So few months back I had a mishap at the track and last night when I tried to prep the car for the next track day I realised the right rear jack stand support is basically flatened. Will this be a problem now the whole car is on jack stands? (Safety wise)

 

You know what thats funny, because I had the same problem on my DB7 teg and it was on the rear right pad also. When my lifting pad bent it caused the pad to scrape the side of the rear trailing arm when the suspensing moved up and down. What I did was simply take a pair of channel lock pliers and bend the lifting pad back to the original position.

As far as saftey you shouldn't have a problem if its already on the jackstands, but be careful anyway.
