I'm a full noob with these trucks (calling them trucks is an upgrade, isn't it?) but here are my top 3 to date
1. f/r suspension lift and level using OME blocks, shocks and springs
2. head unit swap (need to add sound deadening)
3. black out package (in progress) debadge, paint rims, projector headlamps
4. TLC hood strut upgrade per [MENTION=114619]cbr900boy[/MENTION] (just ordered struts)
Future upgrades still in research stage
a. 4x4 conversion
b. supercharger
c. LC suspension
d. functional hood scoop
