Road and Track had a comparison of cars in "Sibling Rivalry" a few years back.. they had a Camaro SS, Z06, S2000, NSX etc..

figures for the Camaro SS
325 hp/345 ft lbs torque
0-60 5.5 sec
60-0 129 ft
Lap time (around Thunderhill) 2 min 16.46 sec
slalom 60.0 mph
skidpad .87g

S2000
240 hp/153 ft lbs torque
0-60 4.9(actually time for the NSX, but it's what's posted for the S2000)
60-0 134 ft
Lap Time 2 min 17.66 sec
slalom 65.9 mph
skidpad .90 g


The Camaro SS is the same vehicle as the WS6 TA, same power etc..

you do the math..
