R33 GTR Front shaft Hub Spacers

[The Mafia]

Hi Everyone. 

I have a few questions about front  drive shafts. Has anyone ever used spacers or required and obtained some slightly longer drive shafts?

I want to increase my front camber by pushing the bottom of the wheel outwards about 10mm but when we did that it extended / stretched the driveshaft too much and a blew a driver side shaft taking a left corner at high load on a hill climb. Seems that it pulled the CV apart / out because it was stretched too far. Some have asked me if my mounts are okay - well they are brand new (Everything is new)

The car is a R33 GTR that has been fully built for circuit. I'm pretty sure that R32 / R33 and R34 GTRs all use the same front driveshafts.

I cannot pull the top in anymore unfortunately. Plus filling the guards outwards would be nice and give me more track.

I'm not really a suspension guy. Engine / Tuning is my area so go easy on me if I have said anything stupid.

The main bits underneath are Ikeya Formula so I have a lot of adjustment.

Also Running a quaife front diff and Full Race AWD controller so the AWD definitely gets a hammering.

I have spoken to GKTech and he said they make these for the rear, but I would like to know if they fit the front too. Has anyone ever done this before?

well, I'll start by saying my experience is 32 not 33 gtr.

I have the hub moved a fair way out by spacing out the lower control arm mounting. I don't have the exact measurement handy and don't want to guess.

But the point is, both the bottom of the wheel (and the hub) are a fair way wider than standard, and no I've never had a problem with driveshaft length

Is the piece GKTech making just the black part in the picture or the whole bearing/stub axle part? I could measure up driveshaft diameter front vs rear to confirm diameter fits, and you should check you have sufficient thread on the head of the driveshaft to get the nut on properly if diameter is the same.

I think you'd also have to confirm the ABS sensor still runs across the teeth OK. 

Overall....seems like a lot of work to deal with something that may not be an issue. If it was I'd go custom driveshaft with a longer centre shaft rather than all this stuffing around at the hub

Hi Duncan

Thanks for the reply. 

The only piece that GKtech make is the black spacer:

 

 

I was just thinking that f the ABS teeth are mounted on the shaft then there will be an issue with the spacers installed. I use the passenger side ABS sensors too as my second wheel speed input. 

This is going to be interesting. I might need to get custom shafts made up. Do you have somewhere you have them made? Or do you just use the drive shaft shop?

I would suggest the Driveshaft shop. (the guys in NC, USA, that is). Expensive, but you will likely get exactly what is needed, with no compromises.
