I drove the Art Morrison test Camaro with IRS when it first came out and just loved it. The lower unsprung weight helped the car ride over track bumps and undulations without being as upset. I translate that into increased car stability and feel, which is what I was looking for, and I absolutely love the ride on the street, - just dial the shocks down. It's also a big improvement for street cars, which is the target market for Art Morrison, and Mary has proven it works for autocrossing, she's not that aggressive a driver on a road course but the car has felt great there. The downside is it takes some smarts to change alignment settings on it. We tend to not mess with it once we got it set well.
Prior to this I was thinking of swapping a Corvette IRS into my 67 Camaro but I was worried about how much build time it would eat up designing and fabricating it, and would it break? What needed beefing up?
When the Art Morrison IRS came out, I saw right away it is much stronger than the Corvette unit all the way through, needed no beef up, the lower links links are Johnny joints, and it has a Strange Dana 60 third member, durability was a big factor for me in selecting this IRS, plus it was already engineered.
