"PINEAPPLES" - Before/After Review

[dan_the_man]

where is a good place to get these done in perth?

[rev210]

in your driveway is a good place to fit the pineapples, its cheap too!

[benm]

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.

[Steve]

Dan, I had mine fitted by C-Red in perth ALOT cheaper than $200.

[T0nyGTSt]

Well the Whiteline apples are like $110 and I didn't even look around...

Installation should be cheap esp. if they have a hoist. $50 is more than enough...

*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!

[Kutter]

would these help regardless even if you have aftermarket coilovers?

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

[benm]

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

[Steve]

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.

Thats what I thought....

[pinoi_boi_r33]

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).

[drifto]

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

[riggaP]

drifto,

when you say noisy do you mean loud 'clicking' that sounds like someone tapping the diff with a hammer??

[Bass Junky]

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.

[Robo's]

Wouldnt the vibration be caused thru the re-enlignment of the sub frame in the rear. You've altered the geometry of the rear therefore would have a nasty consequence being vibration.

Hmmm, i'm having second thoughts now.

[strutto]

No vibration whatsoever from when I fitted mine... If anything the rear of the car feels a heap better...

[GTR-Ben]

Every car I have fitted them to had no problems..

I usually fit solid poly bushes to my cars if I can also.

[riggaP]

Pineapples are not for comfort. The traction gains ceratinly out weigh the minor loss of comfort.
