*Important* You must let us know what control arms you are planning to use and color preference, grey or purple, in the notes when you order, otherwise your order will be delayed until we obtain that information. 

While it may be quite affordable, this kit packs a powerful punch for both racers and drifters by offering most of the same benefits of our proven full front-end kits, while using an OEM control arm.  This is great for classes that do not allow aftermarket control arms, and if you decide later to upgrade to SLR tubular arms, you’ll have a set of spherical-jointed OEM arms that you can sell or keep for spares.

This kit replaces your original outer balljoint with a teflon lined spherical bearing and uses the SLR steering plate to correct roll-center by 35mm while adjusting the bump-steer to match as well as offering the ability to fine-tune both.  It will also quicken your steering ratio by 40%* (or 28-30% reduction in lock-to-lock depending on chassis), removing the need for expensive custom quick-steer racks.

Can be configured for race, autocross, or drift use via patent-pending SLR adjustable ackerman system.

The chassis selection is based on which steering knuckle (Hubs for our UK friends) you are using on your car. If you are using E36 knuckles on your E30 then order the E36 kit and so forth. Race or Drift selection is simply which end of the ackerman adjustment you would like your steering plates to be pre-configured out of the box. This can be changed at anytime after you have received your kit. Lollipop selection is based on which control arm you are using with your kit. Factory E30/E36 and SLR Chromoly control arms use the round insert on the adjustable Lollipops, factory E46 arms use the hex insert.

Note the Delrin standard Lollipop bushings will not work with factory E46 control arms as standard. The rear pivot must be rounded down to fit.

Control arm ball-joint removal and bearing installation instructions are included

* Steering quickening determined by 40% more actual front wheel angle in the first turn of lock.  Though it may seem a large increase in steering ratio, many customers still combine the kit with a Z3 rack for ultra-fast steering.

EXCELLENT choice for the money!!!
Color: White, Number of Items: 1
I have never written a chair review, however; I feel this product warrants it. I got this chair to replace an old chair in my studio. I scoured Amazon for hours to find it, and I am glad that I took the time to do so! I was worried about material quality and durability at this price point, but my expectations were FAR exceeded. The piece goes together with a quickness (for me, under 10 minutes), and I only glanced at the instructions once. Suffice to say, setup is simple and intuitive. Once the chair is together, there is a slight amount of play where the base plate attaches to the shaft, however it isn't a ridiculous amount. I only noticed as I was examining it and being critical after my initial excitement. The materials used are very good, and much better than you would likely get from other chairs at this price. The chrome finish is nice, and the chair PU is uniform color with no defects. One really nice feature are the zippered arm rest covers; when they get dirty, which (being white) they eventually will, you can unzip them, lay them flat, and clean them laid out, as opposed to struggling to scrub around 90 degree angles. I am sure this was easier for the manufacturer, but the end result helps the end user as well. Good on them for that. Another thing I am very happy with is the height; I am 6'4" in bare feet, and my wife is 5'0". We both fit comfortably after adjusting. They definitely got the seat height right. And to that point (of size), at my height, and 260 pounds, there is plenty of room at the sides. Mind you, however, I am fit. That is not to say that a 5'10" guy that is 260 will find it comfortable. He may not. That said, most people should fit in this without an issue. The casters had a positive snapping-in, and roll over my low carpet easily. This chair is definitely well built, save for the slight play mentioned earlier. In no way does that detract from it at all. The aesthetic fits my studio perfectly, and in all, I would not hesitate to recommend this chair. If I have any issues with it, I will post an update review, but so far so good. I really love it. If you like the way it looks, pull the trigger. It is definitely worth the price, and more.

A great choice at affordable price

The design of the chair is sleek and nice looking at a very affordable price and a decent quality. It is the cheaper version of a more expensive one. The wheels move easily; the back of the chair tilts just enough; it is a deep chair to support my back (only 5"3), so I added a back pillow making perfectly comfortable to provide support needed for long period of times. If I have a negative comment, it is about the back of the chair being black so purely matter of esthetic.: and armrests narrower than I'd like and wrapped with 2 pieces of leather connected with a piece of fabric a bit loose with a zipper which will allow overtime to be completely removed and left with chrome completely if wearing out or simply if you prefer that look so options. A great purchase

Great looking chair, a bit hard, fantastic value!
Color: White, Number of Items: 1, Color: White, Number of Items: 1
3 for comfort, 5+ for looks and 5 for ease of putting together so I landed on a 4+. I absolutely love the way this chair looks and it accents my other darker office items well. I'm 5'4" and can sit in the chair, all the way back without a pillow so the size works well for me. The back support is fine and you can adjust it if you want it straighter or rock back & forth. I changed out the casters for a more rollerblade type wheel when so I can't speak to the rollability of the included casters, but works well with the wheels I installed. Fantastic value and I'm soo glad I purchased it!

Unbelievable!!!

First off, let me say wow! When I received this, I didn’t expect much because of the price, but I am blown away with the care that was given in the packaging alone, the simplicity of putting it together with the detailed yet brief instruction page, and the ability to put this together with one person. Took me less than 40mins. Highly recommend!!! And in fact, I’m purchasing another one right now as I’m sitting here rocking in my new beautiful chair. UPDATE: a lot of negative reviews are basically user error. To attach the wheels, to snap on, I used a rubber (not metal) mallet to tap them in. To the leveling review, you have one arm on backwards. To the screw passing through, you may be correct but double check you didn’t use the required screws elsewhere. And the person saying it doesn’t recline, you have to release the lock - pull the up and down lever out and away from the seat. Good luck all! Bought a second one - same thoughts as above. Pretty awesome chair.
