3.45 Differentials With Custom Locking

Evosport is pleased to announce the introduction of custom 3.45 differentials for the M5. Unlike other tuner's alternatives, who merely buy a ring and pinion from BMW, we build these to the locking ratio of your request. Typically we recommend 40 for the street and 75 for the track. All of our differentials include a 3 year warranty. The best part is the pricing! $2750 plus a core-charge of $1800 which is refunded on receipt of your stock differential after installation.

Please feel free to contact me with any inquiries you may have.

Regards,

Ben

Ben,

Yum. Looks like I found my next mod. Maybe Santa will have one in his bag for me. I love the fact that I can do this myself, and return the core to Evosport for credit. Do you cross-ship, or is the mod done on the owner's diff?

Hi Ben!

Glad to have you as a sponsor-welcome

Would you please explain what you mean by custom locking and how this is different from Dinan's and Quaiffe's?

Thanks,

Najeeb

Ben, I'd love to read your response to this question, as I was wondering the same thing.

Elevens,

We can cross-ship with a core, which is the most convenient method, or use YOUR differential as a core (which requires downtime on your M5).

Najeeb/Lupo,

Most differential upgrades are a replacement ring and pinion upgrade offered from BMW for motorsports applications. These are not built to custom specs and usually retain the factory limited-slip which is rumored to be around 15-20%. I am not sure exactly what the ratio on the Dinan is. The Quaife is not a ring and pinion upgrade, only a limited-slip upgrade. They can build it to your specifications, but in order to do so, they would need 20 orders. After final costs of a Quaife and a ring and pinion upgrade, you would be looking at a more expensive option.

For our street differentials, we recommend a 40% lock-up. What this means is that the wheel which is slipping will still be putting out 40% of the power of the other wheel. A non limited-slip differential would provide no power to the wheel slipping. A 40% lock-up is perfect for the street, as it allows one to power out of the turns quicker.

Thanks,

Ben

rear end ratios

Ben
Since it appears you are building these in house, is the group here limited only to a 3.45, or can you build other ratios?

Jerry

Thanks,

Ben

Ben,

Excellent news on the cross-ship issue. What locking ratio would you recommend for all-season use? I drive my car year-round, and it can get very icey during the winter months around here.

Hi Ben:

What would be the core charge for an E39 540 6-speed equipped with a 3.15 open diff? I may be interested in a 3.45 limited-slip unit, but I would need to know if this would require my swapping out my halfshafts and driveshaft for the M5 halfshafts/driveshaft.

Thanks,
DDB
