if your wanting a fast car, i would wait on a custom paint job, stereo ect. i would go all out ***** to the walls on the performance. I put a expensive stereo in my car and i regret it. Tv's are not going to be used much unless children are in your car alot. I wish i was running about 8psi with a srt s/c or rmm s/c Instead i have two speakers that will break my rear glass before long If your pimpin, the tv effect is excellent, but for speed...its all a no-no...unless you have 500hp but this is my opinion of course

 

if you are getting fi in dec, don't touch the rear end at all. after that then you decide if you wanna put on the trd lsd. install would be very expensive. you wanna keep the stock gear ratio

if you don't fi ever, put on the rmm lsd and gain the better gear ratio of the rmm unit
