Nashin 135i/335i "380/345 mm Floating rotor, Mono-block caliper" BBK

The rotor's themselves are are made of a steel alloy which has been specially coated to increase oxidation resistance, hence the unique colour of the rotor surface. Both front and rear rotors are heavily ventilated (with the front being curved vane) and have of thickness of 34 mm and 28 mm respectively.They can also be supplied "cross drilled" if you desire, but we do not recommend this option for the serious track day enthusiast.

The front caliper is a N-series 6 piston monobloc unit, that is cast from aluminium alloy, it was supplied with Nashin's "Sport version" pads pre-installed. The rear caliper is also a N-series monobloc unit, but it is a 4 piston assembly utilising the same "Sport version" pads.

The brake pads are available in 3 different "flavours", Street Sport and Competition. The N-series callpers themselves are available in 10 different colours.

The below image illustrates the 3 pad compounds that are compatible with the Nashin calipers. The service life of both Street & Sport pads are quoted at 15,000 - 20,000 km. The Competition pads are quoted at 10,000 km.

N.B. the pad life I have quoted above is based upon spirited driving, it's NOT indicative of normal street use.
You could expect as much as 30,000 - 40,000 km from both the Street & Sport pads under normal driving conditions.

The operating temps of the Street & Sport pads are 50 - 550 degrees Celsius and 50 - 650 degrees Celsius respectively. The Competition pads perform optimally between 270 - 800 degrees Celsius.

The pad dusting level is quoted as being low for Street, low to moderate for Sport and as you would expect from a Competition pad with a lot of bite, dust level is quite high.

One of our shop-cars a 335i is running Sport pads with the above BBK, from what I have seen the dusting of the wheels is not that bad at all, so for those guys that option up Sport pads I suspect wheel maintenance will not be an issue and even less of a concern when using Streets.

Here are a few more pics I took of the entire "Nashin Big Brake Kit" during a close inspection and clean up (hence the scouring of the rotor face) of the brake system, following a recent track day.

FYI,

The last pictures our of the front brake system underneath BMW OE 230 19" wheels, that are on our 335i shop car.

Whilst the front caliper clearance is minimal, we found no evidence of any rubbing/scoring of the inner wheel or caliper assembly whatsoever, during the course of the event.

Lastly the BBK includes all the necessary high strength mounting brackets and fasteners for both front and rear rotors, as well as teflon lined brake lines, that are sleeved with a double layer of stainless steel.
