    R compound prep

    Going to be going to autox on the 18th with madforce10 and this is going to be my first time using my Hoosier R6's. They need a little softening, so after talking with John he said to look up some home brew tire prep recipes and use that. He suggested straight up kerosene and after searching I found a bunch of different recipes. I found this site that has all different ones and gives the situation for each, like slow prep vs at the track. I'm going to start doing the 1 part mineral spirits/2 parts diesel probably on Saturday or Sunday as that will give it a week of prep.

    I don't think we have too many autox peeps on here, but what do y'all use for tire prep? I know I could just buy some prep, but whats the fun in that when I can make the one I'm making for like $5? lol

    Most circuits for auto x can be so short you won't get enough heat cycles in before the day is done.

    Maybe check out frrax, and ask there.

    John suggested potentially driving to the event with them to get them heated, but I didn't tell him it was 1.5 hours away. Lol

    drive there and your good to go. I never use tire prep unless at the track.

    Lets see some old dirt track tire recipes where baby powder, coca cola, wire wheel, razor blade(experienced only), and believe it or not armour all. Dirt is different than pavement so I still am learning on this also. I remember coca cola needs to soak in but it softens or hardens the tire....................its been like 6 years so my memory is shot on this. I'd have to call a friend. Dont try any of this lol.

    Coke is the shit for everything. Cook with it, mix rum with it, mix vodka with it, mix jager with it, mix vanilla with it... clean with it, drink it plain, prep tires with it, mix rum with it...

    Are go-kart guys the only ones who really do this? Every forum I found on it was a go-kart forum, so finding soak times and all that was very difficult. I researched for forever before I posted this b/c you said to go read. lol

    what your really wanting to know is how to scuff the tires. ive never done this since my tires are usually used when i get them but here is what hoosier says you should do. http://www.tirerack.com/images/pdf/warranty/HOOSIER.pdf the r6 and the a6 are completely different tires. your going to have to try to get alot of heat in those tires to get the optimal grip. 8 runs should do that though. if there was a softening compound i would love to find out if it works or not.

    after thinking about it you may want to get the tires on friday and when you comming to downtown go down 9 mile to senic hwy. that might do it for the first bit then go on the highway to get back. then maybe drive a little bit more to get some heat in them then let them cure.

    There is commercially available stuff, but it's very expensive.

    Yep, seen that one too.

    I'm going to throw the tires on tonight and go for a drive with them, then Tim (madforce10) and I are going to go to a spot he knows of to do some higher speed runs on them. Hoosier says to get some heat in them and then let them cure for a week before the event. The day before I'll probably do the mineral spirits/acetone/trans fluid mix on them.

    Large empty parking lot and figure 8's will work.

    When we were competing in the GRM $20xx challenges, we were using the A6's and would prep them with the above formula a week before the events.
