Couldn't load pickup availability
Intended for 1982 to 2006 BMW 3 Series *For E46 M3 see separate listing*
Please note, our race kits do not add steering angle, and often will reduce steering clearance slightly because they are designed with a delta shape in place of the L-shape factory arms to provide a stronger arm with direct load paths for minimum weight.
Lightweight tubular high strength control arm set, including matched Billet 7075-T6 Aluminum roll-center, bump-steer and quick steering geometry plates. Each control arm is 100% TIG welded in house by a master of the craft. Built to OEM control arm length by default. These are some of the lightest and strongest front control arms available on the market. If you have a little extra room under the fenders, instead of adding spacers or low offset wheels we can build the arms to suit +54mm or +108mm Track width in order to increase your track while maintaining your scrub radius as close to stock as possible for better, more neutral steering feel and control. Unlike our drift kits we do not build the race kit with maximum angle clearance in mind, this kit is built with the sole purpose of lowering your lap times.
No sway bar provision by default as we recommend the M3 style strut sway link, but a control arm sway link provision can be added as an option if requested.
The arms are affixed with custom designed and developed hardware proudly machined in the USA by SLRspeed from forged 4140 billet steel.
This kit bundles four expensive upgrades for your car into one affordable package:
- Lightweight chromoly control arms(40% arm weight reduction for e30/e36)
- Roll-center correction
- Bump-steer correction
- Quick-ratio steering
Compare to other companies that charge nearly as much for simply a pair of control arms and hardware that you will need to purchase additional parts to get the same -benefits as our complete package.
Please contact us about custom widths beyond our online catalog listed here 561-485-9997
**PLEASE NOTE** All E36 race arms are built to 93-95 M3 geometry unless otherwise requested, (96+ Evo 3.2L geometry can be built, but has less clearance for larger tires) additional caster can be gained by using our adjustable lollipop (FCAB) as well as caster top mounts.

* Steering quickening determined by 40% more actual front wheel angle per mm of lock. Or in other words, instead of the front wheels turning 10° in the first half-turn of the steering, they will now turn 14°. Many customers still combine the kit with a Z3 rack for ultra-fast steering.

Let customers speak for us
Brian R. was extremely helpful and spent a good amount of time answering my questions about switching to coilovers. He was a wealth of knowledge and made the purchasing and installation process very easy.
He is so genuine, he helped me out on which parts I should get for my wife’s ‘16 Veloster Turbo. Parts came super fast and was packaged beautifully
Havn't installed yet so I cannot speak to the parts, as they get some run time I will review. Brian at FI was amesome though all through the process. Had questions prior to ordering and he went above and beyond in providing me with answers. After I ordered the parts he called a few days later appologizing for not reaching out sooner, which is crazy cool since country was dealing with hurricane devestation. I didnt expect to recieve parts for a while however they all showed up in about a week. I will def do buisiness with them again and recommend them to anyone in the future.
I bought Silvers Neomax coilovers with aero spring rates (14k/12k) for my track car. The quality of them is great. Install was straight forward and they are easy to adjust and tune as needed. Real happy with them so far and I think they're the best value out there in coilovers. Great price without a sacrifice in quality or performance. Also Brian at FI PERFORMANCE has been great in responding to all of my questions. Has been a great experience so far.
Quality part.
Brian answered every time I called and answered all the questions
Excellent coilovers
The best customer service from Brian
Highly recommended
Car looks great and. Handles amazing
Works great it stiffens up the rear end and no more wheel hop best diff brace out of all I have used in the past, money well spent.
Installed the After Dark hooks on my C5: the rear hook was very easy, and if you only need one hook, it's a quick and easy install. Front is more work: you're going to want a step drill or right angle adapter, since clearance between the bumper and A/C condenser is tight. Drilling into the bumper is not trivial: it's hard, use cutting fluid and make sure your drill bits are sharp. Once it's drilled and the rivnuts are installed, it's easy from there. It's a good design, well made, and at a reasonable price.
The product was originally marked for 2005 and up gx470. I managed to fit it into my 2003 by flipping one of the front hanger mounts. Sound is throaty and deep a bit loud at first. But the sound has mellowed out after a few hundred miles. Hardest part was removing old exhaust had to use Sawzall. Make sure to buy the 2.5 donut gasket ahead of time. The system is high clearance. Its tucked between the frames no chance of hang ups.
It’s the best mod I’ve done. Should have been the first thing I did.
Brian was extremely kind and helpful to make sure I was getting set up with the correct products. The Brey Krause harness bar is extremely high quality. Don’t cheap out on safety stuff this is definitely the harness bar you want in your c5. The combination of great service from Brian and the quick arrival I highly recommend FI Performance and will definitely be using them in the future!
Five stars for the parts and service. Ride quality is better than expected for a coilover setup. And Brian was super helpful in getting the correct setup for my truck
Fits perfectly and does exactly what it needs to do. No complaints.
Brian recommended these end links after sharing my plans to do some HPDE, Autocross and Street driving for the C5 Z06. The parts feel great, I did have a warranty issue that was addressed by both Brian and AFE, I was very satisfied that they took care of my issue in a timely manner as well. Highly recommend both Brian and AFE, thank you as always for your help!
