The differences are this (compared to ZL1 coupe):

Body
-Black-wrapped hood and blacked-out mirrors
-Slightly larger front spoiler
-Front fascia-mounted wheel/tire aero diverters
-Pratt-Miller/GM designed rear wing

Suspension
-Multimatic DSSV dampers
-Front radius arm is a different P/N (different bushing design)
-Rear knuckle/upright is a different P/N (higher durometer bushings)
-Rear cradle has solid metal bushings (in place of rubber)

Wheels/Tires
-305/325 (F/R) GY Supercar 3R tires (near R-compound tires)
-19x11/19x12 (F/R) wheels

Miscellaneous
-Revised calibrations for the track and to accommodate component aero/suspension and tires changes


My suggestion is to start with wheels and tires, the solid-metal rear cradle bushings, fill up on your fluids of choice and brake pads of choice and go at it. Maybe add the aero.
