I was using 1XA/1E in the rear with 13.5/rubber/carpet forever. The car REALLY came alive when I went to 1XA/1D, but it was a little edgy and easier to break loose. That's definitely what I'm going to base my setup around, though. 1D/1D up front is so much easier to drive. 1C/1C was really twitchy with a spool.

I can't be in the sun too long so I've been racing on the carpet.
Grip is pretty high there so ... less rear toe in.
As for the front end , sweeping the arms back makes the car turn in harder. Mostly used on pavement but could be a bit twitchy on carpet. I wouldn't sweep the front arms forward for any reason.

Two things to remember if your going to try front arm sweep forward or back is first it will change your wheel base and secondly will slightly change the feel of the suspension harder or softer. I believe this happens because of the change of the lower shock mount, sweep back makes the shock mount longer, sweep forward shortens the shock mount. A lower mount change is a far more course change in comparison to a upper shock mount change.

I believe thats because it changes the shock position angle which in turn is like moving the top in more, or like splitting a shock spring weight. Once you do a arm sweep and move the upper shock in all the way, its time to go to a harder spring and start at a neutral setting agian till you get you prefered feel for the track.

It will also effect Ackerman.

This could be a product of trying to build more mechanical grip into the car, which works right up to the point of maximum grip for the tires, past that and it starts to work against you. You could actually get the tire too warm to grip. Don't get fooled into softer is better on suspension, try a next step up harder spring, sometimes it can make a hugh difference in grip, to the good.
