Thank you, this is on asphalt I presume? Which compound also?
No, it was on carpet. They were hard fronts and soft rears. I can't give any info on which inserts were used. Did a handful of laps with them on asphalt, but decided at that time the inserts in the front tires were wrong. I gave the 55mm Shimizus I owned to another racer so can't check exactly.
My overall impression of these tires is favorable, but since all of my racing in the future will be on 60D tires, saw no need to keep them. Too much work to figure out the right wheels and inserts and find the right set up for these tires.
