Point
・We have developed MAX IV for comfortable in the town drive and have competitive drive at the track. However the main use should be street, not the racing. The smooth movement of the suspension provide comfortable ride. The Evo is a sporty car so we have set it to suit it. HKS has developed MAX IV from 0, so it has 1 kg up of front spring from MAX III and it has better roadholding and less under steer. MAX IV has awesome drive feeling and have better performance.
* Rear spring seat has 374mm shortest case and length at 31mm thread position for avoid interference.
* If rear tire interfere with fender when bumping, please extend the case length and use bump touch. But if it extends too long, it will be uncomfortable by bump. So please make it a relevant length.
