Adding LSD to non-LSD car
 

I am looking for some advice on which would be the better way to go.

I have been working on my HHR build for some time. I have the suspension and brakes done, and solid motor mounts. Traction in a straight line is adequate with good tires. But I am still having issues in turns.

Would it be better to have a quaife installed or just pick up a used G85 transmission?
I know the quaife installed by itself would be significantly more expensive, but I need to upgrade my clutch, so I figured I would have it done at the same time to cut down on labor.

I would like to get all of this sorted before I start adding anymore power.
Any help is appreciated!

People that can help will want to know: is this a daily driver or a race car, what kind of competition, what "issues in turns"?

I don't know much about it, but wouldn't LSD make for more problems in turns? I thought LSD is for straight line acceleration.

you're thinking of an actual locker, where it locks both wheels to turn at the same speed no matter what. LSD is a "Limited Slip Differential", which puts power to boths wheels and allows the wheels to "slip" when cornering, so you don't get wheel hop.

That is not a locker but what's called a spool. A locker will unlock when going thru a turn. The ones I knew about did make a clunk or loud click when the unit re-engaged when going straight from out of a turn.

Is it possible to post pictures of the install? Would like LSD in my automatic.

So how do you know the parts you showed will work in an automatic?

I am going to guess, but you might need to row your own gears for LSD. I don't personally know of LSD applications in FWD automatics. I hope to be proven wrong...
