I have a 1999 Infiniti I30 Limited and looking to change my almost all worn brake pads and lower my car. I am doing the work with a friend who is very knowledgeable about cars and does 90% of his work on is 94 supra. I looking to either go all out or go a lot cheaper.

1st option(all out)get the Brembo Brake Sport Disc kit for $500, get a Stillen sway bar for $250, and also get Eibach springs(pro-kit) for $200. Total $950 around

2nd option(cheaper)get calipor paint and paint them $20, Buy stock pads for like $100 tops, and $200 for springs, and $200 for sway bars

I need to know where can i get the repair manual for my car besides the dealer so i can save money. And does anyone know if i need shocks also. Also does anyone know where i can get good after market parts????
