This part is truly amazing! As it says, the shaft i made out of titanium. titanium is extremely strong! Also the stock drivshafts that xmods come with are really heavy. This unnessasry rotational mass robs your motor of torque and top end. If you were the motor, what would you rather turn? A 5lb shaft or a 1lb shaft? The motor in your cars will pretty much act the same way. It will rotate faster, and easier! This will restore the torque and top end of your car! The cf driveshafts that i have found on other sites are ALITTLE lighter. And alot more expensive. This is a great buy! But dont take my word for it! try it for your self!
