I thought the chassis needed new holes to accomodate the Suspension brackets. Drilling holes in the sway bar still doesn't register sure you guys will be patient with me. I'll eventually find out where the sway bar had holes to start with other than at the wheel bushings.
The improvements are to help increase the stock bar as much as possible. It is taking the elements of the superior aftermarket sway bar kits and applying them to the stock unit.
The hole that will be drilled are at the ends of the sway bar. If you look at the aftermarket bars you will see 3-4 holes that allow the end links to be moved forward or backwards along the rotational axis of the bar. Moving the ends inward (towards the front of the SS) decreases the leverage against the bar and in turn increases the stiffness to resist roll. The % increase stiffness to the OE bar is unknown at this time because I have not been able to cut open the stock bar to see the wall thickness. When I do I'll be able to plug that number into the formula we have seen floating around on other related threads. It appears that the second drilled hole can be made 1-1/4" further forward on the end of the sway bar ( closest flat spot before the bar becomes round).
Remember that this upgrade / improvement cannot match the aftermarket bars. They are custom designed with additional holes and increased wall thickness.
For me any extra money goes towards other goals so I'm forced to make modifications on the cheap. I'm not unlike any of you guys. I want to mod the hell out of my SS. Just finding ways to feed the habit until I can spend real money.
If you looking for the ultimate upgrade I would recommend the aftermarket products.
