I've noticed over time that the rumble strips seem to have more grip. It's like you can take turns at a higher speeds if you have the two inside tyres on the strips, but if you come off the strip, LOOK OUT WALL, HERE I COME!

Can anyone confirm this?
 
That's probably because the rumble strips are near the Apex of the Turn. If you hit the Apex and hit drive on the Rumble strips, it is he most efficient way of hitting the corner, thus producing a better racing line. Doing this makes your trip through the corner more like a straight line, and the ultimate goal of race car drivers is to drive in as close of a straight line as possible.
 
Actually, :D

The rumble strips do help turning.

In real life, I'm not too sure... I think in real life the rumbles provide less grip than tarmac.

However, in game...

In the game it is different.
For some reason the designers of the game made it so that running along the rumble strips makes it possible to take turns without understeer.

That is really what it is about.
Understeer.

Without the understeer provided by an extended tarmac turn it seems the car can defy the grip limitations and oversteer through incredibly long turns.

If you don't believe this go race at Apricot hill forward or reverse.

Also, to get the testiment of dozens of racers, go to the weekly race series archive and search for apricot hill and long turn.
I am sure you will get tons of post supporting the fact that riding the rumbles can yeild better lap times.

Why?
I don't know, the above was just my initial answers to the question, but with a topic like this I am sure more replies are coming.

Till I get back to this thread,
Later. :D
 
Hear Hear! GoKents!

'tis true. Think it has something to do with having 2 wheels on a raised, adverse-camber surface and 2 on regular tarmac that allows the car to turn quicker. Although, my physics background knowledge suggests otherwise. Maybe we should consult someone with a physics degree. I know Newton figures in here somewhere, but right now I'm too drunkeley to care!!! I'm a chemist, and I know this.... excessive Ethanol intake = excessive Bul&^%it output!!! :crazy:
 
But surely providing less grip on the kerbs would help you turn? The inside wheels are on the kerb, outside wheels on the tarmac. Outside wheels have more grip and are pushing the car round the corner better than the inside ones. So the car turns better when the inside wheels are on the kerb.

Probably.
 
Let's not forget that when it comes to the Elise and Motorsport Elise, rumblestrips can often be a big "no-no" ;)

Seriously though, many times the rumble strips do lead to an improved turning line. Whether it is a grip issue or an induced camber issue is difficult to debate. As good as the GT3 physics are, they are still off from real world physics in quite a few ways. The phenomenon we experience with rumble strips may just be a combination of factors within the emulated physics that produce desirable effects.
 
It's mostly a grip issue. Raising the inside wheels won't help you, because it raises the CG of the car. However, the other thing operating is the impact of the inside wheels as they get up on the rumble/curb. This slows that side of the car down, which pulls it into the turn more.

Just like in the game, riding the rumbles in real life varies by car and track. There are spots where they help and spots where they are poison.
 
I used to think that, but over months of playing the game, I don't really think so. At any rate, they don't wear your tires nearly as much as skidding does.
 
Rumble strips all depend on the track on whether they will help or hurt lap times. A fine example of using the kerbs to achieve a faster lap time is Formula 1 at Imola. At Imola, the cars have to use the kerbs to obtain the fastest possible laps. In fact, watch just about any Formula 1 event and you will see the drivers consistently using the kerbs to their advantage; when of course driving over the kerbs is deemed advantageous.
 
In real life rumble strips can give you an advantage, but as stated above it does depend on the track and the car.

However in the wet rumble strips are a big no-no, the painted surface becomes like ice and you lose all traction.

Unfortunately I know this from practical experience at a wet track day. Very, very embarrassing to end up facing the wrong way because of a wet rumble strip and boy is the loss of traction rapid.

Back to GT3, this is not represented on the two wet tracks where you can use the wet rumble strips with no noticeable problem.
