Best Logitech G29 Wheel Mods: Buyer’s Guide

A Logitech G29, G920 or G923 is a fun way into sim racing, but the force feedback is simple and light, and after a while you notice how little it tells you about the grip. The rim is the round part you hold, and it bolts to the wheel’s hub, so a rim mod changes what’s in your hands. A brake mod changes how the pedal reads your foot, and neither of them touches the motor.

I’ve had a G923 kicking around for ages, and I keep it mostly for comparison and a little bit for nostalgia. It isn’t direct drive and it’s not cutting edge, but for what it is, and for how old it is, it’s astonishingly good. Logitech were probably one of the most influential manufacturers in the early days of sim racing.

My G923 is the PlayStation version, and Acelith shapes most of its Logitech rims around either the PlayStation or the Xbox layout, so the version decides which rim you buy. Below I’ve gone through Acelith’s replacement rims for the Logitech wheels, how they fit, the pedal and brake mods, and the point where it makes more sense to buy a new base than to keep modding the one you’ve got.

What does a stock Logitech wheel lack?

Logitech rates the G29, the G920 and the G923 at 2.3 Nm, with two motors driving the wheel through helical gearing. The G923 adds TRUEFORCE and what Logitech calls a “pressure-sensitive” brake. Behind the rim, the G29 has stainless steel paddles.

With the Logitech wheel, the FFB (force feedback) is very simple and not very strong. So on track, it’s hard to tell where the grip levels are, which makes it difficult to tell what the limit of grip feels like. This is especially true when you’re having an accident, it’s like you don’t get the information fast enough to be able to respond in time. The G29 can be a very fun bit of entry level kit, but I get the sense that the faster drivers are doing it from memory and pure practice alone, rather than responding to a dynamically changing car, circuit and overall level of grip.

The G920 is the Xbox model, and the G923 comes in a PlayStation version and an Xbox version, so check which one you’ve got before you shop. Acelith’s stock-sized rims are 28 cm across, and the rims below run from the 27 cm F27 to the 29.8 cm Morph.

Acelith Ace Morph G30

The Ace Morph G30 is Acelith’s modular rim, and it’s the one to look at if you drive a bit of everything. There’s one central core, and straight or curved modules bolt on at the top and the bottom, which gives you nine or more configurations from the same rim. It’s 29.8 cm across, built on a 5 mm anodised aluminium plate, and it weighs between 600 and 1000 g depending on how you’ve put it together.

The grips are polyurethane with a synthetic leather or suede finish, although the suede version is sold out at the moment. Acelith lists the Morph for the G29, both versions of the G923 and the G920, with the adapter and the hex keys in the box. On an Xbox wheel you can add Acelith’s gap filler for the space round the Xbox button, and there are optional 3D-printed shape modules for the upper and lower ends. Acelith said the handles come off in 30 seconds when its founder showed an early version on Kireth’s YouTube channel.

Formula rims: F27 and OP Formula

The F27 is Acelith’s formula-style rim, and at 27 cm it’s a little smaller than the 28 cm stock-sized rims. It’s a laser-cut steel plate painted black, with hard plastic handles finished in soft-touch paint, and the L2, L3, R2 and R3 buttons come with it. Acelith optimises it for the PlayStation layout, so on an Xbox G923 the hole for the home button is a little larger than it needs to be. There’s a separate Xbox version of the F27 as well.

The F27 is heavier than the stock rim, and on a 2.3 Nm motor the extra weight could dull the force feedback. Danny Lee tried Acelith’s mods on his YouTube channel (Acelith sent him the parts) and weighed the F27 at 615 g, against 468 g for the stock rim. He couldn’t feel any dulling at all. The OP Formula rim is the open-wheel option at the stock size of 28 cm, with a carbon-look vinyl over the steel plate, and it fits the G29 and the PlayStation G923.

GT3 rims: L-Style and Bent L-Style

The L-Style GT3 rim is a 28 cm GT shape, with soft-touch-paint handles on a steel plate, and it’s made for the G29 and the G923. The Bent L-Style has the same shape on a bent plate, where the L-Style’s plate is flat. The bent one mounts like the original rim, without the adapter, but it only comes in the PlayStation version.

If you’re into rally, the Morph is the way to get a round wheel on a Logitech, with the curved modules fitted top and bottom. Acelith does make dedicated rally wheels, but they’re PC wheels that need a quick release, so they won’t go on a G29, G920 or G923.

Fitting an Acelith rim (and the paddles)

Most of Acelith’s Logitech rims fit with an adapter, and it comes in the kit, so you’d only buy one on its own as a spare. For the F27 and the L-Style rims you’ll need H2, H2.5 and H4 Allen keys and a small Phillips screwdriver, and Acelith sells a tool kit with all four in it if you don’t have them to hand. Acelith has an installation video, and it’s worth watching the whole thing before you pick up a key. Danny Lee’s fitting took about an hour.

Acelith’s magnetic shifter goes on the stock paddles separately, with a 2 mm hex key, and you don’t have to take the hub apart for it. Danny Lee found it made the paddles feel much firmer, with a distinct on and off.

If you’re in the UK, Acelith only ships to you for parcels worth more than £135, which means a single rim won’t ship on its own, and the courier collects customs on top.

Pedal and brake mods

Obviously, you’ll want to ditch the pedals that come with the G29. In 2020 I ran Heusinkveld Sprints, but on a lower budget the Fanatec pedals were excellent. The G923’s own pedals are my budget pick, though, especially under a desk, because the base is heavy enough not to slip on the floor.

The AXC TrueBrake, made by AXC-Sim in England, fits the G25, G27, G29, G920 and G923 pedals. It replaces the brake’s position sensor with a linear sensor inside a sprung piston, so the pedal reads more like how hard you’re pressing than how far it has moved. AXC calls it a potentiometer-based load cell.

A strain-gauge load cell measures the force on the brake directly, and small makers sell load cell conversion kits for the Logitech pedals as well. To replace the whole set, start with our guide to sim racing pedals.

When to stop modding and upgrade the base

If you don’t have 10 hours a day to practise (like me!), you’re probably never going to improve past a certain point with a G29. If you want to feel the wheel as it should in a real car, you need proper force feedback from a more serious wheel. No rim or pedal mod changes the 2.3 Nm motor.

Direct drive means the wheel sits on the motor shaft, with no gears in between. For PC, the Moza R5 bundle is a 5.5 Nm direct drive base with a wheel and pedals in the box. Our guide to direct drive wheels covers the rest of the field. If you race on PlayStation, the Fanatec CSL DD won’t work, but Logitech’s own RS50 will, and it comes in Xbox and PC versions too. Acelith also makes rims for the RS50’s hub, so the modding doesn’t have to stop when you move up.

The bottom line

The Morph is the rim to start with if you race more than one kind of car, while the F27 and the OP Formula are built for open-wheelers and the L-Style for GT cars.

When you want to feel where the grip levels are, and the Logitech can’t tell you, that’s the point to buy a new base. Until then, there’s a lot of fun left in a Logitech with a new rim and Acelith’s magnetic shifter fitted.
