Hi guys,
You may or may not have heard that a new part is available for the 25 year old Miata. The Extended Lower Ball Joints are forged bits that allow for more negative camber in front by pushing the bottom of the hub out just a bit. At stock ride height, the range is about -.5 to -3.5, with higher negative camber than those numbers available at lower than stock ride heights. The benefits for SM are obvious, and include getting ideal negative camber AND max caster, hitting your negative camber and even being able to raise the ride height a bit, and using a part that costs less than the OEM equivalent.
NASA has approved these for use in Spec Miata, Super Miata, and they're also looking at them in the autocross classes, although those classes are getting a thorough review so the jury is still out.
SCCA is still looking at the option of using the ELBJ's, and we're hoping that input from the racers will help with the decision. Hence the poll.
Please give us your opinion on the poll and let us send the information to SCCA prior to their next rules meeting on January 5th. These parts are being sold by Flyin' Miata, V8 Roadsters, 949 Racing, Goodwin Racing, Miata Roadster and the supplier, Bauer Limited Production, maker of the Catfish.
