As alot of people know the R33 has a very annoying axle tramp off the line.I dont know if this has been covered before but how can i get rid of it?

Im getting a set of pineapples for the rear but surely this alone wont stop it.

Now this is close to my heart.I have asked this question a few times myself.I installed pinapples and this reduced it somewhat but was still almost the same.Replaced the springs and shocks with kings springs and much improved shocks but only a little better again.Still,a worth while improvement.Replaced the wheels with light weight ones and you guessed it,only a slight improvement.After spending what was now a few thousand dollars I was stopping the rear end from trying to rip itself out of the bushes so then replaced the bushes with whiteline ones and this was yet another step in the right direction.

So I went to some people in the hot rodding scene and found that they had great success with urathane diff mounting.This means the subframe as well.You see a solid diff is difficult to control due to it`s weight but an IRS has far more mounting points,each one of which has the potential to move under accelleration causing the tyres to bite then skip repeat,repeat etc. etc......My next step is to replace the subframe bushes with urathane and the diff mounts as well.I have a strong feeling this will eliminate axle tramp all together.I know CUBES did this so would be interested to hear if it affected his 32.HEY CUBES,you reading this?

Thanks Gary atleast now i know what to tackle.Looks like ill be buying alot of urathane lol

Sydney kid, One day u have to come help me fix my axle tramp. Ive been trying for years to get rid of it to no avail. Been to suspension shops, tried different tyres, installed pineapples, and was about to change shocks and springs.

It just never wants to go away

I replaced my subframe bushes and found axle tramp has reduced greatly and torque steer feeling through second gear has completely dissapeared; on the dyno the whole sub frame was moving around a hell of a lot.

Most of the time it doesn't axle tramp but when it does its now a light little thud not like the old BANG BANG BANG your going to break an axle bang. :S

The subframe bushes Improved axle tramp 10 fold. I am still on stock shocks and springs as almost everything aftermarket is lowered which I don't want. Minimum legal height here in SA is 360mm mine sits ~365mm with stock bits.

I'm considering a set of teins as they have the screw type heigh adjustment that can be adjusted to stock/legal height.

What about the traction rods? I had a look at mine and they do feel a 'tad' loose, possibly the bush is stuffed which causes tramp. Reading up on them 'apparently' traction rods in good nick prevent tramp?

Nisskid,

A mate of mine runs the bilsteins and they are still too low. Unfortunately he has recently been defected because it was too low. From memory the front was too low 10mm and rear 5mm.

If you look and ask everyone who's been defected and what for its almost always.. 1. too low 2. tint 3. too loud

I've almost been done for tint so I removed it on the spot. Height, even though it looks stock a tape measure was put to it.

Its simply not worth the hassle.

Are yours on the highest setting? Are you able to measure the front and rear heights?

rear sits on just 340, the fronts sit about 350, that is the reccomended setting but not the highest, i beleive there are 2-3 grooves above this one which are a bit under 10mm apart. i have the extra grooves but most are for lowering it further, if i put mine on the highest setting i reckon it would sit a bit above standard height which is with lowered springs. id talk to SK about it but pretty sure the bilsteins with extra grooves would be more than enough to keep standard height.

Where the rear end of the car, on a launch will basically "bounce" and is then hard to get the power down and at the drags, will ruin your pass basically!

Is the bilstein setup that SydneyKid sells good/stiff enough to prevent this?

Do good grippy tires help prevent it too?

To be honest - I myself havent had much axel tramp issues in this car. My old VT LS1 commodore had major issues - was a biatch to drive :laugh:

Since I've had the syd kid group buy springs/shocks in my car Ive only done one night at WSID drags and had a little bit, but I think that was due to my "hard launch" (1 launch out of 5) - done a few motokharna's where you need to get a good launch for a good time - no a/t at all

Tyres - I guess? but Im not 100% sure - I used semis for the first time last weekend at DECA for a motokharna and had no issues

So in my case - 98% of the time - I havent had it!

