C8 Build
Ok so I currently drive a C7 Grand Sport Convertible. (I do not track my car) I ordered a C8 Convertible Non Z51 w/ MRC.( I still do not plan to track) This was a long hard decision for me since i tend to be a FOMO. My other choice was Z51 Package W/O MRC. ( not that i can not afford it but I set myself a budget) but i have a few questions
1) Is the rotor size noticeably different when looking at the wheel size to Rotor ratio? I do not like large Wheels with small looking Rotors. also is the calipers also smaller?
2) I read an article By Motor Trend testing a Base C8 which had 0-60 in 3.3 Seconds. That seamed a big difference I thought base was suppose to be 3.0 compared to 2.9 Z51?

The brakes are smaller on the non Z51 but then they are not really big on the Z51 compared to a GT350. 0-60 times are all over the map with some non Z cars in the high 2's just like the Z51. Too many variables to rely on comparisons like that. Get what you want.

I drove a 1LT yesterday Non-Z51 without MRC... It rode smooth even in track mode. Ordering 21 Non Z51 without MRC. i'm torn between the 1 and 2 LT. It's not the money I just would not use all of the bells and whistles.

I'm not going with the Z51.
I personally do not know if I'll be ordering MRC or not. The GM concierge had responded that NOT having the MRC would give you a softer ride. I have no plans to track so I was thinking non-Z51 and no MRC. Just the NPP for the 5hp that was probably missing on that base model they tested.

Second, 2LT versus 1LT is MUCH more than bells and whistles!
First the safety issues.
- The rear view center "TV" replacing the mirror with poor visibility is a must have if getting a Coupe.
- I would not drive a car without HUD. Too many AH on the road looking at their phone when it beeps with a foolish text message etc. I am always looking at HUD versus looking down at dash. I also have my iPhone set to not receive calls or beep when I'm moving. Understand some "can't live" without knowing who is contacting them and have to look. Some of those will just not live as long!
- Frankly with the "TV Center Mirror" set wide as I have mine, the automatic blind spot detection is really not needed but anything to help maintain my 60 year driving record of never having an accident with another car! Takes a lot of attention, knowing where all cars are around you all the time (including the AH barreling up on left or right who will soon be in your "blind spots") as well as LUCK!
The other reasons, like member seats help entry and exit. I have seats set as high as possible and fully back on exit as well as the steering wheel fully up. I'm the only driver so no needed for two settings. Other things are nice have but not essential but the extra speakers are a benefit.

C8
Hmm, 1st ride makes no difference with a none MRC car if in Touring or Track! Nothing to change ride, i.e. fixed shocks, springs, sway bars. In fact there are some upsides like you can drive in Track and get max Throttle Response not the slow tip-in with Touring etc. The nannies come in later as well.

He was what I consider and unsafe driver but so were many in Germany at the time. He drove as fast as the car would go when on the Autobahn! Even at night where he was far exceeding his lights. Once, when approaching a car in the right lane behind a truck that was going a "reasonable speed" NOT our over 150 mph, I asked what happens if the car pulls in our lane? He said, "Folks that do that don't last long!"
Yep, guess distracted driver's will follow Darwin's "Survival of the Fittest!"

What pushed me to the 2LT was the blind spot and the rear traffic alert. Anything to keep me safer is well worth the additional cost.

non-Z51, cast-iron disc (13.6 x 1.02 inches)
Z51, cast-iron disc (13.77 x 1.06 inches)
So not much difference in rear rotor diameters, just 0.17". I don't have high-resolution photos of front wheels to post, but Hot Rod lists non-Z51 at 12.6" and Z51 at 13.3" so there's a more noticeable difference of 0.7" there.
