Available all over the place in kits, but I discovered Fulcrum sell them separately so went out and grabbed some.
Large ones (80mm OD) for $17.56ea
Small ones (69.5mm OD) for $14.10ea
I just got the 4, but I suppose if I ever wanted to change the setup i could just go back and get another 2 small ones.
Their small ones don't come with a cut in them, so you may need to cut them if you want easier fitment for either a drift or drag setup.
Depending on how you want to set the rear cradle you only need to buy 4 pineapples. I have set mine in the standard position and only required 2 large and 2 small pineapples. If you want either a drift or drag setup you would need 4 small pineapples.
Total cost was under $65.
Fitting is simple and takes approx 45 - 60mins.
Tools required:
-17mm socket and breaker bar
-14mm socket
-trolley jack
-ramps make life easier
Photos below, as well as a link to the whiteline fitting instructions. They are pretty self explanatory, so once you have a read, look at the photos, and then have a look under your car it should be obvious what needs to go where etc.
I just backed my car up onto some car ramps (remembering to chock the front wheels), then did one side at a time, while supporting the subframe with a trolley jack (it didn't really seem to need supporting but that is what is stated in the instructions).
The Whiteline instructions only mention removing 2 nuts either side (one at the front and one at the back), but I removed an additional 2 at the front from the subframe mounting bracket (marked in the photos) to make getting the front pineapples on easier.
On the front I had to use the jack once I had fitted the pineapple to compress the subframe up enough to get the nut back on with a decent amount of thread, but once it was on it tightens easily.
The rear nuts are a bit hard to get at with a socket/ratchet due to the HICAS tie-rods sitting directly under the nut, so depending on the length/chunkiness of the socket and ratchet/breaker bar you are using, you may need a 17mm spanner as well.
Torque wise, I just tightened everything until I couldn't tighten it anymore (within reason). The nuts were pretty hard to break at first when removing them so I'd say you are pretty right to tighten like a bastard.
If anyone can see anything I have done wrong or would care to elaborate on anything, feel free
