Hi all,

Dont know if anyone else has experienced this but I get a pretty bad vibration off the line under full acceleration, does not go away when 2nd comes in. This does not happen all the time. I noticed it was workse when someone is sitting in the back. Does the Stagea had a rear LSD?

Next one. Sometime when turning the wheels with at a standstill or going forward very slowly whilst turning I get a vibration. Just wondering if these two problems are interlinked????

Thanks in advance.

Ken

Hi Ken, I get the vibration when reversing slowly at full lock. I have checked the CV's and they are good. I will be changing the radius rod bushes shortly for more caster. They appear to be a bit worn (soft) so they maybe the problem. I also get a bad (harsh) vibration at 160 kph, I will get the wheel balance checked, but it feels more tailshafty. I don't have any vibration in first or second. :rofl:

I get same vibration forward or reverse, but not at full lock, and not every time. I had a similar vibration (acceleration) on my gtr race car, it was a centre bearing drama. The tail shaft should not affect my turning vibration should it? I was thinking lsd clutch plate prob, maybe transfer prob - I really dont know. Out of ideas. Let me know how you go though.

Cheers,

Ken

I too have a slight vibration when turning slowly. But i thought it was normal as when I push the snow button I got the vibration still but a little worse so I thought it must be the ALTESSA system thinking that one wheel was turning faster, whcih it does when turning. I think it is normal, but I will stand corrected.

Cheers ICE

I was getting vibration coming out of my Cam gear cover for a few days, but then it went away. i was worried my belt was about to snap

I'm getting my timing belt replaced tomorrow anyways, so hopefully that will solve that mystery.

Vibration under hard (not very hard) braking, no real suprise there but, anything that small trying to stop 1800kg of wagon is going to wanna argue. Rear brake pads worn out in 12 months, so I've machined rotors, put a set of R31 rear pads in at a 3rd of the price for the genuine ones and seems to be gone for now.

Yeah i get that bad vibration under braking too. figure i'll upgrade the brakes to a decent set of brembo's in the near future.

I'm not sure if it's just the ABS stuffing up or that the stock brakes are just crap

I changed the front shocks on the weekend and I noticed, when I have one front wheel off the ground, I can't rotate it. It is pretty tight as I can undo the wheel nuts (tyre service 120 ft lbs to undo them). If I leave it for a while, a few hours, I can then turn it. I assume this is the ATTESSA residual hydraulic pressure, this happen in the GTR's. Since I have the Stagea in Park, the tranmission is locked so the one wheel can't rotate independantly.

Keeping this in mind, the vibration when reversing is an indicator that the Stagea may have some form of LSD in the front. Anyone seen that mentioned in the specs? :P

My understanding is that the front half of the tailshaft is the same, but the rear is longer:cheers:

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
