Dry, wet and extreme-wet tyres 11 Sep 2005

Dry, wet and extreme-wet tyres

Conditions at Spa threw tyres into the spotlight. This drawing illustrates the two extremes. Dry tyres have four longitudinal, parallel grooves. These grooves are 2.5mm deep, 14mm wide at the top of the groove and 10mm wide at the bottom. Extreme wets, only usable under instruction from the clerk of...»

Wet and dry conditions - ride-height variation 11 Sep 2005

Wet and dry conditions - ride-height variation

The teams faced a real dilemma in Spa- they had to set their cars up for the race ahead of qualifying on Saturday, highly unsure whether it would rain or not on Sunday.

Jordan EJ15B - barge boards

A complex design on the latest Jordan for Spa - a double series of vertical shields, coupled with a horizontal fin, triangular in shape. The concept behind this solution reflects its aim - improving the airflow management in this area and making the car's aerodynamics more efficient in terms of the...»

Williams FW 27 - front wing 09 Sep 2005

Williams FW 27 - front wing

The front wing has been one of the more frequently modified elements on the FW27 this season. For Spa (and Monza), a sort of hybrid solution incorporating endplates completely straight in their profile and deprived of the usual side winglet (right arrow). This is because both tracks sport long...»
