EMB205-5 – Group N Top Mount Buffer – a part of our complete Group N (Grp.N) Engine Mounting Kit that has been designed to substantially reduce engine movement by incorporating up-rated and stiffened rubber components. The kit is ideally used for rallying, racing, enhanced engine conversions and modifications.
Note: Additional individual buffer. Add quantity for more.
We have designed and manufactured this bush to offer a firmer option than the standard item (e.g. reduce engine movement), whilst still retaining some compliance compared to our Grp.A Bush. This product compliment’s Grp.N Full Engine Mounting Kit.
Location: This bush is located within the fork which connects the subframe to the lower engine bush.
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.
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.
