Charles, the older 911's are a Blast! Very rewarding when you get it right
Ok, so in Practice on my RE-11's, I only got one clean lap with no passenger, driving about 8/10ths did a 1:19.5, I feel I could have maybe shaved another .5 to 1.0 second of time off that 1:19.5, From my experience running the RE-11's and RE-71's back to back several times now, is that the RE-71's are roughly 1.5 - 2.0 seconds quicker.
