The "bigger" brake upgrade was performed in Jan, 2001. I didn't want to pay the large price of the aftermarket upper control arms, so a little research netted a place called www.ubmachine.com that had arms in their catalog for $48 a piece! After some phone conversations, they would build me two arms to my specifications. The upper ball joint is originally specified for late '60s full size Chryslers and is a screw-in type. The stud in the joint is larger than the GM, so UB Machine re-reamed the spindle holes to match (for $15 each). The Chrysler upper joint is as large as the GM lower one! I also had them put nylon bushings in, instead of the metal on metal the circle trackers use. They are greasable and should last a long time with regular maintenance.

So far, the results have been fantastic. The resulting, negative camber curve (about 1 degree per inch from ride height to bump) really helps the car hug the road. I was using Monte SS spec springs (420 lb/in), so the increase in spring rate let me use a smaller front sway bar, with a better ride. Even with solid bushings in both upper and lower arms, the ride is still very nice, but very controlled and smooth. The LS really likes to cruise at 80+ mph on the highway now and is ridiculously easy to drive it!

The increase in braking power is the best part. I didn't think the 11" rotors would be that big of an increase, but some math showed that they have almost 30% more swept area (each!) than the stock 10.5" rotors do. The brakes really feel powerful now, whereas before, a lot of planning was required for most fast stops!

So far, I have been able to make a best run of 12.545 @ 107.6 mph with this combo and the Vigilante converter installed.

Very reliable package and I drive it everyday. The AC works great and has been converted to 134a. The car looks stock from the outside, and it looks like a "granny" car. No wonder nobody wants to race :(
