View Full Version : Formula A - locking wheels physics (well, not locking them)

Hi All

In the formula A if you go out in the wet (and dry but more pronounced in the wet) its very tricky to lock the wheels up at high speed

brake pressure at 100%
60% bias to the front

Full braking and the fronts only lock at about 40 MPH

I would think in reality they would lock much earlier than that as the down force will not increase the grip in the rain


Also do the AI use DRS all the timer ans KERS ???

Cold carbon brakes maybe?
Check telemetry for brake temps. See if they lock >450c

brakes are up to temp

Are you getting full brake application? Red bar at the top of telemetry goes full when you hit the stoppers...
Downforce works regardless of wet or dry. That said the rain tires are a softer compound and have a lot of grip even in the wet.
Read about a tire test once where a Bridgestone set stopped the car in a shorter distance in wet than it did in the dry!
Not sure how it all works.
I'd also imagine the tires would lock much easier/ sooner in Formula spec Carbon brakes. Who knows.
Tire model is getting big updates through patch 5/6 though.

Why wouldn't it increase grip? The harder the tyres are pushed onto the asphalt the more grip, irrespective of the condition of the asphalt. Overall grip will of course be lower than in the dry.
