Senner Tuning is a KW performance partner and has developed an accessory package for the Toyota GR Yaris. But don’t worry – the “Race Edition” package of Senner Tuning isn’t a rallye-program. It is a package for everyday life – or to put it another way “everyday drive” – with an included parts certificate.
The Japanese automotive manufacturer Toyota is still producing affordable vehicles with combustion engines. Nevertheless, Toyota is a pioneer in its hybrid-electric cars (Toyota Prius since 1997) and cars with hydrogen propulsion (Toyota Mirau since 2014). It is safe to say that there truly is something for everyone in Toyota’s product range.
It is common sense that the three-cylinder turbo engine has enormous power. Depending on the market and emission standard, the G16E-GTS has a standard performance of 261 HP (Europe) or 272 HP (Japan).
Our KW performance partner Senner Tuning has more than 20 years of experience regarding increases in performance. With help of diagram optimization and Wagner intercooler, the standard version of the GR Yaris “Race Edition” can increase up to 351 HP.
An HJS downpipe with included 300-cell-ECE-sport-kat and Milltek exhaust system are aboard as well as a KW suspension. To specify, a KW V3 coilover.
To be honest, we have different suspensions for the Toyota GR Yaris in petto. In the WRC every Toyota GR Yaris Rally1 is equipped with motorsport suspensions from our colleagues of Reiger Suspension. But the “Race Edition” by Senner Tuning addresses all GR-Yaris drivers who like to use their Turbo Toyota daily.

Our KW coilover suspensions – such as the KW V3 in the “street performance” category – differ from our KW clubsport coilover suspensions. The KW coilovers in the street performance category are specially designed for daily street usage.
Let’s get a little more into detail to make sure you find the perfect suspension for your personal demand:
If your need is to drive your GR Yaris on a daily basis or in your private life the KW V3 coilovers are the right product for you.
If the popular Nordschleife at the Nurburgring is your second home and your GR Yaris is very close to serial production, then the KW V4 clubsport might be the right choice for your car.
The difference between both coilovers is the following: With the KW V3 “only” the low-speed compression and rebound forces can be adjusted separately. With the KW V4 clubsport (KW clubsport 3-way) coilover suspension the high-speed and low-speed compression and low-speed rebound forces can be adjusted separately.

The interior of a KW clubsport coilover suspension and the piston rod, the seal- and guiding package, valves, pretension springs, and main springs are developed especially for racing cars. They are built for higher physical forces.
If you’re driving your Toyota on a daily basis those physical forces won’t apply to your car. Not only do the settings of the valve technology differ from each other but also the spring rates of the components in the valves.
Light-alloy Kiwami Work wheels in the dimensions 9.5 x 18 inches (245/35R18 Michelin Pilot Sport Cup 2) are an inherent part of the Senner Tuning “Race Edition” for the Toyota GR Yaris.
It’s up to you whether you go for KW V3 or the KW V4 clubsport coilovers. Both coilover kits come with a parts certificate and enable continuous lowering of 25 to 45 millimeters. If desired, the complete “Race Edition” for the Toyota GR Yaris can be purchased directly at Senner Tuning with TÜV documents, professional installation, and performance enhancement
In addition, there is a coilover-service our certified and professional KW Performance retail partners offer. Manufacturer warranty included.
