IND F80 M3 / F82 M4 wheel fitment compilation thread

BIMMERPOST
     Featured on BIMMERPOST.com





IND Distribution has been dedicated to the BMW M car since the companys inception, and through nearly a decade of commitment have done everything possible to learn the secrets of BMW M to a science. We have explored every aspect of BMWs marvelously engineered machines, and work tirelessly to ensure that our client base is always at the forefront of available information.

Today, we are proud to announce that in cooperation with BBS North America and Falken Tire we have made the first critical steps to understanding the M3/M4s wheel well packaging, and in turn the available space we can use to install wider wheels and tires.

While IND specializes in custom tailoring widths and offsets specifically to the client, this document will provide some good basic guidelines for what we've found works, and what does not. IND will work directly with BBS to develop custom width and offset wheels for the M3 and M4 in the near future, so please keep in mind that what you see here were existing applications and installed on the F80 for testing purposes only.

For those who have not been introduced to the BBS brand, please have a look at our photo tour of both the main German BBS manufacturing facility, as well as the more elusive tour of the German headquarters of BBS Motorsport:

http://www.m3post.com/forums/showthread.php?t=917761

http://www.m3post.com/forums/showthread.php?t=914945

BBS has been responsible for creating some of the best road and racing wheels in the world, and have contributed more to the modern racing wheel than any other wheel manufacturer. We can think of no better company to partner with, for this or any other project.


With all of this said, we are happy to present our findings to the M3/M4 community!


Late last night, one of the first F80 M3s in our area rumbled its way into our warehouse for the first ever test fit of performance wheels on this chassis. After several hours of measuring wheel well clearance, damper position, and the shape and packaging of the cars brake system, we were finally ready to move on to the good stuff- actually test fitting wheels!

A few basic cliff notes are in order, before we get into the details of our findings:
  • Please keep in mind that IND custom tailors each set of wheels we sell to each client we have, and that the information below should serve only as basic guide lines.
  • We're happy to say that the OE brakes easily clear 18", 19", and of course 20" wheels. This car should accept a wide range of wheels and tires both for the track and the street!
  • We're also happy to announce that this car can easily accept very wide wheels! Thus far we've focused on 9.5" wide front wheels, and 10.5" wide rear wheels.
  • We've found that a 9.5" wide front wheel with a +27 offset, and a 10.5" wide rear wheel with a +35 offset will be very flush fitment on the F80 chassis, giving the car an aggressive stance for a good basic setup.
  • We've also determined that a 275/30/19 front tire and 295/30/19 rear tire are a small 2% smaller in rolling diameter than the tires originally provided by BMW, and are a great fit and sizing combination for both appearance and performance.

The M3, with IND's custom painted engine cover.



Installing our Macht Schnell stud conversion kit.



Measuring maximum caliper diameter.



Our test subjects for the night.



The BBS RE wheels, mounted on our client's F80 M3. These were a good fit in front when spaced to a +27 offset, and just a touch too flush in the rear, at a +30 offset.



Wheel fitment close ups of the BBS RE wheels. You can see that the 9.5" wide wheel works perfectly with a +27 offset, but the 10.5" wide wheel should be just a touch higher offset for a great fit.






The BBS FI wheels. At a 9.5" front width with a +26 offset, the front FI fit nearly perfectly. The 10.5" +28 rear wheel was too aggressive.


Front brake clearance shots of the 19" BBS CH-R wheels. Plenty of space!


Front and rear brake clearance shot of the 18" BBS FI wheels, again showing available space.





We will continue to update this thread as we learn more about these amazing new machines. All of us at IND are absolutely thrilled to begin to study, analyze, and develop the M3 and M4 to their fullest potential.

Ilia, by how much was the 20" FI too agressive? Did it poke?
Since a 10,5 ET 35 would be perfect, I can't really imagine those 7mm being that big of an issue?

Will the front 9.5 wheels with +22 offset be okay?
I ordered 9.5 +22 front and +35 10.5 rear.
Still didn't decide about the tire size. The CUP2 doesn't have the 275/30 size, so if I go with 295/30 rear wheat should I install at the front? Will thw 265?35 be okay? Or I'd better use the stock wheel size?

Tnx.

A little off topic, but what is the purpose of that bent up thin metal piece behind the rotor? It's a huge eye sore on the standard brake.

It's a splash shield, found on nearly every passenger car on the road.

Contaminants splashed on the inboard brake plate of the disc are a source of brake roughness, which drives warranty claims for the manufacturer. The presence of the shield helps this a lot.

Of course it's not what you want for heat dissipation, but these are road cars first and track cars second.

The LM-R wheels we had on hand were not sized appropriately for the F80, but we have another F80 coming on Friday. I will install the LM-R wheel and at least take a side shot so we can all admire them on the F80!

BBS FI wheels are currently built in one offset in the 19" BMW application, but we are working directly with BBS now to create offsets specific to the F80 and F82 chassis cars. The current FI offsets are too aggressive, so we will work hard to create the appropriately sized wheels as soon as we can!

Thank you for your kind words! We are so excited about the new cars, I just feel privileged to be able to dive in and learn about them.

I believe that with a smaller tire, the 20" FI could have worked, but our 295/30 tire did require a higher offset wheel. The FI poked by about 7-8mm with the 295 installed.

Thanks! I stopped in my tracks also when I saw the FIs installed on the car.

The +22 offset will be aggressive, but will work. We had the RE spaced to a +27 and still had some mm to go before the wheels were too flush. You should be in good shape. I'll respond back to your tire questions in the other thread. Also don't hesitate to PM me with any questions!

As stated by Floridagator, those are splash shields- not needed on a track car, but important for BMW as an OE manufacturer.

Agreed, I will never grow tired of LMs. I'll find a set to test fit ASAP!

Thanks for posting this. Dang, it looks like my 19" Forgeline GA1Rs might be too aggressive with the 275/30r19 / 295/30r19 AD08Rs. (I have 19x10 et 25/19x11 et31)

Tnx a lot! May be the way to go is to add 5mm spacers to the rear to have the proper look and I hope, that with the stock front tire sizes it will be okay!

PS Ilia is a russian name - r u russian?)

How will the wheel fitment be when it's lowered, will the wheels camper in like on the f10?

I have a set of TE37s on my E90 M3 19x9.5 +22, 19x10.5 +22

Ilia, from what you posted, my fronts are probably ok and the rears are not if I were to use them on an M4?
