See, I was told to loosen it because it was thought that I was getting tire spin.

So I just return the tweak screws to neutral(from what I've seen here...each spring just touching the rear pod), then check the pre-load from there?

The one thing I am sure of is that the side to side balance of the car is dead on.

And heres where I really need help, lets say I do find that I have right rear tire preload as you suggest, which tweak screw should I adjust to remove that problem?

Is there a pan car setup guide out there? Anybody have a link? I'm looking for a list of what does what and what changes to make and the order. Something like the XXXmain setup guide.

Place the car on setup board. Put 1 penny on top of each front tire just behind the center of tire. Place an allen driver under the front in the center of chassis (seen by the hole in chassis at C/L). SLowly lift front of car. The first penny to fall off is the tire that is lifting first. Adjust the tweak screw (.050 allen IIRC) on the DIAGONAL rear tire (add spring tension to that side since that corner is compressing first.

Continue until both pennies hit at the same time.

This is the method shown to me from a team racer (not CRC), and it worked great for me......and I have to agree...no setup / tweak instructions makes for some troubled times if you dont have people that know these types of chassis handy. Looks like CRC rushed out the instruction book leaving a very important section missing.

Sounds good. That penny thing is a cool trick, takes the 'eye balling' out of things. I'll give these things a try and hopefully be tracking straight next time out.

Not sure what you mean? On asphalt track or a parking lot? Works great on outdoors asphalt track. Have not tried bashing on a parking lot but if it's smooth and free from cracks and jumps you should be good.

How does the one piece fit in the gen x 10? Any special modification? Do you have a part number and maybe a pic of your rear one piece?

Thanks for the info

Will consider buying the medium from tbang once I run some test runs and see how it handles first with the HD body. Thanks for the info

Ceramic balls are very hard, so the contact area between the balls and diff rings is very small.. You can wear in a groove to allow for a larger contact area, which will result in less slipage.
