Evo VI – Fitting Powerflex Poly Gearbox Steady

(First posted on MLR forum in July 2015)

I’d thought for a little while there might be a bit much engine movement so I looked into ways of reducing the movement. I saw those top mounted engine torque dampers which are a nice shiny thing to stick in the engine bay but it seems most of them are only that as they’re not a damper at all and just have rubber bushes inside. Didn’t seem worth the money they are for some rubber bushes and a bit of shiny ali. I thought it would be a better plan to actually address the problem at it’s cause, that being the bushes themselves. So I found those torx roll stopper things but they sound like they are a bit over the top for a road car and transfer noise into the cabin so I thought I’d just try fitting a poly bush in the front lower mount to start with. So it would be a bit like fitting a roll stopper but not as hard.

So out came the north south bar underneath. This was a bit of a pig with limited space underneath to get at the bolts. I need a proper lift!!!



The smaller rear looks to be in pretty good condition.


The front one didn’t look so good.

Another fight under the car to get the bar back in place and it’s all done.

Just replacing this one bush gave a noticeable improvement in reducing movement and no noticeable increase in noise transferred to the cabin.
