What to Upgrade First in Your Sim Racing Setup (Stop Guessing)

You have some money set aside. You have eleven browser tabs open. Four of them are wheelbases, three are pedals, and one is a monitor you cannot afford.

Welcome. Everyone has been here. Here is how to close ten of those tabs.

The two components that actually matter

Max Verstappen was asked what parts of a home simulator are worth spending money on. His answer was short: the brake pedal, and the wheelbase. Everything else, including the computer, came after.

Four world titles suggests he has thought about it.

Those two parts are the only things in your rig talking to your body in real time. Your eyes can be fooled by a decent screen. Your feet and hands cannot be fooled by anything.

Start with the brake pedal, not the wheel

Your bundle pedals almost certainly use a potentiometer, which measures how far the pedal moves. Your leg does not work like that. In a real car you brake by pressure, and your muscle memory is wired to force, not distance.

A load cell pedal measures pressure. Swap to one and trail braking stops being a guess, because 60kg of pressure feels like 60kg every single lap.

Here is the part that stings. A cheap potentiometer brake is the single biggest limit on lap-time consistency for most sim racers. Bigger than wheel torque. Bigger than screens. Brake five metres too early into every corner and you are giving away seconds a lap, and you will never find them by buying a fancier wheel.

A Sim Jack 200kg load cell set runs R8,000. That is less than half the price of most of the wheelbases in those open tabs, and it will do more for your lap times.

Then the wheelbase, sized properly

Direct drive is a genuine step change. Belt and gear-driven bases smear the detail. Direct drive puts the front tyres in your palms.

But bigger is not automatically better:

• 9Nm is plenty for road cars, GT3 and most club racing.
• 12Nm is the sweet spot for most people who race seriously.
• 18Nm earns its keep in formula and high-downforce cars.

The catch: torque you cannot mount properly is torque you cannot use. Newton’s third law does not care that this is a game. For every 18Nm the motor delivers, your frame has to resist 18Nm going the other way. If the wheel deck twists, the fine detail gets absorbed by the frame before it reaches your hands.

You paid for feel. The flex ate it.

The frame is boring and it comes first

Nobody photographs their frame. Everybody should buy a good one anyway.

If the pedal deck flexes under 80kg of braking, that deck becomes an unintended second spring, and your brake pressure stops being repeatable. That is the thing that quietly ruins consistency while you blame the pedals.

The order, then

1. Rigid frame. Everything else sits on it.
2. Load cell or hydraulic pedals.
3. Direct-drive wheelbase, matched to the frame.
4. Field of view. Triples, ultrawide or VR, once the PC can genuinely drive it.
5. Motion. Immersion, not pace. Worth it. Last.

The spiral that costs the most

Someone buys a bundle. Six months later they want more feedback, so a direct drive base arrives. The base twists the entry cockpit, so the cockpit goes. The new frame will not take the old pedal plate, so that goes too. Then triples land, the GPU cannot push them, and suddenly a new PC is in a budget that never planned for one.

Total spend: comfortably more than a properly spec’d build would have cost on day one. Plus a cupboard of orphaned parts and a partner who has stopped asking questions.

The fix is not spending more upfront. It is spending in the right order, on a frame that already has mounting points for the gear you will own in two years.

The honest answer for most people

If you are on a bundle right now and have one purchase in you, buy the pedals. If you have pedals and a wobbly desk, buy the frame. If you have both, then go and enjoy the wheelbase.

Nobody in the history of sim racing has regretted better brakes.
