Silver Mine Motors (SMM) originated as a performance brake upgrade company. We manufacture high quality and reliable brake upgrades for race applications to daily driven vehicles. We strive to set the standard for customer service to all our customers. All our parts are for off road use. Not recommended for use on any public roads. 


Our mission is a long term model. We believe in providing excellent customer service before and especially after a transaction. We strive to uphold our excellent reputation in the auto industry for many years to come.


Silver Mine Motors was founded in 2006. Our mission is to provide the Z Car industry with affordable brake upgrades and superior customer service. 

Since then, we have extended our market into the Nissan S13, S14, 280zx, Datsun 620, 521, 510, BMW E30, BMW E36 and Lexus SC body types. All of our brake kits are made of equal or in many cases much higher quality than original parts and material. We use T6061 Aluminum for all custom made Aluminum parts and 1018 cold rolled steel for all custom made steel parts. The average steel hardness of factory original steel brake parts is around 4, while we use nothing less than 17.

We stand by our products' quality and performance 100%. We design our brake kits to last through extreme conditions. Our brake kits have been used in Targa Canada, circuit track racing, and drag cars. 

Our brake upgrades are sold to every developed country around the world. We have strong connections and sponsorships with international professional Z Car drivers and enthusiasts.

Return Policy

Due to the nature of the products we sell, we do not accept returns on any hydraulic brake parts. All other non hydraulic parts can be returned with a 30% restocking fee. No returns or exchanges can be made 90 days after sale. No exceptions. Buyer pays return shipping. Original shipping cost is non refundable. International orders might take 1-6 months to arrive. We will never re-ship products a second time if they do not arrive. No refund can be given until after the insurance claim pays SMM for missing parts and shipping. No exceptions. 

Shipping Policy

Brake upgrades will usually ship in multiple packages. Some packages will arrive as soon as one week before the last package. 

Note about cars made in the 1970s-1980s 

We have realized that no two cars are exactly the same. If we make a brake upgrade that fits on our shop's 240z or Datsun 510 there is a chance that it will not fit all 240z or Datsun 510’s in the world. We have found that some cars have a 1/1000 of an inch difference. This means some will need to add a shim to make the caliper be centered inside the rotor and some might have to grind down the caliper bracket a little to center the caliper onto the rotor. Silver Mine Motors will not pay to have this work done, but we will modify our brackets for free if you send them to us for modification. We can also send shims for free.
