I have a near new set of the TTT 300 mm Big Brake kit for the Datsun ZX front struts for sale. Less than 3000 miles of mostly highway and NO race use. Every nut and bolt and SS brake lines are included. While they work just fine, I found they are too big for the choice of wheels that I want on my 510. I had a set of Rota Grid V 15x7 that fit just, barely, but anything smaller won't go including most 15" and smaller Datsun alloy wheels. Retail is $995 USD, I sell for $995 CAD including shipping to Canada or the US. This is TTT's web page that fully describes the product for sale.
I went to the TTT new Micro Big Brake kit. Love it, fits just about anything. BTW the SS lines in the kit above are brand new, not the used ones I had on the car. I kept the lines from real BBK and include the new ones I got from the Micro BBK.
