Quaife Final Drive Unit for your 135i available at HP Autowerks, Inc.

ARES45 · 11-13-2008, 09:58 AM

Hmmm, I would have track the car a lot to make this worth it.

It may be a great deal in terms of your cost, but that doesn't make it a good deal for what the consumer gets. I guess the E-lsd will have to be good enough for a while.

What happens to the system that applys braking to the inside wheel?

Noize · 11-13-2008, 10:47 AM

Man, a 3.46 in a manual car would be WICKED.

I have a gear calc.

Here are gear speeds at 6700rpm (Power starts to drop off sharply immediately after)

3.08@6700rpm
1st: 40mph
2nd: 67mph
3rd: 103mph
4th: 136mph
5th: 162mph
6th: 186mph

3.46@6700rpm
1st: 35mph
2nd: 60mph
3rd: 91mph
4th: 121mph
5th: 144mph
6th: 166mph

As you can see, this is a ton more aggressive. It would also use more fuel, but probably a lot more fun on the track.

At 70mph in sixth, the aggressive final drive would turn 2800 where the standard would turn 2500.

I would love to be in the market for one of these, but I have bun #2 in the oven, so its not on the radar. But I wanted to post this useful info for potential HP Autowerks customers, because it sounds like an awesome mod!

Nothing, the system will be less likely to activate with the Quaife intalled.

Yes, and a shorter one because of the much added traction.

You will actually be accelerating rather than sitting still.

HP Autosport · 11-24-2008, 11:46 AM

Most of the automatic 135i we have seen have the bolted diff, so all you need for your automatic 135i is the Quaife unit only, not the complete Quaife Final Drive Unit.

And i can recommend it highly, i have done 2x 135i's with ratio changes from 3.08 to 3.46 and it is a great mod to increase the acceleration of your 135i

HP Autosport · 12-10-2008, 11:00 AM

Automatic! You are one of the lucky ones!

All you need is the Quaife unit only, not the complete Quaife Final Drive Unit.

$1695 with free shipping and free stub axle seals.

Fl0rent · 12-11-2008, 12:59 PM

Sorry but what is the difference between the Quaife unit only and the Final drive unit.

Do we buy the quaife unit only and put it in the OEM final drive unit ?

If you have an automatic, you can purchase just the Quaife and install it in your existing final drive unit.

The manual cars have a welded ring gear, thus require a new bolted style ring gear final drive and the Quaife.

i really plan on doing this mod after coilovers when i get my 135i. any chance the 09 models will have a bolted diff? im getting 6MT btw...

No, we have not seen any bolted manual trans diffs since production.

HP Autosport · 01-07-2009, 10:29 AM

New lower pricing for Quaife will be announced soon!

That means a drop in price for the complete Quaife Final Drive as well!

We don't know yet. Still waiting to hear from Quaife...Probably along the line of the previous GB price of 10% off of $1695.

dcaron9999 · 03-19-2014, 08:03 PM

Thread revival time !

Just got my Quaife 3.46FD installed yesterday on my manual 135i. What a blast! Car is still on 205/50R17 winter tires, with Cobb Stage 1 aggressive tune. The 3.08 stock FD to 3.46 FD upgrade provides much more torque in all gears, and rear end does not tend to kick out in hard straight line acceleration.

Cant wait for winter to end over here in Quebec, Canada, so I can experience this fully on 255/35R18 sticky summer rubber at the local ICAR race track.

Thanks to Harold at HP Autowerks for the build, and VAG Motorosports for the install!
