Does it have kind of a "pushy loose" feeling like the front end slides to a point and then the rear whips around?
yes that is exactly it, what can i do about that?

Thanks. I'll see how I like it this weekend.

Usually if a car is pushy loose, it's not a problem with the setup. It's a problem with overall traction. The car won't be "in" the track and won't feel like it's gripping anything. The first thing I'd normally look at is tires. What tire/wheel/insert are you using? Are you running the same tire/wheel/insert combo that everyone else is running at that track? What are you using for tire sauce if any?

Also, if your track is just very low grip and your tire and tire prep is the same as others not having this issue, I'd suggesting just trying to soften the car up as much as you can. Add droop all around, take off swaybars, softer springs, etc... Low grip tracks will usually need a car that transfers weight.

Very possible. Before you go changing the whole car around, I'd check to see what tires other people are running. I've made tire changes testing things and took a decent race car with one set of tires and literally did 4 wheel burnouts and slides with a different tire. Some tires just don't grip on some surfaces. Others grip too much. We couldn't run RP tires at SoCal (high grip indoor asphalt) because we kept traction rolling. So we ran tires like Sorex 32's and 36's.

Yeah, just so we know exactly where your car is so we can go from there. 1mm on a vertical camber link location can be quote a bit. Make that change, find out what tires are being run. If the tires are different, try the car like it is with those tires and go from there. If the tires you ran are what everyone is running (tire prep as well, i.e. sauce, warmers, etc...) then you need to look at what to do to the car.

What always seems to work for me is a little anti-dive. I put in .5mm at the RROC and loved it.

Anybody have a part number for the Schumacher diff grease aka the "best diff grease on the market"(as quoted by AdrianM)

I just finished rebuilding my diff because it wasn't as smooth as I wanted when I first built it, plus I rebuilt my Tamiya diffs using the Schumacher grease, so now I'm out and need some more. But I couldn't find the part#.

Thanks in advance.

I think it is U1301, maybe Adrian or PW can let you know for sure.

I notice you've had a lot of other answers about the various problems, with regard to the rear diff, tighter usually means more less steering on turn in and oversteer mid corner to corner exit.

A question on camber links,

I currently have 3mm vertical on the front and 2mm on the rear (Mi3). If I was to try to get more rear grip on a fairly smooth track, would adding even more to the rear help or make things worse?

I'm always unsure about when to try changing the length of the camber links as this wasn't an issue with the EC.

Thanks
Skiddins
