SU Rear Engine Mount Vs. SURE Motorsports

[King-k]

Hi Guys

I haven't been on the Forum for a while now, so apologize if this Thread is a duplicate.

I'm looking to buy a Aftermarket Rear Engine Mount

I'm thinking of purchasing between SU's Rear Engine Mount or SURE Motorsports's Engine Mount

Point of Views of my choices?

why don't you get cpe?

[carbon3]

I too have been trying to decide on the cp-e 60 duro or the sure motorsports street version. Least amount of vibes would be nice.

[ptfire]

Go with Street Unit, can't go wrong.

[eliminator]

go with CP-E, they even have a 20% promo going on right now on their site

[MPS]

yes u can go wrong with SU
i broke 3 of them and other members had problems
CPe is a good choice but it comes with its price



Go with Street Unit, can't go wrong.

[Tokay444]

Sure

[MPS]

is this how you get your post count up ?


Sure

[Tokay444]

That and I have the sure mount and have no issue with it what so ever and it was actually one of the options the op was looking at.

[MPS]

sorry

[McGuyver_3]

just get the cp-e one great quality and even at the 75 duro has minimal vibes

[King-k]

I'm from South Africa, do any of you guys know if they do shipping?

I quick question along with that... What exactly is that Gear snifters, or something like that, that one can purchase with the SU's version?

[King-k]

You Guys say this is the way to go...?

Cp-e

I just installed the Sure mount and so far I really like it. The worksmanship is top notch. I did't like the idea of the SU mount being two piece. Yes, they say that makes it stronger than a one piece but I disagree. I study failure mechanics for a living and see thier design as a stress riser where the two pieces meet. Just my $0.02.

[Tokay444]

It would increase the rigidity of the part, but at the cost of brittleness. I don't like that CP-e uses rubber.

[Mazda3X2]

I wouldn't use "brittle" to describe it.

Stresses of everyday use building and being localized in one spot (ei: the joint / bolt holes) would be more problematic then having them spread out over a larger / smoother surface. This is inherent in their design and has nothing to do with the material it is made of.

[King-k]

Is there than a other Cp-e mount?

[Elusivellama]

If you mean the durometer, then yes, there's a 65 and 75 durometer version. 75 is stiffer than 65 and thus should give more vibes, but in actual use these things will break-in and the initial vibes will dampen down considerably. Going to install my CPE 75 RMM at the same time I install an intake, RA mudflaps and swap out my winters for summers (probably in May).

The CPE RMM is a quality part, solid and well made.

[King-k]

Thanks for all the help!

I've got a AEM CAI which was approved by Mazda Dealers not to Reg Flag my MPS and Warranty still maintain valid.

But now I'm looking for a proper Rear Engine Mount. I hear pretty good things about Cp-e My choice at the end of the day.

Thanks Again.

i have a 75 duro cpe rmm, i don't feel any vibes...

[pacmann33]

Anyone with a mint condition OEM speed3 rear mount they want to sell to me cheap? I want to see if it fits my 2010 2.5 GT hatch...I'm 90% sure it will.

I just don't want any cabin vibes, so this would be a cheap upgrade and experiment.

the OEM speed one will not differ that much from your hatch. I did not notice any difference between the 2 to be honest. I have the CP-E and it has minor vibes at idle but nothing spectacular

[pacmann33]

Which one do you have? 60(65) duro or the 75 duro?

[McGuyver_3]

75 duro

[TriniFyah7]

I ordered the CPE rmm. Got the 65 duro, and chose this over SU because of the one piece design.

[Tokay444]

Yeah, I chose the sure for the one piece design and no rubber.

[pacmann33]

I just bought the CP-E 60 duro mount. Hopefully this vibrates a lot less than my stock MZ3 rear mount with the corksport inserts....that was WAY too much. a lot more vibes than a MS3 rount with corksport inserts.

If it does vibrate a lot it'll be for sale on here in a few weeks LOL!

