Suspension:

OP 1113S Sports Spring Set: We have two brands of progressive rate sports springs for your chassis. These fit the car with no other mods, but we recommend that you use our shorter sports gas struts for the best combination of handling and ride quality. Available in 1 1/2" and 2" drop from stock ride height.

OP 1212U Upper Front Strut Tower Brace: This tubular brace ties both strut towers and the firewall together to eliminate flex in the front upper unibody during hard cornering. It improves steering feel and consistency, but does not control body roll. (See swaybars <anti-roll bars> listed in this section) some drilling required.

OP 1212L Lower Front Subframe Brace: Triangulated ends with low profile tubular cross brace ties the front lower suspension subframe together to eliminate lower a-arm flex during hard cornering. This gives a much more consistent feel and stability to the suspension under hard cornering. Some drilling required.

OP 1213 Rear Strut Tower Brace: This braces across the rear upper shock towers to increase the rigidity of the rear unibody for more precise handling. Easy bolt-in requires no drilling. Does not fit the convertible chassis.

OP 1181BK Front Swaybar Urethane Bushing Kit: This kit includes both new end link hardware with urethane grommets and new subframe bushings with greaseable fitting. This gives you a tighter front bar action. Bushings available for different size bars, also.

OP 1181 26mm Sports/Competition Front Swaybar: This is a substantially bigger front swaybar for serious handling improvements. This bar should not be used on a street car unless a larger rear bar has already been installed. Best when used with lowered stiffer springs for competition use with a 26mm rear swaybar also. Comes complete with urethane links, and greaseable subframe bushings.

OP 1192 22mm Rear Sports Rear Swaybar: This is a nice handling improvement for your car which should be done after you have good struts and springs. It makes the car handling more neutral and gives less body roll. Complete bolt-on kit with grade 5 hardware and urethane bushings for more precise control.

OP 1200 26mm Rear Competition Swaybar: This is the optimum rear bar for the more modified cars. Can be used on street cars for autocross where you want more oversteer (rear end to come around more) but it should be combined with a bigger front bar to balance out handling for street use. All urethane bushings too.

OP 1208 Rear Susp. K-Brace: Eliminates suspension geometry changes during hard cornering and straight line acceleration. A must for the serious autocrosser or drag racer. Does not clear certain rear swaybars, so inquire before ordering. Bolt-on design requires no drilling.

OP 1833SX Power Slot/Cross Drilled Rotors: These rotors are engineered to take advantage of both slotting and cross drilling with no loss of rotor integrity. Come with carbon metallic pads for much improved stopping power and less brake wear.
