The Exotek EB410 Rear Brass Weight Set was specially designed for the EB410. Made of brass and black coated to reduce corrosion, this weight set is designed to easily bolt on to the rear of the EB410 with an extra low profile. The main weight is 40 grams and includes two additional 8 gram weights (16g total add on plus the 40gr main weight) so that you can tune the rear weight of your buggy to suit different track conditions. The weight set is also slightly angled off of the chassis to help maintain chassis flex.
