We built our 944 (late last year) to last years weight. We did a Driver's school in February, and have raced twice since then... so it's been tough to take the car apart and do an "all-out effort" on the 140 lb. weight removal. However, between each race we strive to remove more weight where we can. We've been scraping undercoating and removing some things that we probably should have removed when we built the car. Most of the weight that comes off easy at this point isn't in the right place. Currently we would need to add ballast if we had a 180lb. driver- which we don't (more like 225lbs).
