Especially the blue coupe with the 3:46 gear. If anyone was going to have drive shaft issues, I would have thought it would be me or one of the V-8's. I do see more re-enforcement of the torgue over in the rear end, but that is a suspension problem not a drive shaft issue. If it proves to improve 60' times, I will be impressed. I have my doubt's though. 60' times is more of a hooking up issue. Right suspension right tires and tire pressure. We won't even talk surface prep. Good luck to you on your quest for faster times though. Nothing wrong with that.
I never like the idea of a center carrier bearing.
I spend alot of time out of state away from home, and getting rid of flex discs and center carrier bearing is less things that I would have to worry about.
From a non rebuildable steel driveshaft due to the u joint, with 2 rubber flex discs and a center carrier bearing to a fully rebuild able driveshaft with standard 1310 joints, and 1.8 lbs lighter, yes if I was going to overtake the project I wanted aluminum and not steel, a single piece steel would be heavier.
I have a N/A 6 speed so did not do for drag, but is I could find out how to strengthen the nsg370, I would and do a N/A 550 engine, I have been looking and asking for awhile, but no luck.
I have 162k miles on my silverfox and was getting ready to rebuild driveshaft anyway, and when I change or rebuild something I always look at improving it, not a person that thinks good enough.
It would cut 60'times for acouple reasons, but another thing you would have to think about also, with the ones that have modded 5.5 engines the rubber flex discs does give alittle shock absorbing for the hard launches, so it helps on the output torque rating on the transmission, but I use mine as a daily driver doing long drives and that does not a problem for me, and with the 3.2 it will not get to the torque rating.
I will definitely not have a problem with flex discs
