Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
honestly mate ur prolly better off savin ur money and buying an ss later on hey instead of doin those mods on a 6er....coz there power gain isnt goin to be great for the cash spent....yeh but thats just how im looking at it....the most modified im guna go i think is extractors but yeh thats just me :thumbsup:
those mods ur prolly looking at at least $2500 and a kw gain of round 20-25kw i guess....but that money spent on an 8 ull prolly get 40-50kw gain :w00t:
