A little loose on entry isn't a bad thing, just look at Moto-x and GP bikes...Ken Block is loose on entry
If I could make a suggestion...now keep in mind I'm only a partial expert and not in the field of suspension or driving....or mustangs. Not so good with women or finances either, come to think of it I've really got no business giving any kind of advice. I did however attend one of Ron Suttons classes so that qualifies me as someone who has interest in the subject.
Here it is.
1) lower rear .5 psi
2) more cowbell
Good to see you're out having fun and making improvements.
