Want to buy Limited Slip Diff for an 8 speed Dual Clutch Transmission.

 

Better buy new, then..

 

I'd love to. I haven't been able to find one. Can you point me to a supplier?
I asked at Acura and he said "um, no". I asked Quaife and they said "...send us a diff and we'll quote you..."

 

Sending to Quaife or Wavetrac or an actual manufacturer is your only option.

The aftermarket and mass customisation is highly driven by sheer demand. The more people demand, or have a perceived demand of a product, the higher the likelihood of something would be produced.

What you're asking for is very rare, utilizing a low demand, and a very high production cost for a newly created unit. Lower costs are only given with higher demand and larger production orders.

Since this would more likely be a "one-off" production, your best bet is to send it to Quaife for analysis and see if they're willing to create something from it.
