Guys....Noobie....Here whats the difference between uptravel and droop? and how is it I read about guys setting there droop above ride height? does that mean if my ride hieght is 5 my droop is 6.5 if my droop is 1.5....Does that mean I use droop blocks and set my arm at hub on my droop guage and it should be at the 6.5 mark? I am alittle confused......What is a good amount of droop? Also if my car is loose or lifting a tire in fast corners can droop fix this? any help is appericiated.....By the way I have a setup book on order...

I've never heard the phrase 'uptravel' used, only droop and downstops.
As mentioned droop does not effect ride height, but ride height will effect droop.

I haven't tried it myself I believe people have noted that the EU chassis and the US chassis are slightly different in that the motor mount position is further forward on the US chassis than on the EU chassis... ?
This would mean that trying to mix and match chassis and upper decks will be difficult...

If it is the 009 they are the both interchangeable.

EU rear traction issues
Having problems with rear traction (rubber tire on carpet). Springs, roll centers, sway bars, damping all seem to make only a moderate difference in rear grip. My 009 is certainly lose in the rear compared to my 008 with identicl setups and they're nearly the same except battery position. I know I'm not the only one struggling with this so ....whats everyone doing to gain rear traction?

You could also try making the rear link as long as possible, lengthen the wheelbase and even run 1 degree rear hubs and put the rest of your tow in with the shims. Also running the -.75 wheel hexes(in the rear) will make the car norrower in the rear gaining grip as well. Play with acerman too, this can be a big change sometimes. disconnect the rear bar ect., all of these help make the car more stable in the rear.
Hope I helped that was a lot haha!

Last night at our club race I; - lengthened and raised the rear outer link, reduced rear sway bar size in 3 steps, reduced rear droop by .4, increased and then decreased ackerman by 2 clicks, reduced rear springs to 2.4 and then layed shocks down 1 hole, decreased rear damping, increased front damping (not all at once of course), really got nowhere....so I went back to my original setup with NO rear sway bar and the car was acceptable.
Lowering the rear roll center made the car feel lazy as did reducing the rear bar. Ackerman seems to change the way steering is applied but does'nt change the amount of steering. I didn't try reducing the rear track width or increasing the front... good point, I'll try it.
I'd also like to be able to introduce more chassis flex, maybe the asphalt upper deck?

I feel your pain Jim. I have 2 days of testing scheduled this weekend just to work on this. If I find something I'll let you know.

What is your set-up on the front of the car? What tire? What body? Is the car loose on entry/exit? Here is a link to my set-up updated as of Wednesday.
