Every time I installed a Ford Police Interceptor Sedan (Taurus) in the Police2 slot (regardless of the handling line; I even cranked the brakes up to .99), these cars have extremely weak/poor braking.  I've searched this site a bunch, and Google, to no avail.  Then I decided to try and swap my police and police2 cars, and see what happens; I put my police CVPI in the police 2 slot, and Taurus in the police slot (and swapped handling lines, ELS, etc.), but the Taurus still has nearly no brakes, and the CVPI in police2 slot brakes fine.  I even went as far as to copy pretty much the entire vehicles.ide line from police to police2, but nothing.  Here's the handling line I made up for my Tauruceptor:

1590.0  4.0   85    0.0 0.0 -0.48       0.45 6  0.26      1.0  233.0    0.99 0.57 0.7  43.0    1.35  1.10 15.0 0.15 0.57        1.5  0.8  0.8  0.14 -0.17 0.0  0.5          1.0 1.0 0.8 1.5     0.0  25000         440040        1                0

Here's the latest Taurus I've used: http://www.lcpdfr.com/files/file/3046-2013-ford-police-interceptor-liberty-city-police-department-els7/?tab=comments

Here's the previous Taurus I've used: http://www. .com/gta-4/cars/29330-ford-taurus-police-interceptor-2013-lcpd-els.html

Also, anybody know which one of those handling line values switches between standard brakes and ABS?  I've read different things online which claim different parts of the handling line, and nothing I've tried has worked so far.

I'd say ask the developer.
