Finally got around to putting the 20x11's on

I could get to a point I would find out how bad it understeers. My point is the stock handling of at least a 4.6 is more than adequate to handle any reasonable street driving without an understeering shortcoming. I am including going at least twice the speed limit going up a 3 story curving entrance ramp at the point where the tires sing. On the street that is where my pucker factor says--that's fast enough dipstick those are not soft walls and you don't have a parachute.

Just to be clear. I do not condone finding the limits on the street. Autocross events, on the track, etc. okay. I did not drive my X or any of my vehicles anywhere near its limits on the street or otherwise.

My pucker threshold is probably much lower than yours!

I've read good reviews randomly online, so that's why I went this route. I'm not taking my X5 to the track, so I weighed the price vs overall goal of simply wanting it lowered. The hardest driving I do is going to Bimmerfest, otherwise it's just a DD for me.

I got a good deal for $950 shipped and he included rear adjusters, something about making them easier to get to the back settings. I won't be installing mine for a few weeks since I'm moving to a bigger place...there's never enough space in the garage, right

Nice! I LIKE THIS

[m5james]

Just popped into my head, but how does this affect alignment. Like do I need to get the KMAC camber pieces for $380 so I don't roast through tires like no other or will everything still be able to get aligned like normal by just taking it to a shop?

The coilovers will change the alignment unless they are adjusted to the same angle to the tires as was the existing suspension. Since at least part of your goal is to lower your X the alignment will change. Lowering the vehicle will result in more positive camber (increased wear on the inside of the tires).

I suggest getting your vehicle to the ride height and ride quality you are seeking, drive it for a hundred miles for verification and then have it aligned. That way you should only have to do it once. If the setting on the coilovers does not allow an in spec alignment you can make the decision to either accept an out of spec alignment or potentially make adjustments, settle the suspension and complete the alignment.

Any word yet on these coilovers? Would love to hear your thoughts on them

Lowering the vehicle will result in negative camber /---\

Raising an IRS vehicle above stock height results in positive camber \---/

You are correct. For some reason I mix that up about half the time. Maybe it's because I am left handed. I really do know which is which. Glad you noticed.

I love mine. I run them stiff (26 clicks front, 19 clicks rear) for drives, but for DD use I leave them on the softest settings. The rear is as low as I could go and then adjust the front a hair lower to keep the stock raked look. I only rubbed once during the drive to Bimmerfest on some heavy switchbacks.

I got them for $950 shipped on Amazon and they included rear adjusters.

This forum sucks for attaching pics, I give up.

All good! Sometimes there kids around so gotta make sure they get the right info - people believe everything
on the internet remember!!


Good feedback on the BC's. I had a set on my v35 skyline and they behaved like a much more expensive setup. No issues with reliability either. So long as they are valved correctly for the big X5 that's half the battle. The risk you run with companies like BC is that they make coil-overs for literally everything and I think a lot of the time they will adapt parameters from another car to save a redesign. Eg, they may make coils for a touareg, figure they roughly the same size and weight so just change the mounts to suit the x5. Sometimes they nail it (e39 M5 guys who track swear by BCs) sometimes they don't.
