Solo Rules

Drivetrain is virtually unrestricted, with the exception that the motor has to be from the same make as the car (Mazda). Fueling, transmission, rear end, etc. are unrestricted.

Areas of Focus

Axles

Stock miata axles with the 99 carrier swap hold up to a lot of power. ABS Rings part # is BC4C-33-471. ~34$ each.

Driveshaft

The 99 carrier swap will bring a new slightly shorter driveshaft. The stock one is 11 lbs, the MSM shaft is 14 lbs. At some point someone made a CF driveshaft at about 8 lbs, but it's not available anywhere that I can find. Probably not worth it to bother. :)

Clutch/PP

Spec stage 3+ (SZ453F) - 549$ from Spec, 495$ retail most places on the net

Flywheel

Stock flywheel is 20 lbs, claims FM.

JSC has a good overview of all the options as well.

Header

Emilio says to just use the Racing Beat 99 header -- I don't need a custom header at these power levels. 408$ from good-win-racing, 410$ from 949. Buying one of those for now. Will possibly explore custom headers further down the road.

Called Prather Racing about a custom header, they forwarded me to his son, Jesse Prather, 785-249-0284. Left a message there, waiting to hear back.

Exhaust

Doug wants about 1500$ for a custom 3" exhaust. Don't know how much for 2.5".

I emailed Emilio (949) about what to do for an exhaust with the RB header and he says: I'd suggest custom 2.5" or 2.75". Gonna be insanely loud. big resonator and a really big muffler out back.
