This fully plug&play kit raises the accelerator pedal by 17mm and moves it to the left by 20mm. The purpose of this modification allows you to use the "Double-clutching" and "heel and toe" techniques quickly and easily.


  1. The reduced distance between the accelerator and the brake allows shorter and therefore faster movements between the accelerator and the brake.
  2. During fast gear shiftings, we have found some jamming with the stock gearbox, that generates "displaces" and/or "scratches", especially between second and third gear. All this can generate sudden wear of the synchronisers, gearbox failure and, at worst, unwanted "over-revving" which is not good for the distribution.
    In sporty driving, under acceleration, the double-clutching technique is generally used to remedy these problems (Toyota, aware of this problem, has inserted an electronic system that can be activated for automatic double- clutching device). This electronic aid helps to limit these problems, but manual management can be, if done well, much more efficient and precise.
    In deceleration, on the other hand, the " heel and toe " technique is used, this allows for better synchronization of shifting, helping the transmission synchronizers to obtain faster, more precise downshifts free from scratching and jamming.
  3. "Heel and toe" is essentially a driving technique that combines braking with downshifting. You usually use it before entering a corner to maximize your speed while keeping the car's dynamics at much higher safe levels. The goal of this technique is to uniformly match the speed of the engine to that of the wheels. When the clutch pedal is released, the engine acts as a brake and, before the transmission starts rotating the engine, the latter risks slowing down the driving wheels so much as to undermine the grip of the tire and in any case it creates a load transfer of the vehicle capable of destabilizing it.
    In the case of front-wheel drive, the load transfer can be so intense as to lighten the rear axle until the tire grip is nullified, with the result of putting the vehicle into a skid and making it spin on itself or, in the case of limited grip , causing the front wheels to lose traction and the resulting trajectory is understeer.
    On the other hand, a rear-wheel drive vehicle will always oversteer but even in this case it will be difficult to control.
    An all-wheel drive vehicle, such as the case with the YARIS, will do a mix of the two, based on the traction and grip distribution of each tyre.
