My only experience with spools has been in karts, but considering the lack power they had and the grip levels they were generating they certainly were very lively in the corners. I'd think it would be a lot of fun in a track car, but I personally will be saving for an LSD.
Off topic I know, but didn't the Miata have slightly more power and less weight than the AE86? And as a NA Miata owner, I don't think either of those cars have real traction issues beyond first gear, haha.
