I'd check out the minispools. Is the vehicle a daily driver? If so check out an eaton posi or an auburn unit. All depends on what you are wanting. I'd stay away from full spools or welding the spider gears if its gonna be daily driven. What kinda gear ratio are you running?

The differential that you're talking about is called a positive traction. Or 'limited slip' or 'LSD' (limited slip differential).

This requires that you remove the "open" differential and install a LSD. At this same time, you would change the gear ratio if desired.

There are several types to choose from, cost varies quite a bit between them all. An Auburn would be fine, as would several others.

But stay clear of spools. Mini or otherwise. Or welded spiders. They ALL solidly lock both rear wheels together, so when you turn a corner the inner tire will squeal because there is no 'differential' to provide the correction for the wheels being locked together. So the inner tire turns at the same speed as the outer wheel- and squeals. And will wear out VERY quickly. The other added benefit is a bad habit of the rear end passing the front end in the rain. Bottom line- there is no place for spools on the street!

im planning on putting 26" rims dub floaters on the car
Yeah. Good luck w/that.

Read this. I recommend a Eaton Posi for most GM cars. You didn't say what kind of car you have. That information would be VERY helpfull.
