I appreciate the advise, I'm a little unsure on them as I've ran a set on a overpowered merv and found them a tad slippery at times. I don't think it'll matter too much with this fun car, I'm not trying to hit the speed of light, just kick around having "FUN" for a few hour's once the kid's are asleep. I might have to do as you suggest and see how long it takes doing donut's till they go bang!!..that'll be fun for a few minutes.
