No I mean a 30 degree offset triple. I have never used a longer swingarm. I used others and found them not to be as effective as the 30. Above you had mentioned the raising the front by pushing the forks down. Whenever you raise the CG it makes it effectively top heavy which makes the bike and I hate the word flickable. But never have I raised the front and left the rear alone. I have raised them relative to each other.
The fork offset dimension is measured in mm, not degrees.
Also, reread my post where I say:
"The front and rear ride heights should be increased equal amounts."
