like all gearing, proper set-up ( lash) is critical, and on an anglewinder is is vital the spur does not move laterally on the axle throughout the race..this will either tighten or loosen the mesh/lash, depending on which way the spur is allowed to move.......neither is the hot tip for fast laps, worse, it can lead to a trackside repair.
