This product has been offered since the beginning of KAZZ Engineering and has been iteratively improved over the years to make sure your car is always getting the best!
About the material…
This product is proudly Australian made with our unique D60 polyurethane material. This semi-rigid material has been proven to provide the best durability and performance for your BMW! The material properties allow for superior steering response and alignment control while still being able to absorb noises and harshness’ – accommodating for both comfort and performance – this material is the perfect all-rounder! We recommend this material for all road and track applications.
What to expect…
Unfortunately the standard rubber bushings wear out and perish. This translates to sloppy rear suspension and unpredictable changes in your alignment during inevitable lateral forces (during cornering, braking and acceleration). This issue is corrected when upgrading to our polyurethane bushings and I can guarantee you’ll have no unexpected changes to your rear alignment mid-corner and through transitions. Our feedback has always stated that the rear end becomes much more predictable and less sloppy or snappy. This is credit to the rigid bushing design’s superior alignment control.
About the design…
While developing this product’s geometry it was crucial to consider the unwanted change in alignment many enthusiasts experience when lowering their E36 and E46’s – where the rear wheels will toe-in. These bushings have been designed with an offset geometry to compensate for this. The bushings position the control arm further out to remove some toe-in.
Install tips…
1) We strongly recommend all products are installed by a qualified mechanic.
2) Assuming you are replacing OEM rubber bushings – the hardest part of the install is removing the old bushings. The best way to remove the old bushings is with a press and a round 59mm press tool. Failing this; you can cut the OEM bushing out. Start by removing the centre and then make a single cut along the inner face of the metal shell and then pry this piece out.
3) The KAZZ Engineering bushings are unique and are designed to be designed easily without the need for any speciality tools. The geometry of the bushings feature a stepped diameter. This means you can easily push the first 20% of the bushing inside the housing. This allows you to easily get the bushing aligned with the housing. At this point the bushing diameter is increased for a tight interference fit. You can now press the rest of the bushing into trailing arm.
4) If you want to add toe out; orientate the bushing with the thick sides towards the inside of the car – facing the differential.
