Firm open cell foam inserts for use in Exotek Twister drag tires in place of the air valve system.

Larger foam in a firmer compound to fill out the tire and reduce tire folding in high grip situations.

If these foam inserts are used then do not use the air valves. Remove valves and leave the holes in your wheels for proper venting.

1 pair of Firm foams.
