tukaniSVT Interesting find about the springs. I didn't know that.

But then again, I haven't seen much suspension upgrades for the Focus that move the Spring over the shock in the rear.

fighing2succeed Thanks! I just got this confirmed on the scca forums also. Looks like getting custom spring perches and new springs and I'm good. I wish someone made rear spring perches for a 2.5" springs for the focus

wrc_fan If you go back to stock category allowances, sphereical bearings in the shock absorbers is allowed. Any changes allowed in stock are allowed in ST. Moving the spring position to be around the shock body looks like a no-go though.

Suspension rules for STF

I'm considering on buying coilovers for my Focus but have a couple questions. I'm under the impression from the rule book that you can't use a spherical bearing in the rear lower eyelet and that the spring can't be moved to run the coil over the shock???

The coilovers


The bearings



The rules

14.8 SUSPENSION
A. Ride height may only be altered by suspension adjustments, the
use of spacing blocks, leaf spring shackles, torsion bar levers, or
change or modification of springs or coil spring perches. This does
not allow the use of spacers that alter suspension geometry, such as
those between the hub carrier and lower suspension arm. Springs
must be of the same type as the original (e.g., coil, leaf, torsion bar,
etc.) and except as noted herein, must use the original spring attachment
points. This permits multiple springs, as long as they use the
original mount locations. Coil spring perches originally attached to
struts or shock absorber bodies may be changed or altered and their
position may be adjustable.
Spacers are allowed above or below
the spring. Coil springs may incorporate spring rubbers. Suspension
bump stops may be altered or removed.

B. Suspension bushings may be replaced with bushings of any materials
(except metal) as long as they fit in the original location. Offset
bushings may be used. In a replacement bushing, the amount of
metal relative to the amount of non-metallic material may not be increased.
This does not authorize a change in type of bushing (e.g.,
ball and socket replacing a cylindrical bushing)
or use of a bushing
with an angled hole whose direction differs from that of the original
bushing. If the Stock bushing accommodated multi-axis motion via
compliance of the component material(s), the replacement bushing
may not be changed to accommodate such motion via a change in
bushing type, for example to a spherical bearing or similar component
involving internal moving parts
. Pins or keys may be used to
prevent the rotation of alternate bushings but may serve no other
purpose than that of retaining the bushing in the desired position.

Are these coilovers legal for stf?
