I run the Hotbits on the 2002 SVT - super pleased with them. We get all our gear from Peter Reilly (2003 Canadian Rally Champion)

We did a complete rebuild about 3 events ago. Peter sent all the parts, bits, instructions, settings, recommendations, decals :) - flawless - those guys are absolutely spot on when it comes to customer service.
At IRNY 2011 we did crush a rear resevoir line, but a zip tie failed holding it, NOT the line - like the rear left SAG....LOL
Just got the parts from Peter to convert the rears from a STRUT/SPRING setup to Coilovers - super excited to run them.
Have a track day in APril at NHMS in prep for Rally New York Tarmac - and am actually going to play around with a firmer setting, lower perches, sway bars on. If that is not ideal - will swap in the tarmac springs - but even on a tarmac rally - will be bumpier than a proper track.
Simon - if you are following this thread -what are you going to run for New York?
