This will be tested this thursday on our club track to see the difference in handling and laptimes between the 4° & 6° hubs.
I haven't changed anything to my setup when switching to 6° hubs.
I will keep you informed about the difference.

I only drove the car once since I put the 6° hubs in and that was on a track I didn't know before, so I can't really tell what difference it makes.
Theoreticaly, as a general guideline, one could use a little less camber on the front with the 6° hubs. A little math will give a rough estimate of the order of magnitude. When the wheel is straight, there is no influence on the wheels camber by the hubs caster. At a steering angle of 90°, the caster would fully add to negative camber, so the camber would be 2° more negative on the outside wheel if it was "steered" at 90°. At my car I mostly limit the steering angle on the outside wheel to around 15° to 18°, which translates to a negative camber gain of .33° to .4° for the 6° hubs compared to the usual 4° hubs.
So from that theoretical view I would start out testing with about .2° (for a "middle" steering angle) less negative camber on the front axle compared to a "4° hub standard setup". But then again all that theory may help us nothing and we just have to find out about a good setting "empirically" ...
I'd like to hear about your experience with the 6° hubs, even if it comes down to "about the same performance", because I prefer the 6° hubs alone for the possibility to take out the cardans and their bearings without disassembling the steering knuckles.

Fellas..... below is a Carpet setup that took a lot of blood, sweat and almost tears. This setup is for stock racing 17.5 or 13.5 expert. Stay with 4 degree castor blocks. Often as racers we tend to want to copy other chassis setups while all cars (other manufacturers) react differently to different changes at different tracks, so get out of your comfort zone and quit using yokomo springs, they are not always the ticket. I believe there are tons of great spring combinations out there, you just have to find them. I used HPI silvers on this setup, if your track is high grip then go to HPI blue, if you want to take some slight roll out of the car then go to to HPI pink front & HPI silver rear which was also quick in testing. Again just because it's carpet it doesn't necessarily mean you have to go and strap on a set of yokomo springs.
The 418 is really good.... just put in the time and you will get there. I am working on a mod setup this week on medium grip carpet so stay tuned, but this will be my base setup to start.
Below is my setup that I believe is fast, carries a lot of corner speed, has lots of grip or traction and turns really well. Try it and let me know what you think.

Yes, stop copying yokomo springs! We use HPI and Ride springs with a lot of success on carpet. Ride Red in front and HPI silver in rear.
BTW, that looks like an asphalt setup. Hahahaha

TRF418 Bonus Parts
- Damper Springs – soft & hard, 2pcs. each
Anyway doesn't matter what they are called. But of the new springs included with the kit, the car kit blacks are in the middle, then with the bonus parts you get 1 pair stiffer (yellow) and 1 pair softer (red).
