Yokomo B11-OP1A Option parts set 橫崛   [B11-OP1A]

A standard item for fine-tuning the drive system and suspension.
The front and rear aluminum drive cups are effective in significantly reducing the weight of the drive system compared to standard steel ones, and are extremely effective in improving throttle response.
The aluminum shock end ball is lightweight and allows the shock to move more smoothly, making it a particularly recommended combination for the stock category.
