The GS300 is an amazing platform in all its generations. Occasionally used in motor-sports, the GS300 has proven itself that it could be a performance vehicle. As a street car, it s refined and well mannered, comfortable to drive in and stylish with a bit of aggression in it s curves. Although the initial design was luxury and aggressive it was still designed as a street car and comfort was a priority with soft rubber bushings all around to absorb vibration. Through the years the soft rubber bushings deteriorate after constant flexing and vibration as well as being punished through weathering; this can cause them to tear and may seriously damage your engine and transmission. Megan Racing has developed a Harden Rubber motor mounts for the GS300. These reinforced mounts are perfect for enthusiast who is looking to get the most from their vehicles as these engine mounts will allow more energy to be transfered to the wheels instead of absorbing energy into the soft rubber.
