I've been searching for a couple days and can't seem to find anyone who manufactures a spool for the 350z. Does anyone know of a company I may have missed?

 

Do you mean DS loop? If so ask the guys at dynosty.

 

No. I can custom make my own hoop easily. I am talking about a spool in the differential so the wheels can't move independent f each other. Many have welded their diffs to do this. I realized that on my fastest runs it still felt like I was kicking the tires when in reality my LSD was not putting equal power down.

 

Interesting, so you're making it a track-only car I would assume. Wouldn't a clutch type LSD get the job done without killing streetability?

 

Lol. Have you seen my car? It already is a track car...

I would just run a clutch type diff at 100% lock-up. There are none, that I know, off the shelf spools for our rear diff housing.

 

As you said, everybody just welds them. That'd be the easiest way I'd think.

 

just get rid of the IRS and run a ford/chevy rear end.

 

Lincoln or Miller works when others don't.............................

 

Seems like a large investment for minimal gain though.

 

I have seen your car and vids, ect. I wasn't sure if you ever drove on the street.

 

Have to agree. Going to a 3 or 4 link with a ford 9" would be my choice.

In the long run, maybe not.

 

Unfortunately I doubt a solid axle will help me much. I could simply lower my nitrous activation rpm and get into the 1.3 60fts and beyond that there is no gain. Is there a way to tighten the slip on the stock VLSD?

 

I would definitely go for a spool over a welded diff. A spool would give your diff a significantly improved polar moment compared to a much heavier/bigger radius welded diff. Basically you'd lose less power through the driveline and be able to spin it up easier. A place like Moser would probably make you a custom one for a chunk of money.
