One Piece Tailshaft Gtr

[T04GTR]

just for referance.. the "nvh" is a result of either an unbalanced shaft or incorect driveline angle. with a one piece shaft the amout of angular diferance is around 2 degrees. (diff pinion/gearbox output shaft angle)

has to be a paralelagram.

the more pieces the shaft is the less acurate or critical the angle has to be to not induce vibrations over around 80kph.

so.. with a 2 piece shaft you can be 4 degree out. 4 degrees on a 1 piece shaft would blurr the rear view mirror over 60kph lol.

a one piece shaft is better. lighter and more direct. well suited to racing with dog engagement boxes etc etc.

since our cars dont have a live axel you can make the angle very close. (shimming the box up or down.)

So are you in favour of one piece in gtr's without dogboxes,just curious??Cheers Grey Pearl.

Jump in on the group buy!!

i need some more people!

but do your research, i've done shit all i just want one because the price is good and i am trying to get my car as light as possible..

and the effects of one piece shaft dont bother me as its probably never going to get road registered again. and i like noise.

I just got my 1 peice put in late last week and it feels great. It seems to be really smooth and responsive. I thought it would be more jerky because it had no play because it is one solid shaft but it is alot better than the shagged two peice. I haven't really noticed any harmonics either and I have done some highway driving.

Last weeks of the group buy now, so if you want one people get in now,

credit card payments will be accepted, and they are now down to $1400 for 2000hp shaft delivered AU $$ not US $$ anymore

end plug..........

Just picked up my new custom 2 piece tailshaft from hardy spicer. Wont be running it for a few days but if looks are anything to go by its a winner. massive unis, thicker wall tubing, heavier yolk. All brand spanking including centere bearing for around 1. kay. My mate has ben running this on his race only 33 for a year or so now and its been bomb proof to date.

Looking forward to it as I am over the vibrations in the car caused by non serviceable uni joints.
