I knew my fastest lap was quick, but I didn't know this statistic yet! Thanks for posting it janus!
Since the race on November the 3rd I've been doing quite a few things on the updated chassis. Also, I've made a 3D printing order today for an experiment on the front suspension:
4WD Front Wheels! There are many reasons why it should work better, and some why it may not.
Pros:
- Little scrub-radius (distance between steering pivot and contact patch).
- Steering geometry and Ackermann angle becomes a lot more 'natural' (close to current 4WD production buggies).
- The front track is wider (because the tires are narrower, which should increase stability and decrease grip roll to the levels quite close to RWDs and 4WDs (after all the FWD is the only buggy using the wide tires up front).
- The donor parts to achieve a working system (on paper) are a standard piece of kit from a widely available car, so these shafts should produce a lot less chatter than the current driveshafts.
- The narrow tire is less prone to ballooning. Ballooning tires cause for a lot of loss in grip (contact patch becomes very round, thus smaller) and power output is often very contrasting between inside and outside wheel (effectively losing part of the power output).
Cons:
- The narrower tire (ignoring tire ballooning) has considerably less surface area, and as such it may lose a lot of the (forward) traction.
- The front end will not be usable at all events/under all tire regulations.
As such, at the moment it's only a proof of concept.
- The axles make the car 1mm too wide, whereas both rims and tires fit easily within the regulated space.
- Less DEX210 kit parts are used.
