I'm surprised no one's linked to that BRM Type 15 MKII supercharged 1496cc 135º V-16 mp3 as they are so wont. The mic is in the pits and you can hear the car the whole way around the track.
I'd prefer the current exhausts were just made smaller, rounder (oval pipes??); generally less obnoxious. I recall the peasants revolting when the current look was introduced.
If you look under the car it's a little bit more than tips we're talking about.
Buy S2... I don't see what good waiting will do you, unless you're planning on not buying it if it isn't much different from the current version. Hell, a lot of people seem to think it's worth it as is.
A lot of people would also rather that the devs spent more time on new cars to fix the phenomenon you're complaining of instead of some feature which would only be welcomed by a minority.
Any opinion on what gives better performance is style.
Brakes: Some people use less engine braking and thus a differing brake balance; some people like to be able to floor it whenever they want to without locking up, while others prefer the ability to get closer to the limit at any given time.
G/R: () Some people choose not to use all 5 or 6 gears on a given track; some people choose to have a very tall first gear so that the rest of them can be closer.
Suspension: As mentioned, the most obvious is how over/understeery one prefers the setup; some people are driftier on the rally courses; some prefer to go the full race distance without any damage to the suspension or front spoiler, so they will drive with a taller ride height.
Downforce: Some people are braver than others; also balance.
Traction Control: Again, some are braver.
Differentials: Some expect different things from their differential; some are braver in this regard as well.
Tires: Some may prefer to baby a set of softer tires rather than rely on harder rubber.
Steering: Some people would never use full lock, and others would use more if they could--especially in rally courses where one might get his tail a little too loose.
You probably have a different driving style from your grandmother. The generic "grandmother" would probably opt for a set which differed from yours.
