I can't give a write up...but I can tell you something most people overlook. rims. 1lb. off of a rim would be like dropping 10lbs. from your car. so if you have 22.5lb. rims and you get the same size rims that weigh say...16lbs....that would be 6.5lbs. per rim for a total of 26lbs. it would equal out to you dropping 143lbs. from your car. no shit.
