4+1
Mine are +3 and measures exactly 50".
My wheels are affset at 3+2.

if you really want to be at 50 inches you would need to super 2/3 rimms.

the first number is inches inside the second is inches outside

so
4/1 is narrowest
3/2 is middle
2/3 is widest and probably will handle like crap.

I had +2 a arms with 4-1 rims, and my front end was right at 47 or 48 inches. 2/3 rims will get u right where you want at 50 inches.

i think it greatly depends if you have zps shocks/sag/how much you weigh. I have +2 lagers and 3/2 rims and weigh 250#s on Ohlins shocks set up for 180 pound rider. my front tires rub the 50" wide thingy that they make you go through at the nationals, where I have seen others post on here with the same set up that are only 47-48" wide
