Solved - Help With jbeam - Can't define front & rear pressureWheels separately

SOLVED! See below....
-----------------------------------
Hello,

I've been working on my FSAE car for a while, and I'm currently converting it from a single jbeam file to one with multiple sections via the slots system. I decided to define some temporary wheels to give it a short test run.

There is a problem, however, with defining the front and rear pressureWheels; Even though I defined both Front and Rear wheels in separate sections (susF.jbeam, susR.jbeam etc), the Front section is used exclusively to define all four wheels of the vehicle. This behaviour also links up both Front and Rear brakes; the Rear Brakes section is effectively ignored, and lock up easily even during light braking. Any pressureWheels and braking values I define in the rear section are also ignored.

It's ruining the braking stability of the car, and I'm at my wit's end! I've included a snippet of code and the .zip file, and any help would be appreciated!

You'll probably get a better picture with the .zip file; sorry if I'm a bit unclear on some parts, it's my first jbeam project since 2015....

 

The problem is solved! This post can be left up as a guide of some sort;

In the same way that the brake properties are cancelled out in the parent susF section, the default wheels can also be minimized by adding a section that defines wheels and tires of 0 radius.

"pressureWheels": [
["name","hubGroup","group","node1:","node2:","nodeS","nodeArm:","wheelDir"],
//cancel out default generic wheels
//general settings
{"radius":0}, //Radius of the tire nodes
{"hubRadius":0}, //Radius of the rim
{"wheelOffset":-0.1}, //Offset from the original position(Left/right)
{"hubWidth":0.2}, //Width of the rim
{"tireWidth":0}, //Width of the tire
{"numRays":16}, //The amount of nodes to make the circle, more may result in smoother driving, but at the cost of performance, weight & stability

This was added to both susF and susR parent sections, then the specific wheels were defined in a wheeldata slot one level below.
