MR33 proudly presents their new “V4” version of indoor tire additive. The additive has a new formula and will help a lot to build up the groove on carpet very quickly. This will be noticeable on big events where new carpet is used all the time. The new additive performs very consistent during the run and has a nature base without any chemicals inside! It will be delivered in 100ml bottles with a sponge applicator as it is well known from the previous versions!
