Yes I understand that but what will I notice? I need specifics e.g. Tighter turning radius, faster around the corner i.e. last corner of HSR can take at 120 normally but with LSD set you can do it at 130-40-50? or the really tight color corners in Cape Ring will I be able to keep the same radius but travel faster through it?
What am I looking for here?
I recently figured out how to observe and manipulate the LSD settings. I would say I have a firm grasp, as before I only ever used to drive race cars (thinking wrongly), that it was a lack of downforce stopping me getting road cars around the corners. Now I almost exclusively drive road cars, with my favourite being the Ford GT.
Anyway, here is a heads-up on what I have figured out so far.
Initial settings: The values for tihs work in the OPPOSITE direction to those of the aceceleration and decelleration settings. So, a lower setting will make the effects stronger, whilst a higher setting will make the effects weaker.
Acelleration settings: The lower this setting is the more your car will oversteer during acceleration. The higher the setting the more your car will understeer during acceleration.
You can observe this effect in game by watching the turning circle of your car as you accelrate out of a corner. If you find yourself going towards the outside as you exit the corner. lower this setting. If you find your car rotating too far towards the inside of the corner (ie spinning out), raise this setting.
Decelleration settings: The lower this setting is, the more your car will oversteer during deceleration. The higher the setting the more your car will understeer during deceleration.
I would also like to clear something up. these settings do not just work when you are braking, they work ANYTIME you are not accelerating. So for example, if you are coming towards a fast corner, you can ease off the accelerator, and you will notice these effects taking place.
Have you noticed when you ease off the accelerator (during cornering), that your car will turn in more than it was during acceleration? Well this setting alters how strong that turning effect is. The lower the setting the more the car will turn-in, the higher the setting, the less it will turn. You could equate this setting to the turn-in angle as you enter the corner.
It was this setting for me that solved the mystery of not being able to get road cars around corners. Now I have figured it out, I happily race road cars anywhere and everywhere!
Other notes
It is worth pointing out that it is generally a good idea to have your acceleration settings higher than your decelleration settings. This isn't a concrete rule though as differect cars require different settings, and you have to find some settings that fit your driving style.
Also, there is a correlation between the deceleration settings and the acceleration settings, because if you have your decelleration settings too low, you can find your car spinning out during acceleration, due to the angle at which your car was in to start with. Find the balance between both settings, instead of trying to compensate for the weaknessies in one settings, by drastically alter the settings of the other. I hope thiis helps. 👍
I apologise for my crappy spelling. The PS3 does not have a spell checcer!
