If you own an older Thrustmaster – a T300, TX, T-GT or TS-PC – you do not have to put up with that mushy stock rim and vague paddle feel. A whole aftermarket scene has grown up around these wheels, and the good news is that the mods that make the most difference are cheap. Today’s guide runs through the upgrades worth doing, roughly what they cost, and an important catch: is there is a point where you should stop modding and just buy a direct drive base instead?

What’s worth modding on a Thrustmaster (and what isn’t)
The older belt-driven Thrustmaster wheels have one big weakness and it is not the force feedback – the belt feel is decent. It’s everything you touch. The stock round rim feels cheap, the paddles are soft and springy, and the pedals have a brake that squashes rather than resists. Those are precisely the problems a good mod fixes.
The rule of thumb is simple: spend money on the parts your hands and feet touch, and keep the total sensible. A £15 magnetic shifter mod, a £20 brake insert and a £60 formula rim make an old T300 feel far better for well under £100. What is not worth doing is pouring £150 or more into a belt base that is fundamentally obsolete-generation – past that point the money is better spent on a modern direct drive wheel, which we come back to at the end.

One thing to know before you buy anything: most of these mods are made for specific Thrustmaster models, so check the exact fit for your base. A rim cut for a T300 button box will not bolt onto a TS-PC without the right version. With that out of the way, here are the mods worth doing.
Formula and GT3 rims: the biggest single upgrade
Swapping the stock circular rim for an aftermarket one is the single biggest change you can make to how an old Thrustmaster looks and feels. The drop-in rims from makers like Acelith bolt straight onto your existing Thrustmaster button box using the stock screws, so there is no quick-release or hub to buy – you keep all your buttons and paddles, you just get a proper wheel to hold. They come in two broad shapes: a flat-bottomed formula rim for single-seaters and open-wheelers, and a rounded GT3 or “Mc-style” rim for GT and endurance cars.
For a T300 (the most common base to mod), you have the widest choice – formula rims and GT3 rims are both available, usually in the £55 to £70 bracket depending on the grip finish. Which shape you want comes down to what you race: a formula rim if you spend your time in F1 or open-wheelers, a round GT3 rim if you live in Assetto Corsa Competizione or Le Mans Ultimate. Neither needs any wiring or soldering – it is a screwdriver job.
The T-GT and TS-PC bases are catered for too, though the choice is narrower – a formula rim for the T-GT is the pick most owners go for. If your base is a T-GT rather than a T300, look for the version cut specifically for it.
Magnetic paddle shifters: the cheapest worthwhile mod
The stock Thrustmaster paddles use a soft spring that gives a slightly mushy, imprecise shift. A magnetic shifter mod replaces that springy feel with a crisp, tactile click – small brackets holding neodymium magnets that snap the paddle back the instant you pull it. It is the mod that makes the biggest difference for the least money, and once you have felt it you will not want to go back.

There is nothing to be scared of fitting one. No soldering, no wiring – most kits either stick on with heavy-duty double-sided tape or use existing screw holes on the wheel casing. Pre-made kits sell for around £10 to £25, and if you have access to a 3D printer you can print the brackets yourself for pennies and just buy the magnets. For your first mod, this is where to start.
Quick-release adapters: faster rim swaps
Older Thrustmaster bases hold the wheel on with a fiddly threaded plastic collar and a screw, which is fine if you never change rims and a bit problematic if you do. Aftermarket 70mm pcd quick-release mods let you pop a rim off and on in seconds, which is handy if you own both a formula and a GT rim and switch between them depending on what you are racing. Expect to pay £20 to £50 for one.

There is a second, different quick-release worth knowing about. If you upgrade to one of Thrustmaster’s newer direct drive bases – the T598 or T818 – and you want to keep using your old ecosystem rims, Thrustmaster sells an official quick-release adapter (around £30) that makes those rims tool-less on the new base. That is the bridge between the old world and the new one. Our quick-release hubs guide covers how these systems work across brands.
Pedal mods: better brake feel for less
The weak point of the stock Thrustmaster pedals is the brake – it moves too far and squashes softly rather than building resistance, which makes it hard to brake consistently. The cheap fix is a brake mod: a firm rubber or elastomer insert that slides in behind the brake pedal to give a stiffer, shorter, more progressive feel that is far closer to a real brake. These sell for around £15 to £30 and take a couple of minutes to fit. For the money, it is one of the most worthwhile pedal upgrades going.

If you want a proper step up rather than a mod, the established path is a load cell pedal set, which measures how hard you press rather than how far – the single biggest upgrade to braking consistency you can make. That is a bigger spend and a topic in itself; our sim racing pedals guide runs through the load cell options and where they fit.
When to stop modding and buy a T598 instead
Cheap quality-of-life mods on an old Thrustmaster are excellent value – a magnetic shifter, a brake insert and a rim will make a T300 or TX feel far nicer to use for under £100, and that is money well spent if you are happy with the wheel otherwise. Where it stops making sense is heavy spending. Once you are looking at £150 or more in mods on a belt base, you are polishing last-generation hardware.

The reason is the Thrustmaster T598. At around £450 it brought real direct drive – no belt, no lag, force straight from the motor – down to a price that used to buy a belt wheel. So if your old base is on its way out, or you find yourself tempted by a big-ticket mod, the smarter move in 2026 is usually to sell the old wheel and put the money towards a T598 (or an entry direct drive base from Moza or Fanatec). Our Thrustmaster wheels buyer’s guide lays out where the T598 sits in the range and what else is worth considering.
Mod the parts your hands and feet touch, keep the total sensible, and know when to graduate to direct drive. If you are still choosing a base, start with the wheels guide; if it is the pedals letting you down, the pedals guide is the place to go next.
