Its like the MC07 verse the MC08. They both are strong and look good. The MC08 looks better and is stronger but the MC07 is stronger then a stock t-case housing and is made of smiliar materal. Same goes for the Billet and forged arms, Both are super strong. The billet has a smoth finish the forged has a finish like the stock steering arm. We going for a standard kit with the forged and a higher end kit with the billet, just like with the MC08 and MC07. It gives the customer more choices.
