Hi Ian,
You must have read my mind!!
I hope to be doing some races next year with Cheng sharing my car.
I hope to be able to look at his braking points, entry speeds and
so on to see where he makes all the time on me!!!

So far as the mic placement in the exhaust, I like the sound of it without, but not usually allowed to run like that.

Having said that, the speedfest at Brands Hatch in 2014 was an open pipes race!!

Kind rgds
Andy.
