Rigging a Raycast Vehicle?

Long story short, I’m in attempt of creating a Raycast vehicle and my current approach is using springs. Doing more research and performance testing, having multiple springs/constraints seem to introduce a performance hit and I’d like to utilize the more common method Unity uses, so my question will be:

How exactly is my car supposed to be rigged in order to set it up for Raycasting? This seems to be my only issue, I will add I’m a bit new to Vehicle rigging however would be a cool skill to have under my belt. I’d optionally like to walk away from Constraint usage, however the problem I ran to is the weld positioning not defaulting at 0, and would hate to script that in manually per wheel.

Original Model:

My scripted approach using springs (of course, attempted to Raycast the current wheel positions and was going to adjust the spring(s) accordingly):

Any advice/feedback/help is greatly appreciated to those in attempt to help.

Still seeking the correct outreach, tried going out my way with prismatic constraints, can’t deem to find luck.
