Where do I start? Received my 2015 Z51 M7, white with black interior 1LT September of 2014. First thing I did was remove the front license plate shoe box. Such an ugly piece of plastic. I tied the front plate with zip ties to the grill .... bent the plate slightly to follow the contours.
So here's the list; ARH mid length headers with high flow cats, Halltech carbon CAI, Granetteli insulated spark plug wires low impedance, trunnion upgrade, Innovator West light weight balancer, Z06 front grill, ACS front spoiler, rear diffuser fins and side rockers, 2LT drivers side sun visor with home link, flat bottom steering wheel with carbon insert, carbon plenum and top fuel rail covers ( the plenum cover is for sale) MSD intake manifold, Weathertech front and rear cargo mats, Braille light weight battery, Borla catless x-pipe, B & B Bullet exhaust with speedway coated black tips, LG G2 coilovers, LG quiet end links, Katech light weight flywheel, removed rear cargo carpet (also for sale) removed and deleted NPP and AFM actuators, tuned to remove 1-4 skip shift and 4 cylinder mode, Sunteck window tint, Carbotech 1521 brake pads, Dynamat sound insulation, Edgyvette resistors so no cel with AFM actuator removal, LED trunk and rear license plate lights, debadged the car, MGW shifter, DSS carbon driveshaft, silicone rad hoses, 180 LMR stat and billet housing, replaced black center wheel caps, pulled fuse #42 for the NPP.
The biggest difference in performance were the headers and cai.
The biggest difference in ride were the coilovers.
The biggest difference in shifting was the flywheel.
Overall, the car dropped about 100 lbs and gained, hopefully when dyno'd this week, about 100 hp.
Next come brakes and tires once the oem ones wear out. That should drop another 30 lbs.
Most of the work done by Dave and Nigel at Race Ready. Thanks guys.
 
How much weight do you think you saved going to a carbon fiber drive shaft?
Difference between the OEM aluminium and the carbon approximation 7 - 8 lbs
But also a noticeable difference in the shifting more crisp less notchy. This is also rotational inertia which makes quite a difference in translating hp from the engine to the rear wheels

Those are some fantastic mods, but where are the pictures? :p 100 pounds is pretty impressive!
I’ll try to upload some pics
