Quality Features:

Zimmermann brake discs are manufactured from high-carbon cast iron matching OEM material specifications. Each rotor is engineered to precise tolerances and undergoes rigorous inertia-dynamometer testing to ensure optimal braking performance and durability. The ventilated design provides enhanced heat dissipation during demanding driving conditions.

This brake disc is designed for vehicles without M Sport Brakes (S2NHA package). Rotors should always be replaced in pairs to maintain balanced braking performance. Proper bedding-in procedures should be followed after installation to achieve optimal pad-to-rotor contact.

Great service and product. A+!

great price. hope item is as good as the price

Perfect!!!

Muy bueno

It took exactly a week for the part to be shipped because the part came directly from the supplier. But the price was the lowest around.

the service was great quick easy checkout and a discount on shipping :)

Easy to navigate and detailed descriptions

I needed a few small XRP fittings for our NHRA Top Alcohol Dragster, I had called XRP and even a "pro racer discount" the price was ridiculous; couple this with their ridiculous shipping/handling charge I had to go elsewhere. I typed in the XRP part number into Google and found Autoplicity, twice as many pcs. as I was planning on ordering and with shipping it was cheaper than one fitting from XRP direct. I will be checking Autoplicity anytime I'm ordering something from this day on, everything about the transaction was smooth and simple. I just got my tracking number today and the stuff is on its' way. Thanks for making this transaction so easy and not robbing your customers on something as frivolous as "handling".<br><br>Respectfully,<br>Brandon Booher<br>NHRA TAD #34

Quick and easy.

I got a cargo box from autoplicity. As far as online purchases go to delivery, everything went perfectly. The only comment I have for Autoplicity would be to send out a confirmation email when the purchase is first made. The first communication wasn't until 3 days after I made the purchase.

GOOD

Ordering so far has been easy

Great prices on a lot of good stuff, shipping isn't what's listed in price comparison, but competitive.
