Point

HIPERMAX R is born with the latest theory in addition to cultivated through the popular HIPERMAX IV SP. A thorough review of each component and the know-how cultivated through the HIPERMAX S were totally utilized, resulting in an amazing evolution.
The new kit is released by equipping the new parts in addition to the know-how cultivated by HKS. The ride quality has been changed from conventional dampers.
The ND Roadster model has bonded bracket bushings with the front and rear stabilizers. When the ride height is lowered from stock condition, the stabilizer constantly absorbs the bush reaction force, which prevents coilover from performing well.
Three settings of stabilizer were thoroughly tested at Fuji Speedway: adoption of the stock stabilizer with bonded bushings, adoption of stabilizer with detachable bushing, adoption without stabilizer.
The test vehicle is the "S Special Package" model, and a strut tower bar that is factory-installed on the "NR-A" model was also adopted for the test.
At Fuji Speedway, please make adjustments according to your preference from 5 notches back from the front and rear tightening side.
By installing front and rear retainers, the rate change is minimized while the spring is compressed and abrupt movement changes are suppressed.
Although it is the vehicle height at testing, there is a risk that the kit is interferenced with the inner fender depending on the tire size, model or suspension alignment.
