Again, I’m writing while having my first coffee, posting this without first reading though it and now heading off to get that other much needed second cup. … :)

“That’s what I’m saying though; if you’re using all the grip available, regardless of which tire you’re leaning on the most, you physically cannot corner any faster. After that it’s just distributing the grip through the tires in the proper order to achieve the desired apex and exit speed.”

Thank you.  I think you sparked something which is taking others towards what I’m still trying to point out.  It’s about there is something between deceleration and acceleration.  All drivers to be fast must learn special skills to deal with what I like to call the transition from deceleration to acceleration.  I mostly watch LTO(left turn only) and it originally and reciently within a few years of today showed itself to me LTO racing.  It’s something I’ve been watching forever, but never saw it.  When recognized it instantly took a lot of the mystery of why some are just faster then others.  I understand heart and put your all into it.  I assume and think all racers out on the track are doing just that.  I also believe any racer out on the track who is not and who’s sole purpose out there is to win no matter what their chances of winning, has no business on the track.  But that’s for another thread and moving towards the discussion would just be hijacking this thread.

Back to the discussion.  There is something between ‘Threshold Braking” and “Trail Braking”.  How much is there in-between is no different then before and after.  How much opportunity is there depends on circumstances and what the track at that point has to offer.  In LTO racing since it shows itself with a brighter brush, it is often referred to as rolling the corner.  Depending on track conditions, available hp, racing needs, etc., it may me momentary or it may appear to extend through most of the corner.  I think I am the first person to try to define it specifically and to present a reason why it can occur, even at a higher speed then entry.  I think were talking about something you have never read about before this thread.

To further understand what I reluctantly will call rolling the corner and discussions coming from it about different ways you can roll a corner, Ray brought up ‘rotation’ and I think we need to understand rotation.  I have come to define in my mind ‘rotation’ in two ways.  You can rotate through a corner, meaning to go through a corner on a curved line.  What your racing also has the ability to cause itself to interact with the track via it’s tires, in addition to traveling on a curved line along the track.  It can also make effort to rotate the outside toward the front and inside toward the rear or nose toward the inside and rear toward the outside.  The end result will be the whole kart rotating through the turn in a specific direction, because of its efforts to rotate as I described in the previous sentence.

That means when I speak of the ability of a kart to rotate, I’m speaking of it’s ability via the tires to cause it to want to twist towards the inside while negotiating the turn.  What your doing when you setup a kart and while driving is to make individual tires. combined to work toward a goal where kart rotation causes the kart to be able to go where you want it to go.  It is complicated.  There are different way to use your tires to get the same amount of rotation needed, to travel in the direction you want to go.  It becomes even more complicated because there are different ways to use your tires to brake and accelerate in the direction you want to go.  Understanding setup and driving is understanding the different ways you can use your tires to brake and accelerate in the direction you want to go.  That is pretty much all that is dealt with in all the books you will read.  And most all the bookwork you will learn with any race vehicle which turns both left and right bases things on over all grip and the rotation of the whole kart along the intended line.  All that to say, all rotation is not the same and when someone speaks of the kart rotating or a kart rotating, you need to understand the context of the word ‘rotation’.

After all that I’m going to repeat myself as I often do and say, all of my posting on here so far is trying to show there is something between deceleration and acceleration.  And it’s totally accomplished by driver skill.

I’m going to end for now I hope with, I’m NOT arguing with anyone and I’m NOT trying to say anyone is wrong.  I think I’m pointing out something which is not normally if ever, talked about on here.  I think it exists, it is seen all the time but never defined and looked at and it is a major driver skill which separates the slow from the fast.  maybe ? … :)
