If you are moving up from a desk clamp or a folding tube stand, both the ASR 1 and the ASR 3 ($522.49 net with code SIMRACINGNATION5) give you real T-slot aluminum rigidity. While the ASR 1 keeps costs as low as possible for entry direct drive setups, the ASR 3 is the clear winner for racers who plan to upgrade to 15 Nm or 20 Nm wheelbases.
Frame Stiffness and Profile Dimensions
The ASR 1 uses a 3-inch by 1.5-inch base frame paired with lighter vertical uprights designed for entry-to-mid direct drive wheelbases up to 10–12 Nm. Stepping up to the ASR 3 ($522.49 net) reinforces the steering uprights and mounting brackets so the frame handles up to 20 Nm of sustained torque without flex.
