Advice on Differential/Posi Traction!!

Hey Guys- Not sure if i'm posting this on the correct thread so if im not let me know please. I got a 2008 E92 and looking to get power to both real wheels. Looking for some advice as to what to go with as far as brand/maker and any idea on price. I looked into the DINIAN DIF and it cost around $3,800 installed. I thought that is a little high?? Any advice?? Thanks!!

You want an LSD that fits in our pumpkin. Quaife is one. I forget who makes the other one. should be under 1000 for the part. Install is DIY'able

Install is diyable only if your current diff is bolted and not welded to the fly wheel. Or if you are handy with a torch and a CNC grinder. Unfortunately you won't know until you take it apart but odds are if you are 2007+ yours is welded. I also read accurate shimming is important.

Good read here

Distro in UK from birds. Or VAC or HP in USA.

Wavetrack is the other major brand.

Interesting.....But why not just buy a new ring and pinion (exact same ratio) instead of all the costly machining? Or just get a good used M3 diff and slap it in?

Did you really just blindly through out the, "just slap in an M3 dif?" Y ou clearly have no idea how different the non M and M rear ends and drivetrain parts are. Also, what purpose would wasting money on a new ring and pinion serve when the machining costs will be less to have your current welded one machined?

OP, M3 rear dif requires the M3 rear subframe and a custom made driveshaft. It is not even remotely close to a real slap in solution. As for buying new and unnecessary parts that will still cause you shimming issues for proper backlash and preload...just buy a wave track or quaife from Harold at hpautosport or from VAC motorsport. I think total cost on either of those units WITH machining is 2thousand something.

Check with protuningfreaks. It should be a lot cheaper than 3800 installed

dinan diff=quaife, so save yourself the robbery. Do some research on the different types of diffs available for our car, and how they work. Other than quaife, you can get wavetrac, os giken, or drexler. As far as function, quaife is the simplest diff. Wavetrac, os giken and drexler are more capable locking 2/1.5 way diffs.
