Ok I am 17 just starting to learn about skylines an all so sorry for any "nooby" questions.
I own a stock standard 1994 R33 Skyline Coupe GT and im looking to uprgrade my front brakes seeing they have no compression and are warped. (very f**ked to drive) I ordered new slotted rotors and pads (without calipers) for my car and when they arrived the rotors are an inch in diameter larger then the ones already on it, they sent us 5 stud pattern first which we had to return $120 freight later -__-. we now have 4 stud rotors that are still too big. their explanation was i had R31 braking system on my car. i rang BrakeMart, they suggested someone couldve changed the braking system, and that the braking system on my car isnt the right brakes that i need to upgrade the current system to a 4 piston caliper to be able to fit my 4 stud slotted rotars and pads. WTF??!! I just want my brakes repaired and able to stop me safely and this has just turned into a mass frustration.
so my question is, is there anyone that knows how i can fix this epic dilema so i can uprgade my braking system???
(front brakes only, not even attempting rear at this point)
everything on the internet are saying i should have, VeDi on my front and Di-S on my back, does anyone know what these are or mean??
