This week we are pleased to tell you about a new addition to our range of suspension bushes for the BMW E46and E85, E86 Z4 vehicles.
Our current range of bushes for the front wishbone of these vehicles includes PFF5-4601 that features polyurethane inner and outer and PFF5-5601 that features a polyurethane inner bush and aluminium outer shell, designed as a high performance option.
Today we are introducing PFF5-5601G, PFF5-5601G-60 and PFF5-5601GM3, new variants of existing part number PFF5-5601. These new parts integrate caster offset found in Z4M vehicles to provide an additional 0.5° offset over the original concentric bushes found in the E46.
These new parts feature a low friction polyurethane inner bush, forming a bearing surface between the new CNC machined aluminium outer shell that gives increased performance and limits changes to the vehicles geometry.
PFF5-5601G Front Wishbone Rear Bush, Caster Adjust fits into original mounting brackets with a 66mm diameter, bracket and bush part number: 31126783376.
PFF5-5601G-60 Front Wishbone Rear Bush, Caster Adjust replaces the original bush in all vehicles with a 60mm diameter mounting bracket except M3.
PFF5-5601GM3 Front Wishbone Rear Bush, Caster Adjust replaces original bush part number: 31122229857 found in M3 vehicles and fits into original mounting bracket part numbers: 31122229623, and 31122229624.
Testing during the development of this bush has indicated stiffness gains of 128% compared with the original rubber bush.
Our Black Series part increases stiffness by 28%, to give an 190% increase in stiffness over the original part. The result is that the car experiences fewer changes in its geometry for a given load for more predictability and improved performance of the suspension.
Powerflex offer improved reliability over original parts and of course carry our Lifetime Warranty.
