Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Suggestion
It will give you grip using both rear tires/wheels versus one spinning all the time.
Leading evidence: 'Use rear tires/wheels versus one spinning all the time' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Use rear tires/wheels versus one spinning all the time' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

OK, exactly 30 seconds of searching did not give me a clear answer, can I ask for support?
I am interested in a �real� limited slip for track applications. Step one? What transmission do I have?
Any help would be appreciated. Aisin? Getrag?
Thanks for your support.
I've got a '99 and the package contained codes 220, 222 and 224.
220 LSD Limited Slip Differential
222 Traction control ASR AntriebsSchlupfRegelung
224 Traction control ABD Automatic Braking Differential
Thanks 6MT.
I am looking for the next level of improvements at the track. For example at Mid-Ohio (Keyhole & Carousel), after watching hours of cars go through on different lines...A good limited slip would make a substantial improvement, especially when accelerating out of the turns.
This was the info I needed and I appreciate your quick responses.
Jobyt:
Yes, that option list is the same as my car. From others driving my car at the track, the LSD is long gone and not functionally helping me. Therefore I am looking at a custom re-build for the track, or a drop in aftermarket replacement (Guards, OS Giken, Wavetrac).
Got it!
What other mods do you have to the car?
It feels with the engine in the back the LSD is less needed?
(I never felt the need for an LSD but my car was just lightly modded on 200tw tires).
FWIW Guards told me there is machine work needed for their LSD, not a drop in or DIY affair, their recommendation.
Not meant to be a detriment, from my research, theirs is the LSD you want.
Shoot me a PM if you want more info from my correspondence with them.
Thanks, almost full monoball suspension and currently M/L Sport Cup 2 Tires. I would have agreed with you last year, but this year my pace is picking up. And having Instructors drive my car and mention the benefit is helping me give it consideration.
Thanks, my research (very little) has shown that Guards might not be the best choice for a dual purpose car. Of course, it is still being considered, but dual purpose is still my plan.
Yes, that is the leading plan. A Porsche Motorsports Trans shop in Ohio (Copans) has been very educational for me and will rebuild it with motorsports parts for a reasonable price. They also said it can be tuned to the specific usage desired and should last for a very long time.
My car is optioned the same way. Question is: is there a way to completely disable the ASR and ABD by turning of the TC button? I�ve read that it�s always on in some cases.
Absolutely if you are going to track your car or drive it around locally where you need grip such as on dirty, gravely, snow and wet roads. It will give you grip using both rear tires/wheels versus one spinning all the time. If you only take the car out on dry warm days in town, it doesn't matter.
