[quote=08FitSport;410143]13.5 SHOCK ABSORBERS
3. Adjustable spring perches are allowed, but the spring load-
bearing surface must be in the same location relative to the
shock mounting points as on the standard part. Shims may
be used to achieve compliance.
4. The fully extended length must be within plus or minus one
inch of the dimension of the standard part.

Are you sure? It sure looks like it's allowable. The Fit so called "coilovers are same design as stock (no additional parts or coil over the rears the front is struts so coil is always over) It also states adjustable perches allowed.

What does the spring section say?
And I'd look real close at rule 3.
Generally speaking alternate shocks used to be OK but not if they altered ride height. Coil-overs can do that because they have an extra part: the spring perch is adjustable in distance from the shock mounting points. As soon as you change ride height its no longer stock but you can use coil-overs if the spring perch is same as stock.. If you use coil-overs the spring perch must be located same as in stock position. The 2 external adjustments refere specically to dampening rates, not any kind of adjustment. Thats amed at Konis.
That brings us to the question of what springs are allowed.
And what is rule on ride height? (in the old days we used to grind the upper half of the upper coil seat wire diameter and the ower half of the lower coil seat wire diameter to get tha little advantage. Some went so far as getting new springs made to customize the roll caracteristics with stock ride height) Those were good for both A/X and SS. Haven't even touched on changing shock fluids yet, always a goodinterpretation of the rules..
