Haven't been aggressive with selling, but would like to find this one a new home. Make me an offer!

FYI, the newly-released Garmin Catalyst 2 is *legal* in spec. Spec already allows v1. V2 is still GPS-only so we will allow it. If any CANBUS data module is added, we will re-assess, but assume that CANBUS data to a Garmin is not legal until said otherwise.

If it is not too late, FDF Motorsports (eastern Canada distributor) have containment seats in all their cars. Do not recall the brand. Their cars all have halos. They can certainly give you advice.

Can we get some clarification on the intention for the rules governing allowed sensors?

Previously it was:

Now it is:


Is the intention to control the sensor types, and that Rush will be expanding over time the types of sensors available for purchase? Or, is the intention going forward that none of those sensors should be used?

If those sensors will be allowed, and we already had them, are we required to remove them until Rush offers an equivalent, then obligated to purchase new ones?

It would be great to get some insight into the intended sensor suite.

You can declare these via the Tech Variance and we will have a look at it. We wish to keep the playing field as level as possible, and I have no interest in making people pay twice for the same equipment.

v1.7 includes additions for the Fire Laps Fire Link device, and further clarifies that live telemetry is not allowed (however camera feeds, without telemetry, are) -- and that we will be making an affordance with Fire Laps to ensure that live telemetry is not available to teams during sanctioned events.

David,

Its worthy of discussion for sure, so thanks for chatting about it, and its an age old debate in racing.

Just so you know, I don't have crew or a crewchief either. I use those terms to the refer to the roles one plays when not actually driving. I am doing crew chief things prepping the car in between outings and when adjusting it between sessions. In the past I have played that role for others alot tho. Most of my experience is only in spec classes.

I could back the idea of individualized setups if it was mandatory for it to be shared with the entire paddock, so that those who cannot afford a crew and crew chief can have the opportunity to make the same adjustments on the car themselves and try it out.

Otherwise, having setups and pads that are fixed or very narrowly adjustable is the best way to ensure that the series truly is about driver skill rather than who has more money to spend to buy pace.

I confidently can say that spec cars' performance envelopes are from the physics of the car. Grip, HP, drag, weight, weight transfer, and CG. The RUSH concept has done excellent defining these. I also will say that executing lap times from said package is all about the car interacting with the driver in a way that the drivers brain makes sense of. You can see this everywhere from Red Bull in F1 to SM in club racing. So, the point of my post is that I do not think RUSH should go down the slippery slope of mandating the feel of the car. To me, drivers skill is about feeling the grip and making the most out of it by tuning the feel to your preference, then executing a lap at a high level.

For example, Braking is 1/3 of the inputs a driver has control over, some like light touch brakes and some like the opposite. Some like a very high initial bite, some don't. But either way, the braking limit of the car is the same.

A steering example is some drivers like a pushy car, some like a pointy or loose car. But either way, the cornering limit of the car is the same.

I have seen over and over again, close racing where the front runners are at the opposite ends of the tuning window for feel, ( If they had to run each others car, they slow way down, that experiment has been done, alot). So, I am encouraging RUSH not to mandate that out of this relatively new class that is just getting momentum.

My .02
