THE GAME CHANGER STAGE II
These one-piece forged steel spindles are designed to work with GM A/F/X body cars.
BASICALLY BOLTING A C5 CORVETTE BEHIND YOUR WHEELS!!!
9-1/4" TALL spindles are engineered for lower ride height, improved negative camber gain and positive caster gain, plus more adjustable alignment.
They correspond with OEM parts and provide an overall 2" drop in ride height.
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 every stock Chevelle, S-10 or G Body wears 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.
TAKE YOU CAR TO THE NEXT LEVEL, THE Stage 3
THIS IS THE BEST MOD YOU CAN ACHIEVE IN HANDLING!!!
The stage 3 goes even a step beyond the AFX Tall Spindle and further corrects the terrible backward geometry of the factory front suspension.
The modular 3 piece 1/2" taller lower ball joints from QA1 further improve the camber curves and roll center location, significantly reducing lateral roll center migration for more predictable behavior. They also correct the factory bump steer issues by raising the tie rod ends into proper alignment. We build these for you before we ship.
To achieve near zero bump the front end must be designed correctly. The tie rod must travel on the same arc as the lower control arm when the car goes through travel. The stock chassis does not do this!
WE FIX THIS!
Now with extremely improved geometry designed for the rigors of SCCA, TransAm and NASCAR your car will truly dominate the street and track!
