I use a 1/2" for caliper work, and darn near everything else... Ironic that one car that gets this wrench is my 94 Camry, and I have no problem with clearance doing brake work. Gonna need the 1/2's higher weight range for lug nuts, and 150 lb lbs is just shy of what is spec'd for front strut-to-knuckle bolts, control arm bolts, etc.
If you can find an accurate wrench that goes from 20-250 ft/lbs, that is really nice as it covers CV axle nuts, rear strut bolts, etc. Can't speak of this wrenches quality, but if accurate it would be a nice choice:
