They have been quite the topic of debate and just recently ruled illegal for Cleveland this year. Check out the Jaco tire news thread for more details, I am sure Jack would be happy to answer any questions you might have.
two stage tires were used at the last Snow Bird and Cleveland....and maybe races farther back?
now that they are available to the public...conflict? nobody had any beef when only the sponsored drivers had them. 2-stage/wraps were no secret and were discussed pages (i do mean pages) back in this forum. pics were posted after a race last year and some mentions were from sponsored drivers this year. it was found out months back, Jaco wasn't the only one making them.
how can anyone be sure that no one hasn't taken: Yokomo, Parma, TRC, BSR, BRM, CRC, Corally etc. rims and had someone special make them a set of 2-stage/wrap mounts? maybe for their own drivers? maybe for only one race...such as the Worlds? Maybe issued before a race and returned after, so there is no slip like last year where someone mentioned the 2-stage/wrap and threw it away at the end of the race only to have someone retrieve it and get the word out. now we can buy them and they are a issue with the rule makers or race promoters.
how are they going to tech for this? didn't before? cut tires at the end of mains?
i like CRC new 38 Procuts, very nice...but wait, what about a rim this size done up as a 2-stage.............
the last three years, i would say anyway, 12th scale has had a rebirth of some sort. look at all the different conversion kits alone that have been released. anything to make the cars faster and handle better shouldn't be outlawed. phase it in, like they did batteries and BL motors. well...maybe not the way they legalized BL motors.
ah and batteries...are the guys in Cleveland and any other races ROAR or Non-ROAR going to tech for batteries such as maybe GP3900's in 3700 wrap?
measure cells? weigh cells/packs at random? there were some issues i remember awhile back on a forum about accusations (sedan class) at a big race where some team drivers were rumored to had 3700's in 3300 wraps. this was before they were available in the US. yet amazingly no one protested. a scale and calibers would have revealed the truth....but no one wanted to go there i guess?
this was done many years ago when 1200/1300's were the only game and 1700's came out. the reason this was done because 1700's were found with 1200 wraps on them (uncut on the sides). 1200's had a K stamp or no stamp on the neg-end. the 1700's had a KW on the neg-end. some polished out the W and soldered them to barely show the K. but the scales and calipers told no lies.
