R33 GTR Front shaft Hub Spacers

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?

      Yeah since those first 2 replies I actually went and put some 98 in it and tbf it's already doing much better than the 95 (which is weird and makes my inner tinfoil hat wearer think the 95 was a crap batch), getting 8ish around town. Again, wonder if it takes a while to stabilize if the fuel is changed a couple of times. I swear cars used to just either run "well" or "s**t* in my 20s, none of this fuel optimisation business haha

      R33 headlight relay conversion?

      By GTSBoy · Posted

      Any number of different ways. Have the coils draw sufficient current to provide contact wetting. Use different contacts in the switch, either by material or design, better suited to the low current drawn by a relay coil. Etc.

      Hmm, how does the R34 manage to have headlight relays then without getting excessive carbon buildup on the headlight switch contacts?

      Not R7R. Meant to type R&R, obviously enough.

      R33 headlight relay conversion?

      By GTSBoy · Posted

      Bugger "making it look stock". I put one conventional internally fused Hella relay behind each globe. I just pulled the plugs off the back of the globes and built new loom segments with male and female plug parts to match up to the original loom and the globe, and used the original power wires to each globe coming from the switch through the original loom plug to trigger the relays. Ran a big fat (also separately fused) power wire across the front of the car to feed all the relays. It's as ugly as f**k, but it is wedged down between the headlight and battery on the RHS and the airbox and headlight on the LHS, and no-one ever looks in my engine bay, and on the odd occasion that they do I simply give no f**ks for what they think. Fully reversible - not that you'd ever want to. For f**k's sake. It's a Skyline. They made million of the bloody things. We've been crashing them into roadside furniture for 30 years now. There is a negative side effect to putting relays on the headlights. The coil current is too little to properly clean the contacts in the switches and they get blacked up and you have to open them up every couple of years and clean them manually. I have 25 years of experience on this point.
