Just finished my first endurance race in a 1g DSM!

Ah, extra 10-15 mins between fillups, makes more sense now.

And that's a huge filler neck, nice. How long does that take to fill then? I've never done endurance racing before, is fuel refill the the longest part of the pit stop? Do you need to change anything else during the race? Pads and tires last a full race? I'd like to get into this at some point, but not many teams around here though.

You mentioned street tires, do you run a 140+ treadwear compound that will last an entire race? Or a higher treadwear R-comp like the RA-1 or NT01?
