You know Glenn, I see tons of cars running the GM discs, even T buckets, and the guys seem to be ok with them. For us, they just seemed to be problematic, so we are pulling them off.

What we were getting on his car was death wobble. Without any warning the front would go nuts, to the point of shaking the horn button off of the steering wheel! It didn't do it al the time and no particular thing seemed to trigger it, but we just knew it had to be corrected or he was going to get hurt.

I bought the front end setup off of Ebay. Everything was freshly chrome plated and nice, and the ad said they had just replaced this setup with Wilwoods instead. After we started having problems I miked the spindles and found one was turned about 6 thousandths too much in the area where the outer wheel bearing goes. You could phyically move the bearing around on the spindle slightly.

I had a discussion with Mickey Luria from Total Performance at Daytona and the first question he asked was "you don't have GM brakes on the car, do you?" He went on to say they hear this all the time, especially at about 50-55 mph, where the front starts to shake. He attributed it to too much rotating mass from the heavy GM rotors and the heavy caliper sitting back there.

As I mentioned in my previous post, I found a whole lot of problems with the alignment of the car, and the bent rear rim wasn't helping either, so I have no idea if the front brakes would now be ok because of those areas being corrected.........but we are just not going to take any chances and are going to a lighter Wilwood setup. We won't even give or sell these spindles to anyone because I wonder if the previous guy also had problems which is why HE changed them out. I just know over a addional $ 1000 I am not going to see my Son hurt himself, someone else, or worse. We want to make sure we have eliminated every possible possibility from the equation.

But, like I said, I see cars on forums and all around me using these, so a lot of people must have luck with them.
