3 reasons why you need a Quaife limited slip diff...

HP Autosport · 01-31-2012, 07:38 PM

There is little doubt that whilst BMW have endowed this car with superb dynamics, there remain significant margins where performance can be improved. We have co-ordinated all of the necessary equipment and expertise to transform the braking, handling, traction and ride quality, so that the driver is able to fully communicate with the chassis, and truly elevating the dynamics to provide the real ultimate driving experience.

Design:

Perhaps the innovative design of the Quaife ATB differential is what has attracted so many BMW enthusiasts around the world. Unlike regular limited-slip diffs that use wearing clutches (eg. the ones used in BMW M power cars), the Quaife is gear operated and will never wear out. The design enables a smooth, progressive transfer of torque between the rear wheels with no fuss, and applies power to the tarmac with maximum effect. The result is a transformation of performance. In 20 years of tuning BMWs this has to be the most effective tuning element we've ever had to offer, which is why it is the first enhancement we advise to all BMW owners looking to increase performance. Backed by a limited lifetime warranty.

DTC interference:

In a recent survey to BMW customers who have bought a Quaife differential, we asked what their main reason was for the purchase. To enhance performance was at number 1, which is understandable. But at number 2, the reason was to eradicate that irritating, flashing yellow light. Dynamic traction control (DTC) or 'electronic braking' has limited the new BMWs to quite an extent, which most of you will know. When you put a Quaife limited-slip diff in the car, it almost removes that light completely whilst working in perfect harmony with the BMW's electronic systems. We guess that BMW had prepared them for a limited-slip diff option, but decided to have them as a unique element in the M power BMWs. The Quaife is the ultimate solution, no question.

Performance:

A single tuning element that increases acceleration, cornering speeds, traction, steering and handling to such a degree that customers say it 'completely transforms the car'. This is why we rate it so highly and have invested so much time and money into our Quaife BMW worldwide project. The majority of people are too interested in getting maximum power gains from their engine, not knowing that the BMW's electronics will restrict them. We can offer combinations of a Quaife LSD and engine re-map/anti-rollbars/suspension kits and more, dependant on your preference and what we would advise for your specific BMW. Our experience and expertise have enabled us to create some M Power-matching BMWs over the years, and now we have a new trick up our sleeve in the Quaife limited-slip diff...

Available for your 325i, 328 and 330i.

FINALLY!

Hooy · 01-31-2012, 08:26 PM

Wow, I'd even searched it a few days ago with no results.

Awesome.

Hooy · 01-31-2012, 08:32 PM

More info please!! pricing, bolted/welded pumpkin info, and more info on "engine re-map/anti-rollbars/suspension kits and more"!

fnckr · 01-31-2012, 08:55 PM

How do I get this installed in NJ? I see an authorized dealer on your website that is MD. Anyone closer? What about a complete final drive with a core exchange?

PM pricing please and what a typical install might cost.

I didn't find pricing for 325\328 at your website. What are final drive ratios, and how about different diff types for these cars (bolted\welded)?

Final drive ratio does not change with Quaife install. All cars have bolted ring gears.

You mean that unlike 335i, all NA e90 BMWs have bolted ring gears regardless of the model year?

Yes, all bolted with the data we have collect to date.

Any change in MPG? (under normal driving that is)

328i M-Sport · 02-04-2012, 03:58 PM

Do you have any information what is involved to install it?

I have done carrier replacements in cars/trucks with a solid rear axle but never in a car like the BMW. Do you need to remove the gears to replace the carrier?

Also, is it going to affect the electronics like the stability control or the e-diff functionality?

No, not at all. You are not changing the gear ratio here, just the LSD only.

It's a typical LSD installation, ring gear, bearings and races will need to be swap over to the LSD.

No, the DSC system is not affected. The Quaife will only make the DSC system less intrusive(less blinking traction control light).

sachal007 · 02-04-2012, 11:08 PM

can u install it as well?

DESI4life10 · 02-05-2012, 12:49 AM

Will this work well with xi cars? If so, does it have a chance for interfering with the awd system.

Yes, it will. It's no different on xi as the LSD adds traction. No interference with the AWD system, you will just experience a lot more traction after the install.

Ballpark on how much would cost to install? I know it will vary on location. Just tryin to get a budget in plan.

Be expecting about 7 hours for this job. Your local shop rate may vary.

darkrom · 02-07-2012, 08:24 AM

There is 1 reason I will not be getting this....You don't give them away free, and I can't afford it

darkrom · 02-07-2012, 12:45 PM

LOL. I wish I could afford it. This is one of those mods that more people would do if they realized how much more they could get out of their car. Indeed a good buy!
