A neuspeed race set-up will drop your front about 2.25 inches and the rear will be around 2.0 inches. The car will set in (or get a little lower) in about a week. The front tires should be tucked in and the rear should be very close to tucking under. As far as the bumpstops..... im not sure. I think it has something to due with performance so it would be wise to cut them like neuspeed suggests. Hope this helps.
