I tried the search, to no avail. So I will start a new thread. That being said, how many of you have upgraded(?) to the Cobra IRS? I have read the interview with Maximum Motorsports driver Dave Royce (I think that's his name) about his driving experience in the same exact car with a MM torque arm and panhard bar live axle and then the same car with a MM built Cobra IRS. I am pretty sold on the idea, but I am curious to see your opinions on the swap. How many of you have done this? What are your impressions? Tips/advice for those interested in switching?
