"T2-T4 5: A maximum of 3.5 degrees of negative chamber is allowed on front and rear suspensions. Spec line part(s) may not be
modified to increase caster and camber. Strut suspensions may adjust camber and caster by the use of eccentric bushings,
eccentric bolts (crash bolts) at the strut-to-spindle, and/or by use of slotted adjustment plates at the top of the strut mounting
plate. If upper strut slotted adjustment plates are used, they shall be located on existing chassis structure, utilizing the
unmodified manufacturer’s original bolt holes and may not serve as reinforcement for that structure. Slotted adjustment plates
(strut camber plates) may incorporate a single spherical bearing (spherical bushing) and a ball thrust bearing per strut tower. On
other forms of suspension, camber and caster adjustment may be achieved by the use of shims and/or eccentric bushings.
Adjustable toe links with spherical bearings are permitted and may serve no purpose other than adjusting toe angle. Spherical
bearings/bushings are not permitted in T2-T4 5 except for the specific examples listed in the class rules or vehicle spec line."
