A very disappointing 154mph in the 996 C4 this time (so presumably an extra 30degrees of heat, a girlfriend and a bunch of camping gear on board doesnt help then! Even with the back seats down...)
I had lots of 180's and then 182 on last run. 996tt X50! The new diverter valves helped as the aero kit has always made the speed about 3 mph less than Daz's
