Exactly what Greg said. I drove a FWD ITB car for years, could do heal-toe just fine (always did it on my street car cause I thought it was going to be necessary), but never found a gain by doing it. Instead, I found that one time I'm under pressure, it's one more element that I could potentially f-up.

My ITA Miata... What Greg said again. Tried without...Ugh.

It's not a bad thing to learn how to do on your street car. I'm all for learning different tools you might someday want to try.
