My '07 650i with 21" Alpina B7 Slippers

Hey guys,
I finally had a chance to take a few pics of the new wheels on my car. These are off the newest version of the B7.
They're 21x10's (41 offset) with 295/25/21 in the back and
21x8.5's (25mm offset) with 255/30/21 in the front. I have 18mm spacers in the back and 15mm spacers in the front from Burger Tuning. The TPMSensors came from Tirerack (great deal and same brand BMW uses) and I only needed the actual sensors because the wheels have the valve stems and holders built into the actual rim. The car is lowered with H&R springs and there is no rub!! Fronts turn free no problem and the ride is super smooth. Just a little paranoid now about potholes and ditch-like sewer caps...


I found it very difficult to find sound advice from any wheel/tire guys up here as to whether these would fit, etc. If they sense they can't make money off of you then all of a sudden they don't know what wheels and tires are. So checkout www.willtheyfit.com. Major lifesaver! You type in all the stats for your current wheels, offsets, and tires and also the new proposed setup and it will show you everything you would need to know to determine whether they will fit.


Decided to try out one of the DIY Air Scoops to compliment the AFE Intake. Fairly easy, the mounting was a little bit wacky but managed to get it fitted after a bunch of test fitting and trimming and beer breaks as well as dedicated swear word breaks. But it is much more satisfying making it yourself then paying RPI a $100. The sound is unreal from the intake, and combined with the full resonator delete with x-pipe, there is no need for muffler upgrades. Sounds insane.

Anywho, thought I would share my latest stuff.
Take care

Love those wheels, they look awesome. I think 21" is the perfect wheel size on the 6er.

nice wheels and i thing so too 21" is best looking on 6er

You did some geat mods CTCK650. Very tastefully done. The Alpina rims are great rims. Had a set once but got tired of the cleaning that is required, especially between the vanes. But they are beautiful rims when spotless. I love the way they sit on your ride.
Nice DYI on the scoops too. It's great when you can do these things for yourself.

Haha, I have a buddy with rims like that and says they are a bear to clean, that was my second thought! The first thought was how great that his car looks.

I have my air scoops done by myself and free....i will post some pics...i love doing things by myself for my car....

Thanks boys, I think 21's are the best too. My car wash time has increased by 15min making sure the wheels are completely clean haha. That's ok though. It's worth it!

When your pads wear out I would go for some super low dusting pads like Akebono or if you are a performance nut StopTech Street Performance pads which are almost dust free but stop as well as OEM.

Great idea Yorgi. I'll check out those pads cause it's getting a little ridiculous haha

Nice 21s look perfect

Do you have any challenges with the wheel wells .

Looks amazing!! Apparently 21's are perfect for the 6.

Damn it looks good, if the roads were better here in the UK I would get a set of them, does anyone know if they are available in the UK?

Also I heard rumours that if you have larger rims it puts strain on the steering rack, is this true?

Brilliant, just what I was looking for!

I also have the hr springs and have just bought 21" schnitzers with the same tyre setup.

Was wondering what they would like at the ride height setup, I think it looks perfect

Hey what's up Tinoxx, what front lip do you have on your ride?

Alpina is German so you should have a much easier time finding B7 wheels over in the UK, I would guess there are a lot more Alpina cars rolling around in the UK compared to North America.

Larger wheels are usually heaver which puts more load on all the suspension components. Things like like endlinks, struts, ball joints and bushings will wear out slightly quicker. Wider tires give you more grip which in turn can lead to more stress on the suspension in general. It's not a big deal though, I would not worry about it.

Hi Prospect500

It is a CSR I bought from them direct, and it was a perfect fit. I feel it makes a big difference. Not finish yet. Once body is finished then the interior.

Thank Yorgi as always

Where did you get the front lip?

I ordered the lip from www.schmiedmann.com. It's cheaper than EBay and will be shipped to you directly from Alpina.

As nice as those rims look in the pics.....the pics do NO justice to them. thoses rims are beautiful in person. I have 245/295 21" on my 6 with eibachs and it's perfect. IMO 21's are the way to go on the 6.....I also endorse the Akebono pads....i have them and the result is ZERO brake dust and the stopping power is just fine IMO..

Congrats
