Mazda 6 MPS differential mounts

[shakespeare]

As some of you are aware, I've had a few issues with my diff recently, full story here as this provides some of the background.

http://www.ozmpsclub.com/forum/tech-...solutions.html

Anyway until today I've never been 100% happy with the acceleration in AWD as the replacement diff rear mount Mazda installed after I broke mine had too much give in the rubber inserts, thus causing mild vibrations under most kinds of acceleration which I believe resulted in a power loss (seat of the pants dyno didn't feel quick)

Today I had the following installed:

1 x Turbine Tech forward diff mount, this basically braces the whole forward section of the diff and not the right hand side only. Full details of how this works here Turbinetech
1 x CP-e rear diff mount http://www.cp-e.com/2042.html

Turbine Tech Forward Diff Mount


Stock Forward Diff Mount


CP-e Rear Diff Mount


Stock Rear Diff Mount


In the third image of the stock mount I am pushing the insert, which has moved about 1cm, there is no movement with the CP-e mount!

So what does all this mean, several things

1) I can accelerate (moderate, WOT etc) and not feel any driveline vibrations
2) Diff resonant vibration has almost dissapeared (short test 15km freeway run)
3) The "Seat of the Pants" dyno tells me it's putting more power down to the road
4) I'm loving my car more so than ever
5) I don't think either of these brackets would break (axles might though!)
6) Slight negative, diff whine has increased (marginally)

So whilst this has not been a "low cost" mod I feel the overall outcome was worth it, as it also provides me with "peace of mind" for having broken 1 mount and sheared bolts, I felt a little nervous when I drove her hard! And most importantly she feels damn quick again

Cheers

Good news mate.

For future references... Have you got a approx cost for each mount?

Cheers

Good to see you have a good result there m8

I reckon these are one of those things we should all do before we start modding the 6s, I mean even standard the stock ones seem to break!

Turbine Tech $299 (CAN/US) + $100 shipping

CP-e $249 (US) + shipping +$100 shipping

Both items have a bit of weight and were shipped via Air, probably could have got the shipping less for sea freight. Exchange rate is still good though

Also PM MPS garage as they may have the CP-e mount in stock. Street Unit also do a replacement rear mount, not sure about this one though.

Do you find your gear changing had been smoothed out a bit?

Gear changes are much improved with the CP-e engine mount, acceleration with the diff mounts is smooth and quick

Shakespeare,

I am wondering how you are getting along with this fundemental improvements to the diff bracing?

Have you experienced any further ill-effects from implementing these mods? Are there any discussions you have seen on US forums that have resulted in material failures (i.e cracked diff housings) due to these mods?

I am also interested to know whether you have tried an alternative rim and tyre package since you implemented these mods - I have been reading your other thread about the inital failures, and am interested in your further findings.
Cheers.

Hi mazda6mps

So far so good, though I haven't done any real hard launches, however I drive my car how it should be driven (very spiritedly) and everything is good and the driveline vibrations are almost non-existent. Only thing that did increase slightly was the diff whine but this is not really an issue.

From what I have read from the US, there does not seem to be any problems and when I asked Turbine Tech about the forward mount they have not had any failure reports.

I am now back on stock rims and tyres, due to possibilities of increased stresses with non standard sizes. Hope this helps a bit
Cheers

time to revive an old thread lol

im thinking about rear diff mounts for my car now.

what do people think? turbine tech/CPE combo or SURE dread/juggernaught combo?

what bolts are people using? stock bolts or aftermarket high tensile? what size are they?

thanks i get clunking and banging on shift which i think is linked to the stock rear diff mounts shifting around.
