If your looking for the absolute last bit of performance gain for your car AND expenses are not a CONCERN,then look at buying a carbon fibre matrix shaft or a little cheaper aluminum shaft. Epecaiily at that length The choice is yours I used the mopar drive shaft kit because I had two of them(free to me )and I was trying to build a fast street car with cost part of the decision making process. My new race car will have either a alunimun or chrome moly shaft, whichever is the best, strongest and lightest for that application with no price concerns, weight being the final decider
