Hi Robert, I can probably put it in a nutshell.
PRO-3: More open suspension allowance (no remote reservoir shocks allowed though), min. weight 2,650lb, ABS banned (starting this year), uni-chip allowed. Spec tire Toyo RA1 tire, 225 width allowed.
SpecE30: Spec Spring/Shock, weight 2,750lb, ABS allowed(?), stock ECU, Toyo RA1 tire, no wider than 205.
The Pro-3 (Production 3) was started in 2003. We had 4 existing cars in ITS trim and wanted to start a spec class. If we had known that Carter was ramping up SpecE30 we would have probably compared notes with him and looked at detuning the suspension to what SpecE30 has. But we literally had 4 owners with existing cars and if we tried to detune the cars too much, then they wouldn’t have agreed to start the series. So the compromise was allow the suspensions to stay on the cars, but remove the hot cams and MAFs that a couple of the cars had. Thus Pro-3 was born.
Last year Pro-3 ran 13 races and averaged 10 cars per race. 95% of the cars are located in Seattle so the Seattle races had the highest entries last year with 15 Pro-3 entries. More cars have been built over the winter so we think we’ll easily see over 20 cars at the May Seattle race. At the end of 2006 there were 21 Pro-3 cars that had entered at least one race that year. Actually there were 23, but two were written off in crashes during the year. So right now there are 21 accounted for with 14 more being built. Some will make the May Seattle race, the rest will come on line during the course of the year.
We voted to eliminate ABS for 2007. It has been somewhat controversial. The debate is between saving tires by not worrying about flat spotting, versus requiring the drivers to have that added skill of being able to modulate the brakes in the braking zones without any artificial aids like ABS.
Pro-3 has no aspirations of growing outside of the Pacific Northwest. We race in a sanctioning body called ICSCC who run a 13 race series at tracks in Portland, Seattle, Spokane and Mission BC. For anyone who has tried driving to Seattle from other parts of the country, it is a LONG drive.
I think it is great there are so many E30s being raced in spec series. Aftermarket vendors will be more inclined to keep E30 parts on the shelf if they know there are enough of us racing an E30. It is the perfect (semi)low budget racer.
Street E30s are now a hot commodity in Seattle due to all of the guys looking to build a Pro-3 car and looking for a solid donor car to begin their project.
cheers,
Lance
