     Featured on BIMMERPOST.com

As Fall Line motorsports prepares for some major announcements during their 2015 race season, we at IND are proud to introduce the new F8x M3/M4 Fall Line Motorsports performance parts program. IND is proud to consider Fall Line a key partner in our ventures, having the pleasure of working with Fall Line for over 6 years to offer safety equipment, bespoke suspension components, and engine performance parts for IND’s Portfolio clients, we are proud to release a line of production parts specifically designed for the F8x M chassis.

One of the most exciting aspects of this project is the opportunity to look at the F8x M chassis cars in a wholesale systems approach. Fall Line’s racing experience, and their plans for the F8x M cars in motorsport enable IND and Fall Line staff to look at each area of the car as a complete system, knowing that an adjustment to one part will have an impact on the behavior of others. Although each part can be purchased separately, the parts presented by Fall Line will be designed to work together in harmony, for the best performing M3 and M4 possible.

The items now being built by Fall Line Motorsports will be a part of an ever-expanding parts catalog, which will continue to grow as Fall Line gears up to race the F8x M cars at the professional and club levels. What follows is a summary of our current efforts, with a basic description of each of the components Fall Line has created thus far. Expect a complete thread for each part in the near future, with more coming soon!

At present, we are proud to introduce the following components:



JRZ RS line of dampers





JRZ suspension was formed in 1994, and created around a need to innovate beyond standard damper technology. JRZ’s proprietary damper design focuses specifically on optimizing control of the vehicle’s unsprung mass. JRZ has found that their dampers result in reduced tire wear, increased mechanical grip, and overall better performance.

The Fall Line JRZ product line is custom tailored for Fall Line Motorsports specifically, and enables Fall Line to apply their analysis of the M4 directly to the suspension they create. The preparation for Fall Line’s 2015 racing program has enabled Fall Line and JRZ engineers to work together to create the best possible combination of damper valving, spring rate, and overall system design specifically tailored for the F8x M chassis cars.

Fall Line front mono ball kit



Fall Line’s mono ball spherical bearing conversion kit transforms the front steering and suspension feel of the M3/4. The factory rubber bushing is very large, and is prone to substantial deflection under load, as the M4 is put through its paces. Deflection of the bushing can create unwanted geometry change, steering wobble under braking, and even hysteresis of the thrust arm.

The Fall Line mono ball kit replaces the large rubber bushing found in the original thrust arm with a top quality spherical bearing by Aurora. The bearing’s housing is precision machine from aluminum, to create a rigid part that allows for the M4’s thrust arm to move smoothly through its range of suspension travel. The improvement in steering and suspension feel is immediate and truly enhances the
personality of the M4.

Fall Line race toe link kit





The race toe link kit by Fall Line Motorsports is designed to facilitate rapid adjustments of toe during an alignment, and combined with the tension strut will also enable adjustment of overall track. Not only does this allow for fine tuning of wheel fitment, these arms will allow an alignment shop to make quick work of car setup, even simplifying the camber adjustment process as a result.

A byproduct of multi-link suspension arrangements is a dynamic change in the car’s alignment settings- when making an adjustment to one attribute like camber, track width and toe will follow. This is especially true for the F8x cars, as the original BMW camber eccentric bolt has a major impact on toe as well. Alignments are made faster and simpler when using a set of aftermarket lower arms, enabling the alignment tech to easily reset toe after adjusting camber.

The race toe links utilize a unique clamp-style fastener system as seen in BMW’s own tie rods and Porsche Motorsport components, tightening the adjustment arm in place with no stretch of the hardware or change of alignment. Less expensive jam-nut designs limit precision and nearly guarantee an alignment change when the jam-nut is tightened. As will all Fall Line suspension components, high quality Aurora bearings are used to ensure a very long service life. ARP hardware is used throughout to guarantee the highest level of durability. Laser cut lockout washers correctly eliminate the original BMW adjustment, eliminating any unwanted movement in the system.

Fall Line Rear Upper control arm bearings



Rubber bushings found in the M4’s rear upper arms are the last weak link in an otherwise rigid suspension. The original BMW bushings yield to cornering forces applied to the suspension, resulting in camber and toe change that is not ideal for performance driving. Fall Line’s kit replaces the soft upper control arm bushings with military spec Aurora brand spherical bearings, enabling the rear suspension arms to move smoothly through their travel and giving the rear of a car a more solid, planted feel. The reduced geometry change allows for the car to retain its desired alignment, maintaining better control over the tire’s behavior under heavy load.

Fall Line tow strap



The Fall Line Motorsports tow strap is the highest quality strap available for BMW M cars. Fall Line combines 5 axis CNC machined stainless steel hardware with a CNC sewn strap for an extremely robust piece that will withstand the rigors of repeated use. The high strength webbing is available in an extensive selection of colors, and can be ordered in custom colors for no additional charge. Each strap is designed to thread perfectly into the M3/M4’s bumper reinforcement for an easy install.

Ummm. WOW. So so so cool. To be honest, I expected nothing less from the IND/Fall Line partnership though. Absolutely stunning.

Wow, those are so beautifully crafted pieces. +1 for IND making masterpieces. Any Fall-Line Engine/ ECU/ Body mods? Or is it strictly suspension/ drivetrain?

[MasterC17]

Nom, nom, nom. Awesome!

[JEllis]

OH LA LA

[Sal@AUTOcouture]

High end as expected

Thank you! We will develop components for the drivetrain and engine as well. There should be an excellent catalog of performance parts for the F8x in the near future!

[DieGrüneHölle]

So is Fall Line making the switch to the F82 platform for next years Continental Tire Series season?

[VMRWheels]

Wow, awesome goodies

[m5 guy]

So sick! Love seeing high end suspension solutions. Keep it up!

[Bob MG]

Yup no compromise for suspension set up components

RSS kit is what I used on my GT2, would be keen to try these fall line parts with my CS set up on the M4

What about adjustable drop links to allow for perfect corner weight set up?

[sroc]

Wow. Impressive.

[Fun of it]

Impressive, my shopping list just expanded.

[VCP]

Track duty!

[Diver]

Race car suspension, yeah!

Impressive, like the integration of the JRZ dampers.
Now this is one hell of a setup. Would like to know pricing for the whole kit, front and rear, including the springs and JRZ dampers as pictured? Send a PM if you have pricing, thanks

[Bosozoku]

Incredible parts. Glad to see some serious engineering being done to actually improve BMW dynamics.
Not just carbon fiber decorations and fart pipes for Metro showoffs.

[ilaurenzv]

Wow, awesome goodies

[Fidiman]

Only one word : impressive !

[vladberca]

These are some real performance upgrades!

Congrats to Fall Line for finally making the championship in GS happen. I know from talking with them at Autobahn during an SCCA weekend a couple years back it was a long hard fight and they should be commended for sticking with it, and against some really tough competitors with newer platforms.

Also, interesting BMW went with an aluminum rear upright on F8x, I didn't know that. That's a seriously impressive casting, especially considering the loads it's taking with all that torque and it doesn't look all that much more bulky than the cast iron one in the E9x M. Looks like they went with a bolt-in hub rear assembly instead of the press fit? Also appears the rear spring perch is further outboard for a better motion ratio than E9x
