Bosch Motorsport ABS system = amazing, they take a ton of info from you and deliver something almost perfectly calibrated out-of-the-box.
But be sitting down before you ask the price, last one I saw delivered was considerably over $10k.
Then add wheel speed sensors at all 4 corners, plumb it all, etc...

Good fluid
Good pads
Larger tire contact patch
Good suspension (maintain contact patch)

Last resort = bigger brakes

Oh yeah good point on airflow. I'm ducted & blank-plate'd.

I'm on hooptiedubyo 18's, ala ballar.

So I need new tires. The Avons have on the rear are smoooooooth. Fronts still 75% tread lol (No, I'm not driving it like that)

I'm on stock 16" wheels and plan to stay that way for a while. I need to do a brake system flush anyway, so I'm looking at

Brembo LCF-600 fluid
Pagid Yellow RS29's
Toyo Proxes in the stock sizes
Brake ducts for the front

Should I look at other sizes for the tires? I'm lowered, bump steer kit installed, fender lips are not rolled and I won't do that

IF...you NEED larger brakes: I have 993TT fronts and 944 Turbo FRONTS...on the rears. Bias valve as well - perfection.
