Stock FRS Brake Bias
 

Would any on here happen to know what the stock FRS brake bias is, and would anyone happen to know what the optimal bias would be for street use/daily driver.
Does anyone happen to know where to find the brake bias online, I’m sure it’s around somewhere, and seeing that the rear brake is smaller I assume it’s considered front bias on stock.

Just an FYI, but it you post easy to google questions on the regular you are going to get a fair amount of flack around here. Bias info is in this link.

Close to stock is best as it is what the factory ABS is designed around.

That guy's piston size numbers are wrong for the stock front caliper as are his effective radius numbers so that whole chart has some issues.

I have what I think is a slightly better one. My numbers for stock brakes are about 65:35.

With EBD, it is less relevant. They system adjusts front and rear pressures based on wheelspeed, before a more traditional ABS would need to intervene to prevent lockup.

Default EBD is rather understeer biased and makes a bit harder to trail brake and also comes "in package" of eg. e-diff. Thus many on track do pedal dance leaving only basic ABS, and so base EBD-less bias may matter more.
