So in the test, a 225 track tire was marginally faster on a 9 inch wheel than a 245. On an 8 inch wheel, it was no contest. The 225 was way faster.
I am just providing information to help you make a decision. Stuffing even more tire on the same wheel is not only not always better, but it is...
Great thread which I had not seen before. Thank you!
Already on p. 1 there is post, #18, of an S550 guy who built a custom set up in front of his radiator and dropped his transmission temps from 240 down to a range of 210-215.
So the 7A095B part that is just below the transmission is the transmission fluid cooler.
The 7A095A oil cooler may be there, I have not taken a look but the performance pack GTs and the Dark Horse handling package care (or maybe even Dark Horse w/o handling package, I do not know) have...
9 tests in total, three different tire widths on three different wheel widths.
Adding tire width reduces lap times, up to a point. Increasing wheel width for the same tread width reduces lap times again.
Watch this and see what you think.
Which tire size was fastest?
What was more...
It is not just a preference. I posted a YouTube video somewhere here where the proved it using different tires and wheels.
Wider tires on a narrow wheel (pinched) actually slow the car down on track.
Found it! See next post.
If you are going to add headers, get rid of that 2.25" reduced pipe diameter right ahead of the H pipe. No reason to add free flowing headers but keep that pinch in the exhaust pipe.
I am going to be doing the same thing - The Trofeos definitely do not like cold weather, and I know from having 4S tires on my Audi that they do well during the winter (well, Georgia winter). And yet I still feel like I am going to miss the Trofeos and that absolute sticky grip when they are...
That was at Road Atlanta, in Braselton, Georgia. Due to sponsorship, it is now called Michelin Road Atlanta. It is constructed to FIA standards and can host international events. 2.54 miles with some very high speed sections. There are some large changes in elevation that make the track...
From the photos it still has the 2.25" reduced pipe before the H- Pipe. I just do not understand why anybody would want to keep such a small diameter section but then install 3" H- Pipes. Makes no sense whatsoever.
I wonder if there is a way to put high quality instruments near the larger speakers in the rear. On a day when the road is cold and damp, put it in Drag Mode, start rolling forward, and, before it is out of first gear, just stomp on the gas suddenly but briefly, just long enough to hit the top...
