I know this is another wheels and brakes questions but i see many different comments on these subjects i want to know which is better for me to go with for wheels 17s,18s or 20s cause they tell me with 17 or 18s i need to do more mods then with 20s and i will be lowering the car 3" in the front 2" in the rear and rolling the fenders but if i was to go with the 18s and i put 18x9.5 in the rear with 4.5 to 5"BS what wheel adapter will i get to fit this size tire on my Monte.Next question they said i can use 98 to 03 2wd blazer rotors and caliper and spindles as an upgrade but other people say it worthless cause the rotor is .5" bigger then the Montes so what upgrade should i use and i dont have alot of money so any places that you know where i can get brakes and suspension upgrades that i can buy at a good price would be great.
