Is IRS really THAT superior? I think it depends on the track and the way the car is setup. I DON'T think you can make a blanket statement and assume that IRS is "always" better than a live axle.
Couple of examples: Ed "DV" with his Classic Roadster and live axle could pull OVER 1 G force in cornering. That was with STREET TIRES no less!
NASCAR runs a live axle and weighs 3500 pounds. You THINK they handle pretty good? Stick like glue!
The FFR mentioned above was clearly NOT setup correctly. EVEN with a live axle, "drum brakes" and simple "basic" coil over front suspension the FFR's can be QUITE REMARKABLE in the handling department. Why? There one of the lightest replicas out there, and weight is a HUGE factor when it comes to handling!
Road race against equally prepared FFR vs RX-7? I wouldn't be so quick to bet on the RX-7.
How many of todays "stock" cars can corner over 1 G from the factory? You will only need ONE hand to count them!
Rough surface track? IRS will have an advantage. Smooth track? Maybe not! Which car cost more? IRS hands down.
Having said all that, sure I want IRS too. Willing to pay the "extra" for it? Maybe not. BDR is a impressive car for the money though!
