meggala takes 1 second off his 1/4 mile time

[adam 32]

yeh im chasing a set of these too!

mack tell me when ur getting yours and ill put in an order

we might get a slight discount if buying 2

[meggala]

macka you and adam get to gether and we will work some thig out theycome with full fitting instructions.

cheers

Top stuff Meg's A full second is a huge improvement! Gotta love those A032R's

Hopefully my semi-comps will be on very soon too (before AIR Dec 7th street meet)

I've got the Whiteline KCA349 kit fitted too. The car will still wheelspin but it does regain grip quicker than it ever did before I fitted the kit.

Having stock shocks is a big help in the weight transfer dept'! With nil suspension mods I managed a 2.1 60'.

The KCA349 whiteline kit is only $114 (3 pairs of different pineapples and instructions). I doubt you are going to get any discount on the purchase of only 2. But hey I hope you do.

If you guys are interested I can do a group buy from my source and do them for $95 a set delivered to your door with a special "Doctor Drift" instruction sheet, or if your in melbourne come pick them up for $90, and maybe get me to fit them while I'm there.... Only need 5 sets to get discount... I've already got an order of 3 from elsewhere.....

Keep your eyes peeled I'll do another 'Pineapples Group Buy' shortly.....

im in... should get me into the 14s

Im in and put Adam32 down too please

You cant get into the 14s?

whats the stock quoted times for an R32 Gtst? I thought maybe 14.7 r so..

[adam 32]

15.0-15.1

hence my dazzling time with the T04 on 8psi

Cool... we've got enough!!!

I'm flying around the country for work for next two weeks, if you guys can wait for delivery to you on 15th December I can sort it by then EASY as..... If you want them sooner I can work it out....

E-Mail me.,..

Doc.

what would PINEAPPLES do for a auto? Seens that auto's dont have has much traction problems?

[macka]

DrDrift i heard this fruit helps axel tramp on take off, I dont have any axel tramp so would i still need them?

No they don't help 'axle tramp'. At least not unless you put them in the 'drift /wheelspin' config.

They help stop wheel spin and may actually induce a little 'axle tramp' / diff bounce /hop as a result of the back tyres grabbing.

Tramp is more a problem associated with leaf sprung rear cars. Like the old falcons/chargers. For that we used to fit tramp bars (usually nice chrome ones -- the old version of rice when fitted to a stock six cylinder).

You must have pineapples!

Sorry dude, but you are way off there.... The "axle tramp" in skylines is actually subframe vibrations.... These pineapples DO REDUCE "AXLE TRAMP" in skylines in either configuration, and they also reduce wheelspin in grip configuration... The other factor is that they modify the angle of the subframe, similar to adjusting the angle in a 4 link drag suspension setup.... A few degrees difference alters the suspension geometry such that you will get more traction if you choose the grip setup....

I either configuration subframe vibration is completely eliminated... If "axle tramp" is still evident it would be entirely due to faulty shock absorbers....

Macka,

As I've mentioned in a couple of posts, it reduces subframe movement "axle tramp", and also modifies the angle of the subframe and helps reduce wheelspin...

So I guess if you have no axle tramp, and no wheelspin, then you either don't need these, or need mor power??

Fair enough. I don't know if your experience is with stock shocks and standard spring rates when you suggest that there is no 'bouncing'. Sub frame doesn't vibrate btw, it contacts the bumpstops, I marked them to find out with white ink (liquid paper). I since removed the front section of the pineapples (I'd only just put them in - doh!) back to my half a setup until/if I get firmer setup for the rear.

There is less clearance to the bump stops when the car squats thanks to the geometry change. My shocks are in good servicable condition ,tho' stock, and it never 'bounced' before (exactly the same behaviour as axle tramp tho' technically not the same thing I guess). There are other stock suspension lines that have the same symptoms (none of them have faulty suspension).Rob77 for instance. The only 'fault' is not having a firmer suspension than stock. But, hey I know that, we used to put in extra leaf springs before resorting to tramp rods. If you take away the compliance in the stock cradle mounts then the energy's got to be absorbed/transfered somewhere else, poor old stock springs and shocks.

Interestingly I guessed that I might get 'axle tramp' before I had even put them in because every time I have started down the path to rear wheel traction in past cars this has been a good sign that you are on the right track.

[Dr_Drift]

I've actually installed these in quite a few cars from 180's to R32's and even an S15... And in all cases axle tramp was reduced or eliminated.... I don't think any of them had the stock shockies in them however... so that may be it??

You say you're using the whiteline kit correct? I heard these are a three piece set... Do you know the thickness of these three bushes so I can compare the to mine??

Perhaps you could also explain the different geometry setups whiteline suggest? maybe there's something there and we're not comparing apples to apples if ya know what I mean??

or pineapples to pineapples :bahaha:

I think we are talking the same language. The stiffer shocks/springs reduce compliance in their own way but as a result perhaps the energy resident in the subframe mounts without the kit cause excessive movement in the diff cradle. Adding the kit in any form reduces this compliance/movement and eliminates the 'bounce'. I guess like everything its a case of the weakest link in the chain.

I'm afraid mine wont be much good to measure after getting installed they are bound to have squished down a few mm or so.

You can get a pdf off the whiteline web page I think with the install and specs?

Ok im getting the drift hehe

I have about 300rwhp

I cant better a 2.5 60ft with the HkS suspension not giving at all, 18psi tyres just light up and i cant get a medium between Wheelspin launch and bogdown and 2nd gear likes to send me towards the other lane...

The other thing is can you hear them? Any noise or driveability problems? or dont you know any difference
