U9214 and U9256 are the kit rear straps for the CAT PB.
U9289 and U9212 increase the pin height by 2mm compared to the kit rear straps for the CAT PB.
U9212 or U9571 are the 3mm wide than the kit rear straps for the CAT PB and 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. 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. You will find the most benefit from these straps in medium to high grip conditions.
The straps must be used as a pair, i.e. U9214 and U9256, U9289 and U9212 or U9571 and U9572.
