I'm doing up the tooling to do these in quantity. It will be done end of this next week. I did a test fit part and it looks pretty good, I'll be fitting in my car tomorrow.

Construction is from a closed cell fire retardant rubber that has some sound proof rating. It will not absorb water or oil. An excellent replacement for the OEM wool pad that promotes rust by holding the water against the firewall.

More pictures tomorrow.

This picture shows the cut pad next to the OEM. The ones in production will have the same holes as the OEM for grounds.

of course these are the cause of lower firewall rust thru in many a 914. Debries get caught behind the pad, making the situation even worse, water enters during rain or washing and runs down to the bottom of the pad. and the lower firewall can then rust. I have had some cars with the pad, most all had rust (some near terminal) from the pad/debries holding water. the early cars lacked this pad and none of my early cars had any rust there.

Yes these can make the car less noisey, or restore an ugly old pad, but the cost is you must be vigalent with making sure no water ever gets behind them.

Perhaps one can shorten the pad's hieght, so there is an inch or so gap at the bottom to help allow water to run out.

Also upon install ,make sure all the top clips hold the top edge firmly and securly to the firewall, this will help prevenmt rain/wash ater from entering.

the pad can be a good thing, but be ware of the faults of these pads, keep the backside dry and you will be ok.

If you read the descrition, these are made form a closed cell rubber that DOES NOT absorb water. The water absorbtion was the biggest issue with the O.E. pads. They got wet and had no way to quickly dry out.

Thanks for another great product Mark (IMG:style_emoticons/default/first.gif)

Scotty: Never did I mention anything about water absorption in the pad. The concern I point out is the problem of water and or water holding debries behind the pad. It is very difficult for it to dry out when water and debries are trapped between the pad and the firewall. Any non -breathing pad will have this problem unless they can be sealed on top to prevent water engress, and/or opened to drain / be cleaned at bottom. A closed cell rubber is not a breathable material unless you perferate it.
Take care to keep it dry behind the pad.

I read this and do agree to some extent.

The main problem with the OEM pad is that it traps and holds water against the firewall. It has great sound absorption qualities, but is more potential problem than it's worth. That's why I did the dynomat. I was concerned about the water now potentially being trapped at the upper section and allowing rust to propigate.

True, there is a potential for the pad to trap water behind it...... if you glue it in.

That's why I used the velco to hold it in place. The foam is fairly soft so to make it more durable I used some speed tape. A very simular application to an aircraft installation. The velcro allows some space behind the pad to allow it to breathe.
I can provide 2' of 2" wide velcro (what I used) alond with enough tape to tape yours up like I did, for about $16 as an option.

In a perfect world this pad will keep out water. This would require a perfect seal all the way around the edges. I think this option if the best of both worlds.


The production on these will start late this next week
