Just got done with a few morning sessions. I used my left knee quite a bit on the downhill corkscrew at VIR South. And I'm still on stock tires/suspension.
CG-lock and knee padding are on my shopping list.

I'm planning a BRZ built right now and contacted Schroth about their products, as I've used their Rallye 3 in previous projects.

SCROTH's US distributor does NOT recommend Rallye 3 in the 86's!!
Jeff Paulk got back to me pretty quickly, but this was his reply:

Hi Michael

Thanks for your email about looking to do Schroth Belts in your BRZ. ...
On that car you really need to do a harnessbar and our Rally Cross belts.
Your project sounds great ... Let me know if we can help you out if you find a harness bar.

Thanks
Jeff

Also, looking at the link you provided, it appears you have the Rallye 3 mounted incorrectly.
If you are going to use them, the belts really should go through the headrest bars, not around them, to help hold them in place in case of serious impact.

Not flaming, just posting this as an FYI as safety items are so critical to get right.

We use the Essex Harness bar and Takata (Shroth) "Race 4 Bolt" belts with an OMP Pista seat.

Essex may not claim it to do so, but it stiffened up our chassis and they're quite precise. Bar is bolt in and fitted within 1/16"

Rear seats still fold down and 4 race tires can still fit in the back.

Assuming it's a permanent install for HPDE purposes:
If you have a harness bar it's safe to assume you're running harnesses.
If you're running harnesses I hope you're using a fixed back racing bucket.
If you're using a fixed back racing bucket and get into a roll over, your body is forced to remain perfectly up right while the roof above you is subjected to crushing forces. Not a good day for your spine. This is why it's smart to add a roll bar when doing seats/harnesses, not just a harness bar. A roll bar also makes for good attachment points for a harness bar.

A full cage is not necessary, nor desired for any car driven on the street. You can bang your unhelmeted head on one of the overhead bars and it's lights out.

A stock vehicle is designed to soften the blows of impact during a crash. Your body is allowed to conform around the 3 point belt, because you're expected to be cushioned by air bags.

Oh and I wouldn't run harnesses without a head and neck restraint. If you fix your body in an upright position the only remaining part that is free to move forward in a frontal impact is your head and neck, subjecting you to a basilar skull fracture. Head and neck restraints are now required in I think both SCCA and NASA racing.

This all may seem like overkill to someone not familiar. It certainly did to me, before I researched it.

Here are the configurations I would consider safe:

1) Beginner to Intermediate HPDE: Stock, wear a helmet
2) Intermediate to Advanced HPDE: Roll bar, 5/6 point harness, fixed back racing bucket, head and neck restraint, helmet (swap in the seat only for track days)
3) Wheel to wheel racing: Full cage, 5/6 point, fixed back, head and neck, helmet, fire suppression, fire suit/gloves (all required for w2w racing anyway)

Personally, I don't think I'd be this cautious for autocross because of the lower speed and zero traffic. I hear there have been rollovers in autocross before though!

i'm doing #1. what are my options for additional safety? i don't use anything for neck currently. i'm tall and used to turn around the top part of the seat to give my head some more freedom, until i determined it was way way too much freedom if i hit something. it seems like i should at least add some kind of neck collar if i keep doing #1?

as far as #2 is concerned, or options available for a track/street car, i like this advice - although why the seat swap? if the concern for fixed back seat is a roll cage, it is provided in this example right? i thought the greater problem would be hitting head on cage (even padded) in the event of an accident. (??)

is there no great solution to just put in the car and leave alone for street and track driving?

[Sleepless]

IMO you don't need fixed back seats. You can use the stock seats if you have a rollbar that supports them (does not get in the way). I have Recaro Sportsters which I believe is what you'll find in the JDM STi as well as other high performance cars.

People who work at McDonalds know its bad for you, yet they sell it to you.

Lesson one in capitalism: Where there is a market for a product, there will be a supplier of said product.

Ahh, brings me back to the TRD strut stabilizer discussion. Those were good times.

Yet the people at McDonalds don't say, "don't eat this, it's bad for you." And my mans said, "for your safety do not buy this." And then sells it

Running a full cage in a street driven car is a ludicrous idea and I'm surprised you guys would recommend it. There's no better way to have your head pop like a watermelon than to have a street accident and bounce your skull off a steel bar!
