Randy Pobst has uploaded his track comparison of a 6th gen SS 1LE vs the S550 Mach 1 with the Handling Pack. The SS 1LE was on what appeared to be C7 ZR1 wheels (likely aftermarket replicas) with the same model and width tires as the stock Mach 1 HP.
Key Points:
-Mach 1 was a 10-speed auto, SS 1LE was a 6-speed manual
-Mach 1 was 0.4 seconds faster around Atlanta Motorsports Park
-SS 1LE felt wrong to Randy, brake fade and mid-corner oversteer he claims were not present in SS 1LEs he's driven previously
My takeaway is that IF there truly was some issue with the brakes and alignment like Randy claims, the SS 1LE would probably have won without those issues present. However, the Mach 1 won that day. Maybe next time the tables will turn, just gotta bring a properly setup stock SS 1LE to the party.
All that aside, the Mach 1 HP is still $12,650 more than a 1SS 1LE with a 6-speed. Is 0.4 seconds per lap worth $12,650?
