the spoiler rule is what it is BUT if the used tire inventory dries up to fast it could hurt the class---I for one cant afford to buy 6 tires at the start of the season--I would hope ump will allow the tires us lower $$$ racers have to be used up at a slower pace JMO
And IMCA isn't on the same tire. From what I understand about the new ump tire rule is they are removing the A and going to a compound between the A and D...the same compound as a late model LM30. Won't this allow more grip and basically cancel out the spoiler change?
Honestly, I don't think any of this is going to change anything.
I guess it really depends on the weight break if any and what tire they choose to allow. I think with a hard tire and taller spoiler for crate motors it could be a good thing.

IMCA went from a 3" (2013) to a 2" (2014) spoiler.
But the IMCA "open" motor compares to a 604 a lot better than a UMP open motor compares to a 604.
Will UMP give the 604 the 100# weight break still?
UMP should go with the G-60 tire
