Mean Green arms for 4gear

Keith, if you're referring to me talking about the trac mag on the left, that would be the drivers side of the car, yes.

Hey Wazzer, not sure about flat vs. stepped shoes. As for the front tires being on the track, I guess it's a matter of how strong the p/u springs are. Most cars I think the f/tires are slightly off. If your way off track try different springs. Someplace in NTRA rules I have seen "on or close to" referring to f/tires.
Never have had anything with flat shoes. Seems being hinged higher than rail and flat, would make for a real small contact area on shoe. I know on stepped shoes the larger the contact area (wear spot), the better your cars will run.

Taz, you may need to VERY slightly open up the hole in the chassis that the arm shaft sets in. Basically, you would need to 'bevel' the inside of the hole. it may be the sleeve on the bottom of the arm shaft is causing it to bind. Also, I have noticed on some of the upper plates above the magnets there are two little 'nubs' that put pressure on the magnets to 'align' them. I have had a few chassis that if I shave off the nubs, it frees up the arms better.

Sounds like sleeve, if you hold chassis to light and look from side (I use magnifying glass) you should see some light under sleeve. If not look at inside of chassis, may have to turn in light to see it. If sleeve is putting presure on chassis floor you should be able to see a mark from it. Like it was polished, a ring aroung the arm shaft hole. I've found a small round dremel bit (finger spun) the easieswt way to remove that polished surface. Re-assemble with clip and spin arm. If still tight repeat process. Be carefull doing this only spin bit afew times at a shot. Had one arm that would keep leaving a mark when checking for fit. Cuping around shaft hole reaches edge of both brush pockets now. But it spins real goood.
