FWIW, most of the team is not going past 26* on the T4’20.
I ran 26* at NYGP, while Drew ran 23*. Both cars were pretty equal on pace, however my setup required a bit more rear stability than his.

I always set the steering throw with Epa. I limit left and right till I get the same throw, e.g. 25.
My son then uses dual rate as a last setup change. If the car oversteers he tunes down the d/r on his tx by 5 points or so till he gets the sweet spot.
This means however that the car will have less steering throw on the track then the 25ish on the setup station.

Not the max throw you set the car to have in the TX, which you are able to manipulate with DR? The reason I ask is it seems that either some of the people I race with, or myself, misunderstand DR. I always set my cars up for max steering throw to be at 100% DR, then dial down the DR to get to the steering angle I want on the inner tire.
hope this helps!

From there I check that each wheel reaches the same value on the inside wheel when steering left and right. If they are uneven, I will adjust with the EPA in the transmitter. Ideally the EPAwould never differ by more than 15%. I do this with my dual rate set to around 90% so I can increase or decrease by a few percent while on the stand; knowing that this adjustment will not be entirely even, but could help me determine if more or less throw is required when I check/set all of this for the next run.
hope this helps!

I race mostly asphalt, so I like to have up to 28 degrees available at maximum, hence I like the aluminum steering arms. Also, I never drive lock to lock on the transmitter wheel, unless it is needed. Everyone has their own driving style, and I assume they will set their cars up accordingly. When racing carpet, I always turn my EPAs down.

Just to make sure this is clear, the team is not using more than 26* throw on the ‘20. For the ‘19 and earlier models it was not uncommon to see up to 29* throw, but no more than that. Since this thread is dedicated to the’20, I originally only shared the value for this car.

From what I have learned at the track, essentially(but not always true), is that less dual rate = faster lap times, which I think is because of the reduced scrub angles of the tires.

Setting the dual rate to 90% is actually step 1 of what I posted earlier. EPA is used to fine tune the left and right balance. So at 90% dual rate, my inside wheel only reaches 26* of throw at full lock.
