PCA SDR

I bought Mark Rondeau's old hot lap, and want to try it on my boxster. It's easy to attach to the roll bar with the top down, which is ok for autocross but not for DEs or TTs. Anybody else have a preferred top-up method?

Dave -
I made a metal bracket and bolted it to the interior trim just inside the back edge of the passenger door (it's best to put some sheet metal "nuts" on the other side of this panel, as it is made of plastic). It props the Hot Lap receiver at the rear corner of the passenger side window, just above the door level. Here's a picture (sorry it's kind of blurry):



If you have a BK roll bar extension, you could also extend a bracket forward from the two bolts which hold the roll bar extension to the bracket. (I have a couple I made and don't use anymore.)

I have also seen them tie-wrapped to the passenger windshield sun visor, which I haven't tried myself, but was told it worked. The IR beam from the hot lap transmitter is pretty wide, so as long as the sensor has some field of view out the window it should work.

Thanks Russel and Kim. Is the transmitter always on the passenger side, even at DEs?

At San Diego AXs, I think it's always been on the right side. DEs are not supposed to be timed, but sometimes someone "forgets" and puts a timing beacon up. At most TTs, there's a transmitter beacon on both sides (when the Equipment Chair puts them up). There have been a few rare cases where we didn't have access to the passenger side of the track at Start/Finish (like at Fontana, where S/F is on the banked front straight of the NASCAR oval), so it either gets put somewhere else on the track (creating a different timing line than the transponder system), or it gets put on the driver side and those without GPS loggers scramble for duct tape. One of my BK rollbar extension brackets is actually for the driver side in case the receiver needs to be moved to the other side of the car...
