The big boys do it,anyone here have it figured out?
Thanks

What kind of info are you looking for and why do you want to do it? Only reason the pros do it is because we have to have driver changes completed in 30 seconds. Most club racing has a 5 min. minimum pitstop which negates the need for the tethers on the belts.

We do enduros which is limited by fueling (no minimum time we are set at). We drilled out the filler tube so we can fill up the cars much quicker now. There was talk of us doing this as several other racers in my group are doctors and have access to the surgical tubing. I wouldn't mind it even for when I'm not doing an enduro as it simply makes it easier to belt up and unbelt b/c they will be suspended in a much easier to reach area (I guess if you do it right).

my lap belts are litterally tightly zip tied on, makes getting in easier as th belts are always out of the way

from what I have heard, just use a hot glue gun. nothing super hardcore to attach the surgical tubing.

Juan Lopez

The surgical tube is tied on (at least on my old pro race car - 993 RSR).

We are planning on doing this in the LeMons car. We have gotten our pit stops down pretty quick, but that is something we always fight. When I saw Ganassi's cars during a tour, looked pretty cool. One of the next things on the list.

I used zip ties to form the loops at the tube ends, works great!

There's no real science to it, it's whatever works. A zip tied loop to the adjuster will keep the lap belt out of the bucket so you don't sit on it and is real handy for tight seats, the shoulders can wrap around the top of the seat through the belt holes. Just make sure they don't shoot off to the back of the car so you can't reach them. Practice a few changes and it will tell you what needs to be done.

What would you need a hot glue gun for?

Also, the race supply companies have black tubing that does the same job as surgical tubing and looks nicer IMO. Some of the belts designed for endurance racing already have looks for attaching the tubing to. Every car is different as to how/where to attach...depends on your cage, your belts, your seat, your reach, etc. If you can't find an anchor point in an area where you need one, I have seen folks epoxy small anchors to the roof of the car, etc. Be careful about making the tubing too short to the point that it's hard to tighten the belts correctly. It takes a lot of adjustments to get everything "just right."

If you have window and left/ride side nets, the tubing can also be used to pull them back and out of the way.

They're called Penrose drains:

Nah, that's not the stuff race teams are using. The stuff race teams are using is more structural and seems to be more commonly called surgical tubing. Here are a couple sources:

Ahhh. Yep, definitely different and I can see how the thicker tubing is better (to hold up harnesses).

However, as a side note, I'm not sure what is "surgical" about that tubing... I can't think of a single thing I use in the O.R. that uses that thicker rubber tubing (except maybe a blood pressure cuff?)...

Bryan Watts

It's probably "surgical tubing" only because it was invented for some sort of use in surgery many years, but seems to be used for 1000's of other things now.

JClark

I'm sure if we all put our heads together we can figure out how to affix tubing to harness belts.
