Ha. Yeah roads are pretty decent around here. Except for bridges. I guess they figure that if the bridge is within about 2 feet of the height of the road, that's close enough. At 80 MPH, you hardly notice it in an SUV, but I swear if I didn't have my seat belt on in my Camaro, I would have been ejected out the t-top.


So I just had a 30 minute conversation with a guy at UMI (I'm bored). He was honest and told me the only problem they had with the crossmember was the lower a arms could slip. So they added locking tabs to fix that. He also said it would be smart to grind the powder coating off so the bolt can grab metal instead of the paint. Other than guys pulling 3' wheelies and slamming them back to earth, they haven't had any structural failures. It does save something like 25 lbs, and adds a ton of room for headers. At the same time, he told me that while it's always great to get weight off the nose, there are probably better ways to make the car faster, and I know he's right.

The cool thing is he said they are putting a ton of effort into Fbodys.

Not long ago a corvette racer (forgot his name) jumped in UMI's 4th gen. It's making stupid power and has all of UMI's goodies on it, but is still full weight. His first time out, this guy was faster than in his SCCA winning corvette. He was so impressed he is building a 4th gen to try to win LS fest.


So maybe I should just run the stock cross member and put that money towards their shock package. I'm on strano's koni front, bilstein rear shocks that are not only about 6 years old (not many miles though), they were designed for 550/150? springs. I'm running 750/250, so I'm sure proper shocks would make a difference.

I need more moneys.....

I think that was Danny Popp. I bought my Koni DA's for my original 2002 from him. He used to autocross with the local SCCA on occasion. Danny is FAST.

I ordered the UMI coilovers today. I'll have some experience with them fairly soon.

He still does. He is actually making a reappearance at the national events this year, or at least the ones here in Ohio.

Would run the K-member if I could, but not able to in ESP and I don't think it's worth the weight penalty in CP.
