E36 M3 at Road America

1st time at Road America with my E36 M3. Driving HPDE3 (high performace drivers ed) with NASA Midwest/Great Lakes group Oct 7-9, 2011.
Car has a few minor engine mods, but very aggressive suspension upgrades (see below).
Running on 255/40/17 Dunlop Star Specs instead of the Hoosiers this weekend or I'd expect to have hit over 130mph down into corner 1 and 5.
Video shot on iPhone 4 using Harry's Lap Timer app. GPS accuracy with the iPhone isn't so hot, but data was still useful to get some general feedback. I plan to get a true GPS attachment for the iphone before next spring.
Used a Ram suction cup mount to hold the iphone Product Number: RAM-B-166-AP9U
'97 M3/4 Cosmos Black

Nope, video and overlay both from iPhone4. I've heard other using a gopro and doing the overlay, but no clue how to do that. There's a pretty good support forum for Harry's app so I'd check there

Are you using a separate video (i.e. GoPro) and then overlay the Harry's? If yes, how do you do that? Do the 2 units need to be linked somehow during the run?
