Adjustable aluminum rear suspension arm Type-3 has a 4-piece structure, allowing for a wide range of settings for arm length, trailing angle, shock mounting position, and wheelbase. The arm length can be adjusted in 1mm increments from 53mm to 42mm. Select from trailing angles of 0 degrees, 3 degrees, and 6 degrees. The front and rear width of the suspension arm is 7mm narrower than the stock suspension arm, so the wheelbase can be adjusted more widely than before. Although it is multi-functional and highly rigid, it weighs only 2.8g more (compared to normal), making it extremely lightweight! It is possible to achieve the best performance without worrying about weight balance!
