With a little modification, the bumpers made for traction bars will work (slapper bars). You can also fabricate some spacers that will work.

That is what I have on my 1969 Dart. I limit travel to avoid excess wheel stand. I bought some nice traction bar bumpers and cut them to the length I wanted. Then on each track day, I put between zero and 0.437" of spacers under the bumper to set the amount of front end travel and weight transfer I need for the conditions.
A lower torque/horsepower car will want all the weight transfer they can get (short bumper), but a higher power car doesn't want to be on the bumper.
