Stunt fences and Apex barriers

There are a lot of props to choose from that can mark the apex barriers. Some barriers that I get see used often are standard tire stacks. Just browse through the barriers category and find one that you like and think is suitable for the track.

As for getting fences that go along the track I recommend using the barrier stunt track props. Get the track itself to sink into the tarmac or whatever so that fences are only visible, you can do this by heading in to advanced options > edit prop position > ticking the box that says "overide prop position" > and then adjusting the z axis down. This is a trick that I use when creating my own tracks. 

Your best call is to race some quality NoDo tracks and see how these creators go about it. Check out some tracks by Skirakzalus for example, he makes good apex and track barriers.

That's one of the best advice for you Helmax

Thank you all very much

Best way to get barriers imo is by using the stunt tracks with barriers along side, but sinking them underground using the advanced options menu so that the track part isn't visible anymore.

As for the whole sticky prop thing, I find that keeping them as vertical as you can helps. For the pipes as well, the hitbox for the bits with the holes does seem off, so if you use those as an apex barrier, just keep the solid frame at the ends if you can.

It's a stunt tube, but the hit box of those is messed up.

I am a HUUUGE advocate for minimal use of stunt props. Blade pointed out the hitbox issue. The last thing you want on the racing line is something that you MAY or MAY NOT hit. If you want to put the stunt walls on the outside of a corner, somewhere not on the racing line then sure. But for the apex, use something standard like a *gasp* striped barrier!! It's consistent, it's visible, and it does its job the same way 100% of the time.

I hate to sound rude but seems if Broughy actually played the game he would realize this issue and stop advocating so hard for the sunken pipes as apex barriers. They are severely flawed in the functionality department with the hitbox inconsistencies. This is also not to mention that the raised middle shape obscures your view of the end of the prop in some situations. It's simply not the ideal apex prop. Use a non-stunt option, like the striped barriers or the fuel tank Skira mentioned.
