Would be technically allowed if the tire's manufacturer gives approval to Joe according to the rules. Don't think any tire manufacturer would do that though.

Best solution is make your own I guess...

Definitely DO NOT do this with your hand! Grab a piece of wood or something if you must

Definitely overheating. In my experience, Hoosier tires run best at 60-70 degree Celsius. They can withstand temperatures to about 90-100C but after that they will disintegrate. What kind of...

Although I agree with your entire post, it's always hard to relate all these parameters to one accurate model. I always wonder how much laptime/points you can get from these more complicated models...

I think I saw some pictures of a mould a few days ago ;)

I think the first part of making the design event better is a consensus amongst all competitions on what design event is actually scored on. I know that FSUK has far more focus on manufacturability,...

I didnt comment on the front steering link mainly because there aren't any pictures of it ;) . If there is the same amount of distance in the front as in the rear then I also think it will lead to a...

The tie rod seems awfully close to the lower balljoint on the rear uprights. It will probably cause a lot of compliance during driving causing the rear tires to effectively steer.
What is the CoG...

This can't be true. 1.6 km*18 laps = 28.8km which is way too long for an endurance. It's either 1.2 km (which adds to about 22 km) or there were fewer laps. If there were fewer laps and it was still...

2 endurances? And the best one counted? Or the worst?
Also, how long was the track? Just the standard 1 km?

Teams can have unlimited autocross runs?? What's the reasoning behind that?

Thanks for the info Z! Personally, I have to say I'm slightly underwhelmed with all the numbers though. Had expected teams be a lot lower in weight to be honest. Especially the single cylinders...

Cool. What is the reason for testing? Also, don't you get into problems with scrub and trail and such or is it only on the rear?

I suppose there is no correct answer to what is better. The question is, is it worth the effort? Reducing unsprung mass vs. extra time to spend on other parts of the car. Which grants you more...

Hey Kev,

I'll quote first, so it's easier to explain:

"This looks like a violation of A6.1 and A6.3. For other difficult design areas (such as custom engine) it has been proven to be in the...

Hi Julian,

we tested different compounds yes. I actually have written 2 reports of our compound tests (iteration 1 and 2) and have discussed this during engineering design at all competitions we...

So I'll add in my say on tires:

- On the topic of self-designed tires and different compounds: First I want to say that we (TU Delft) haven't competed on different compounds at any competition...

Looking at your numbers, I find the tire vertical stiffness quite interesting. I think you've taken the vertical stiffness from your tire from the TTC data, but I wondered if you've ever validated...

Tobias Michaels has tweeted that FSG will not have a different maximum power between 2WD and 4WD. Though he hasn't specified if it still will be 85kW.

FS Austria...

I'm actually not completely sure our tires are the best choice (if you had the choice ;) ) aerodynamics wise, since they're quite wide. Our front wing's width is definitely impacted by these rules,...

I think, with the turbo rules and the larger restrictor, the laptimes of the best combustion teams will only decrease even though wings/diffusers/etc. are limited in design space. I'm quietly...

At the design review held at FSG the past week, Pat Clarke and Owen Carless confirmed some of the 'rumors' about the new rules for 2015. I'll sum up from what I heard, but in details I might be...

I agree completely with everything that Julian said.

Congratulations to AMZ for (finally ;-) ) winning FSE. With now ~2 weeks of testing time, FSA is going to be another hard fought battle for the...

So I've ran your numbers Z. From the simulation the 130kg(!) car with 70kg driver with a mu of 1.5 (which is according to our tests quite viable) and a 60% CoG at 300mm above the ground. Without any...

Regarding the weight distribution on 2WD (combustion) cars. If you only look at acceleration then yes, you want to design a static weight distribution as close to the driven axle (usually rear)....
