If you have a lighter car, your setup has to be really really spot on, whereras if you have a heavier car, your setup doesn't have to be quite so perfect for it to get round (plus a heavier car seems to grip better in loose or wet conditions). This is what i've found with gaining and losing weight on the car (after trying to shed loads of weight on my cars, then going back to adding weights again)
i therefore will be running an absolute brick from now on
but the point is, with the weight loss of running LIPO, i would defo add weight to bring it up to the weight it was with NiMH (especially in 2wd)
bringing the weight limit down would be like pissing into the wind, or having sex with a diseased prostitute
