Gerst Tubular Suspensions

So I was talking this morning with Carl Gerst, owner of GTS about my wheel/tire options. He informed me that the widest he's had anyone go as far as front tire width/size is a 285/30 on the front with room to go as much as .5 inches more. Course this depends on the rim offset but I recall this question rising up somewhere

I plan for 285/30s up front once I finish my GTS swap.
