Point
・MAX IV GT for GRL10 is set with F Sport for street drive. First we did low-down. It’s adjutable lower bracket height adjustment type, so you can set the height as you want to within the available range. It will have stock stroke feeling of softness and adjusted where there is stiffness for the best driving experience. And we have divided weight to the spring and damper for the less rolling for steering and still feel natural to human feeling. Like the stock, it has full stroke so it has no uncomfortable push and the passenger will have a comfortable ride too. Also, we have set the matching with electronic device which provide more stability and less feeling of wrongness.
* When Changing the stock tire and wheel, the front tire shoulder and fender easily interfere with each other that tire shoulder should be inset and the tire size should not be bigger than the stock size. For setting exactly, you might need to fold the edge of fender.
* For the tested vehicle height, the fog height does not meet the Japanese regulation. Depending on the height setting, you might need to take it off.
* 5. For changing the bump rubber to L=5.
* First, drive with dial-15 and if you want more smooth feeling, change it to dial-30. Or if you want faster damping force or thick damping feeling, please set to dial-0. We recommend dial-0 to 5 for circuit attack.
