Most racers out here in Japan, including me, run Magenta front and rear or a shore rating of 35 front and 35 rear.
The narrower width will result in less grip.
Narrow = more lateral weight transfer = less grip
Wide = less lateral weight transfer = more grip
Hence, why drivers go for the widest (172 mm) rear end setting.
Ideally, you want to run around 4 mm of ride height.

Algebra tells us that the larger the track width the less lateral weight transfer will happen.
So if your trackwidth is wider, resulting in less lateral weight transfer, then this will keep more vertical load on the inside tire resulting in more lateral grip.
As I explain in the app and mentioned in my previous post, the greater the difference in vertical load between the inside and outside tire, the less lateral grip you will get due to the tire performance curve.

Thanks Martin,

Reason: I screwed up the weight transfer section.
