So here is yet another 2 piece Rotor Post. Save yourself now if you feel you’ve read all you want to on the subject. My unique spin on this is that I am not one camp who is fighting against the other camp. I own BOTH.

It’s always been my nature to truly ‘compare’ things on my own, vs just going with “I heard this from so and so”

With this in mind, I set out to find out if there was a difference between srt10 Stoptech rotors and Eurotech rotors.

My findings? Get ready for pictures… :D

It comes down to this, I weighed them both (physically). And surprisingly they both save you the exact same amount 29 lbs. over stock rotors.

So your next question ok, so what sets them apart? Believe it or not, I feel 3 things, and they may seem trivial to most, but to me were important.

1st. Looks: The StopTechs look Generic. I own both and I don’t mind saying it, they just look like any other guys cross drilled or slotted rotors. The Eurotechs scream – High End, in my opinion. They look if you will…like a Ferrari and the Stoptechs look like… a corvette. Both will work, but the EuroTechs scream look at me, while being classy. Also The Hats have a really cool scallop to them where they connect to the rotor, which I think looks really cool vs. Stoptechs simple/generic circle cut all the way around (a pancake if you will).

StopTech:

EuroTech:

11092119505.jpg






2ndDetails: The Stoptechs seemed to be anodized on the hats only, where as the Eurotechs also anodize the drilled holes/slotted sections, along with the surfaces where the pad does not touch/rust. The point in this, is when you wash your car, you will see plenty of ‘rust’ on the stop techs, which your response is, ‘oh that will go away after you drive it’ and you’re partly right, the pad contact area sure will, the rest will not. So you get an inner and outer ‘rust ring’ where as those areas are anodized on the EuroTechs, so NO rust rings. It’s a detail item, but you car nuts will appreciate this one.


EuroTechs:

I'd put StopTech's front and back photos, but they are currently on my car, because I ordered them first. Just imagine where you see the 'blueish' sections on the EuroTech rotor (not the hat), that those will show Rust (bare metal) on the StopTechs.



3nd Packaging: So I got my StopTech first, and I was EXTREMELY excited about them, because I wanted the performance benefit that MikeR said he gained over fellow Paxton Buddy ‘ILLSmoq.’ When I started ripping open the boxes, to my dismay, I noticed that they were 2 rotors in a box with JUST a flexible/Styrofoamish pad separating the hats only (meaning barely big enough to cover the hat, allowing the rotors to whack each other as they please. I immediately started puckering up, thinking oh crap, what if they scratched each other (in another box). Well, I was relieved to find out that had not. But I was still VERY disappointed that something I just blew $1600 bucks on left the STOPTECH factory as if they were common cores. I was relieved they were fine, but disappointed stoptech didn’t have enough respect for them, or me as a customer to pack the rotors better.

Someone else posted these photos of what happen to their StopTechs in transit:
1081.jpg




Now fast forward to when I got my EuroTechs last week. They EACH came in their own box, within each of those boxes each rotor was covered COMPLETELY in heavy duty plastic. Then each boxed rotor got placed with 1 other, and the two separately boxed rotors were boxed in another box. So basically I got 2 boxes, with 2 rotors in each box, which were each in their own boxes, which within each of their own boxes was covered completely in a heavy duty plastic cover.


EuroTechs: (box in a box)

EuroTechs: Once you open the box, you get this (more plastic and protection):
IMG00006.jpg




Looks, Attention to Detail, and Packaging mean to me, EuroTech will be my answer to anyone asking what 2 piece rotor do I recommend. Why? Because I think they BOTH will perform flawlessly at the track, and on the street. So the devil is in the details after that, and I chose EuroTechs.


Oh and dont forget the free license plate cover.. lol.. j/k... but it does come with one, I wont be using it though ;-)

Hope this helps.

You need my address to send the StopTechs to? :D

Nice write-up!

Actually YES!

If someone wants my semi-used StopTechs (easily less then 500 miles) that I paid $1600(+ Ship) for and will let go for $1400 (I pay ship). Let me know. I would much rather have EuroTechs on my car, and only having StopTechs currently on my car is whats stopping me from putting the EuroTechs on.

Let me know !

In that case, I'll save you the trouble of removing the StopTechs and take the EuroTechs. :D

Jon -

So do you have any info on which stops better? or is the analysis all about shipping, handling, and aesthetics?

I was hoping for a performance comparison when I saw the header!

Have had StopTechs on 4 Vipers and counting... I like 'em and they do perform very well but to each their own.

Jon,

I never had a reason or a chance to look but the real difference would be if the rotor part has a stamping on the backside indicating where it was made. I know the Eurotecks don't have any info at all there but do not have the Stoptechs on the shelf to check them (or at home obviously) to check. There are only a few manufacturers that make rotors and the only real difference I have heard anything about is if there is an (Italian?) marking on the back inside of the rotor. If so it was probably the same quality as Brembo rotors. If there is nothing, that's good also since they are a sturdy mainline casting machined by the end user for their line of rotors. If there is anything indicating a Chinese maker you have a real problem :omg: FWIW.

Good night all,

Is it bad if they were made in the USA? Because that what the rotors say on the EuroTechs.

As I stated, I believe they both will perform well. Did you guys think people would be able to tell a stopping friction difference between the two? As far as I'm concerned if they both have high quality hats (I like the EuroTechs better), and rotors, and the mounting hardware keeping the two pieces together (looks near identical), then basic performance isn't the only determinant. I am not sure what else people would compare, besides failure rates. Has anyone had a failure with either?

I honestly believe it comes down to the look you like best, quality, attention to detail and how well they got to you. No where did I say they StopTechs wont work. I have them on my car, so I can chime in the same thing 'got em on my car and they work ..'... but I honestly dont like them compared to the EuroTechs.

Anyone want to take me up on my offer and buy my StopTechs off me? I'll try to get the EuroTechs on in the next few weeks, and give you guys the 'performance' comparison.

No there is NOTHING wrong with the USA! :usa::2tu:

And in my opinion Stoptech to Euroteck it does boil down to what you like to look at, others out there and one piece offerings just beware of cheap materials.

I went with Stoptechs due the the name and history. There isnt much history regarding the Eurotech to find. I just wanted to be sure that if I need a replacement rotor, I could get one.

Also keep in mind that since the stoptechs come on the ACR, we do have performance data on them.

What performance data? where does it exist?

Also, here is a little secret, the Rotors and hats are interchangeable between the StopTechs and the EuroTechs... so finding replacements probably wouldn't be that challenging. Neither one of the companys supports the other I am sure as a alternate provider of Rotors, but as Mark J said, there are only so many manufactures of these rotors, so the hats pretty much have to 'attach' to the 'standard' if you will.

Mark is pretty much underscoring what I said. Its coming down to preference and I gotta say, if Mark inst leaning one way or the other, and he is THE Man for Vipers at Woodhouse, then my findings were pretty much on par. They both DO work well, but for me, EuroTechs look better, wont rust in as many places, and were shipped a lot better (saving me the potential risk/hassle of dealing with returns or accepting scratches/markings).

My vote still stands. EuroTech.

Several mags did performance comparisons, most recent of which was Road and Track I think. They obviously test braking.

I am not challenging your post. I am just telling you and the rest of the readers about my thoughts since I was in a similar situation.

Nor am I challenging you, I was specifically wondering what you were talking about, and where the data was. I guess you mean they tested the ACR with StopTech rotors. Thats kinda ok, but not what I was hoping for. The ACR also has a rear wing and other downforce items that actually help to bring the car to a halt from higher speeds. I guess basically your saying the data exists for comparison of stock 08 viper stopping power to 08 ACR stopping power.

Not really what I was hoping for.

Thanks,

Jon

I am surprised more people here do not have the Brembo 2pc. rotors, because afterall they are stock on the Competition Coupe, and we all know that is a higher performance car then the ACR. Notice, the competition coupe still does not come with Stoptech brakes even after the realationship between stoptech and Dodge from the ACR.

But who wants something from a stock car anyway? 90% of the aftermarket parts out there are better then stock, which is why we normally mod our cars anyway, we want a big improvement.

Hey Neal did you see the pictures I put up on forum. My Euroteck rotor install. They look great!! They are 11lbs lighter than stock rotors. I think I put the scale pictures up too!

Hey Jeff! I just found that thread now, they look awesome. Did you ever hit the track with them yet? I just did last weekend at Homestead Miami Speedway and it was incredible. I will post up pics soon!

Car looks great Neal, of course I'm a little biased :D.

Thanks Mark!!! I still been meaning to make a new thread with a bunch of pics and and whole write up on the car, I will try to do that soon, I just been so busy. But the car is running great! You guys did a great install on everything its set up perfect! Although the inside of my rear fenders are torn up from being so low on the track, lol. But that was a givin, I was expecting that to happen....I am going to modify them and cut the tops out so it wont be an issue though. The height is to good to change.:)

I have had several Vipers with the stoptechs. This time I went with the Eurotecks and I think they are 100% better then the stoptechs. They always look like I just put them on, even after 2800 miles. You can't go wrong with either one, but the Euortecks are BAD ASS!!!!

Rob,

I could not agree more that is why when I get request for pictures of them on the car I send them YOURS! :D I probably need to send you some type of promotional fee huh? :lmao:

Jon,

Your seight differential is from what? Stock SRT rotors or STock GTS rotors?

Thanks,

Stock SRT rotors....

You save about 30lbs for the whole set of 4 aftermarket rotors( Stoptechs or Eurotechs), compared to a stock set on a Gen 3. Its a nice weight savings of rotational mass.
I personally went with the Stoptechs for their history and name. Some say rotors are rotors. Like saying tires are tires. Not true. The Eurotechs might be great. I just wasnt willing to put on a set of rotors on that had been produced for the Viper only a year or so ago. I agree they are beautiful. If they prove to work well and no problems in next year or two, I might give them a try.

I also went with stoptech rotors because of their history(rusty looking at times). I am no track rat and would prefer rotors that don't accumulate excessive rust. Next time I will try the euro tech for the lack of rust. Thank you for the review, very informative even for us posers.
