I have a sypdershaft 1pc DS on my 2008 GT
My mods are:
4.30 Gears
Steeda Tri-ax
Corsa Extreme Exhaust
SLP LongTubes
SLP Catted X
Steed U/D Pulleys
Steeda Charge Motion Plates
Steeda CAI w/90mm MAF
NX Plate kit w/ 125 shot
Spydershaft 1pc Driveshaft
Steeda Sport Springs
Steed Adj Upper Control Arm
Front Tower Strut Bar
My car vibrates like crazy after 75mph and feels like the car is going to fall apart over 100mph. The noise and ride quality are absolute garbage after 75mph.
I have tried different pinion angles according to what Steeda suggests as well as Leonard racing suggests to no avail.
This weekend I am going to try and put the stock DS back in to see if it goes away or if it is related to the gears.
From what I have read on other forums, an LSD would take care of the problem because apparently Ford's design is the main issue. Yet, others have no issues. The car the DS came off of had no issues with vibrations and had a set of 4.10's on the car.
Has anyone else experienced anything similar? I'd hate to think I am alone on this one. I would much rather remove the driveshaft and sell it to someone with 3.73's or 4.10's than purchase an LSD for .21 of a second on the 1/4.
