The official Corrado SLC curb weight that VWoA registered with the EPA for model years 1992, 1993 and 1994 is 2,808 lbs.
Keep in mind that official Mfr. curb weights supplied to the EPA (defined as "vehicle full of all operating fluids - minus driver and load) include the weight of any optional equipment that represents more than a projected 33% ordering rate. I can't be sure, but it looks like the SLC's sunroof option may be the culprit here.
Presently the Corrado's weight per GCR ITS rules should weigh 2850 lb. with driver. Interestingly, if the SCCA allows addn'l 180 lbs. for a driver something's really screwy here, as in principle the SCCA min. weight should be heavier.
However as it stands the SCCA wants us to run the Corrado in ITS weighing more than it did as a street car. Gary Semerdjian in California has found this weight impossible to acheive even though he has 100 lbs of ballast, a larger battery, a spare tire, extra tubing, full dash, full door panels, full gas tank, etc....
I do not have an old GCR anymore but this info above should give you an idea of how important it is to get an SCCA official involved in the process early on. Make sure you get everything documented including the initial weight (unmodified) and weigh components as they come off while each step of the way having your SCCA regional comp chair validate the results.
Good luck and keep us posted as this classing process has been quite flawed in the past.
