Looks like my FF will be expensive as £330 including postage from the US and now import and taxes of £85, so its a £400+ item !!!
FF just fill OEM mounts with a hard polyurethane in the void. Just buy your own and do it yourself with some poly roof sealant for £10 and a few hours. Not sure on what hardness to use but you're paying a lot for them to do it for you.Adrian-9iafn said:
I'll see how they are but I must admit I initially thought they were the same price as std, I am sure they will be better than my original, but how much better or worse than new stock I wont know !
That's the thing ^Lots of great reviews for them on Rennlist, but .... if you've just removed 22 year old 65k mile mounts and fitted brand new OE mounts like I did upon buying my car, any new mounts will feel vastly better, it's a bit like replacing tyres which were years old/well past their best (and down to the legal limit) with new tyres of the same brand and of equal performance. Of course they'll feel absolutely amazing !!
So all those saying the FF mounts are a "vast improvement". A vast improvement over what ? 10,12,14 year old 100k mile items ? Well duh, no sh*t Sherlock
Or vastly improved over the brand new OE items the previous owner fitted less than 12 months and 4k miles ago ... ??
Okay, one short trip back from the garage and on a short dual carriageway. Actually quite please alread.
The car feels tighter and more tied down, the transmission, chassis and car seem more connected, with KW suspension this taughtness feels sportier and 'right'.
Idle has some vibration, but not harsh just some low rumble coming in to the chassis
Some NVH coming through as you rev and between 3-4,000 but overall not horrible and I understand this will improve
The chassis feels, taughter and better connected, early days but in comparison it felt as though the drivetrain was floating separately before and now its connected and that shows through in on off throttle, movement between gear change and pulling away.
It feels sportier more GT to the chassis and 'older' 911 in some ways
If I keep the toughness and lose a little of the rumble shimmer then it will be very good indeed. If I don't it's still a good trade for a sporty drive. In my car there is no 'harshness' just a feeling of the drivetrain is better connected and the movement that happened before is now controlled by the chassis and structure.
The 'old' units do look in good condition and still feel pretty tight

|https://thumbsnap.com/dEa8Bi3Y[/url]I took it for a longer run and I found
1. the suspension seems more consistent and better over large bumps, perhaps stopping or reducing the engine pendulum effect has avoided the suspension and engine working against each other on som undulations
2. Definitely feels more tied down and more integrated as a car
3. The gearshift has improved, but not life changiningly
4. Changing direction and weight transition feels more together, it feels more like a newer tighter chassis
5. the sense of some transmission float and chassis being separated has gone (I didnt really know it was there until it went !)
6. The 'price' at the moment is some low frequency resonance, that isn't harsh and feels like the transmission and all that comes with it is simply more connected. I am aware of a more 'gravely' deep transmission resonance at certain times, like revving through 3-4k. It's not horrible or harsh more GT car like

Fitted the upgraded stiffer engine mounts to my 996. Then decided the engine was too high so I had to remove and refit with some spacer washers. These were all included in the box but wasn't sure I needed them. These went in between the mount and the engine to allow it to sit a bit lower. Look how tight the exhaust is here to the bumper. This is without the added spacers. I was concerned throttle body was pressing up onto roof of engine bay. Also fitting had the added problem that these use a big bolt through the mount. Compared to the standard mounts which have a captured bolt so you just have the thread poking down which is solid and can't spin. So when tightening from underneath the top can spin. As a one man mechanic it's not possible to hold both ends so I had to use a spanner wedged in the engine bay for the top side.
This is interesting.
Even the GT3RS appears to use the standard mounts. I'm not certain I am just looing at these pics. So it is possible of course that they are different internally but just look exactly the same.

Interesting I think there are a few rubber choices and different part number the normal mount is 997.375.049.08, I think there is .07 version, not sure how many more versions tbh
Generally with P part numbers the versions should be interchangeable. And once a part is now on version 2 they will stop making version 1. So generally now real difference. There must be a difference but maybe it could be manufacturing changes or supplier changes. Gassing Station | 911/Carrera GT | Top of Page | What's New | My Stuff
