“Will my direct drive wheelbase fit on an RSeat rig?” is a very common question—and it’s also the wrong question. The better question is: which mounting style will give you the cleanest, most stable steering feel with your specific wheelbase?
Direct drive wheelbases can mount in three main ways:
- Bottom mount (bolts underneath the base)
- Front mount (bolts through a vertical front plate)
- Side mount (bolts through side brackets)
Quick answer
- If your wheelbase supports it, front mounting is often the most stable and clean solution.
- Bottom mounting is very common and works well if the plate is stiff and well supported.
- Side mounting can be excellent, especially for certain ecosystems—just make sure the side structure is rigid and you have cable clearance.
Mount style comparison (what you feel on track)
| Mount style | Why people like it | What to watch |
|---|---|---|
| Front mount | Very stable, great detail, clean alignment. | Requires a compatible base and a strong plate/upright support. |
| Bottom mount | Universal, simple, works with many wheelbases. | Plate stiffness matters; heavy rims increase leverage. |
| Side mount | Strong and tidy for some ecosystems. | Side brackets must not flex; check clearance for power/USB. |
RSeat rigs: what to check before mounting
- Wheel deck stiffness: wheel decks can be good, but high torque and heavy rims can expose micro-movement.
- Adjustment range: ensure you can get wheel height and tilt where you need it (especially if you change mount style).
- Clearance: some side-mount setups need extra room for power and USB connectors.
Common wheelbase ecosystems and mounting preferences
Different brands tend to “lean” into different mounting solutions. The exact patterns differ per model, so always check the manufacturer’s manual, but these are the typical trends:
- Simucube / Asetek class bases: often used with rigid front-mount or side-mount solutions for maximum stability.
- Fanatec direct drive: commonly bottom-mounted or side-mounted depending on the rig and mount kit.
- MOZA / Simagic / VRS: often paired with purpose-built mounts; many users prefer front-mount style rigidity when available.
The goal is always the same: keep the wheelbase supported so you don’t lose detail through micro flex.
Where aluminium profile rigs make mounting easier
On a profile rig, you’re not locked into one mount strategy. You can start with bottom mounting, then move to a front mount later without replacing the cockpit. That’s why many people cross-shop steel rigs and eventually move to profile when they change wheelbases or upgrade torque.
SIMGASM wheel mounting options
- SIMGASM front wheel mount for wheelbases that support front mounting
- SIMGASM bottom wheel mount for common bottom-mount patterns
- SIMGASM side wheel mount when side brackets match your ecosystem
- Wheel mount base set as a modular foundation
Tip: plan the whole front end, not just the wheelbase
Wheel mounting affects:
- monitor distance (a different mount can move the wheel forward/back)
- seat reach (you might need to slide the seat or adjust pedal distance)
- cable routing (front mounts can tidy cables, but only if routing is planned)
This is why builders who care about clean, flexible systems often choose rigs like SIMGASM Sport and SIMGASM Pro: you get the adjustability and routing structure to keep everything consistent.
FAQ
Can I drill extra holes in a wheel deck?
Sometimes, yes—but it can also reduce resale value and can introduce alignment problems if holes aren’t perfectly placed. If you’re regularly changing hardware, modular mounting options are usually a cleaner long-term solution.
Should I prioritize torque rating or mounting stiffness?
Both matter. Torque tells you how much force the base can output, but mounting stiffness determines how much of that detail reaches your hands.
