I wouldnt recommend driving on the summers, terrible traction and they will crack with the cold weather. If you dont want to change out tires move to continental DWS06+ these are great all season tires and provide great tractions in all weather conditions.
Has anyone put in the Delrin Chicane Shift Knob from Hybrid Racing? Im about to order a shifter and want a new knob when I replace it, so curious thoughts. Delrin seems nice when it comes to heat and cold.
