The sway bar is thicker than OEM. A thicker sway bar = less body roll.

I guess kinda like the E39 guys who use the M5 rear sway on a NON M5 I would think. I might give this a try since my E39 felt a lot better in the curves after I swapped it out.

It took me a couple months but I finally realized I live a few miles from a Proper station that has HPR, I go to the same station to fill my wagon with E85. It's nice that they don't over charge for the "performance" diesel, same price as Shell, Chevron, etc.

A fellow X5D owner lend me his JBD to try out until I get deleted/tuned. Running it at 100%. It offers a nice bump in power.

Since I have multiple BMW key fobs from the same generation I had some custom keychains made to keep them organized.

Personalized plates arrived.

Happy to report it is centered, I haven't had great success in the past.

Some pics racked up.

Looks great! I've never heard of high performance diesel before....I'll have to look into that.

Question: does the rack and bike make your rear squat that much or is it just a weird camera angle?

No squat ever since I have rear air. Might be an illusion with my ultra high OEM non-sport suspension.

The X5 hasen't been getting much love with a lot of recent travel, other project wagons, a broken finger, and a new 2mo puppy but I do have some maintenance and mods collecting.
Fluidampr, fuel filter, oil filter, vac lines, and a 3" QTP e-cutout I had left over from a wagon project. I have also been researching and strategizing for a custom intake, a big intercooler retrofit, potential trans cooler, and tuners/exhaust for the deletes.

Buying well designed off the shelf items is great since you know fitment will be perfect but I do enjoy the challenge of a good DIY/retrofit project so I will likely end up retrofitting a VRSF race intercooler and building an RK Autowerk style cold air intake. I know the OEM system is well designed but if I play my cards right I should be able to build a system that has similar filtering properties and intake air temps while offering a shorter piping run. Plus more turbo noises and a unique intake system. Living in San Diego I don't have many worries about excessive water/dirt/etc. Climate is kind to cars out here.

For exhaust I like the ATM since it has an in-line resonator but they seem to be out of stock and have been for a while, if it's not available then VRSF DP with Rawtek mid pipe seems to be a nice setup and I like having the 2 bolt flange in place of the slip on design. Either way the plan is to put the QTP valve as far back as possible, ideally right before the OEM muffler. straight piped M57s aren't too loud but since this is a road trip vehicle it will be nice to have a "quiet" mode.

The Y-pipe supplied by QTP has pretty poor fit and finish with a lot of excess material protruding from the welds, this will need to be ground down to keep gasses moving smoothly. QTP also supplies a monster of a toggle switch that is hard to operate and looks like it should be installed in a aircraft from the 70s so I will be upgrading it to a more elegant/flush switch and try to integrate it around the headlight dial so it looks as OEM as possible.

ATM was out of stock when I went to order something last from them, just give them an email or a call. They ended up having the thing I wanted in stock, and updated the page to allow me to order it. I love my ATM, and I'm betting the resonator on there really helps at some frequencies.
