        day and night

        The difference between my old Driveshaft and this one is day and night. It feels like a brand new car. Absolutely worth the money. First gear use to not engage right away and would lag. Now it takes off like it should and gears shift slot smoother.

        Best Modification I've bought

        Yes it's expensive. If you think it's too expensive then you don't know what RandD costs are. That's the biggest gripe I hear about these driveshafts, and really, it's not that bad for what it is. Now, the good stuff. this is THE BEST modification I've made to my Mustang. There's no slop when shifting gears now, it feels like a bolt-action "action", no clunking when I down shift at speed into a corner, no vibrations at any speed, throttle is now CRISP and very smooth and instant, I mean instant. They didn't highlight how smooth it actually makes EVERYTHING. The biggest thing I noticed is how it just made everything better: positive/direct power delivery from engine to tire, throttle response, and body/drivetrain vibration reduction. And WOW, did it make it quicker, I noticed a difference as big as from stock tune to custom tune, yes, it actually made that big a diff. I noticed more of a performance gain from this, than just about everything else I've put on. I went from a mid 12 (12.854 seconds) to a low 12 (12.376 seconds), with just the carbon driveshaft being different from previous runs. I've dropped a consistent .5 (averaged) seconds in my E.T. This is my daily driver, and it made it more fun to drive, I think I might be getting better mpg too if I could just keep my foot out of the firewall. Buy it if you can afford it, buy the Aluminum one if you can, but get rid of that 2 piece, it's ruining the mustang, you won't believe how nice your ride drives with a single driveshaft. I would recommend this as the FIRST thing to replace on a Mustang. It'll change your life...seriously, it's my favorite mod. Thank you DSS and AmericanMuscle, you turned my Idaho-9 into a California-10.

        Great product

        Install was a few hours work. Reduction in weight is unparalleled and noticed an immediate difference in overall acceleration. Plus the awkward noises from two piece driveshaft are a distant memory
