the most recent fastrack has a new proposal for Stock class that would allow either a front or rear sway bar upgrade (but not both)- the current rule set (which goes back several decades evidently) only allows for a front sway bar change.
I wrote in support of this proposal as it takes away the argument that car x benefits more from a front sway bar change than car y. The rule was written originally as almost all cars were RWD, obviously things have changed with a large number of FWD and AWD competing anymore. It's possible a front sway bar may still be more beneficial than a rear for many cars (regardless of the type of drive), but this leaves the decision to the contestant to make
if you care to comment on this proposal (or any other) they have gone to a new format (no longer accepting emails) where you submit comments on this online form
