    SETUP NOTES: After 20 minutes of painstakingly adjusting my axle/tire height, when thumbing my front tires with the car on its back, I discovered them rubbing the oddly shaped light buckets. Carefully grinding down all the various bumps from the bucket will be Permitted to resolve the contact; as well as adding a thin washer to the body post; or other innovative ideas. NO, truing the tires some more did not completely remove the contact; and I am running the stock size NSR-ZeroGrips. Note: I did Not have this contact issue with my C6R in 2016.

    WEIGHT TUNING NOTES: My C7R Wheelbase is 85mm (axle to axle). Centerline is 42.5mm, appx 2mm forward of the Drop-Arm pivot  (The Centerline is placed over the middle of the gap between the scales)

    My C7R Vette weighs 75gm; the textbook weight distribution is between:
    Front 40% / 30gm       Rear: 60% / 45gm
    Front 45% / 33.75gm  Rear: 55% / 41.25gm

    As stock, my car’s distribution was:
    Front 36% / 27gm        Rear: 64% / 48gm

    Adding 5gm to the nose of the pod[1]: car=80gm
    Front 40% / 32gm        Rear: 60% / 48gm

    NOTES: Each model will have different centerlines; each car will have unique weights. Depending on the location the weight is added, will affect the front/rear balance[1]; weights on the Pan “wings” may be easier to tune than a single weight on the motor pod.

    At 4-years old in Pensacola I repaired my steering linkage on my Ford Pedal-car. Dad later converted this car to a Blue Angel with ailerons and elevators with a working "stick/yoke"; the rudder was controlled by the steering wheel. I like all motorsports - I grew up going to a NASCAR Feeder track with Sportsman and Modified classes, and was lucky to attend drag races in 1970 at Orange County Raceway. My first solder-iron was a Christmas gift at 9yo; I modified T-Jets to be AFX spec before AFX Cars were in local stores. I rebuilt a few tractor & car (SIMCA) engines plus transmissions by 15yo (I still have my ring-compressor and valve spring tool) I am a former mountain and road bike geek & perennial sound engineer.
