Rob, long time no see! im glad you still have the car! we all need to get together again sometime. I believe the break in fluid is still oem fluid, then a flush at 1200 miles, but i could be wrong. Where do you plan to get the gears installed at? PTECH?

My foot was giving problem for a few months. After feeling better, I have to catch up on my other projects. We definitely should get together but holidays are coming fast.

I plan on doing this myself. Of course, a shop will install R&P. The reason I am tackling this myself is I want to replace all the bushings since I am there. The total cost will be around $1500 from my calculation to upgrade to 4.10.

Why don't you guys swap a proper LSD unit while you're in there. the stock unit is ridiculous ...

Wheel speed difference driven pump is as far away from racing as you can think... diffsonline for example sells E39 M5 40% lock LSD for a reasonable offer ...

1200$

This is something that will change the car's character

Out of ignorance, I normally wouldn't agree to invest in such an expensive mod so easily, but after having swapped my entire diff out (for other different reasons), I can attest to this being fact. My new upgraded unit helps put power down EXTREMELY well. I thought my car handled well to begin with, but with the new diff, it stuck like glue; even with 440RWHP!

Another option is Jim Blanton @ Performance Gearing. I'm huge on customer service, and PG blew me away with the seamless process. I told Jim that my car was a daily driver and I wanted minimal downtime. He worked with me to have my new diff shipped on time and within budget scope, as well as gave me a whole month's time if needed to return the core unit for some cost savings. Everything was done within 1 week. Can't really get much better than that!

Thanks for the tip. I might go that route in the future.

that's the way to do it! GB ftw lol.

In any case, I personally chose to stick with stock 3.62 just for more useability. Since I felt like even with my old 3.91s, I was running out of gearing too quick for my liking; and now that I'm supercharged, I would like the option to stay in gear a little bit longer
