A Simucube wheelbase will happily expose every weak point in a cockpit. The good news: mounting Simucube cleanly is straightforward once you understand the common mount styles and the bolt patterns people search for.
This guide focuses on practical compatibility: mounting options, what bolt pattern information matters, and how to choose SIMGASM parts that make installation and future upgrades easier.
Mounting styles you’ll see for Simucube
1) Bottom mount via a mounting bracket
Many cockpits use a bottom mount “wheel deck” style. Simucube also offers a dedicated mounting bracket (“Simucube Mount”) that converts the wheelbase to a bottom-mount pattern.
Common drilling pattern you’ll see referenced: the Simucube Mount uses a 78.4 mm × 66 mm hole pattern. This is useful because lots of third-party wheel decks support that spacing, or you can drill to match.
2) Front mount / face mount (stiff and clean)
Front mounting is often the cleanest solution on an aluminium profile rig because it supports the wheelbase close to the load path. Less leverage means less flex.
3) Side mount (less common, but sometimes used)
Side mounts can work if the bracket design is robust. The key is avoiding “long levers” that let the base twist when you hit kerbs.
What matters more than the exact bolt spacing
- Load path: the shorter and more direct the support, the more stable the steering will feel.
- Wheel deck thickness and bracing: thin plates can resonate or twist.
- Fastener quality: use the correct bolt length and washers, and re-torque after a few sessions.
A simple Simucube mounting checklist
- Decide the mount style (front mount vs bottom mount). Front mount is usually the most rigid on profile rigs.
- Confirm bolt spacing using the manufacturer’s drawings or drilling templates (don’t guess).
- Plan cable routing before tightening everything (USB, power, wheel, any hubs).
- Test for flex by applying torque with your hands: if you can twist the mount, the base will twist it harder.
- Re-torque after break-in once everything has “settled”.
How to build a Simucube-ready cockpit with SIMGASM
The goal is not a “tank”. The goal is a cockpit that stays predictable under load, so you can run lower filters and keep more detail.
SIMGASM cockpit recommendations for Simucube
- Sport (best all-round): SIMGASM Sport cockpit (C120) for stiffness, a large footprint and clean routing.
- Pro (maximum rigidity): SIMGASM Pro cockpit (C160) if you want maximum headroom (high torque, motion, heavy pedals).
SIMGASM mounting parts that make life easier
- Wheel mount foundation: wheel mount base set
- Front wheel mount option: front wheel mount (ideal when you want a stiff, direct support path)
- Bottom mount option: bottom wheel mount (useful when your bracket/deck design expects a bottom pattern)
Monitor stability: don’t let the screen wobble
If you upgrade to Simucube and suddenly think “the wheel feels harsh”, sometimes it’s not the wheel. It’s visual instability. A screen that shakes makes every kerb feel more violent.
- Triples: a freestanding monitor stand keeps your screens stable even if the cockpit moves.
