After a little over a year it is time to sell my NASA TT4 and ST4-ready Turbo Miata. Once the season closes this year it will be the 2021 NASA AZ Regional TT4 champion and holds a few TT4 track records. Currently on a tune that makes 222whp peak and 216whp NASA average to fit into TT4 with 100tw tires. Car is quick, very easy to drive, and has been dead reliable for me over the past year once initially sorted. It has a clean title. This car was previously raced as a S1 SuperMiata.

Cliff notes:
Built motor with BorgWarner EFR6258, 222whp flat tune / 216whp avg. Will support >350whp as-is.
Supermiata Xida Race Coilovers
BMW M3 CSL MK60 ABS (ST/TT4 Legal)
