I'm trying to sort that out myself. According to HPA, ALL autos are bolted.......True or no? Because I have an AT..........

I'd probably be looking into it more if I didn't have a full pumpkin and other issues to worry about. Sorry.

Np.....If anything, I'll just go by HPA's compatibility chart for the LSD. It says ALL AT are bolted, the only difference is the size.........
So if I go by that and end up being wrong, then I'd hold HPA accountable since they're MORE experienced than half the vendors here when it comes to suspension/drivetrain. So the info they provide should be more accurate according to Harold @ HPA.

So what are you planning on doing? Sell that and get the right one?

It looks like I should be able to swap in the longer driveshaft they used to match the smaller pumpkin, but I'm trying to confirm if it will bolt up.

I'm still confused as to why someone isn't selling aftermarket ring gears to go along with the differentials they are selling. Me personally, I would love to move to a new diff, but I also want to change the gear ratio. So it makes more sense to sell both, instead of just the diff. I would rather put money towards a new ring gear, than paying someone to machine off the old one I don't care to own in the first place. Since I want to do both, it seems the better option is to move to the M3 diff. A 3.85 gearing ratio would feel amazing on our cars, especially on the track.

Price?

So here's a D owner that wants to know the reason for the huge price difference between an "i " install and a "d " install. Please elaborate. |

One other thing to consider: The cheapest is not always the best.
Quaife is very popular but it is a torque sensing diff. It has its disadvantages: it requires that both tires have some amount of friction for it to lock. If one tire lifts off the ground or it slips on ice, oil, etc then there quaife acts like an open diff. Wavetrack claims that they provide locking even if one tire has no traction. BOTH quaife and wavetrack require that there is torque coming out of the drive shaft in order to lock. This means that they only lock when you are accelerating. If you are decelerating, they both act as open diffs! Drexler, OS Giken and some others make clutch type differentials which exhibit none of those disadvantages. They are more expensive though. My recommendation: talk to Harold@HPA. The guy knows what he is doing and he is definitely the man to get in touch about anything related to drivetrain, suspensions, brakes... Good luck! EDIT: I will be dropping close to $4K for an LSD after the holidays! My business is going to Harold.

$4k sounds a bit much for a differential. The stock m3 lsd diff is under $2k, and it's a clutch type.

+1 for Harold! Bought my Quaife though him and loving it ever since. There is no other vendor on here I'd trust with suspension upgrades.

If someone would make a driveshaft that could be used with the M3 diff it would have great success. For now, fitting an M3 diff requires driveshaft modifications.

I had Harold install a Quaife in my ride a few months back, and I couldn't be happier. It wasn't cheap, but one of the best mods I have done. Service was top notch, and I have been back twice for further work on my E92.
Also nice to tool down the back roads on the way home!

While I'm thankfull for everything HP autoworks has done for the commmunity there are shops who are much more experienced in drivetrain and diiffs installs that are cheaper http://store.vacmotorsports.com/vac-...als-p2324.aspx Its always a good idea to shop around.
