Does anyone know where to get the lower diff ratio. Stillen no longer stocks it..
 
Out of production unless someone wants to buy 10 or 20 sets up front from what I heard.

Correct and not likely to be made available again. Glad I have it.

:agree:

I was on the fence when Shadowman told me they are out of production so I decide to go for the gears. Great mod! IMO the stock 1st gear always felt too high, like starting up in 2nd on most other cars.
 
I'd be interested if you're looking to build up a list. Well how much was it?
 
I did a 355 in my 08 SRT10 and that was insane. I can't imagine what a 391 in a GT would do.
 
If there is enough demand, I can look into making them.

+1
 
An alternate solution is to go to a P345/30ZR19 - Michelin makes them in the Pilot Sport Cup.

The number of $6500 was tossed out a while back. That is the new price from Ricardo.

A bit more cost effective.

I think I would be in. I had a 3.5x on my Mustang and Cobra but was really looking for a 4.1-ish.

That doesn't include installation. To my knowledge, Stillens was the only authorized place to get the installation done and the only source for the gears.

Correct, not including installation at Stillen or the R&R of the transaxle.
