Was that top not bolted down? They don't pop off when IT and SM guys wreck.

It just had the front latches and Frankenstein bolts. The guy was borrowing his buddy's hard top when he wrecked.

Good to know, I was unaware of that.

So I'm 6'7" and have done 2 HPDEs so far in my Miata.
Mid-Ohio and Summit Point

I did 4 things.

1. Put in a M1 Harddog Roll Bar - the NON Hardtop version

2. Bolted a Kirkey 20degree (this is the slope of the miata parcel shelf) economy seat directly through the floor. I used a cutoff wheel to cutout around the seat humps, so I can still go back to the stock seat. (20 degrees is the slope of the miata parcel shelf)

3. Installed an I/O Port seat back brace to my AL seat ( required for safety)

4. Installed Hardtop using bolt in brackets. These are required for racing anyway, and it allows you to use the non hardtop version of the hard-dog roll bar- you gain ~ 1" over the hardtop version, and it fits just fine under the hardtop. The new version is just for the latches to fit.
The Hardtop is a big help because it reduces the number of questions people have at tech. they just pass you.

Bonus changes. This seat is super uncomfortable, its flat and makes your but go numb. To fix this I created my own "Sparco Seat Bump" Using a water noodle from Wal-Mart that is cut to my seat width and then zip-tied to the leading edge of the seat. It is covered by the kirkey seat cover so it looks less ghetto that it sounds. Makes a really big difference too!


Anyway, I've got the car still, and getting ready for another season, if this thread still has some interested people, post up here and I'll shoot some pics of my setup.

Later,
Adam
Any pics of the set up

and for steering I run a 280 mm Momo team Wheel on an 80mm quick-release spacer.



As you can see in the pics, I'm still a "bit" over. Thats where the hardtop, comes in. It keeps that hidden.

Nice. And ouch that seat looks like it hurts. There's no padding beyond your noodle in front and the thin layer of the cover? That covers just for looks, isn't it? I didn't think they had any padding.

They are usually padded, but I guess that one might not be since he put a noodle there.

The kirkey padding as far as I know has a shape similar to what he is doing with the noodle.

Its certainly an uncomfortable ride. But you know, on the track you're so focused you don't mind.

On the transits to the track, however , I use a thin pillow and its bearable. Thin because I like to keep my head below the roll bar while on the street.

Its a bit of a sacrifice, but to me its worth it to be able to drive a Miata.

You short guys don't know how good you have it !!!! ha!