    • I did end up getting it sorted, as GTSBoy said, there was a corroded connection and wire that needed to be replaced. I ended up taking out the light assembly, giving everything a good clean and re-soldered the old joints, and it came out good.
    • Wow, thanks for your help guys 🙏. I really appreciate it. Thanks @Rezz, if i fail finding any new or used, full or partial set of original Stage carpets i will come back to you for sure 😉 Explenation is right there, i just missed it 🤦‍♂️. Thanks for pointing out. @soviet_merlin in the meantime, I received a reply from nengun, and i quote: "Thanks for your message and interest in Nengun. KG4900 is for the full set of floor mats, while KG4911 is only the Driver's Floor Mat. FR, RH means Front Right Hand Side. All the Full Set options are now discontinued. However, the Driver's Floor Mat options are still available according to the latest information available to us. We do not know what the differences would be, but if you only want the one mat, we can certainly see what we can find out for you". Interesting. It seems they still have some "new old stock" that Duncan mentioned 🤔. I wonder if they can provide any photos......And i also just realized that amayama have G4900 sets. I'm tempted too. 
    • Any update on this one? did you manage to get it fixed?    i'm having the same issue with my r34 and i believe its to do with the smart entry (keyless) control module but cant be sure without forking out to get a replacement  
    • So this being my first contribution to the SAU forums, I'd like to present and show how I had to solve probably one of the most annoying fixes on any car I've owned: replacing a speedometer (or "speedo") sensor on my newly acquired Series 1 Stagea 260RS Autech Version. I'm simply documenting how I went about to fix this issue, and as I understand it is relatively rare to happen to this generation of cars, it is a gigantic PITA so I hope this helps serve as reference to anyone else who may encounter this issue. NOTE: Although I say this is meant for the 260RS, because the gearbox/drivetrain is shared with the R33 GTR with the 5-speed manual, the application should be exactly the same. Background So after driving my new-to-me Stagea for about 1500km, one night while driving home the speedometer and odometer suddenly stopped working. No clunking noise, no indication something was broken, the speedometer would just stop reading anything and the odometer stopped going up. This is a huge worry for me, because my car is relatively low mileage (only 45k km when purchased) so although I plan to own the car for a long time, a mismatched odometer reading would be hugely detrimental to resale should the day come to sell the car. Thankfully this only occurred a mile or two from home so it wasn't extremely significant. Also, the OCD part of me would be extremely irked if the numbers that showed on my dash doesn't match the actual ageing of the car. Diagnosing I had been in communication with the well renown GTR shop in the USA, U.P.garage up near University Point in Washington state. After some back and forth they said it could be one of two things: 1) The speedometer sensor that goes into the transfer case is broken 2) The actual cluster has a component that went kaput. They said this is common in older Nissan gauge clusters and that would indicate a rebuild is necessary. As I tried to figure out if it was problem #1, I resolved problem #2 by sending my cluster over to Relentless Motorsports in Dallas, TX, whom is local to me and does cluster and ECU rebuilds. He is a one man operation who meticulously replaces every chip, resistor, capacitor, and electronic component on the PCB's on a wide variety of classic and modern cars. His specialty is Lexus and Toyota, but he came highly recommended by Erik of U.P.garage since he does the rebuilds for them on GTR clusters.  For those that don't know, on R32 and R33 GTR gearboxes, the speedometer sensor is mounted in the transfer case and is purely an analog mini "generator" (opposite of an alternator essentially). Based on the speed the sensor spins it generates an AC sine wave voltage up to 5V, and sends that via two wires up to the cluster which then interprets it via the speedometer dial. The signal does NOT go to the ECU first, the wiring goes to the cluster first then the ECU after (or so I'm told).  Problems/Roadblocks I first removed the part from the car on the underside of the transfer case (drain your transfer case fluid/ATF first, guess who found out that the hard way?), and noted the transfer case fluid was EXTREMELY black, most likely never changed on my car. When attempting to turn the gears it felt extremely gritty, as if something was binding the shaft from rotating properly. I got absolutely no voltage reading out of the sensor no matter how fast I turned the shaft. After having to reflow the solder on my AFM sensors based on another SAU guide here, I attempted to disassemble the silicone seal on the back of the sensor to see what happened inside the sensor; turns out, it basically disintegrated itself. Wonderful. Not only had the electrical components destroyed themselves, the magnetic portion on what I thought was on the shaft also chipped and was broken. Solution So solution: find a spare part right? Wrong. Nissan has long discontinued the proper sensor part number 32702-21U19, and it is no longer obtainable either through Nissan NSA or Nissan Japan. I was SOL without proper speed or mileage readings unless I figured out a way to replace this sensor. After tons of Googling and searching on SAU, I found that there IS however a sensor that looks almost exactly like the R33/260RS one: a sensor meant for the R33/R34 GTT and GTS-T with the 5 speed manual. The part number was 25010-21U00, and the body, plug, and shaft all looked exactly the same. The gear was different at the end, but knowing the sensor's gear is held on with a circlip, I figured I could just order the part and swap the gears. Cue me ordering a new part from JustJap down in Kirrawee, NSW, then waiting almost 3 weeks for shipping and customs clearing. The part finally arrives and what did I find? The freaking shaft lengths don't match. $&%* I discussed with Erik how to proceed, and figuring that I basically destroyed the sensor trying to get the shaft out of the damaged sensor from my car. we deemed it too dangerous to try and attempt to swap shafts to the correct length. I had to find a local CNC machinist to help me cut and notch down the shaft. After tons of frantic calling on a Friday afternoon, I managed to get hold of someone and he said he'd be able to do it over half a week. I sent him photos and had him take measurements to match not only the correct length and notch fitment, but also a groove to machine out to hold the retentive circlip. And the end result? *chef's kiss* Perfect. Since I didn't have pliers with me when I picked up the items, I tested the old gear and circlip on. Perfect fit. After that it was simply swapping out the plug bracket to the new sensor, mount it on the transfer case, refill with ATF/Nissan Matic Fluid D, then test out function. Thankfully with the rebuilt cluster and the new sensor, both the speedometer and odometer and now working properly!   And there you have it. About 5-6 weeks of headaches wrapped up in a 15 minute photo essay. As I was told it is rare for sensors of this generation to die so dramatically, but you never know what could go wrong with a 25+ year old car. I HOPE that no one else has to go through this problem like I did, so with my take on a solution I hope it helps others who may encounter this issue in the future. For the TL;DR: 1) Sensor breaks. 2) Find a replacement GTT/GTS-T sensor. 3) Find a CNC machinist to have you cut it down to proper specs. 4) Reinstall then pray to the JDM gods.   Hope this guide/story helps anyone else encountering this problem!
