Does any one have the wavetrac diff on there c32, (if they make one). I know the srt6 guys use it but don't know if that is the same diff as our cars. And looking for the longegivity of it.
Thanks in advance

Bump, also curious of C55 options from Wavetrac and their reliability

I believe they do a C55 wavetrac. Most likely the same part number as the C63 and later E55's with the 215mm ring gear. It is probably the equivalent of the QDF9V from Quaife. The reliability should be perfect if installed correctly. Even for the track it should be great. Heavy drag racing with a lot of mods, maybe. I am looking at one if anyone can tell me which differential I have.

The C32 is a difficult one. There are two different differentials. One has bolt on axles, one without and the install and additional required parts are not easy to achieve/find. Search for the differences and difficulties others have faced, there are a few threads buried on the forum. I have found the wavetrac info is limited but if you can confirm the quaife part number you can probably find the wavetrac one. Wavetrac themselves cannot tell me which one I need to order for my CLK but I suspect I need the equivalent of the quaife QDF7V.

What year is your C32?

Hey guys,

I reached out to them back in November time, Nathan at wavetrac said

"we do not have any planned production for a 210 axle wavetrac for the C32"

I contacted Vlad at ASP about the Quaife he got back to me with a pretty good price at $1070 shipped but would be a bit more to ship to Canada to me.

Thats for a QDF7V? That is a very good price.

GTA_C63

Not sure about the model number... I asked him about the Quaife for my c32 and that is what he told me.

I think someone on the forum was speaking to him about a group buy....but not 100% sure

Morphh

I have an 03 c32, thanks for the info

Lenin

For a 2003, definitely go with Quaife. if ASP does sell QDF7V for $1070, that's the one you want. Experiment with cooling or fueling but for LSD, go with what has been working for our cars for close to 10 years.

Morphh

The first thing I did was cooling mods, my iat temps are between 8-15 c degree above ambient temp, once again thanks for info.
Don't know if I should go with headers or the lsd.

Lenin

I would go with LSD. LSD will cut 0.2 sec of 1/4 mile time and will make the car even more fun to drive. The headers do enhance the exhaust sound and add some power but the LSD will help you put your existing power to the ground, and that is priceless.

Morphh

That diff will be next of the list thanks

WaveyKat

I have Wavetrac but I also have SLK32 Diff when I did my swap.

These 2 videos are a great for someone who want to install his Quaife at home.
This is exact the procedure for 03 C32 and C55
The 02 C32 will have only one different step, but basically the same.
Great videos!

Morphh

Very informative videos, I have changed ic pump and gas pedal assembly, but I don't think I would do that myself.
But the diff will be my next mod on my list.
Thanks for everyone's input

So, I followed up With Vlad on this pricing of $1070 for a C32 Quaife ATB. Really a nice guy. He is a busy new father (congrats !), but took the time to verify pricing which turns out to be a bit over $1300 (his cost). I can only assume that the $1070 price was for the Chrysler QDF9V (which is commonly sold to folks with 215 axel'd (2004 and later) SL55, E55, etc.

To Be Clear...
The C32 (for which there is no Wavetrac) uses the QDF28b Quaife ATB and is often fitted with the Generic QDF7V. The QDF7V, I have not seen for less than $1399 shipped (this is the best price I have found) http://www.ecstuning.com/Search/Site...ife/ES2561411/

HOWEVER, I became in involved with a groupbuy on Benzworld for Quaifes which put me in contact with Bird's AUTO the official distributor (and field engineers as it turns out) FOR ALL MERCEDES Quaife applications. Opinions vary as to how much difference may exist between the QDF7V and the QDF28b (the latter being spec'd specifically for Mercedes 210 axel applications, purported to include all latest upgrades and tolerance corrections and for all applications I've investigated, includes Mercedes OEM seals as well).
AND, all things being equal, I'd want the latest and greatest for my ride.

But the good news is, after exchanging several emails with Birds (and some time on the phone with James Bird), they decided to lower the catalog price of the QDF28b from 959 pounds down to 876 pounds AND ... give a 15% discount off of the new price for the group buy. .... WHICH translates into about $1211 total (Shipping to any US address is Included in that price). (Worth noting, while they usually request payment by wire xfer, etc, they will accept payment by credit card for this deal)

We only need 5 participants to get this group buy price (if we fail to get 5, they will still give a 7.5% discount to those involved) and while some in the group-buy seeking quaife models for other applications may still be waiting to act, I and another member are definitely in for this price ...
So, 3 more participants and we all get this correct diff for $1211 shipped

I will be posting more info in the Group-buy thread in the other forum tomorrow (relative to how to submit info to Birds to get on the list), but if you have any questions about this now (March 2015, not 4 months or 2 years from now please) ... by all means, send me a PM.

Cheers,
Chris

P.S.This message is intended for C32 owners, however ...
this same diff also fits early 2003 SL55s and some early E55s as well.
