I bought a set of disc italia for for the rear of my Dodge ram diesel 3500. After I installed them I torqued the wheels down (145 lbs per manual) and noticed a large crack on both rotors running from the stud hole towards the back of the rotor. On Dodge its about 4 in from the rotor itself to the front with the stud holes. I called Disc Italia and they said it was due to over torque. I told him put the stock rotors on and torqued them down to 250 lbs with a 1/2 in air gun just to see what would happen. there were no problems, no cracks. Obviously the stock rotors are much stronger than the Disc Italia. I paid $315.00 a piece for the rotors. The best they would do was to sell me another set of rotors at their cost of $189.00.

I bought Disc Italia Drilled and Slotted rotors from Brakeworld to help with stopping power on my 2004 Chevy Avalanche especially when pulling my camper. Seven months after installing the rotors I found a crack in the driver side rotor when I had my wheel off to wash the rims. I tried to email them two times because I work from 7:00-6:00 and am unable to call during their customer service hours (9:00 to 5:00).
I called them today after no response from my email. I was told it was past the 90 day warranty and I could not return it for a new rotor. I have no idea when the crack occurred, it could have been before the 90 days.
I will never use them again because they don't stand behind their product. Having paid $239 for the front pair of rotors you would expect them to last longer than 7 months.
It is obvious that these rotors are inferior since they couldn't hold up under normal driving conditions.
I suggest you get your auto parts from another, more reputable company.
