First post ever. Have a few questions. Are performance parts for the coupes and sedans interchangeable? I have seen on a lot of sites that they offer parts for the coupe and not the sedan. Can I get parts for the coupe that will fit on the sedan? And if they are the same, why don't they just say for both? Also I am looking at doing some upgrades for my G sedan, I already have Stillen Gen 3, and Stillen exhaust. Not sure what else to get. I only want to spend about $2000. I was thinking HFC, Uprev tune, lightweight pulley, sway bars. Anything else or different? Headers? 4.08 gears w/ new LSD?

Recommendations would be great! Have at it.

 

Welcome. The simple answer is some parts are interchangeable between both and some aren't.

Of the mods you have listed, fir $2K I'd do the gear swap first, then sways, then HFC.
