S2000 Special parts that can be changed to the ideal geometry by modifying the roll center are now available.
The lower arm angle of the S2000, which has been lowered, has an inverted C shape, and the roll center point is too low.
When the center of gravity of the vehicle and the roll center are separated, the amount of roll increases and the cornering force is sacrificed.
Suspension stroke is also reduced to lower the limit.
By installing the J'S RACING roll center adjuster, the lowered roll center can be corrected to the ideal position (the distance between the center of gravity of the vehicle and the roll center is corrected to a short position), and the ideal suspension geometry is realized.
[Installation effect]
★ Reduced roll amount
★ Improved tire contact feeling
★ Improved steering responsiveness
★ Increased cornering force
Super durability, special parts born from time attack participation know-how Can
be used regardless of stage from street to circuit I will.
J'S RACING repeats TEST many times and has a lineup of 12mm, 20mm, and 30mm, which are optimal for correcting the roll center of S2000, according to the set vehicle height.
Please install after confirming the usage environment.
(Usage example 1) * 10mm to 20mm vehicle height down vehicle
rear roll center adjuster → 12mm recommended
(Usage example 2) * 20mm to 50mm vehicle height down vehicle
rear roll center adjuster → 20mm recommended
(Usage example 3) * Vehicle height down of 40 mm or more
Rear roll center adjuster → 30 mm recommended
* The above figures are for reference only. Select the appropriate height depending on the circuit and suspension.
* It is not recommended to install it on vehicles with normal height.
The tilt angle of the roll axis (the line connecting the front and rear roll centers) is also a very important point when setting the S2000.
When installing the rear roll center adjuster, be sure to install the front camber joints S1 and S2 and the roll center adjuster plate before setting the geometry.
* Cannot be installed on 16-inch vehicles.
* 18 inch or larger wheels are recommended.
17-inch wheels can interfere with the shape.
Press work is required for mounting.
* After mounting, check the tightening of bolts and nuts on a regular basis.
Especially before driving on the circuit, please do it every time.
