Is 9-10" front wheels possible with stock sub?
 

I was reading details of DSEs superb new front subframe and notice it takes 18" x 10" wheels! So there is possible to use 285x18 " fronts? What is the widest front wheel wich can be used with stock 1969 camaro subframe ,if equipped with DSE A-arm,coilovers and unisteer r&p ?

Control arms, and r&p don't help in the effort of using a wider wheel with a stock subframe. The frame itself is the limiting factor.

CarlC is running a 9.5, under his '68. But the turning radius is reduced, you must use short steering arms, and the tires will hit the frame at full lock.

DS&E subframe is a whole different animal.
