It’s been about 2 weeks since I completed changing out my engine mounts to the Woodhouse Poly mounts. I wanted to wait a little while so that I could give a more objective opinion of how they feel and to give them 500 miles to settle in.

Let me first start out by saying that I would NOT EVER do the mounts unless I was changing the exhaust manifold(s) or putting in headers. I also think that if you are doing headers that you owe it to yourself to do the mounts at the same time as this will make both jobs a TON easier.

After reading about the difference after changing the mounts, I decided to do mine only because I already had the driver’s side exhaust manifold out as I had a crack in the stock manifold. With the exhaust manifold out on the driver’s side, the engine mount is easy to get at, remove and replace - a real piece of cake! The passenger side mount is a whole different story – especially since I did not have the exhaust manifold out like the drivers side. No matter what you think, prepare yourself for a royal PIA job. There was many times when my language would have made a sailor blush and I had to take 3 or 4 walks around my house to cool off as my level of frustration was thru the roof. There is no room to work, you have to fight to get at every bolt, and you end up removing stuff like the oil dipstick tube, the air filter box, and the top cross member that goes between the top of the two shock towers. No matter how hard I tried, I still had to separate the engine mount from the engine bracket just to get it out and did the same to get it back in. Even after getting them in place it still takes a substantial effort to get the engine and mounts to sit right and yes – I did grind off the extra tab on the passenger side mount. I can’t even imagine trying to get the mounts to line up without grinding off that tab.

So was it worth it – ABSOLUTELY! As others have reported there is a very noticeable amount of vibration right after they are installed – so much so that everything is blurry when you look back using the rear view mirror. After about 500 miles, the vibration that you feel is virtually non-existent. What you will notice is that the Viper feels ROCK SOLID, the go pedal and the "GO" are instantaneous, and you just feel a lot more connected to your Viper. The biggest difference is how solid the shifter feels. When you get on the go pedal – the shifter does not move at all – it is planted in place – and shifts feel crisp. I did buy the trans mount - but am not sure I will install it as everything feels good right now. Again, I would only do this mod if I was doing headers/exhaust manifold work and it is still probably worth every penny to have this job done by one of the Viper experts that have done this project before.

Thank you to Mark Jorgensen for his help with the mounts and exhaust manifold. Also, thanks to Dan Lesser/Viper Specialty for his posted advice and all that have posted their tips and tricks for trying to do this very frustrating mod.

Good luck to all those that are brave enough to do this themselves. I rate the job about a 9/18. Nine beers needed when doing the job and 18 beers to celebrate being done. :2tu:

Very true in every aspect. When I changed mine I already had after market headers so I didnt have to remove anything. Thigs are obviously slightly different on a Gen II.

The result is remarkable. Do the Trans mount. That takes no time and you feel even more connected.

yes they are hard to install. i left the tab but rounded off a corner to get it to set into place. It is easier if you are installing headers at the same time.

Before I put the mounts in, I would mis-shift once in a while...after the mounts I never mis-shifted again.

Thanks for the heads up. I am now looking at doing these but along with other mods; I thought about doing the mounts myself but I won't now!

I had the Woodhouse Engine Mounts in my '06 Coupe and loved the feel.

Now I want them in my '08! Guess I'll have to try to convince my Viper Tech to do some exhaust work for me while he's at it!:headbang:

Is this a big job for my local mechanix with a lift and air tools or should I just have him do the trans mount for now, and wait next year for the headers and engine mounts?

Claude, both jobs will be 1000% easier if they are done at the same time. It's really not having the lift or tools, it's just the space limitations - especially on the passenger side that makes the job a real PIA. Also not sure if it would be worth just doing the trans mount for now, but maybe others will chime in. Heck, it sounds like you're gonna do it anyhow - so why not just do it ALL now?:D

The trans mount can be dont in no time. At least on a Gen II. Just need a jack to put under the drive train while you remove the old crossmember and rubber mount. Bolt the new one in and set it down. DONE

Here's a little piece of advice........DON'T do the trans mount untill you do the motor mounts. You can do the motor mounts and skip the trans mount, but don't do the opposite.

After a few more miles on my '09 I am having the exhaust done. Was also thinking of the motor/trans mounts at the same time. Do these mounts put any extra strain on any other parts of the drive train/ car that we should be concerned about?

I assume that doing just the trans mount would put the added stress on the motor mounts. Since they are rubber and weaker, you could really rip them up good. That is what I am assuming he means.

Doing all the mounts will not cause added stress anywhere else.

Mark is putting engine mounts in my 06. Why the vibration for about 500 miles and why are they so much better than the stock mounts? Thanks.

Any other mods I should consider? I'm still mulling over the shifter.

Chris,

The MGW shifter is truly amazing and would only add to your enjoyment. If your going to keep the car a while the Motons would also make it much more enjoyable with ride quality improvements, looks, drivability ease, and decreased wheel hop (better launch weight transfer with the S/C). Beyond that the Quaife would help keep you going straight under power and make the car much more predictable during acceleration.

There are always more things you "can" do but for the street only you know that there is a few things that won't really help your needs.

Why?

.........

Actually the stress is all transferred to the trans. The stock motor mounts are nice and soft and allow quite a bit of movement (think rotational). If you leave those in place and solidfy the tranny mount (the poly mounts are quite stiff) it's like a crow bar acting on the trans. The best move is to keep the mounts similar in terms of stiffness front to back (do all three at the same time).

So it would make the motor vibrate more? I like. :D
