The tires and wheels should fit proper for stance and fit. Cranking the suspension geometry detracts from the stance I believe you initially were looking for.
Was this sort of the look you were angling torwards?
"This handling superiority is thanks to a bunch of well-chosen components that work in concert to reach a specific goal. Beginning with the rolling stock, we find 17x8 Fikse wheels wrapped in 225-45ZR17 Yokohama tires up front and 17x9 Fikses sporting 285-40ZR17 Yokos out back. When you consider that the stock Bird came with F70 bias-plys on 14-inch rims in 1968, you can imagine how much lateral stick would be improved with these low-profile steamrollers. But Grafton was not about to stop with the wheel tire package in his quest for better cornering.
Proper spring rates are a must to provide a balance between all out stick and roadability. Grafton found that balance by removing the factory coil springs and mounting a HAL coil-over system that includes the shocks and coil springs rated at 450 lb. in a single unit up front. In the rear, a set of Landrum mono-leaf springs rated at 175 lbs. was installed. A 1-inch Herb Adams VSE front stabilizer bar with spherical ends was bolted in to reduce body roll and Competition Engineering Slide-A-Link traction bars were mounted in the rear to help put the power to the pavement. The Slide-A-Link system allows the bars to be lengthened or shortened to preload the chassis for a straight launch. HAL shocks are found in the rear as well and all are 12-way adjustable. Polyurethane bushings replace rubber at all attachment points and the chassis is tied together with owner-fabricated subframe connectors. Grafton said that he had installed a rear stabilizer bar but felt little difference in the handling, so he removed it. He also stated that the C-E traction bars add solid forward spring-eye bushings, which aid handling".
