Big brakes have been a big deal in rock crawling and rock racing. We’ve been manufacturing 14″ diameter rotors since the early rock crawling days, and the extra stopping power at lower speeds has become an easy must-have. That being said, in today’s Ultra4 vehicles, especially those newer IFS powered versions, the large 14″ diameter rotor is a bit tight. Factor in mud and debris from those east cost races and clearance between the caliper and wheel can be an issue.

As such, the need for a slightly smaller rotor is born. Enter our prototype 13.5″ diameter rotor, which starts as Wilwood GT-36 Vented Rotor, precision machined down from 14″ to 13.5″. Brake hats, calipers, and pads all work as-is. The caliper pad also has full rotor contact, so no compromises either.

We’re giving these a test now, and so far so good; the extra caliper clearance for those that need it is obvious and welcome, and this rotor should do the trick. Stay tuned for more details.

As drivers continue to push the boundaries of what’s possible, our Spider 9 products evolve to push those boundaries even further. We’re proud to release our latest Ultimate Knuckle, designed ground up to surpass the strength of our previous generation Pro Series Knuckle. Complete with 7/8″ spherical bearings, internal gussets, interlocking steering arm, and industry leading 50 degrees of steering, there are simply no shortcuts here. Take rock crawling and rock racing to new levels with the Spidertrax Ultimate Knuckle, now available on the Spidertrax Store.

There are only two holidays that come to mind when we’re granted a few days off in a row. That’s King of the Hammers and Christmas, and wouldn’t you know it’s already that time of year. We’re talking Christmas of course, although KOH will be here before you know it!

Our phones will be off all next week, that’s December 25th thru December 29th January 1st. During this time, we’ll still be shipping online orders (and those orders submitted by fax or email) and responding to online support cases, except for December 25th & January 1st where we’ll all be off here.

With that, have a great Christmas and a happy holiday, enjoy a little time off with friends and family!
