B9 3.5 _x000D_ _x000D_ HD type _x000D_ In pursuit of higher stability _x000D_ The heat treatment stabilizes the bonds between the elements in the structure of the cast iron This prevents disc distortion and strain which is common immediately after installing new discs. _x000D_ The treatment also optimizes the surface hardness, which improves brake response. _x000D_ Higher performance can be achieved by using the HD discs along with the Z type or R series pads. _x000D_ We recommend this disc for advanced drivers who require / want more braking stability Compatible Vehicles:.

| Remarks | The heat treatment does not directly improve brake performance. The heat treatment increases the disc resistance against strains and thermal cracking. It also helps maintain stable brake performance for a extended period of time. _x000D_ The surface of the heat treated brake discs has a burnt colour. Once it is used, the burnt surface will be removed by the pad, and changes back to the colour of normal cast iron. Please be aware that the effect of the heat treatment of the disc will not disappear even if the surface colour changes. _x000D_ our processing of the rotor is, we have shipped in the above package.

Nice sound deadening, self adhesive mats
Style: 18 Sqft 80 mil
These mats should work fine for my application. I’m applying it to the back sides of the hollow core doors on the closet where my HVAC is installed to reduce the “hum” from passing through. If I were sound deadening my automobile, I would probably use a heavier gage material. Overall, good product at a reasonable price.

Works well and doesn’t break the bank
Style: 36 Sqft 80 mil
Awesome value for low budget wound deadening. Used this under the floor mat on my international 4300 and there is a noticeable difference in sound inside the cab.
