I doubt I will get the hampsters in mine to go any faster. You feel silly, I put nearly 200 miles on that brand new NSX.
As for upgrade level I guess I would have to say that was a Heavy Upgrade, I know it sounds funny. You bought one part, but it was a Racing part so the majority of your parts would be in the heavy upgrade level. Now if you got a Sports Exhaust, a Large Single Plate Clutch and a Sports Flywheel then you could call it a light upgrade as the majority of your parts would be of the Sports type. Tires would be sports tires at all levels with racing tires generally for Semi-Racing and Racing, (Medium, Heavy and Extreme upgrade levels).
Things like Fully Adjustable Transmissions and Fully Adjustable Limited Slip Differentials I tend to only use on Medium upgrades and higher as they are pretty racing and semi-racing oriented, but a case could be made for them on a light upgrade with all other sports parts. This would be one of those grey areas.
Wow, 200 miles- you have far more patience than me (or 2.5 times more anyway, lol)
I think that may be an issue with the upgrade levels system for benchmarking purposes, actually the majority of the parts are stock which is less than sports. Due to my driving style, I need to be able to adjust the suspension to be able to drive the car correctly. The real quantifiable changes in times comes with upgrades that raise horsepower, lower weight, and quickens shifting- oh and grippiness of tires. Changing suspension and to a degree LSD only really allow you to fit the car to your style of racing, specially since most of us have run the 'extreme' level for so long. I have 'pet settings' for each drivetrain type that I am most comfortable with, it's hard to unlearn these driving tendencies.
From a statistical/scientific standpoint, you will get much better and repeatable results, if everyone can setup cars how they are used to driving them. You will get a better baseline on each driver, so you know going in around what times you should get.
In my opinion:
Exhaust, NA Tune, P&P, Eng.Bal., Disp.UP, R.Chip, Turbo, Intercooler, S.charger, Trans., Clutch, Flywheel, Driveshaft, Racing Brakes, Weight Red., and Tires have the highest impact on times and upgrade level.
To where B.controller, LSD, AYC, Suspension, VCD, and Inc. Rigidity seem to have a great impact on fitting the car to the driver's style and ability.
The perfect example is the times I posted for this round. With only a customizable suspension difference, I took only about 2.5 seconds off my best stock time; but out of the 9 laps I ran, all but the lap I spun out, were within 1.5 seconds of each other. My stock times on the other hand were all over the place within approximately 8 seconds of each other.
It could be that I am so used to those 'pet settings', that some reactions are just so ingrained to what works and what doesn't, that doesn't apply the same way with a stock car. Has anyone else noticed the same inconsistencies when driving stock? (those who are used to customizing just about every car they drive)
If so, in the interest of more consistent data, I think the Upgrade level rules could be reevaluated and tweaked. Whether or not the rules get adjusted, I will still be participating. But what do you think?¿
