Oh and just another thought. My TT had pretty heavy weight transfer too. Changing the watery shock fluid out for AE FT 50w shock oil cured many of the handling woes for me. I put the 50w in at all 4 corners. As I ran the truggy more and more, I noticed I was having to keep adding preload shims as the springs got gradually softer with use. I was researching heavier springs with lots of difficulty as HPI didn't make any other rates in the same size for the TT. I then starting thinking about just stepping it up a notch and find some big bores that had easy to come by variety of springs. After learning that I would be spending $100+ to go to decent big bores, I figured that's more than a 3rd of a new D8T....so then I ordered a D8T and have put my TT on the back burner. I think it will become an on road nitro car this winter while I'm stuck inside waiting for warm weather.
