The +3mm Wide Rear Straps for the CAT PB offer increased bump handling whilst also providing added stability through higher speed sections.
A narrower rear hex will be needed to allow the width of the car to remain the same. Β To keep the same width the hex width must be reduced by 1.5mm each side.
The team also recommend shortening the rear link on the hub and softening the rear spring by one rate when changing to these straps.
The straps must be used as a pair, U9571 and U9572.
You will find the most benefit from these straps in medium to high grip conditions.Β
