TRX4 Brass Portal Upgrade | Over 500% weight increase!!!

In this video I add some brass portal covers I got for my Traxxas TRX4 Sport rock crawler/trail truck. I know the brass upgrades have gotten crazy but I think this one will make a great difference in the performance of the truck and they did not break the bank! I cannot tell you how others fit and go together but the ones I got were awesome and went together perfectly. You will need a couple 3mm lock nuts to complete the upgrade but I am sure you will have a couple stashed away somewhere!
Percentage Increase=Final Value minus Starting Value then divide that total by the Starting Value then multiply by 100 to get percentage
29.6 for both stock plastic
203.4 for both brass replacement
587.162% increase!
