Phantom Grip LSD

[xnamerxx]

Hahahaha Nah I'm good but if you were very astute with google you should be able to find the car pretty easily, guess I've already said to much.

I guess I just prefer to keep my wheels on tarmac

I've run Phantom-Grips on my last 2 FWD racecars, had zero issues with them, does take a little more suspension tuning as it some times induces more understeer. But that can be resolved easily with front camber and rear toe adjustment. The best set up is the Phantom-Grip with it's optional green springs, but for a more streetable set-up just use the standard springs.

I heard lots good/bad things on phantom grip lsd.
Does starlet EP82 fit yaris?
I know C52 trans starlet while C54 yaris same lsd.
Once they open gearbox maybe installing 300usd phantom grip can be cheaper than 1000 kaaz or os giken or trd.....?
Thanks.

PG LSD essentially acts as a detroit locker

both wheels spin at the same speed all the time

you will eat front tires.

the starlet lsd fit in a yaris tranny?????

Why u say locking wheels seem like eating?
It be the opposite.
Just in case one wheel start spinning and eating lsd applies traction.
Then particular PG lsd always gives torque to each wheel the same.
So sure one wheel spin less than witout lsd.
I mean wheels eat less.
Then I don't understand why the more say lsd break front lower arms.
This time too it should be the opposite.
I mean just when outer arm is stressed cause whole torque falls on that wheel lsd retains that torque excess and transfer to inner.
Maybe this continuous bias can stress arms.
In FG lsd case two wheels are locked so same torque and stress amount applied every time every situation.
It mean less stress less break.
I see this way .
Am I mistake?
Thanks.

itll eat TIRES more

as you make a turn your outside wheel travels farther than your inside wheel. with the differential locked, your inside wheel will skip while trying to cover the same distance as your outside wheel.

i had a friend with a jeep wrangler with a detroit locked rear diff/axle. the inside wheel would chirp on tight corners

i have a friend with a TTE supercharged matrix xrs....had a phantom grip lsd....he goes thru tires at twice as quick as he should. he buys a new set of tires every other year (and that is running dedicated summer and winter tire setups)

PGLSD: great for drag racing, not great for a daily driver

Hello Barber family man.. me too.
Now I know PGLSD eats twice wheels.
Not the problem.
Is lsd really essential?
Has lsd only pros?
Or even cons?
I have low race setup, upper e lower rear bars making chassis stiff and responsive. -1.5 camber, -0.5 front toe, 0.5 rear toe.
Pretty quick on dry, scary on wet.
I can imagine PGLSD pulls car outing corner on gas pedal.
But entering corner braking what PGLSD do?
Does it pull inside or outside????
Does it lock arms 4ever?
Does it last 4ever?
Or it wears

[speed1]

Well
what I mean unless they serious race drivers winning money to tune and retune and on and on--> etc, lsd really necessary.. PG, TRD, OS, KAAZ..
or better fix own camber e toe e work with gas pedal to drive?
I'm not referring to dirt or cross I'm sorry dunno but street/circuit.
Then some say wheels eating some say axles breaking....
Lsd fired!

If you don't know what an LSD does, do some searches and read about its function FIRST.
Maybe someone else on here can, but I cannot take the time to explain all the basics and background information to you.

Has lsd only pros?
Or even cons?

1. YES, even on a street car (in my opinion)
2. Pros: traction/grip
3. Cons: more frequent maintenance, more expensive gear oil, installation cost

KAAZ is the best value, and I have used it myself.
No reason to pay twice the cost for OS Giken or similar in my opinion unless you are seriously racing all the time.

ps. I would never, ever run a Phantom Grip in one of my cars.

Please Master,
what about F/R camber e toe values
on your several world championships winning racing cars?
Really thank u.

You must be thinking of someone else, but it sure sounds good!

what about F/R camber e toe values

Sure, negative camber increases the size of your contact patch, on the OUTER wheel. The inner wheel (the one that is losing traction and spinning) is not helped by negative camber. That's why an LSD is so helpful.

Sway bar helps with this goal as well -- I use all three methods together to increase contact patch and grip.

So U are using LSD. Which kind? Ways? Currently to turn tight I have to steer and back to steer and back to steer while mid pressing throttle. Can I avoid this trick with LSD? Or I have same understeer than open diff? Does it help brake? When brake in turn u have understeer or oversteer?
.. and the truth comes out!
