I got a chance to do a bit of rubber tire testing. I ran 50 wt oil f/r, with blue springs and an .055 bar f/r. Started with pit 24r and 20r (the new tires) with yoke m inserts. Camber links on the bulkheads, shocks stoodup in rear, 2 hole in in front out on the arm. Double one ways.
The car was good to start with. The kind of good where you're not sure where to go since it all seems ok. Tried integy C-22 orange springs, but they were too hard for this track. It may have been that there where bumps that made the car skip too much. Wound up with the purple-blue springs (hardest atlas), and that was fine. Made the car a bit better to me. I'm thinking that the blue or purple springs would be ok with a heavier, say .063 swaybar setup.
I also want to try angling the camber links downward, back on the shock tower. The roll centers may be a bit too low. The latest carpet setups in general seem to be going towards higher roll centers and light spring/oil. Control the roll with the suspension geometry, so you can gain traction with a softer setup. I may be able to get the suspension mounts milled down so I can use spacers under them to raise the roll centers at the mount, but until then the camber links will have to do.
Also tried some CS 22 takeoffs, actually was the best tire i tried. They tend to work really well on green tracks, which this was. They're not as good as the grip goes up, though. I know the Cs 27 will be the nats tire, and i'm thinking that if its characteristics are like the cs 22, a softer setup will help.
I think getting into the camber links will be a big help to getting the car really dialed in. I'm thinking there is some laptime there.

You need the Adobe Acrobat reader from www.adobe.com . You also need the Asian language font pack I think its called. Even if you have the reader, yu have to have the Asian fonts to make it display correctly.

You can uninstall your original AR and then download a new version with Japanese language option. Install it, reboot and then you can view those setup sheets from Miwahobby.

Ok, I finally got the courage to pull off my roll center mod. Basically, i removed 2mm from the top of the suspension mount. This allowed me to use a 2mm Atlas shim to raise the inner mount point.
Lately, a higher inner mount point is becoming more popular. At the US touring car champs in Milwaukee, Chris Tosolini raised all the inner points and lowered the hubs, like a lot of Schumacher guys have been trying. I got a chance to see his car run and it was awesome.
Also, for foam racing, a lot of the Losi guys seem to like the stock "high" roll center inner mounts.
From what I was told, a higher inner mount lets the car roll intially, and then the car wants to stop rolling. You can then use a softer spring since you don't have to control the chassis roll. You gain traction this way. A lower roll center wants to continue rolling all the way thru thr turn.
Anyways, I had to also remove a bit of material from the area of the mount where the pulley comes close to. I have pictures of all of this stuff.
I assume no responsibility for any screwed up parts you make.

RobK, Looks good man, I did get to see the new T this past weekend. The car looks great and smooth. I seen the front end is still sloppy like the old car. Other than that ,which is an EASY fix,it looks good. I'm still wanting to get one but don't know if I can Aford to this late into the season...
