Default Preferred line through T5 and T6 at Summit Point

I've seen 2 different lines through T5 and T6. One enters T5 from the far left coming out of T4, and then drives straight to the turn in at the far right at T6. The other line starts at the center or right coming out of T4, goes through T5, then heads to the far left of the T6 for the turn in.

Which do you prefer and why?

I enter T5 track left.. why? because I drive Flat Out throught T4 and it naturally puts you track left into T5.

If you can get over far enough to the right, you either are not going fast enough through 4 or have a very nimble well set up car. Whether you enter 6 from left of centre or tight right, again depends somewhat on your car and also if you are doing DE or defending in racing

Fast through 4 leaves no other line available for 5 but turning in from the left side or slightly to the middle. Anything else and you are slowing down through 4 to take a better line through 5 (the slowest corner of the track)

Before you say it, yes you do see racers do it sometimes but they are usually trying to make something else happen in 6 or further up the carousel that requires that little extra push there and were willing to give it up in 4.

The inside of 5 is the proper line if you are carrying enough speed through 4. It also is a defensive line in racing. Hard to pass on the outside of 5 with all those marbles out there.

X (whatever)

However if you ain't that fast coming out of T-4 mid to right of center gives you a nice leisurely line to T-6!

Most of you weren't even driving on the track back then, but the late Dick Fleming (retired F4 pilot, great 911 drover, and one of the funniest guys to every live) once said to me that "if you have a line choice going into T5 it's only because you're a pu$$y and didn't go through T4 anywhere near fast enough". Don Newton, Dirk, DR, Tim, and Alan (plus others) all remember Dick and subscribe (whether privately or publically) to his belief.

Dick is on the left in the attached picture, Don Wolfarth is in the middle (a very fast 914 drover) and I'm on the right. If you've were driving back then I was the drover in the champagne 944 NA that kicked most of your a$$es!

Yes heard that many times... think it often when I find myself mid track going into T-5's brake zone

BTW who's the bone ugly guy on the right??? Looks like a squid I used to know who actually came to the track?

After flying out of T4, you still want to move over as far as you can before T5. However much you can move over helps entry into T6. You want to move over as far as you can for T6 also so you can get on gas sooner for the whole complex to and out of T9.

Unless youre racing and someone is on your tail. Definitely dont want to leave the door open at T6.

Let's do a calculation based on some assumptions:

95 m/h == 139 ft/sec
85 m/h == 125 ft/sec

So if the distance from entry of T4 to entry to T5 entry is 1500 ft, the time difference between two different avg. speeders would be

1000/147 = 10.8 secs
1000/125 = 12.0 secs

Diff.= 1.2 secs.

However between T5 entry to T6 entry, let's assume the distance is 600 ft, and let's say your average speed taking T5 from the middle is 65 mph vs. 60 mph is you take it from far left:

65 m/h = 95.3 ft/sec
60 m/h = 88.0 ft/sec

So, time difference would be: 0.5 secs

I guess this why they said T5 is a "throw away corner," meaning don't worry about it too much, just focus on getting T4 right.

For me, a DE'er, if there is such a term, I have seen too many accidents between T4 and 5 that I leave about a cars width of buffer and try to take T5 as fast as I possibly can, even if that means I need to be slower through T4.
