If you’re searching for Advanced SimRacing ASR 1 vs ASR 3 vs ASR 4 vs ASR Pro, you’re not really comparing brands yet — you’re trying to pick the right stiffness and adjustability tier so your cockpit feels solid today and stays upgrade-friendly tomorrow.
This guide breaks down the current ASR lineup using the specs that matter in real life (profile size, footprint, adjustability and mount options), then maps each model to a comparable SIMGASM tier so you can choose faster.
The short version
- Entry wheels and lighter pedals: ASR 1 class rigs (and SIMGASM Hobby) are where “no flex” becomes affordable.
- Direct drive and load cell pedals: ASR 3 class rigs (and SIMGASM Club) are the sweet spot for most serious sim racers.
- High torque, more adjustability and cleaner builds: ASR 4 class rigs (and SIMGASM Sport).
- Motion, hydraulics, and endgame stability: ASR Pro / ASR 6 class rigs (and SIMGASM Pro).
ASR lineup at a glance
Advanced SimRacing publishes a clear “base composition” spec in inches. For quick comparison, the table below also shows the approximate metric equivalent (rounded).
| Model | Base profile | Rough metric equivalent | Footprint (published) | What it’s best at |
|---|---|---|---|---|
| ASR 1 | 1.5" x 1.5" | ~38 x 38 mm (40x40 class) | 50" x 22" | Budget entry, still rigid, upgrade-friendly wheel deck |
| ASR 3 | 3" x 1.5" | ~76 x 38 mm (80x40 class) | 50" x 22" | Direct drive + load cell “daily driver” rigs |
| ASR 4 | 4.5" x 1.5" | ~114 x 38 mm (120x40 class) | 50" x 22" | Higher torque stability + more adjustment range |
| ASR Pro | 6" x 1.5" base rails | ~152 x 38 mm (160x40 class) | Varies by configuration | Motion, hydraulics, “set it and forget it” stiffness |
What actually changes when the profile gets bigger
Most “8020 rigs” feel similar in a product photo. In practice, profile size changes three things you’ll notice immediately:
- Steering detail: less twist in the uprights means more micro-detail from your wheel instead of “rubber band” flex.
- Brake consistency: stiff pedal mounting reduces the tiny changes in pedal angle that cause inconsistent braking.
- Adjustment without compromise: stronger profiles let you run longer spans (for tall drivers, formula positions, or motion) without turning the cockpit into a tuning fork.
How SIMGASM tiers map to ASR models
If you like the ASR concept but want an easy way to choose a tier, SIMGASM keeps it simple:
- Hobby uses a 40x40 style profile as an entry simulator. It’s designed to be unusually strong for its price bracket and is available in multiple colors and personalization options.
- Club steps up to 80x40, which is a practical “fits almost everything” class for direct drive wheels and load cell pedals.
- Sport moves to a longer, wider chassis with 120x40 profiles and a stronger, more adjustable wheel mount. It also focuses on clean builds with pass‑through cable routing built into the frame.
- Pro is the flagship with 160x40 profiles and heavy steel platework for extreme forces, motion hardware and maximum adjustability.
Two setup tips that matter more than the brand name
- Pick your wheel mounting style first. Front mounts, side mounts, and bottom mounts all work — but they change adjustability and where the forces go. If you’re not sure yet, start with a flexible mount system like the SIMGASM wheelmount base set and add the correct plate (front mount, bottom mount, or Fanatec side mount) later.
- Separate monitors from the cockpit if you plan tactile or motion. A freestanding triple stand like SIMGASM Apex keeps your screens stable even if your rig is shaking.
Recommended SIMGASM gear
- SIMGASM Club (80x40) for most direct drive and load cell setups
- SIMGASM Sport (120x40) for more adjustability and cleaner cable routing
- SIMGASM Atlas GT seat for a supportive GT posture
- SIMGASM Apex freestanding triple monitor stand if you want monitors isolated from rig vibrations
- Shifter and handbrake mount for rally, drift or sequential setups
