Gravity RC introduce an outer hinge pin set for the Xray T4 line of cars. They are designed to reduce the unsprung weight of the suspension at its greatest point of instance and not only fit the T4 but also the T3 and T2. The total weight of all four pins is 2.5g and this makes for an unsprung weight saving of over 2 grams in total.
