My track has a short shut down. 4 foot 6 inches. This isn't a problem for me unless the cars run less than a second on my 15 foot 7 inch timed section.
The highest voltage I run is 18 volts. If I am worried about the speed of any cars I simply put a towel at the very end of the track.

My track is pretty short in the shut down area also. It is 15' 7.5" long and I mostly run at 20V even the 60 mph cars run at that voltage. I use dynamic braking for the first 2.5' then 3' of metal stop strips which are 2 1/8th inch steel strips screwed down on each side of the track followed by the last 6" with a catch box which is padded with foam. The foam is cut into a V shape with pads all over it. I have stopped cars at over 60 MPH with this setup and the worst damage was a body getting knocked off. Don't get me wrong the 60 mph cars hit the box pretty hard but I make sure those cars have well mounted bodies. The first time I ran one of the very fast cars it went right thru everything under the catch box thru the final pad and hit the wall pretty hard. FYI dynamic braking is just shorting the dead strip between the two rails letting the motor act as a generator.  Metal stop strips

Bear Creek Dragway is 1/64 scale 1000' or 15'7" timed with just over 3' of shut down. I am only using dynamic braking and a "bullet catcher" catch box. Box has a base layer of dense foam at the back wall followed by soft packing then a series of rolled up towels to help slow cars. I have run cars at 26v in the low .4's many times with no issues. I have to really pay attention to the towel placement....more shut down would be preferred if you have the room.
