The NASA Spec3 (S3) racing class is devoted to BMW E36 325 models. The goal for Spec3 is to create high levels of competition between similarly prepared cars at a reasonable cost. Purchase and preparation of a car for these series should be less than $15,000. Enjoy a race car that is great for HPDE and Time Trial duty while being built. Without the extravagance of ulta-exclusive and ultra-expensive parts, this is one of the best platforms to build upon while still being able to go out and enjoy a weekend at the track. Or for the experienced racer, NASA offer a competitive series that can be enjoyed for a fraction of the price of some other platform options.
What you need to know
Spec3 is similar to Spec E30 but for the newer chassis and a more powerful engine. With limited engine and suspension modifications allowed, Spec3 ensures close racing, while not breaking the bank due to a plentiful supply of low cost street vehicles to convert. A spec Toyo tire and suspension package take the guess work out of building a competitive car and the series platform has proven to be as reliable on track as any existing class. We are looking forward to another great season of NASA road racing. Thanks for your support and see you at the track!

This is one of the most economical ways to race a BMW in NASA. The Spec3 racing series uses the 1993 to 1995 BMW 325. It’s the most restricted series in NASA in terms of which cars can be used as donors, but because of that, it’s also one of the most competitive. These races are always close! If that’s something that interests you, find out more below.
The 1993 to 1995 BMW 325i and 325is are the two eligible vehicles for Spec 3. To make it easier to find and build new cars, any E36 chassis maybe used provided that all relevant components (engine, engine wiring harness, transmission, brakes, etc.) come from a 1993-1995 production vehicle.
