Question for you guys... my car is tuned up now just shy of 350bhp 390f/lb. I’ve got Michelin pilot sport 4s tyres which were great before the tune but now can’t get the power down in anything under 3rd gear (which still slips a little) in the dry and 4th gear when it’s damp. What do you higher hp drivers put on yours and does it grip? Road use tyres by the way. Thanks as always.
