    Lighter DS is great but significantly lower throttle response gains than lighter wheels and rotors... rotational inertia/angular momentum etc.

    Rotor gains... StopTech front 2 piece S550 vs std nearly 8#/corner, Racing Brake rear 2 piece nearly 6 #/corner... total is nearly 30# (unsprung, rotating)...

    Yes for sure... this is all motherhood stuff... but it should be considered (immediately after lighter wheels) if handling and throttle response gains related to weight loss is a goal.

    SO, how about some new write ups on the CF drive shaft experience after extended use?

    I'm sure the CF driveshaft is an improvement over the stock two piece, but I wonder how it compares to an aluminum driveshaft?

    Will it fit? Which transmission is in the FP350S?

    I love my QA1. Other than having the first two damaged in shipping, it’s been solid.

    No clocking, no adjustments, no vibrations. I’ve gotten it up to 160 at the track and there isn’t a hint of issues.

    Far better quality than my DSS one I had.

    I have had issues with two DSS CFs. Both failures likely due to excessive heat given how very close the DS is to my 2 exhaust pipes. The heat breaks down the glue joint between the CF and rear diff coupler, thus the DS breaks free and is spinning on the coupler. DSS has been fantastic in helping resolve the problem and given my second failure I have changed to a DSS aluminum.

    I've had my QA-1 CF shaft in the GT350 since January. After two Optima Ultimate competitions which include very hard track days, autocrosses and "speed stop challenges" which are basically drag races, I can say that it works great. Max speed for me is 148 (by GPS) at VIR. I'm just disappointed that no one can see it as it is a nice looking piece.

    Did you install your Carbon Fiber driveshaft from the The Driveshaft Shop? If so any issues?

    Hey there all ! Sorry for the lack of input on this subject ! I had the best intentions of doing so but then my wife and I had twin girls :eek::D! To say my hands are full is an understatement !:D:D:D

    Yes I did indeed install the driveshaft (about 1.5 hours) and did a full season (6 events) with NASA Rocky mountain in HPDE 3 and had no issues at all ! Great investment. ! No Vibrations no wobbles, noises etc. !

    The worst part was rounding off one of the Ford OEM fasteners from the driveshaft to the rear diff trying to remove the OEM driveshaft ! Had to cut it off ! Other than that all smooth sailing !

    In the next week I'll be switching over from DSS Alum to DSS CF and hope to feel the diffrence on my 12' Boss.

    @cghawk, you running with NASA at Pueblo, PPIR or HPR this year. If so, stop by and say hello. I'll miss the July one at HPR but should be there in October.
