[Grey 65]

Car is fine being jacked as shown in the photo. Avg BDR will weigh in at about 2,650lbs wet with a 57% rear weight bias. Those outer bars are more than capable of supporting 700lbs at each point.

This being said when I jack car up at home I use inner rails at 4 jacking points. When I jack a side of the car up at the track I use outer rail 1 jacking point.

In conclusion, I have probably jacked my BDR up using 1 jacking point on outer rail than you will ever do using double the jacking points... i.e. it is fine to use outer rails.
