NOT JUST STEERING ANGLE...

The SLR Complete angle kit completely transforms the response, handling and overall ability of your car in ALL performance driving situations!  Many knuckle and lock kit packages out there will add some angle, but we address the complete front end with a comprehensive approach, starting where it matters most: ROLL-CENTER

By fixing roll-center your car will resist body-roll naturally through proper geometry and actually create a better turn-in response, smoother better handling, and even more stable braking, especially in transition driving.

The SLR geometry correction also creates a more effective camber curve and enhances feel throughout the steering and suspension travel range.  Remember, this is all just the first part of how our kit gives you the competitive advantage.  After that, we quicken the steering ratio, saving you $600+ for a quick-steer rally rack, and to finish the package, there's built in bump-steer correction which again saves you $$$ from piecing together several components from other vendors.

Designed and built in the USA for BMW 3-Series and BMW Z-cars. This kit increases track width (hub-to-hub) with professionally TIG welded 100% Chromoly control arms for an unmatched combination of light weight & extreme strength. SLR steering plates are made from ultra high strength alloy with 35mm of geometry correction and industry-first Ackerman adjustment (4 positions), in an easy to install, lightweight, completely bolt on package. 

Made from high quality chromoly steel hand welded here in Florida. Beware of imitation arms and fake suppliers of SLR selling arms made from normal mild steel. We get calls every week of people needing fake arms and parts replaced since they bent or cracked - save yourself the headache and don't get scammed!

SLR strives to create the highest quality steering kit on the market at any price.

Kit Features

  • up to 70°+ of steering lock (depending on wheel/tire combination)
  • 40% faster steering ratio
  • Only 3.1 turns lock-to-lock at 65°!* PLEASE NOTE: 93-95 M3 rack limits angle, we      recommend swapping any 96+ base E36 or E46 rack
  • 35mm roll-center correction
  • Matching bump-steer correction
  • Four position adjustable Ackerman to suit track and/or driving style
  • Sway bar bracket to fit E30/E36 type Swaybar links (can retrofit on E46 also please contact us for more information) 
  • Legal for all drifting series worldwide (including Formula-D & USA pro-am)

Options

  • Chassis: Please Choose which Chassis the kit is going on, If you are using E46 M3 knuckles on a different chassis please let us know in the notes.
  • E30&E36: The super kit will widen your E30/E36 by approximately 11cm  and the Ultra kit will widen track by 16.5cm  The Super angle kit is a more street-friendly kit that doesn't absolutely require flares, or widebody.  You can even get away with rolling and pulliung the factory fenders if you run something like a +30 offset and a 215 front tire.   If you want to absolutely maximize angle with 18inch or larger wheels, go for the Ultra kit instead
  • E46: For E46 cars the Super kit will widen the front track by 5.5cm, and Ultra will widen it by 11cm.    E46 cars can easily get away with running a Super kit under stock fenders, but again to maximize angle with an 18inch wheel, go for the Ultra kit.
  • Lollipop (FCAB) Choose "None" If you are happy with your current bushings. Choose "Delrin" for our milled centered Delrin lollipop bushings if you want to just upgrade your stock rubber to much more solid Delrin (All E46 and Z4 will come with Delrin Bushings by Default). 
    Choose "Billet Adjustable" to include our caster adjustable Billet aluminum Lollipops and hardware.
  • Colors:  Gunmetal Grey  or  Violet Purple .   Custom colors available by special request (additional charge and longer delivery times apply)

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.

Super cute, comfortable, practical, love that they are slip on
Size: 10.5, Color: Tobacco/Black
I have worn these 2-3 times already. The first day was a school/work day so I was on my feet 9 hours and the only issue I had was with the side of the boot rubbing against my ankle. I just make sure I wear socks high enough to cover my ankles or jeans that go into the boots now for long wear days. Absolutely love them! They keep my feet dry in this snow( we live in Michigan). I had been looking for a pair like this for awhile now and was getting super frustrated that I couldn't find my size in any that I liked. I saw that they had these available in a 10.5 and I wear 11. I looked at the Sorel website reviews (since the amazon ones weren't super helpful on sizing) and they said that the boots ran big so I took a chance on the 10.5 fitting me. They fit perfect. I have long narrow feet but I could see where they would be tight or uncomfortable on someone with wider feet. I've been trying to find a pair for my mom now since she has boot envy.
