<<The complete package lends itself very nicely to carving the roads. I
don't know about on the track, because I've never taken the car out on a
track, but it's definitely fun to drive. I recommend the eibach/bilstein

breaking.  You could clearly see the car with and without Delrin, the
non-delrin cars front tires would dive back about 1" in the fenderwell under
breaking, delrin equipped cars had no noticeable movement.  They are a
definite must for the track.