Stay tuned!

[McGuyver_3]

Yeah, I chose the sure for the one piece design and no rubber.

Just a question but why don't you like the rubber in the CPE mount?

[Tokay444]

Rubber doesn't like the elements, or petroleum distillates very much, and there's the potential for a lot of that under your car. Urathane is less susceptible to those things, and heat as well.

[McGuyver_3]

but isn't the urethane more likely to crack with heat off of the engine and cool down though?

[Tokay444]

That secion of undercarriage really isn't I the direct line of fire for any heat. I more meant ambient air temps.

[alhope34]

Well, I managed to shatter a set of 60 bushings in my SU mount before. About 65,000 km total on them before it broke. I kept trying to get 90 bushings for it as I love lots of vibes and the "stiff" feeling when idling, but they were always on back order. I eventually just got another set of 60's, and even when they were brand new there wasn't much difference from the stock RMM in my opinion.

[Tokay444]

Yeah, the su branded stuff kinda seems as though it's had a lot of cost cutting corners taken.

[McGuyver_3]

I'm not a fan of them using urethane as I think they will crack. In a year why don't we compare the cp-e and your sure mount. I'd be interested to see the difference

[Tokay444]

Sounds great!

[carbon3]

I've been running a cp-e 75d for about a week now, I love it, hardly notice any vibes, Originally i ordered a 60d but quickly called to swicth it to a 75, No regrets, Really puts the power down to the wheels!

[CelestSpeed3]

Rubber doesn't like the elements, or petroleum distillates very much, and there's the potential for a lot of that under your car. Urathane is less susceptible to those things, and heat as well.

I'm going to chime in a little here, I had a complete set of AWR 90 mounts on my Mazda6. These mounts were urethane and super stiff with a crazy crazy crazy amount of vibration. So bad if fact it was quieter in the car to have the windows rolled down while driving. After having the mounts on for about a year, I noticed a few things, the urethane on the driver-side and passenger-side mounts started to dry up, turn white/pink (originally red) and crack. So when it came time to buy some mounts for my 2010 Speed3 I made sure to get the rubber CP-E ones. Other Mazda6 owners who were running the CP-E mounts for over a few years had no issues with them, they still looked new and performed new, unlike mine.

I think you are being a little prejudice toward rubber here, don't most vacuum lines made of rubber last a year long time under the hood. It might be 10 years before you have to change them, I have yet to see any urethane anything last that long. Even with the heat issue, I asked a few friends who studied chemistry and they told me my mounts were drying up and that's why they were turning a white/pink color and cracking.

I agree with the idea McGuyver mentioned in a few years compare the mounts and see how they turned out, maybe I just got a bad set of mounts, who knows.

[King-k]

Any feedback on new SU??? Yay or Nay???

[Tokay444]

See your own thread on the same subject for response.

[King-k]

Haha!!! I'm situated in South Africa.

I'm just trying to fish out those cheaper than other shops.

But no worries. I'll come right, seeing that certain people can't say anything positive...

[Tokay444]

I'm simply saying that two posts about the exact same thing in two separate threads is pointless.

[King-k]

If you read both Threads, you'd notice, that No one actually said which is best.

More Theads, better chance of finding out quicker.:D

CP-e I think is KING! 75A What do you think?:super smiley

Actually, more threads on the same topic will = the deletion of those additional threads on the same subject...:mod power smiley

[King-k]

Haha. Though to be true Zoom Zoom Boy

But so far you guys didn't delete either one. After I said at the bottom of 1 of my posts "thanks, you may delete this Thread"

[Zoom Zoom Boy]

We'll leave it as is. Just don't make a habit of it. ;)

[King-k]

Thanks. My bad. Any point of view Zoom Zoom But???

CP-e well approved to buy?

[alhope34]

Cp-e always makes great products. Can't go wrong. I'm using the Streetunit mount, but that's because I got it second hand for cheap.

