First off, most of you have been hellaciously under-informed about Daytona Prototypes. The cars are actually quite quick (lapping about as fast as the old Kudzu Mazda SRPII cars from the days when Grand Am was the other prototype racing series) and are very fun to drive for drivers.
The large greenhouse is mandated by GARRA so that a larger variety of drivers can participate without hesitation because their helmets will poke up into the intake or some other such nonsense. It's also because of a large steel "hoop" cage that is designed to protect the driver in a crash (like what could have happened had Luis Diaz hit the wall in that spin today) and keep chassis from being total write-offs after one hit.
After all, a chassis that can be rebuilt is a chassis that will keep racing. It's much better than situations like that LMP2 Lola B2K this year in ALMS where the carbon tub cracked and was irrepairable and the cracks were the cause of too many miles on the same chassis. That team, by the way, is as I recall unconfirmed for Sebring as their sponsorship may not allow for them to have the funds to buy a brand new Lola, Courage, or Lucchini.
The suspensions on the DP's are quite sophisticated, and most of the handling woes come from restricted aero packages (to promote close racing) and from a spec sized tire (to cut costs). Again, cutting costs puts more cars out on the track and closer racing puts more butts in the seats.
The reason that chassis constructors are limited in number to the current selection of Fabcar, Riley, Doran, Crawford, Picchio, and Chase is to prevent the market from flooding AND to keep homebrew specials that are unsafe or unfairly constructed from entering. There IS a seventh Daytona Prototype chassis on the drawing boards - from Sabre - that will be allowed to compete should any of the currently active constructors cease production.
So, if no more Chases beyond the single constructed chassis seen this year at Daytona are built, Sabre will be allowed to produce and sell the Sabre chassis. However, a team that has a Chase will still be allowed to compete with a Chase so long as there aren't Chases being built.
Again, it controls cost, keeps steady production going (with a limited number of suppliers, a good constructor - like Riley - can sell 15+ chassis to eager teams whereas if there were ten tons of suppliers, Riley might only sell one or two).
And for the guy who said that these constructors have very little history, let's get a little history lesson on each. Here's some past cars from Riley, Crawford, Doran, and Fabcar.
- Group 44 Jaguar XJR-5 - designed and built by Fabcar, 1985
- Chevy Intrepid GTP - designed and built by RMI (Riley Motorsports Incorporated)
- Riley & Scott MkIII - the single winningest WSC chassis type in IMSA.
- Crawford SSC2K - as seen here in Lista/Doran colors. High-downforce privateer chassis of which an indeterminate amount (possibly less than five) were built. Project dropped due to lack of interest and picked up by the influential Doran team for further development. Car was then returned to factory where it competed in Grand Am for one year under Crawford factory colors.
- Mazda RX792 - Crawford constructed chassis; first all carbon composite chassis in GTP racing built by a non-aerospace private company.
- Dallara LMP 001 - While Doran's history as a constructor is primarily in club racing where they've manufactured tube chassis for Nissan 240SX's and 300ZX's, as well as SCCA Sport 2000 chassis, it's their success at taking abandoned projects and making them function that really shows their ability.
Followers of international motorsport will recognize this Dallara as the very same car that Chrysler commissioned from Dallara for their short-lived Oreca Chrysler LMP program. This program used threee Dallara chassis with Mopar sprint car engines to go head to head with the Audi juggernaught and failed with a succession of blown engines save for a stand-out 4th place finish at Le Mans in 2001. Doran purchased chassis #001 from Oreca and brought it to Daytona, fitted with the reliable Judd V10 (which had been so formidable in overcoming the drag of the Crawford SSC2K chassis). After seeing the meager budgeted Doran overwhelmingly dominate Daytona, and qualify tenth at Sebring after outfitting the Judd with intake restrictors (an ALMS rule) - though the car was taken out of the race in a crash - Oreca returned with two cars in 2002, now with Judd power, and finished 5th and 6th, then abandoned the program, leaving Doran with the sole competitive Dallara.
Doran went on to take a commanding championship win in 2002's GARRA season, and returned to Sebring in 2003 hoping to catch a Le Mans invite, especially as they finished 7th overall after qualifying 8th. The car was much more competitive in ALMS this year thanks to MG badging the Judd engine, causing ALMS to loosen the intake restrictions. In ALMS competition that year, Doran also scored a 5th at Road Atlanta (qualifying 4th, losing one place to the Dyson MG/Lola).
Despite clear success in ALMS and GARRA, the ACO did not give an invite to Le Mans to the Lista/Doran team. Seeing this, and having debuted their JE4 Daytona Prototype chassis with great success (first Daytona Prototype to capture an overall win), Doran shelved their Le Mans plans with the MG-Judd/Dallara and concentrated on their GARRA Daytona Prototype program. They captured the 2003 GARRA Constructor's Championship (their first year as a constructor).
So, while I will admit they may not have the storied past of Lister, Lola, or Dallara
, the GARRA constructors are certainly no slouch when it comes to putting together an American race car and have been around the block in IMSA for quite some time. I'd like to see Dallara, Lister, Lola, G-Force, and many of the other chassis companies become GARRA constructors. But only if one of the current constructors stops building cars OR it's proven economically sound to expand from six constructors to, say, ten.
