I see you have you adjusted the coilovers. If you've hardened them up all round you may find the car very difficult to keep straight. Potentially if your front settings are soft and the rear hard you'll oversteer like a bitch too. Are you sure the adjustment on the coilovers is working on all four?

Secondly do you have adjustable ARBs. If you've tightened them up (maybe the alignment place?) you may find the rear end extremely skittish.

Third, tyres. Maxxis?? I've not seen any performance tyre from that manufacturer that has been rated particularly? What model as it were?

Trouble is you've changed quite a lot at once, so need to work through them all!
