The premium SLR and standard '03 is VERY close in performance at INDY. I say this because I ran my teammates '03 and he got me by half a car (he is a better tuner than me to boot).. Will work on my '03 to see a difference if any.
They have the same power, but the '09 has the option with the weight reduction hood (5 kg) which gets the 19 inch too 1328 kg while the '03 stays at 1333 kg. Power and torque curves are the same.
