I am using a lot of tunes I get off this site but I have a question. Most tunes here are with racing or sport soft tires.
If I have to use comfort tires, would that change the tune?

Also same goes for HP. If I have to bring a car to 500pp and drop HP 150, would the LSD settings change? I think they would drastically b/c less HP means
easier to get traction. But thought I'd ask!!!!

Thank You

I don't know if I would agree with that statement. Here are some tunes done on less than sport softs.

Try small changes in these areas; raise the ride hight, soften the springs, lower the camber.

If you are going to use an lsd with a low powered car stock settings should be fine.

All imo of course.
 
Let's say you have 2 kind of cars:

1- the well balanced over the 4 tires, that weight transfer don't affect so much.

2- the ones that with any direction, throttle or brakes input, will mess with the overall balance of the car.

With the number 2 , you'll need a new tune for any change of power or tires UP or DOWN. Sometimes this new tune will have to be far away from the first one to work correctly.


For the number 1 , staying in a 100PP range ,50PP UP or DOWN and with one grade of tires UP or DOWN (like if you have SM tires ,it'll be ok for SH and SS) , in this case yes ,the same tune generally work well.
Sometime, only the LSD accel must be changed to control the car better out corner or having more traction in the same situation.

I hope i was clear enough in my explanation.

Have a good day.

So definetly, if a tune is with sports soft or racing hard, and I have to use sports hard or comfort soft, the tune changes? LSD makes sense, but even the suspension changes?

Yes. With low grip you try to balance your settings for the car stay on the fast line, reducing weight transfer. Any excessive force passing over the tire's grip will result in lost of speed.

When you have a enough grip or even an excess of grip, you tune the car oriented for agressive driving allowing more weight transfer on stronger springs to absorb the huge force that will be transfered to the ground without passing over the tire's grip.
