who knows about diffsonline?

Indo Rider · 06-02-2014, 08:14 PM

Anybody ever get a diff from this place? Seems legit but never heard of anyone getting a diff from them... Any info appreciated.

Yes I do, I bought from Dan at Diffsonline, he is actually one town over from where I live. Dude is legit, builds racing diffs for all kinds of cars, particularly E46 and E9X M3's. Sold me a wavetrak when I owned my 135i. He had my car in and out of the shop in less than 5 hours.
Quick and easy

Where are they out of?

Dan uses Bavarian Performance Group in Winchester, MA for the installs. I'm in Medford, so it was pretty easy. He has prebuilt diffs for quaife and wavetrac.
Cool guy.

Just about every BMW racer east of the Mississippi (and many west) get their diffs from Dan at diffsonline. He's extremely knowledgeable and stands behind his product.

FWIW, I replaced a Quaife diff on my supercharged '99 M Coupe with a built diff from Dan. One of the best mods I ever made to the car.

We use Diffsonline for ALL of our personal cars and any race customer who is serious about lowering lap times. His custom Grand Am E90 diff was flawless for our 328i. Absolutely no come-backs for noises or gear whine whether on the street or fully raced. He builds Wavetrac and Quaife, but the only diff for any serious track use must be his custom Salisbury unit.

I have a Diffsonline 3-clutch limited slip in my 335. It puts down power out of turns like I never thought possible. No noise, no groan, no whine, nothing but perfect. Just put it through the paces around Summit last weekend. Full throttle just after the apex even on street Michelins.

I've bought from him and he definitely knows his stuff
