To get Stage 2 in Southwest Florida Beta, you need to rank up to Rank 2 first. One guide says the Stage 2 engine and other performance upgrades are locked behind Rank 2 or higher, and players typically unlock it by doing the in-game promotion/grind method until they hit that rank.

What to do

  1. Open the game and go to the job or promotion system used for ranking up.
  2. Keep completing promotions until you reach Rank 2.
  3. Once Rank 2 is unlocked, go back to the customization/shop menu and buy Stage 2 parts.

Faster method people mention

  • Some players use AFK promotion setups to keep ranking while away.
  • Others buy the 2x promo speed game pass to reach Rank 2 faster.

Important note

This is based on public forum/video info rather than an official game manual, so the exact steps can shift if the beta changes.

TL;DR: Get to Rank 2 , then Stage 2 becomes available in customization.
