Got a track related question? I'll try to answer.

Any street pad is prone to fading on the track as their not designed to deal with the high temps that track pads are.

Well at 1/4 of the price of track pads I think I will try them out.

You're right, the HANS is not on the harness bar. It still is designed to work with a full five point or more system. Half-way is a bad idea.

It'll come down to brake management. With not-grippy Sumitomo tires, I'm fading them after a few laps, but I can usually go 70-80% in brake zones and they'll last a full 30 min. session.

If you have sticky tires or want to threshold-brake for a full session, you'll definitely need real track pads.

I run Hankook RS-3/Bridgestone RE11+suspension mods and didn't have too many problems with stock pads my first day out, but I was pretty easy on the brakes and never went 100% into the braking zones knowing I was on stock brakes. Its nice having stock power because the highest speed I saw was 144km/h which isn't too major.

One day I will be able to brake as deep as those damn Porsches...

Yeah you should be fine if you were ok on stock brakes. 144 kph is about 90 mph I think. One thing to keep in mind. As you get more experience, your speed on the straight will increase bc you learn how to exit the previous corner quicker. Keep an eye on your maximum speed at the end of the straight and adjust your braking as needed.

As I started learning one track better, I noticed my top speed in the straight increased from 96 mph --> 103 mph. As I started consistently hitting 103 mph lap after lap, I noticed my brakes started fading a bit more. Just something to keep in mind, esp if you're on street pads.

Yeah even on my first day out in 3 years I managed to increase my trap speed on the main straight from 138km/h in the morning to 144km/h by the end of the day.

Need to shake off that rust, hopefully we will have a road course near my city late next summer or spring 2016.

But it IS designed to work with two well-secured shoulder straps, which a four point system has. The HANS device can't separate from the driver, because the two shoulder straps are holding it in place. Which means it can perform its designed function. The lack of a crotch strap would only affect its function if the driver submarined under the belts and the HANS was no longer being secured by the shoulder straps. And the Schroth ASM harnesses have alleviated that threat.

I'm with you on this with one caveat: the ASM is designed to allow the body to rotate slightly in a collision, therefore preventing the submarine. I'm not sure how the HANS will respond to that twisting motion, even though it's not attached to the harness. I'd like to see video of the HANS on a sled with the Schroth ASM 4 harnesses. It looks like the video posted before was actually using a 5 or 6 point.

Do it once, and do it right.

Going from stock to Stoptech is like going from a 1 to a 2, while going from stock to a race pad, is like going from a 1 to a 7-10, depending on the pad

Problem is I may not even get out lapping another time for the next year, so its hard to justify spending 4 times the price on a set of pads I may not use.

But even though the inside shoulder strap is designed to give a little more than the outside strap, inducing rotational motion, both straps are still correctly located over the driver's shoulders. You would have to come away from your seat by a very large amount to allow the HANS to slip off, and the straps won't allow that.

It only takes 1 bad fade for you to not be able to stop, and have an off at the track.

Ultimately, if you decide you don't need the brake pads, race pads aren't difficult to sell used; it's a fairly linear depreciation with the amount of pad material left.

You carry auto insurance, even though you don't ever plan on using it, right?

This.

The pads aren't going to go stale if you take them off after track day and use them next year. I put a set of Winmax W4 on mine for track day tomorrow.
