Pineapples by themself squashing the stock bushes are rubbish. I chop the tops off all the stock bushes, leaving about 3mm of rubber on the back 2 to avoid metal-on-metal contact and leave about 8mm on the front 2 to angle it towards squat a little, put the subframe back in place, THEN put the pineapples underneath. This makes a heap of difference and is still quieter than solid alloy bushes.
Also there is a huge amount of movement and bounciness in the rear lower control arm bushes. U can see marks on the metal where the bush has touched but the bush is about 5mm away when still! Grab some delrin rear LCA bushes from cazmanindustries.com and that'll stop a lot of tramping imo.
Unfortunately, the whole driveline is supported by rubber bushes so if u want it the best that it can be, u'd be going with nismo engine, gearbox and diff mounts too. It all helps.
