Replaces standard rubber joints and mounts on all the mounting points of a rear beam.
Fitting this kit means the rear beam is rigidly attached to the chassis. Giving a more predictable rear end under heavy cornering and more control during lift off over steer.
Front flexible joints are replaced by acetal bushes (4 in the kit) while rear rubber “sandwich” mounts are replaced with “aircraft spec” quality aluminium blocks with offset studs (2 in the kit). This kit is an evolution and improved fit version of our original BBM-SA-R kit. Unlike standard items, our uprated items will not wear out!
This modification is a real benefit to a track orientated 205/309. It will also benefit a road car with respect to handling characteristics but at an expense of a slight increase in road noise experienced in the cabin.
This is the one bush which gets over looked when the engine mounts are uprated. The original bush is usually worn and allows unnecessary engine movement for race/rally/trackday setups.
Location: This bush is located within the fork which connects the subframe to the lower engine bush.
Suitable For:
Fits all 106 and 205 models incl. GTi
Direct replacement for original
For a more compliant version of the bush, take a look at the Grp.N version.
Shims are placed behind buffers to space them closer to the top engine mount.
Fitting the correct combination of shims means, as the engine moves under acceleration / engine braking the top mount can come into contact with the buffers sooner and reduce any excess movement.
These can be used with OE std buffers or either of our Fast Road or GrpN Style replacements.
