I was wondering if I make all kinds of performance and suspension modifications...Would this be beneficial to an regular everyday driver? If so how???

 

it's all in what you want to get out of your maxima..

some mods are for low end - CAI
some mods are for high end - Catback
some mods are for looks - Aero Kit
some mods are for free - corner lights
some mods are just better for everything - y-pipe

 

Here in Chicago rush hour on xprswys can mean 75-80mph just to hold with traffic. Those extra HP help getting on and keeping up. I don't endorse everybody speeding but that's life. Guess the suspension & brakes help getting off the hwy?
