Yes .......or larger wheels allow longer steering arms.......
That's why when designing a suspension you always start with the wheel size first.......
Or in the planning stage the verticle tubes are moved back the amount to get the 10*degrees from the rack to the steering arm.....
Moving the rack up an down will affect the bump steer ......
So a GT car set up with 5*- 7* degrees of castor (now you need power steering) and -3* degrees neg camber and 1/8th" tow in and 10* degrees of Ackerman will go straight as a arrow at 185 mph and go around a corner provided it has been bump steered to .015" inch in 4 inches of travel.......
Hope I didn't get to far off track........my brain is much faster then my fingers.
