Thank you for your letter. The changes to the spec line were made because the old spring parts are no longer available. The new
springs are readily available, affordable, and were requested by Mazda Motorsports. They are a stiffer spring than the old
allowance, thus the weight adjustment. Springs like these commonly cost a few hundred dollars. The old sway bar (yours) is the
basis for the measurements in the new spec line. New builds have the option to use a different set of bars. There is no change
to the shock rule, but Mazda Motorsports plans to offer a shock kit specific to the T4 RX-8. This option conforms to the T4 shock
rule that has been in place since for years.
