It was Geoff Brabham. He looked pretty relaxed in his M3 as the pace car (when i was spectating - appeared to be driving with one hand). Anyway I jumped in the 335i behind him and tried following his driving lines. i was using the paddle shifts as opposed to just leaving it in sports mode. shame there weren't 335 manuals there. i am pretty sure he wasn't pushing his m3, hence i was able to keep within a reasonable distance from him. i couldn't elicit any tyre squeal like i could when i took my 335 to the track a few months ago. i thought maybe they had switched the RFT's to non-RFT.
also a shame they didn't have any proceded 335's there either!
