Great Stuff! Sounds like a weekend you won't soon forget! :thumbsup:

I may represent that remark.

Give some serrious thought to the type of car. Durability is more important than speed. Miata's are tough little cars. Their weak point is the diff though. There is a fine balance to making them last and a lot of it centers on the motor and driving style.

A built motor such as those from Robello will do fine for the usual Spec-Miata sprint races. Probably not going to make a 25. Twisting the thing to 6800 also not a good idea for the motor and it also sends a big hit to the diff on every shift.

What type of car are you considering?
