Although personally I would not recomennd this (then again im not all that handy with a jack and spanners either).

Its far simpler to take it to your local suspension specialist, have him throw it up on the hoist and use a rattle gun.

*puts shovel to one side*

As a few recent threads are linking here, i thought i'd link

my piccies of when i installed mine..

Coz i'm that nice kinda guy.. :(

P:S Please stop to admire my leet photoshop 5killz on the arrows ...

i am very interested in these pinapples!! i got my hr31 gts pilarless and it axel tramps badly!!! the bush on the bak of my diff(i think its claed a bush thats what i was told) that is between the petrol tank and the diff, the rubebr bit is broken, and im getin that repaired and see if it stil does it after that if it does ill get these pinapples for sure!

Axel Tramp aka Wheel Hop also leads to broken rear ends, this is frame power being surged when the tire hits the ground and the gears being jarred. Also the U-Joints can suffer when the rear assembly moves out of align.

I'll motion that... i found out the hard way.

one night at the strip... Massive axle tramp... my rear end wasn't too good anyways, but that totally killed it.

Diff mount if snapped/damaged and the bush has just about given up the ghost

:uh-huh:

So me gonna be getting some on the R31 :(

I'm still curious as to what actually causes axle tramp tho... I mean my car is 100% in the dry on the street, i get slight axle tramp in the wet on the street but on the 1/4 i get major major axle tramp all with exactly the same setup.

Is it stiff suspension, soft suspension, faulty part, etc etc

Interesting that you set up the axle for drift?:(

If you guys are having traction issues, make sure you tilt the cradle back, not forward. Also, using hardmount (alloy) spacers and cutting back the stock bushes will rigidly secure the cradle to the body, and goes yet another step forward in assisting traction and reducing axle tramp.

Hey benm wot mods have you done to achieve 192kW @ 12 pounds? I have the same car as you and was wondering what was a good mod for the money, after reading this pineapples review i will certainly get some in the near future. But any other ideas, suggestions? Atm i'v got a 3.5 inch stainless cat back kakimoto exhaust and a apexi pod with a home made heat sheild which utilises the stocky snorkel. I will soon be getting 3 inch from turbo and a high flow cat after that wot would you suggest? I just want a pretty tuff streeter and wanna car that can drift a little better (coilovers so damn exp tho, ah well i can have a wish list).

Is everyone aware that there are three ways to install the "Pineapples",

1-Standard-rear subframe alignment normal

2-Drag-rear subframe declined to promote squat

3-Drift - rear subframe inclined to inhibit squat

Another thing to consider is the state of your stock subframe bushes which contain a fluid to minimise hash ride, noise and vibrations.

In my case two of the four had busted and there was severe movement in the rear end, also very noisy over bad roads and severe wheel hopping when launching hard.

Pinapples only work when installed with the original fluid bushes.

You cannot purchase these bushes from anywhere. You can only buy a subframe from a wrecked car and swap the whole thing over- big job!

Instead i had solid aluminium bushes installed that completely lock the subframe rigid to the chassis.

Very responsive steering and rear end control but extreme harshness thru suspension and vibrations from the driveline at 40-45KPH

Computalign in Nunawading jsut installed mine yesterday.

How much vibration did everyone get?

I get an audible vibration when accelerating hard.

Back end shudders and I don't really like it all that much.

Vibraton is the enemy of everything.

    • 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. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
