An Opportunity from Datsun

Back in 1969 we were given an opportunity from Datsun to prepare a PL-510 Sedan (and a four door at that) for F.I.A. competition at the Daytona 24 hour and the Sebring 12 hour endurance races.

Wins Too Numerous to Count

With wins too numerous to count (including national championships) and track records coast to coast, it is apparent that Jeff must be doing something right.

Knowledge & Racing Experience

Jeff’s goal is to help you have as much fun and enjoyment with your car as possible whether it is meant for the street or the race track.

Jeff’s expertise & vast Datsun knowledge & experience was, &
continues to be,  invaluable. The motor performed flawlessly for 4 race seasons. I freshened it before season 5, (bearings, rings, gaskets, etc) and there was virtually no wear. In fact, I could have easily put it back together as is, & run it for many more seasons.
Mark Robinson, 71 510 vintage
Jeff built both of our racing 240Zs, and currently provides outside maintenance, repair and improvement services. They are extraordinary cars, both mechanically and cosmetically, with considerable racing success, and I say this as a man who owns 16 race cars, and has raced on and off for over 40 years. The Zs have been fast, safe, well-handling and reliable cars, and are a blast to drive. Jeff has my highest recommendation – and much appreciation – for anything Z or Datsun related.
THOMAS J RAGONETTI , 240Zs
Jeff has been doing engine and other work for my 510 race cars for over 25 years (Improved Touring and H Production). He builds great engines, is always responsive, and has been supportive of all aspects of my racing. I strongly recommend Jeff as a race car builder and as a friend.
Gregg Ten Eyck, 510 race cars
Jeff offers a complete automotive performance program in house with quality craftsmanship time and time again! He is knowledgeable at the track or in the shop with decades of experience as a driver, car builder and SCCA champion.  Rallye-Sport is easily one of the top five shops for custom street production / prototype based race cars.  I do not very often recommend a shop, but I am happy to do so for Mr. Winter.  Thanks so much for your support and patronage over the last 25 years.
George M. Ibbotson, Road Racing Services Inc
26 wins, 16 lap records, 14 different tracks across the country, American Road Race of Champions ITS winner, what more could you ask for?
Nick Craw, SCCA President & CEO, ACCUS/FIA President & CEO
Speed, reliability, safety, integrity. That’s what comes out of the Rallye Sport shop. Oh yeah and wins. lots of wins.
