This is the Inner Wheel Lift for Assetto Corsa Touge. An extraordinary technique popularised by initial d that many drivers want to replicate. In this video, I’m going to be telling you all you need to know about the inner wheel lift, and at the end ill be showing you exactly how to do it. So, make sure you stay tuned, because you won’t want to miss out on this one.
So, what exactly is the inner wheel lift? An inner wheel lift essentially means floating a single inner tyre float above a gutter. It’s stated that Wheel lifting allows the driver to take a corner at higher speeds than usual, due to more weight being shifted to the rear tyres. But, as usual, there are a group of people that deny this, and would call inner wheel lifting anime make believe. So, let’s take a look at the actual physics behind wheel lifting, and make up our own minds about it.
Wheel lifting has been around for far longer than initial d has. And, even without gutters. In fact, we can see race cars as far back as the 1950s lifting their inside wheels. This wasn’t done by accident, either. Many race cars and even some street cars are intentionally set up to lift up their inside tyres. From F1 cars, to trophy trucks and even that riced out honda civic that blasts past your house at 3am every morning. So, why do they do this? Surely less tyre contact with the tarmac means less grip right? Well, not quite.
In fact, lifting a front tyre can actually increase traction. Let me explain;
When you corner in a car, it practically wedges itself into a corner. The weight of the car is shifted towards the outside due to g force, and as a result, your outside tyres are putting far more work in than the insides. However, the car will want to distribute grip equally to all four tyres - and as a result, we actually waste grip on the insides, simply because it isn’t needed there.
So, that’s why racing teams across the globe want their inside tyres to lift. Simply because it allows the car to send more grip to the outside tyres, which aids with cornering, and allows the driver to do so at higher speeds . But, this does come with one downside. With only two tyres putting in 95% of the work, the car also becomes more unstable. It’s far easier to go over the limit of grip, making the car much more unstable.
It goes without saying that pretty much all cars that are raced on the touge are also street cars. They didn’t have teams of mechanics behind them, or suspension systems that cost an arm and a leg. The cars we race on the touge have to be driveable on the day to day. So, naturally, their suspensions are relatively soft compared to the cars we were just talking about. Lifting a street suspension - or even coil overs is next to impossible. So, the question is; how do we lift a wheel without actually lifting a wheel? The answer is of course gutters. Not only do gutters allow us to load our outside tyres with more grip, but they also allow us to do it in such away that doesn’t sacrifice too much stability - simply because we aren’t lifting our wheel mechanically. In fact, we still maintain all the characteristics of a soft suspension. We’re just not letting our car deliver grip to our inside tyre.
The touge that I chose for the inner wheel lift is nagao by euro and kozzren. It has massive, open gutters that are perfect for this technique. When I first started attempting the inner wheel lift, I had a lot of trouble. I was actually trying to do it on a full grip run - which is where the issue lies. I found it hard to keep up enough momentum for the wheel to actually float, whilst also staying on the racing line. You need to already be near the limit of grip for the lateral g forces to be so high that your car doesnt just fall into the gutter. Another factor that played into this was the ability to get just one wheel over the gutter whilst gripping. It was surprisingly hard, and I found that you needed to be oversteering - or drifting if you want to do the inner wheel lift.
