Ok so first of all I’d like to extend a massive thanks to
@KeedenMcdonald for putting in 100’s of kilometers helping me get this BoP down pat.
I have good news, and some bad news. I’ll start off with the good news.
The good news is that the old BOP wasn’t too far off what we were looking for in terms of balance. That’s about it really.
Bad news, oh boy where do we begin.
Having done a majority of the testing at Bathurst, what we have found is that MR drivetrain cars are completely rooted. A comprehensive analysis of the new physics outlining the issues will be posted below. This is Gr.3 specific.
We’ve had these new physics for over a week now and after gathering the opinions of several aliens, casual players and professional racing drivers, the new physics introduced in 1.39 are a significant step backwards in terms of realism and driving feel. Cars feel far more twitchy under braking, yet when on the power, undeesteer away from the apex badly.
From a personal standpoint, having driven every Gr.3 car with various tunes, conditions and on the toughest tracks, I have concluded that the key factor which has altered the car behaviour is weight transfer. Ironically enough what finally lead me to this conclusion was during a muck around lobby on Route X, where zig zagging the car at high speed was not enough to cause the car to spin, rather it would induce body roll to almost comical levels whilst being easily controllable.
What does this mean for Gr.3? For the most part the cars are still perfectly driveable, however mid engined cars suffer the most from the magnified weight distribution. This is most noticable on corners with elevation. On an uphill corner the majority of the car’s weight is being shifted onto the rear tyres. While this increaces driveability, it creates previously unseen amounts of understeer. Bathurst is our test track. The right hander after the Cutting used to be an easily flat corner for every car. For the McLaren 650S for example, this is no longer the case, even on maximum downforce. The same applies to the left handers at Reid Park and McPhillamy Park. The uphill left hander, from all the cars I have tested, only be taken flat (comfortably) by the Mazda Atenza. This used to be flat for almost every car. A downhill corner has the opposite effect. The left hander at McPhillamy can be taken at higher speeds now, thanks largely to the small dip before the apex.
Skyline to Forest Elbow illustrates most of all how broken the physics have become now. MR cars have always been sketchy under braking, but now, braking for Skyline without crashing is almost impossible. Even when braking in a straight line, the weight has shifted so far forward that the front tyres grip more than what one would expect, and the car spins. The only sure fire way to brake for this downhill section is to apply a small amount of throttle whilst braking in order to shift some of the weight back onto the rear tyres. This problem doesn’t seem to be anywhere near as bad on the FR cars. Tuning doesn’t seem to help much unfortunately. In about 20 attempts of tacking this section at speed in the Alfa Romeo 4C, I crashed roughly 16 times. Going back to the Cutting, the fastest way through this corner now is to slide the corner into the apex, then power out of it almost recklessly. Drifting in other words. Utterly ridiculous. Out of all the MR cars to be affected, the cars least affected are the Porsche 911 RSR, Renault R.S.01, Volkswagen GTI VGT, Peugeot RCZ, and the GT by Citroën.
Bathurst will be worst example of this, as not even the Nürburgring has a section with such a sharp decline whilst on the brakes. MR cars will receive additional weight drops for Bathurst. Unfortunately I cannot promise that the BoP in its current format will provide the closest race ever, and I will be doing the utmost to make it perfect come race day. The 7% weight drop for Bronze drivers will remain in place however the weight drop for all cars will be on hold for now.
I hope by taking the time to read above you will be able to understand my point of view as to why the new physics update is a step in the wrong direction and why this took so long. BoPing is a dfficult and time consuming process and when PD changes the game on a whim without announcing anything, it makes things a hell of a lot harder to accomplish when the changes that are made make the cars feel completely different from what one is used to and would expect from a Gr.3 race car, real life GT3, VGT or fantasy model. It doesn’t matter. Your input is more valuable than ever before, if you have any queries and information that I could find useful, please let me know ASAP, it is much appreciated.
Cheers, Jono.
P.S: This video may help you understand the differences a bit more clearly.
