SSM Stage 1 Plus is just the thing for those who want to go a step beyond just springs and bars or a great add on for otherwise stock cars who’d like to take the corners better but don’t want the stiff ride usually associated with performance handling. The secret is the combination of the extra tall ball joint and tubular Chrome Moly upper arms which greatly improves the camber curves and relocates the roll center. This means more grip and less body lean.

For drag racing our SSM Stage 1 Plus allows faster weight transfer and more positive caster for better top end stability.



The low-friction ball joints are legal for racing classes. Additionally, all low-friction ball joints have 32 degrees of swing angle for maximum suspension travel and contain no springs or plastic parts. Dust boots are not included but available at your local auto parts store. Dust boots can retain dirt and also hinder visual inspections.


SSM Stage 1 Plus works with your existing brakes, or any aftermarket disc brakes made for stock spindles.

Why Front end Geometry is Needed

If you want to improve the handling of your ride, you must first understand what is wrong with the original geometry. From the factory, these cars were designed to understeer. To make them do this, they used a very short spindle with the upper A-arm at a steep downward angle, which results in a backward camber curve making the tires lean out of a turn, using only the edges of the tire. Not only is this bad for mechanical grip, it's also why a stock B-Body tends to wear the outside edges of the front tires. Below is a diagram of the stock geometry at rest, and then in a hard turn. Notice the severe angle of the tires. All of the cornering forces are placed on a very small area of the tire.

To deal with this problem, there are several things that will help. Simply lowering the car will help to some extent, but not nearly enough to correct the whole problem. Bigger sway-bars will reduce the amount of bad camber gain, but again, it's not enough... it's like a band-aid on a gunshot wound.
To fix the bad geometry, you need a taller effective spindle height. The "effective height" of a spindle is from the pivot center of the upper balljoint to the pivot center of the lower balljoint. Tall spindles with stock balljoints, or stock spindles with extended balljoint studs will both achieve this goal. 
Below is a diagram of the same car equipped with a taller effective spindle height. Notice that the tires remain near vertical using the entire tread evenly across its contact patch. This is key to getting the most grip, and life out of your tires.
