Forum member choneofakind is rebuilding a water-damaged 1999 Miata 10th Anniversary Edition for track use, working through an NB2 engine rebuild, a Teves MK60 ABS swap, a Keisler rear axle conversion and a cooling system redesign. The thread is an ongoing build log with detailed back-and-forth with other forum members on component choices, and as of the latest posts several systems are still being decided rather than finished.

How it was done
Background
The car is a 1999 Miata 10AE that suffered flood damage and is being rebuilt by its owner, choneofakind, as a dedicated track car. The thread documents an NB2 engine rebuild alongside chassis and system upgrades, with the owner comparing notes with other forum members doing similar work.
ABS and brake sensing
The owner is fitting a Teves MK60 ABS unit, having reworked a published 3D-printed mounting bracket design to clear the NB firewall, moving the ABS pump position forward compared to the original design. Rear wheel speed sensing uses stock NB sensors with Dorman tone rings pressed onto non-ABS axles, while Keisler-sourced MR2 Spyder hubs supply front wheel speed sensing.
Plumbing work in progress
The owner is struggling to source a factory rear brake hardline and may end up fabricating one from bulk hardline. New fuel lines have been ordered as part of a planned conversion from the factory returnless fuel system to a return-style system, to be tackled alongside the brake line work.
Cooling system still undecided
Considerable discussion in the thread concerns how to route oil and coolant, including whether to add an oil cooler, with the owner weighing cost, weight and leak points against interest in fluid temperatures. No final configuration had been settled in the posts shown, and the car remained on the workbench rather than reassembled.
Body and crash structure
The owner replaced the factory plastic front bumper beam with a Doriyoku crash bar, while retaining the car's crash structure, and has stitch-welded some structural parts. He notes caution around SCCA TTB class rules regarding removal of safety structure for radiator ducting.

Worth knowing
- Thermostats proved reliable across many miles, reducing concern about choosing a less serviceable remote thermostat layout
- Overlaying and nudging an existing 3D-printed ABS bracket design was quicker than designing one from scratch
