Here's a random question for you.

When a track has people intentionally drifting on it laying down clear rubber marks across the surface does this:

a) make the track slower (lower grip)
b) make the track faster (more grip)
c) does nothing to the track grip

Matt Romanowski

Rubbered in or not doesn't matter as much as the compounds. When TA runs with some F2000, he rubbers don't mix well. The GY rubber from the Nationwide cars seems ok. Formula Drift doesn't mix at all.

I think it's the drift rubber is designed to have low friction, versus road course tires are designed to have high friction.

That makes sense that actual drift rubber would be low friction.
I'm thinking more when cars on street tires light up the track drifting.

Veloce Raptor

I agree with Matt. All depends how compatible the various compounds are

the track surfice is stationary.....easy anwser

I've driven a few events combined with formula Drift, the first session or two right after(usually the next day as drift is late day or night) can be a little slick in the drift part of the circuit. But it goes away quick.

Drift tires always slide more to enhance drifting and with those rubber laying on pavement its detrimental to having good grips with high-performance tires. On the other hand, laying down tires with high-performance grip will allow better grips as in drag racing.

Of we're talking legit drift cars and drivers, they typically run decent rubber, not all seasons or something. They actually want some amount of grip to be able to control things

having just run HPDE at Road Atlanta during Gridlife...we had the joy of running some sessions right after those drift bros.

First and foremost...they leave gravel, dirt, and car parts all over the track from crashing and going off constantly.

Secondly, they leave marbles/ Other People's Rubber EVERYWHERE on and off the line.

So if you run the same day, yes they slow the track down. Long term? I don't have enough laps at RA to say.

They maybe laying down fluids as well . I think the prep on those cars may not be the same levels that us road race guys are used to.

I've driven on a couple of race tracks that use a 1/4 mile drag strip as one of their straights. The corner leading onto the drag strip near the start line is always extremely slippery. During the driver's meetings, they always warn first timers to use extreme caution on that corner because of the lack of grip; and of cours, they always have a concrete wall there to protect the drag race spectators. Everyone thinks that all that drag tire rubber would give good grip, but it does not; it's as slippery as gorilla snot. That rubber is very temperature sensitive. When it is not very hot, it has no grip at all.
