I wonder if some of you that have experienced "rubbing" are running slightly oversized tires as compared to others that are not rubbing?

Are all of you running the type same springs and shocks, and are the shocks adjustable?

...just wondering if there is an apples to apples comparison here between the BDR cars...

If not, I've found that rear adjustable shocks are fairly necessary on Cobras, especially well-powered Cobras that squat really hard under power coming out of turns or under hard acceleration. Adjustability here makes it nice so you can set the suspension based on your (preference) need and condition..... soft for those cruising days, or firm for those more agressive roads or events. I run a different car, but this principle is the same.
