The problem with Lime Rock, even in a stable, relatively easy to drive car like the MX5, is that in order to obtain sub 1:00 minute lap times, you have to really take risks and keep your foot in it and there's NO margin for error. Best case scenario, if you really push it, having an incident free race without an occasional dropped tire is tough. And as you gain levels, your SR can suffer, even without making contact with other cars. Worst case scenario, you push and push and push and then from just a small mistake, you really stuff it and end up off the road and into the tire barrier or worse. Then your SR and iRating suffer.
I like the track but I have to admit, guys who can maintain consistent lap times of 1:01 or less, even during the last 4~5 laps as the tires begin to lose their bite are very impressive and they have my respect. 👍
