99% of carpet tracks in the USA use barriers in a similar style. Nothing wrong with curbs, but this is they way they have always done it.

Don't you US drivers think it would be an idea to change this? Are there no moves to try and change this to something more car-friendly and something that would improve the racing? Must say I have always found it hard to understand why you use this system...

Well you don't need concrete to make "curbs" that work well. Wood, plastic or metal works really well if they are well made.

I dont see anything wrong with our system. If your good, you can run tight to the tubes and dont need the "cushion" area you get with a curb. I think they call that space perception?

This square pipe is available from Orchard Supply Stores for about $4 per section (10' long?). Stockton and Gilroy use it for their carpet tracks.

Hi Leini,

The use of the PVC piping as barriers is really kind to our cars and can also eliminate many instances of hacking created by jumping curbs. Pre-made rounded corners of varying degrees made of strips of PVC with sections of square PVC sandwiched inside can have a certain amount of "give" to be friendly and forgiving. PVC is lightweight and easy to reconfigure.

And we have a lot more potential to change track configurations because we are not limited by fixed curbs either.

How do you fasten the 4x4 PVC to the carpet or hold it in place?

Thanks
John

Industrial velcro. Comes in 2" wide rolls by 20-25' long. Cut to 4-6" pieces. Take 3-4 pieces to hold down a 10' length of PVC pipe.

Santa Cruz uses wood 2x4 construction and flexible bender board for the teardrop/corners.

Default wood track walls

i like the 2x4 (wood) walls cause one hard hit could break the car just like in real racing. you hit a wall with a real race car and it's done for the day. anyway, the 2x4 walls also help prevent cars from jumping lanes. if we put curbs out there the cars would be jumping the lanes all the time. best thing to do...keep it clean and don't hit the walls...

I assume you are talking about something akin to an "island" system, where instead of a wall-like barrier you have a gradual slope to define the barriers of the track. Much like the Tamiya USA track, or where the worlds were recently held.

These tracks are nice, but they aren't very practical for indoor carpet racing. Scotty Ernst made islands out of industrial foam for his track, and had them shaped, shaved and painted to look just like that. They worked, but there were a few major problems with them:

a) You become very limited in track design; either a few basic layouts, or build more islands
b) Drivers suffer less damage for hitting the curbs, so they typically have no qualms about running on the slope briefly, or even shorting the track
c) The wear on these pieces can be heavy, especially when marshals inadvertently step on the islands

In the end, the common barrier system like the one used at this race actually works well, allows for many adjustable layouts, and really doesn't break the cars too much.

Curbs would just launch the cars into the lanes of innocent drivers. The Road Rails system is like that and is frowned on alot for that very reason. Carpet racing doesnt have the open areas between lanes for curbs to be practical. I like the tracks that use a wall system and have dots places in the corners I think its the best comprimise between both systems.
