The FD has a surprising amount of factory bump steer.\u003cbr\u003e\u003cbr\u003eWe were pretty amazed when Ronin proved this in testing. Check out the \u003ca href=\"https:\/\/youtu.be\/tN4JNP2yN6c\"\u003evideo\u003c\/a\u003e if you haven't seen it yet. It really debunks the notion of any \"magic\" in the FD's steering rack placement. But it also got us thinking: where do folks actually want to set their kits? Do they prefer a racecar-perfect setup, or do they enjoy the lively, if less stable, handling that Mazda originally designed?\u003cbr\u003e\u003cbr\u003eIt's such a personal preference that, for now, we've decided to give you full control. Our kit for Ronin (or Samberg) subframes includes options to shim the steering rack—aim for about 1\/8 to 3\/16\" clearance from your oil pan—and adjustable Speedway Motors spindles.\u003cbr\u003e\u003cbr\u003eBut here's the twist. One issue with adjusting bump steer by lowering the ball joint (using rod end sphericals) is that it can stress the spindles. And those Speedway spindles are pretty long. Many RX7 owners end up cutting them down, but some have still managed to bend them, especially during spirited driving.\u003cbr\u003e\u003cbr\u003eTo address this, we're throwing in a little something extra: a Ronin exclusive support piece. This nifty contraption slides over the spindle hex and is tightened just snug—don't overdo it! It provides a wider base of support for the bending load as it enters the steering knuckle. Just be careful not to pinch the rod end against the spindle support nut!\u003cbr\u003e\u003cbr\u003eAnd if your rod end is already high enough on the spindle that the support doesn't fit, don't worry too much. The added bending force is likely small enough that you won't need it anyway.\u003cbr\u003e\u003cbr\u003eOur full bump steer kit for Ronin or Samberg subframes includes everything you need:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e2x billet machined steering rack interface pieces\u003c\/li\u003e\n\u003cli\u003e8x steering rack spacers (each 1\/8” thick, so you can adjust up to ½” rack motion)\u003c\/li\u003e\n\u003cli\u003e2x Mazda tie rods to rod end adapter pieces (precision machined from high-strength stainless steel)\u003c\/li\u003e\n\u003cli\u003e2x Aurora rod ends (because we only use top-quality bearings)\u003c\/li\u003e\n\u003cli\u003e2x Speedway Motors “pinto” steering rack spindles (complete with nut and lock nut to locate the rod end)\u003c\/li\u003e\n\u003cli\u003e2x Ronin spindle supports with 2x locking jam nuts.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003eSo, how do you go about adjusting bump steer?
