Sorry this will be a long and detailed post, because I'm really starting to like the way the car's handling but I'm dealing with a consistent tendency that I can't seem to tune out yet.
And what I mean by that is it still mostly verges on understeer. Now the way I'm driving it (focusing on apexing late and being on the power through the corner) amplifys that but that seems to be the proper way to drive the car.
Car does not oversteer really at all though unless I do something clearly wrong (It would take me jumping off the gas pretty suddenly mid corner to upset the car) but otherwise the rear end doesn't move.
And I'm dealing with mid corner understeer, and I feel like understeer is keeping me from getting on the gas earlier as getting on the gas makes understeer worse, so I'm waiting, waiting, waiting to get on the power, and the rear feels like it has plenty of grip to put down power earlier.
I spoke with Fred
btw massive shout out to him for being the most pleasant individual to work with in this industry by a mile.
He spent about 20Mins with me on the phone and my alignment stats are as such.
1/8" toe out in the front 1/16 toe in in the rear.
Standard BWR sway bar set to the loosest setting.
And Penskes set to the "Race / Competition" recommended settings from BWR.
Tires are 205 Front / 235 rear R888Rs on LSS wheels.
Fred recommended the toe settings and that helped what I would call initial turn-in or the front end changing directions suddenly but on tighter corners it feels like the rear end is dead stable (no where near it's limit) and the front is just fighting for grip.
And thats why I set the bar to it's loosest setting, to help front end grip.
Next thing we were thinknig was to get more front Camber. I already have the V2 arms and no shims, so whats the next step to getting closer to -3 degrees up front. I'm hoping this alone fixes it and we can start adding a bit more bar back in as Fred had suggested.
If not the only thing I can think to do is to go to a 15/17 setup with some 225 width tires up front, but I don't want to spend the money if I don't have to.
Also I'm only reporting about 1.1G of max sustained grip. That seems quite a bit off of what other cars are pulling, but these phone accelerometers are a bit wonky sometimes.
I'm running pretty good lap times, at the local track that I use as a test ground. Last year I was running 1:12s this past session I was down to 1:08 missing apexs and talking to my passenger the whole time (see video below)
Some of that is me, some of that is the changes made already, and like I said I feel like if we could get the car to turn in better, we could take those times down considerably, maybe knocking on the door of 1:05s which is seriously seriously quick, we're talking Ariel Atom quick. Shifter karts do it in 55-58 seconds for comparison. Anything under 1:10 is considered pretty quick.
BTW cold tire pressures are 23F/27R and I seem to be getting my best laps only 2-4 laps in and if you keep watching the video only 5-6 laps in the car starts sliding (4 wheel slide). I don't measure hot pressure/temp but maybe I'm starting at too high of a pressure which is why the car is starting to slide. It was only 60 degrees that day so they weren't getting greasy
Video provided for more detail, vid starts on the second lap out. After one good warm up lap I even comment "Tire's are gripping well" and I'm actually not feeling like I'm going that fast. By the 5th lap the car was sliding around, all of which you can see in just a small number of laps shown in the vid
Any help would be greatly appreciated, I'm really starting to enjoy the handling dynamics of this car and the rear end is dead stable. If I could make it more neutral I think I'd enjoy it a ton more, and drop considerable time off an already quick pace
