Corning G's with R6's
What sort of sustained cornering G's are folks able to hold in R6's? ...I know there's tons of factors that can change this, but interested to see what the group has to say. By sustained (and really not sure if this is a resonable def'n) I mean something for at least a second or two, not a spike.

Joe, non-banked turns. 1.4 Gs. With aero working well in high sections nearly 1.5 Gs. My car is similar to yours with 275s up front and 315s in the back. I do not currently have the extended splitter on the front as you do, but I do have the same nose.

Same setup as Bob (275/315 R6s).. this weekend at VIR, 1.3s consistently through most corners, with some 1.4G and even 1.5G peaks.

Brian the question is sustained G loads. I think Joe is trying to correlate his on track data for car setup. You need better than a 10hz accelerometer to get good data. Joe what is your dry weight and how wide to did you set your front and rear track? Are you running motorsport ABS?

Long Gs shown basically in the middle of each image.

At a certain point, well developed cars (regardless of type) are capable of seeing similar sustained G-loads....depending on a lot of things beyond the tires. My old '86 911 was VERY well developed and I ran 17inch Yokohama slicks. My 997 Cup with Michellins is certainly capable of higher sustained cornering G's but it's not like one is 1.0 and the other is 1.5. It's also not totally related to the tires. The suspension is just as important as the rubber that's meeting the road. I say this so as to warn you of not worrying too much about the EXACT specs of the cars being compared because the calculations involved in trying to compare apples and oranges is probably only close to being right if Einstein himself was doing the math. Also, G-loads are a good gauge of whether you're near the edge of the traction circle but A LOT of variables can change that number.

Thanks guys... Yea, I'm not looking for some absolute number, just some data from others to compare to.
Bob -- Data system is AIM with new smartycam GPS, and using gps G's. My end race weight for nasa is 2680 lbs. I've seen 1.4 sustained, and a peak of 1.68 coming out of keyhole at MidO. There's definately headroom for more, I just need to work up to it.
Peter -- thanks for the plots. those gt3's are so capable. I instructed a guy in a 2011 gt3rs few weekends ago. that car was glued to the track (stock street tires) and had awesome torque. very sweet.
