You will like an LSD ;) My GT has some crappy 175 profile tyres on atm but it pulls and pulls around corners, only other handling mod I have are lowering springs!
I did mine satin black, just made sure the sanding was done properly, 2 coats primer, 2 coats colour all done! Hasn't cracked and it's been on for months and months
Win on those seats! Hoard of parts eh, loving it haha! Quick question on TD04, do you need new oil feed, return and water lines? And can you still use HKS actuator? Really wanna get me one of those mani kits!
