looks like Quaife doesn't make it for the 65, right? What's the best option for this car? Thanks in advance, guys...

 

Check Kleemann

 

O.S. Giken makes one with a $3500 price tag or it can be bought through Renntech for closer to $5k. That to me looks to be the monster to have. It should be the same part number as the S65 for cross reference, but that would have to be confirmed. I've gotten use to driving with traction control off and feathering the pedal so there is only little wheel spin and all the fun isn't cut off. Lots of luck great looking car!

 

Thanks! Will O.S. Giken sell direct? I heard they had exclusivity for Renntech on this part. Also, Marcin at Speedriven can get the Quaife unit for our cars - but the minimum run they will make is about 20 units. Marcin has about 6 folks interested, I want one - if we can get another 10-15 folks interested we can have it. I'll post a group buy thread on this. Marcin said pricing would be similar to the retail Quaife numbers.

 

They sell through authorized dealers(see link below). Do you know where to obtain the stock rear gear size and length? I'd be interested in a group buy, I'd be curious to know if the same diff could be used for all S and CL models with the V12. It would make the chances of a group buy that much better.

Looks like Kleemann modifies your stock unit - based on pictures, you can see spring-loaded blocks being installed between the spider gears. So it's not nearly as good of a lockup as Quaife - there is more slop, something like 50-60%?