[Zoom Zoom Boy]

Thanks. My bad. Any point of view Zoom Zoom But???

CP-e well approved to buy?

No worries.
Also, no opinion on aftermarket mounts as one being better than the other. I'm running the stock mount on my MS3. I don't have an issue with the stock mounts and I've seen too many fail stories with the aftermarket mounts to date. I have the mounts checked on every service and they are in perfect shape. If I do eventually change them, it will be a softer mount if the car stays as more of a daily driver. If and when it becomes a dedicated track car, then I'll change out the mounts to a stiffer duro.

[stillmatic]

just a heads up....the cp-e mount just had a price increase, its now $239 :complain

[Tokay444]

Lol

[SomeGuy]

just a heads up....the cp-e mount just had a price increase, its now $239 :complain

I saw that...wtf is up with that? How can they start charging $100 more per mount? I'm worried CP-E is getting greedy since they're becoming the most popular option for a lot of parts.

I read on MSF that it was because of the high demand for the product. Here is a link to the thread:

http://www.mazdaspeedforums.org/forum/f505/cp-e-rmm-price-increase-72979/

[Tokay444]

Hi demand usually drives prices down. It's probably the low supply combined with the high demand. Jack up the price and you won't have to make so many to keep up with demand.

[SomeGuy]

Just read that thread...everyone is complaining. Hopefully cp-e will get their shit together and not jack prices up.

[McGuyver_3]

INCORRECT, if a product is out of stock and cannot be replenished fast enough as it is being ordered then prices will go sky high because they are limited. But say they lose tons of business and now have to many instock and they try to move it off the shelves then they will hit rock bottom pricing just to get rid of it.
Remember when gas prices hit record high a few years back because of the hurricane? Same concept
Look at GM. They are producing so many cars and they are just sitting on their lots. A car that 3 years ago for example was being sold for 21000$ is now being advertised at 13000$ and still having trouble getting rid of them.
Everyone gets greedy sometimes but guess what Karma's a bitch. If CP-E does not get their act together it could put them in a seriously tight spot

[hatthi]

I just had a CP-E 75 installed. Can't say enough as to how much better the car feels. Better shifting and the engine doesn't feel like it's rolling around under the hood. I bit more vibration at idle and take off for now. We'll see how it settles.

[alhope34]

I had to take my SU mount off last week end. The threads on the inside of the nut actually stripped and slipped to the end of the bolt which caused the motor to keep rocking around making clunking noises.

[hatthi]

^^^^^^^^^^^
Holy Crap!!!

[alhope34]

^^^^^^^^^^^
Holy Crap!!!


Yup. Clunky shifting and leaking power steering fluid, so it was time to take a look under there.

[carbon3]

I considered the Sure mount, But decided to go with a CP-E mount instead, I've had the 75d on my car for about a month now, Havent looked back, Hardly any vibes even at break in.

[Tokay444]

Yeah, same with my sure. Going on three months now, don't even notice vibes. When down there last weekend to make sure all my torqueing was good. It was, and the urathane shows no signs of ill affect from the winter and all that comes with it.

[Mazda3X2]

My Sure RMM has been on for about 1000 kms now. The increase in vibration I had during break in is pretty much gone away now. The vibration I had for the first few hundred kms was a little more than I would have liked (mostly at idle). But now it's much improved and easily tolerable.

[Kris"Speed3"CWP]

I have had the Street Unit 62d on since Aug,2010 no problems only had vibes from dealership to my house, next morning was gone? My kit also came with the solid shifter bushings, an added bonus. There is a lifetime warranty on the SU piece so even if it does let go and I have 15,000km on mine they will send you a new one. Just drive up on car ramps and swap out unit to stock if required! I have had no problems dealing with SU they should just send out a new piece and you ship back old one??

[Blkoutspd3]

Im planning on doing the CPE 60 duro after i do my cobb AP, inlet pipe, exhaust and test pipe. it has alot of wheel hop as it is....let alone after all of that.
