New hosts, be mindful of stopping cars

BlueLineRacing Thursday, 1/25/2024

Jump to last page

I want to thank everyone who ever took the time to host a race but I have noticed recently some cringe worthy attempts to stop cars at the end of the track. With this in mind I think I speak for many in asking you to find a safe way to stop cars. A good stop bag would go a long way in helping that effort. 
Some of these series take months to start. Months to finally finish and there is nothing worse than putting all that work in on a car and waiting for it to finally race only to have a wheel bent or have an axel break loose due to a poor stop situation at the end of a track. 
I ask to please keep this in mind when hosting. These cars are heavy and fast and can't take the beating that your traditional 30g stock car can. 
Again I appreciate the effort and know the challenges of hosting races but respecting the time and effort that goes into racing is a two way street.

So, just for clarification... what are acceptable methods? I see cars crashing together after hitting the end stop... some kinds of bags filled with something? Not sure what the best method entails... don't have a track yet but looking for suggestions.


  • The most common method I see are bags with towels over them in a pile at the end, or you could use styrofoam tubes — Kingjester
  • Probably anything that doesn’t involve a solid wall — Crazy_Canuck
  • I've used a rolled up towel, open carpet so they just slow down on their own. (space needed though) Currently I'm using a piece of copper pipe foam wrap. Pool Noodles also work. — Vern01

The long, steep, drag tracks in Puerto Rico and Indonesia have some blistering finishing speeds. They appear to use foam padded boxes that separate the cars as they finish.

Open track is another story. I'll usually try to quickly clear out my OT stop box by hand as cars enter it. But there are always those close finish situations where the cars are rolling nose to tail and a collision in the box is unavoidable. I've had plenty of chipped paint and broken plastic parts in my OT stop box. Then again, OT racing is a risk in itself.

Yeah, I'm new but 100% agree with BlueLineRacing. I've been cringing seeing people's racecars fly off the end of a track and crack into each other lately. 

Again, I'm new but I'd also like to add:

Using competition racecars, for "fun" outside of the stated race, especially things that can challenge their race readiness, is not cool. 


  • Though I'm a relative newbie, I've thought about sending my car(s) as late to a race as possible to avoid the hosts just running cars for fun before the event, and then adding a different lube to my entry to compensate. I'm no alchemist (yet) but I know that most everyone has their ways and means of optimization of their particular vehicle for that specific track, and I don't want someone gumming up the work. — RayRaySugar

There is a small collection of topics about stopping blocks and catch boxes, might give folks some ideas on how they can manage cars.

My drag strip was not very long so the impact was pretty minimal, but I used a bag of rice wrapped in a towel and it always worked great. Cars would bounce off of it or slide to a halt without any problems. I've used the cushion foam too and had good luck there...they'd just hit and bounce back. Now thinking, that was probably the material that yielded minimal impact on cars.

I experimented with a raised part in the middle of the track beyond the finish line...stole the idea from pinewood derby where it's basically a shim and the car slides up onto it slowing them down more gradually than a sudden stop. It kinda worked but I just stuck with the stop bag for ease.

Although GSR brings up a good point about the open track races being more complicated...I've never thought about that having never had that type of track. Maybe having a soft material like a towel or foam that the cars roll onto would help in slowing cars down before they hit a foam stopper or something. I'd think just having a non-plastic material should slow down cars quite a bit for most tracks.

Oh shoot I didn't know this was an issue. I'll replace the concrete block I have at the end of our track hehe ;)


  • lol — Stoopid_Fish_Racing
  • Oh it’s an issue. Whether you take it serious or not is up to you. We sent you Super Treasure Hunt cars worth upwards of $30. I hope you take it serious — BlueLineRacing
  • I'm totally kidding. I'm pretty anal about making sure I have the best possible catch box to minimize any damage from cars colliding at the end of the track. — TinyTrackCars

I think I know of which you speak, and I winced when I saw my car go flying through the finish. I spent waaay too much time on one of my very first decent builds to have it compromised due to carelessness. Too, using a stop system that is lint free. No one want fibrous materials fouling the wheels and axels on their cars. That said, kudos to all the hosts who take their considerable time and money to host events, and then have the wherewithal to film, edit, and post the videos for all to enjoy. I can only imagine how difficult an endeavor it is.

A great reminder Blue Line Racing ! 100%

I see there has been some good input, also concerns from others as well.

There are many differing types of events one can enter, so make sure you know what you are entering, how to build for it, and what to expect!

Also good to check out previous events held at the track you may wish to enter at, ask around, get advice, and make decisions (where you can) based on your research.

But yes, at some events, the stakes are high, countless hours of car development, tech and or paint etc, so one like to see the builds treated with respect, for the type of event they are in. (Hehe, expect a few bruises at Junkyard Joust!)

Cheers good luck out there!

I agree, I've definitely cringed seeing what people use to stop the cars and would like to add that cars should also be protected if they fly off the track in open track races. Shit happens and something as simple as bubble wrap would be better for people's cars to land on than a bare piece of wood/concrete floor. 


  • "To infinity and beyond!!" Ouch ! Yes. — CutRock_R_Marc_D
  • If people only knew the effort and money that go into these cars. We are not YT props — BlueLineRacing

I personally use foam from a old couch. I cut a bit out of it so the cars go in and slow down. Then they come to a stop at the back of the cushion. Also a black cloth over it to hide it better on video just in case chase cam catches it. This seams to work really well to protect the cars at the finish line. Unfortunately on open road course like mine. Cars to bang into each other. And once in a great while get tossed off the track. Most of my floor is soft black mats like memory foam bath mats. So they land softer than on a wood floor. I try and take care of everyone's cars but paint does get chipped sometimes and I apologize for that.

Stop boxes that wedge the car onto the track can bend front axles. Im using fleece and a  rubber band. The car passes under the band and catches in a fold of fleece. Exercise mat cushioning under the track and finnish will prevent axle bends and dings.


  • interesting about the bands — dr_dodge
  • The rubber band(s) go over the fleece. Thin rubber bands that only hold the fleece in place and add some initial resistence. The fleece fold does most of the stopping. — Vulfgang
