Oh but Contrare Mofrare! Dana 60's is quite common among the die hards. The 9 is just easier for gear swaps for the ones that are undecided on their setups. That being the case that I noticed at Benson/Dunn Dragstrip last Summer. I saw that it was common that some of the Big Dogs had narrowed 60's. Alot of the 4 sec door slammers had 60's.
Also after going to Winnabow for the Flat Sand Rail drag races last Summer I noticed about 75% run narrowed D60's.
This all being pure speculation... I know the 9 has aftermarket out the ying yang but 60's are still common. My gear dude drag races and he swears by his 60.
It's all on personnal preference but I would think either would Git-er-done!
