E2428a	Rear Wing Stay (+15)

E2428 is 15mm higher than E2422 and can be equipped a rear wing to 6mm forward.

In general, the more you higher the rear wing, the rear grip of the car will be higher,

but at the same time the roll in the rear also increase, so stability may be impaired.

Using E2428 makes it possible to suppress the roll in the rear and the rear grip feeling

is the same by lowering the mounting position to the rear damper stay even the rear

wing is the same height.
