Wow... do you by any chance have any contact details for the owner or shop that did the work? Would be much appreciated - that is an ideal set up for me.

If you want to stay with Ferodo pads, find a compound that matches up with the Hawk DTC60 heat range. You might find Raybestos in same heat range also.
Gotcha - was thinking to keep the DS2500s as my street pad just in case I run out of pads while at the track. Will switch over to a track pad. Don't care about brands, but the DS2500 seems fairly unique in that it is a trackable street pad. Will probably try DS1.11 Ferodos as the track pad.

I ordered one to try it out, but having been cinched up in dedicated race cars, I have a feeling I will lean toward the full harness / seat set up.

If I can track down some info on the rollbar that allows use of the soft top and the price is reasonable I'd be quite happy =)
