Wed night Fun Races (2021)

Yeah - Ed was chatting with Petrolhead and myself on Discord and was also quite happily driving a Volvo until you posted a time that was a second or two out of reach - so he changed.:p

The 190e we’re using next ( and hopefully for a while) seems well received so far - but has some odd (to me) geometry. The middle and outside edges of the tyres get disproportionately hot regardless of how much negative camber you use and if you reduce castor (which is near Max by default) too much, you get some ‘flop over’ steering forces where the steering effort doesn’t just diminish if you apply too much lock - it actually feels like it’s trying to add more steering lock…!

Beware the sausage strips on the kerbs too - quite easy to roll the car if you catch one just right:oops:

This is a good demo of how poor the RF2 tyre model is , do a lap on default pressures check temps , alter camber do one more lap and you can see the changes you would expect , do 2 laps and you slide off no grip due to tyre ballooning , drop tyre pressures to min , temps are all over the place and camber changes dont alter this , the tyre sidewalls are so soft due to lack of pressure they roll on the rim and absorb the camber adjustments but the tyres balloon less and now give more grip .
