FSAE_PUSH ROD SUSPENSION WITH U SHAPED ARB OR Z ARB (DUAL BLADE) SIMULATION
Hi, I hope you’re doing well. I wanted to ask if there are any existing models in the FSAE_BAJA library that can be adapted to simulate a pushrod suspension system with either a U-shaped anti-roll bar or a dual-blade (Z-bar) anti-roll bar, as I haven’t been able to locate one. If no such model exists, would it be possible…
