I know Quaife and OS Giken have LSD's pre-made for the E55, part number QDF7V. I know the mercedes final drives share the same bolt pattern as far as I have been able to reasearch.

I dont know the differences between the slk/clk v6 and v8 pumpkins as far as physcial dimensions but I would imagine it would be worth looking into considering the differential is only 950 and readily available.

Thoughts?

 

I crawled under my buddies E-55. It is WAY bigger in every dimension. Definately wont fit.

 

just in terms of axles?

the subframe mounts are simple to fabricate. what else would need to be done?

 

Well unless you can figure out how to make the rear suspension sub-assembly another 55mm longer and can have custom unequal length axles fabbed up, it's a moot point as it won't fit without removing the whole rear suspension and making extensive modifications.

Sayin' this nicely but does someone need another reminder?

 

the diff is really that much longer? ehhhh, way to go mercedes on part crossover.

 

If you can find somethiing that will fit the C43 read diff I believe you will be golden for our diff. Otherwise....

 

guys ya'll are making this to hard!! we are talking 300$ diff. in price for the wavetrac and its bolt in and bulletproof. stop trying to find the cheap fix and get the permanent fix!!!

 

I thought it was $1100?

 

He said DIFF in price, as in the price difference. I do think the Wavetrac will be a nice diff FWIW. I have Quaiffe diffs in 3 of my cars and with the additional features of the Wavetrac, it should be a bit better than Quaiffe.

 

the price of the wavetrac will be dependent on the # of units to be built. the 1100 is based on the intial #'s needed. 20 units. if they build less than 20 the price may be more. as of now there are only 10 commitments so it may well cost more. thing is there isnt any other fix

i need to correct thgis post. just spoke to devin in cali. 1095 for the diff regardless. the issue will be if theres not enough deposits to show interest then it wont be built. so its either 1095$ or not at all

 

I think it will pick up once it is manufactured, installed, and a proven working component. People want to see and know what they are buying...especially when you top 4 figures...I am saving now....lol

 

well this is the only option for me, next to engineering an r200. I need a clutch type, not a helical

 

I just don't want to leave parts on the track....lol.....

 

Its racing, if you arent breaking something... you arent going fast enough

the wavetrac is a really good unit, but once they build one for our platform, they are going to have like 3-4 people run one to verify fitment, lockup, capacity, etc. So it will be a properly engineered unit. Its just aimed at the drag racing crowd.

Helicals like to unlock around corners, due to varying wheel speeds. It cant figure out how to distribute torque (when purposely spinning the rear end around a corner) thats why I need a clutch type that stays locked up 100% on acceleration and decel

 

kind of like the old detroit locker...I can see that if you are in to drifting...I just want dependability...

 

I want full lock

 

Again I will point out that you seem to be a well informed owner that researches (overly so??) potential mods for your car. But did you even read what the difference between a 'regular helical' (Quaife) and a WaveTrac is?? Go their website, watch the vid, and it will become obvious that the Wavetrac stays locked during ACCEL AND DECEL. It's the non-load conditions where it's open. Can you think of a reason you need a locked diff when there is no appreciable lod applied?

When I was 23 I was certain I knew everything, when I hit 33 I realized I didn't know ****, then at 43 I was just starting to temper the amount I did know with the volume of information still unlearned...

 

and at 56, you don't really gave a .......what others think.....lol.....

 

Drifting requires that the diff be full lock, with no load (off throttle transitions and decel) I've read the wavetrac site. I knew about wavetrac before anyone here mentioned it. A few people have tried them on drift applications with little success. To loading is different, clutch types lock quicker and stay locked.

For road racing and drag racing the wavetrac is perfect, you dont really need a locked diff through turns, just torque biasing. Torque biasing diffs fail horribly in drifting applications, where you dont need the biasing, just a 100% locked diff that transfers equal amounts of power to both rear wheels, not thie inside or outside

 

you just need to get out the welder.....your fix would be easy...but backing into those parking spots wouldn't be....lol....
