I crewed for the #40 Spec Miata E3 winning team, 12th overall.
The team beat all Mazda cars, including Catfish Jackson Racing Rotrex Supercharged, all 4 NDs, and both MX-5 Cup (NC) Miatas, as well as the rest of the Miata(or any Mazda) contingent.
The #40 qualified at 2.05, but went 2.04 on previous occasion in the same specification.
Weight was 2400lb including driver. Tires Hoosier 205/50x15 R7s.
Typical spec Miata, not a premium professional build but a small enthusiastic team build-effort.
Interesting tid bits, for us who endlessly turn to "tuning" (modifying), this car is slower on 225 and larger tires than on 205, because of its limited power!
Adding power thru NA or turbo/SC tuning, gives modest gains in lap times.
Its interesting how small the difference in laptime is between say Spec Miata and SuperMiata, despite SuperMiata having Aero and tire-size advantange, and power to weight ratio advantage (possibly countered by wider tire drag and aero drag).
Say at Laguna SuperMiata can in ideal conditions do 1.43, and SpecMiata record is 1.44.
It seems that something like PTE Miata and Spec Miata, are quiet an ideal balance of value and performance: in the rain(Which lasted for 1/2 the race) the #40 was often faster than E1, E2, cars, (Bmw M3s 330is, and more).
