Buying 380 Mods

[Shadow565]

Looking for the Whos, Wheres and $$$s of 380 Mods.

Apart from the Typical Exhaust Mods and no Turbo/SuperCharger

1. Piggyback ECU?(Cars going to be a long laster hopefully, so this will see its worth)
2. Galant Intake?(Everyone mentions these, is it because the 380s have a tiny intake?)
3. Coilovers(Not sure about these as the GTs Suspension is very nice, but i'd like a adjustable ride height)
4. HIDs(My friend brought from a Aussie eBay Reseller of Chinese ones but his have had a few issues, anyone have a reccomended brand/seller?)
5. AUX/Bluetooth Audio(Anyone have anything on this?, i'd prefer to keep it a stock headunit but having neither of these options kinda annoys a young person like me)
6. Forged Pistons(A Biggy but some info on them would be awesome)
7. VRX/TMR Front Lower Grill & Rear Matching Panel

I'm presuming i've forgotten something or don't know about others, feel free to inform the newbie

EDIT:
8. Shift Kit?(On a Manual these are more common but is there anything for an auto?)
9. Brake Upgrade, A Rather obvious one, anything in particular with the 380s brake setup outside of the norm?
EDIT2:
10. AntiSway, Is there a better option then the factory AntiSway?, or just rig up my own?
