drive stubs are what connect to the CV shafts, outputs from the differential/trans. (should be very minimal play in them, give them a 'shake' by hand)
the odd popping noises and lurching at light throttle are what kind-of lead me to this idea...but these symptoms + the others lead me to think the clutch is getting hung up somehow
might be a combination of issues or paranoia after one issue
higher the preload the more skittish any diff. will be at low speed/throttle...if you have driven a LSD equipped 911/930 or 951, or other older Porsche, you know the feeling of a higher-preload diff.... the Guard is seen as the pinnacle of diffs for our cars is used the way it should be, do it!

I see.. Thanks for breaking it down. Cheers!

 

taboo. you owe it to yourself to at least look deeply into how well the wavetrac torque basing differential works on this car. there is no reason it wouldn't perform equally well on your gt2.

while it isn't a guard ( admittedly ) not everyone will be able to avail themselves of all the guard plate type ( and 4k$ ) offers.

while the wavetrac on primarily street and some tracking has more than proven adequate. there are NO "open" differential conditions that might cause one wheel to spin freely for being the least "planted" wheel as in any open diff situation, and it is also an easily installed diff to be shimmed/lashed and it is all of a whopping $1295.00.

believe me when i say i tear *** up and down mountains most every day in fair to extreme conditions and never a slip up/down or even braking. this thing works.

just a solid endorsement for a great product that also carries a LIFETIME guarantee. don't be afraid of it because it isn't a guard or even a plate type. they nailed it with the wavetrac for a dual duty 500rwhp porsche.

i've never heard one complaint, only accolades from others that have done it, while the true track rats will disdain it, mostly until they try it.

just a thought......

 

The Guard is fantastic. No drawbacks in day to day operation. What you want to do is have your OEM diff removed and sent to Guard to have new guts installed. There is no shimming required (since you're already installed) and you get all the benefits of the Guard minus the billet case (the OEM case is cast). The rebuild is about $1500 and about $500 for the R&I. $2000 in all...

 

^ upon second thought.. without any retraction of my last post. there is something that just sounds so "right" about a gt2 with a guard installed lol

btw.. that's a lot less than i remember being quoted from guard when i enquired last year. maybe a diff/core exchange kinda deal?! who knows. i remember being north of 3500.

 

The billet Guard diff is pretty expensive... The OEM diff rebuilt to Guard spec is more affordable. (I did the rebuild version)

 

The OEM case is plenty strong. I don't ever remember one failing. I have the billet Guard. It's pretty much bullet proof. This is what RUF was installing in all their RGTs and Rturbos up until a few years back when they switched to Cup diffs.

 

The rebuild is a lot cheaper as you are paying just for the internals and keeping your old case. What drives up the cost on the full Guard is the billet case.

 

Here's my .02 cents. Now I'm going to date my Porsche habit. Back in the 80's there was an action in San Diego where as a new Turbo owner ( some new owners simply have $ no no real experience with 911 and how they " will" behave ). The new owner crashed the Turbo going backwards......His estate sue PCNA for building an " unsafe " car for the public. PCNA lost the case and $$$$. So moving forward, all if not 99% were set up to plow.....thus if you plow your nice new Porsche into a guard rail....can you sue PCNA for building an unsafe car....no as the counter would be, your driving way too too fast.
So the above statement is 1/2 correct. Now for those that understand physics / dynamics , a Guard or similar is an great addition.

80's ...ya I've been playing with these toys even before that...and is still enjoying and respecting their inherit tendency to over rotate

 

yeah, ya just haven't lived until you've completed a few unintentional circles in a 911

 

Which axis?
