The question I would ask about the Rowley frame is if they narrow the rearend to allow the use of 4 inch back space 17x8 inch wheels instead of the severe offset factory Corvette wheels shown? Paul Newman and several of the other guys who are making aftermarket frames for Corvettes all use 84-87 rear suspension because it is narrower than 89-96 rearends with have better geometry, brakes and availability.

The only company making a truly BOLT IN frame with complete C4 suspension that requires no modification to the original Corvette body is the Street Shop Inc out of Athens Ala. You can actually roll the original frame out from under a 63-67 Corvette and roll their mandrel bent, rectangular tubing manufactured frame that looks very similiar to an original Corvette frame with complete C4 suspension under the car and bolt it down with no body modification at all to your original body! The Street Shop uses coilovers at all 4 corners and narrows your 89-96 C4 Corvette rearend as part of a frame purchase. Rick Hendricks of Hendricks Motorsports has 2 Corvettes with this chassis.

With this chassis you can run 17x8 inch wheels with a 4 inch backspace that fit under the stock fenders/quarter panels instead of the severe offset factory Corvette Wheels needed for the frames pictured above.

Something else to consider.
