Point
・MAX IV GT for GS450h is set with F Sport. We tried to set it stylish low-down and still have the stock GS450 ride. GS450hF Sport has more comfortable ride and has less unstability with handling in a roll than the GS350F Sport. GS450hF Sport is more comfortable and has better drivability. And we kept these advantages. We made to have S mode drivability and N mode comfort at dial 20. We set them comfortable as stock and still has upgraded handling for best drivability by the adequate adjustment for the spring and damper force. We set the enough stoke for a comfortable ride for both driver and the passengers. We tested with electronic device to have a best stability by delaying the electronic interference.
 
* 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.
* Fog/winker height for factory setting: 253mm (all in the headlight), For Testing: 234mm (all in the headlight)
*5. For changing the bump rubber to L=5.
*6 To have more height, please change it to L=250 (Approximate adjustable length: 0 to 49mm).
