S197 3V Fabman's build; How did we get here? Build Thread

[ArizonaBOSS]

The CorteX rear bar is great. It does NOT have a lot of rate--so it's equivalent to a very small bar--but the quick adjust is VERY useful especially for test days or different tracks, or just fine-tuning the balance of the car.

Keep in mind that what might work on a production car that has suspension pickup points mandated by rules prolly doesn't apply to Frankenstang that has been completely redesigned, the small or no bar I think worked for him back in the day, really no longer applies. BtW what does that vette weigh, and is it in your class?

Did you get anywhere with Big John?

Haven’t called him yet, super busy at work. Will call tomorrow.
That vette is in our group but not my class.

Im just looking to limit some of the diagonal weight transfer, I'm hoping this works without loosening the car up. It’s hooked on exit and I don’t want to sacrifice that but I’d sure like to reduce the roll and fix the mid corner push I seem to have developed. It’s killing my corner speed.

I tried an 18mm bar late last year and it was terrible, made the car very skittish to drive so I have been sitting on this cortex bar waiting for a good opportunity to try it. Friday is a test day at laguna and Sat/Sunday is racing so we’ll see if I like this setup soon enough.

if an S197 doesn't have body roll it doesn't have handling.. lol

True for a mechanical grip car but an aero car has other dynamics.
A big splitter w/tunnels and undertray needs to have a stable platform.
If the body is rolling the splitter isn’t working.
It needs to stay fairly level with the ground to be effective.

Back in the day, when F1 went to tunnel cars with sealed skirts, they only had about a 7% slip angle before the tunnel stalled. It was kind of weird, where the faster you went, the better the car stuck until.. you know.. " the thing".
Which resulted in sealing skirts being banned and the tunnel effectiveness minimized.

Looks like a good field is building....still a few regulars that haven't signed up yet.
45 cars in our group so far. Should be exciting.

Nice of the BMW class to allow a Mustang and Maserati in.

I think most of those guys are from NASA looking for some track time before Nationals...just like we are.

Just treat them as German traffic cones!! Well, actually I have found the E46 M3 cars to be faster then the torque less E90 M3's
