See: 175RC

175RC have introduced 8 new types of shorty LiPo weights for 2WD and 4WD buggies. Four types are available: A (18g and 36g), B (12g and 23g), C (12g and 23g) and D (12g and 23g) which all have unique characteristics to allow you to tune and move weight around while keeping it as low as possible. Type B can be flipped front to back in order to move the weight forward or backward  or inside/outside (4wd)   These are a great tuning option for any vehicle running a shorty battery pack whether it be mounted sideways or inline.
