PETE BROCK'S BRE DATSUN ROADSTERS WERE HIGHLY DEVELOPED, AND UNDERWENT MANY HUNDREDS OF HOURS TESTING. THEY INCORPORATED THE FOLLOWING FEATURES:

• A front air dam, incorporating scoops, cunningly disguised as brake ducts, which Pete Brock marketed as a SPOOK^TM, (an amalgam of spoiler and scoop). The 2000 Roadster was the first production race car worldwide to feature an air dam. 
  PB:- "Most people thought we were mad 'cause they were so ugly! But they did the job. Under the rules no such device was allowed, but "brake scoops" were permitted. My brake scoop design ran right across the front of the car and complied with the letter of the rules so it was permitted! Later everyone began to copy the idea and then they began showing up on the street. The rest is history".

• An oil spray bar, which lubricated the cam followers and which Pete Brock termed an oil cooler. The legality of this hardware was not known at the time so the team protested against themselves, a first in SCCA history, to allow the scrutineers to determine whether the spray bar was acceptable. The scrutineers agreed, and the modification remained. The Nissan factory incorporated a similar spray bar into the production 510 shortly after.

• The BRE C Production 2-litre engine in its final form was estimated to produce 185bhp at the flywheel, a testament to Art Oehrli's engine building skills. (The compression ratio was increased from a stock 9.5:1 to 12.8:1). Back in 1968 Pete invested in a Heenan & Froude dyno, which he still believes to be one of the best in the world.

• Venolia forged domed pistons, previously popular in drag racing.

• Weight saving items such as a British aircraft battery, and a high-tech plastic clutch scatter-shield.

• A full tubular roll cage, built into the tub of the roadster.
