R32 GTR driveline shudder when taking off in 1st

hey guys,

have an issue with my 32 GTR

car was parked up in december to do a single turbo conversion,

did not touch the driveline or rear end and the car drove with no issues.

finished it up in april and started getting massive shudder/ tramp in 1st gear

its a nismo coppermix twin plate so should drive like stock, found the only way to avoid it is to drive it like a button clutch.

goes through all the other gears fine, is only on take off.

have since replaced diff fluids with the nissan recommended stuff, only thing i can think of is the suspension being compressed for a while on one side while i had the front passenger side jacked up; mightve seized something?
 

thanks

Sorry should have been clearer,

yeah it’s axle tramp, brutal axle tramp too. Entire car feels like it’s shaking apart.

 

Prop shaft for the awd was out too so it’s definitely coming from the back

Could be suspension....but I wouldn't put money on it.

Likely to be tyres, from sitting still for months. Flat spot, gone hard, whatever.

I am usually tempted to just blame the stupid R32 anti-squat geometry. I've never been able to stop my shitbox from axle tramping like a flea-bitten dog on meth.

I managed to get my sedan to stop with a proper alignment.

I’ll rotate tyres and see if anything changes, it’s so weird. Only does it when taking off normally, if I drive it like a button clutch, no issues 

nothing between the gears either, it’s like butter

I’ve checked everything, going to dive under the thing tomorrow and double check in case I missed something.

if the box has to come out again, someone kick the stands lol

Alright checked the tail shaft and gearbox mounts with a pry bar, seems to be all good.

starting to think it’s clutch related..

has anyone had a Nismo dual mass flywheel failure?

Yep, standard front and rear diff

again the car drove fine in December, all I’ve done was pull off the twins and fit up a single turbo set up. 
encountered the vibration when I pulled the car out and turned it around for the tow truck before we went to the fabricators.

assumed it’s just one of the massive boost leaks pre plumbing but here we are. 
still shaking it’s tits off

alright fellas,
clutch is no good, no idea why, how or what but im just going to slap a new clutch into the dog and call it a day.
local r32 guy has the exact same issue, seems to be one of the plates fusing to the pressure plate or some shit.

ill post pics when i get the thing out xoxo

      R32 update from 1990's spec.

      New CAS just turned up from NZ Wiring. Looks like a nice bit of gear.  So, yeah. Triggered, bro. Realised I may as well do the cam belt while mucking about with it so will order one of them.

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.
