Road racing differential with higher lockup. I bought a brand new differential and sent it to Devin King at Unitrax Driveline in Anahiem, CA. He replaced pinion seals, output shaft seals and cover O-rings with higher temperature versions and added the Unitrax 300m LSD beveled plates, 300m cross pin and racing Getrag LSD kit. This was my spare, and has never been used. The lockup is not so high that the car is no longer streetable.

If you track or race your Solstice and really want the rear end to bite, this is the option for you. This was worth almost a second in lap time reduction at Mid Ohio, and really kept the rear planted mid corner after turn in. It also allowed full power to be used to before mid corner, hence the reduction in lap time. The price is half of what I have into the differential. $1000 + shipping Bill 440-821-6421

Not trying to pour cold water on your sale, but can you explain the advantages/disadvantages of your diff over a Quaiffe? I honestly just want to know.

I raced the car and tested many differentials. This upgrade makes the car faster mid to late corner. It is also faster in high speed sweepers like carosel at Road America.

I sold the car where it will be racing in the Canadian Touring car series up there. I have a ton of spares etc. that I am selling. I am starting a new build this winter.
