Default Are T1 bars best option for C5Z?

After installing the DRM ducts, the Pfadts are out. Really liked their Heavy Rate sways. Anything else out there that are a better value than T1s for $700? Running stock bars now with Pfadt adj shocks. Currently running 18" square set up with R80s. Had to send my shocks in as bump stop bushings dissappeared. Pfadt says that happens when sways are not stiff enough. Only do HPDEs, no competition stuff and car is dd also. Suggestions?

I don't know if they are the "best" option, but I'm happy with them even for street use.

I run them on my PTA/TTA car. Easy to find used on the forums and a proven setup. Sometimes I wish the front bar was adjustable like the rear. At times I'd like to take just a little bit of stiffness out of the front, but that's just because my car pushes a little on 255s... works fine on 275s and up.

They are great bars. A little stiff in the rear for my liking, but it works.

Would the T1 Sachs shocks be a better match with the T1 than the Pfadts shocks or a downgrade?

I run the T1 in the front with the stock rear Z bar and like it quite well

I ran the T1 shocks at a couple of events and never really cared for them. The '04Z shock works really well with them. Maybe you can find a shock dyno graph to compare the '04 and the Pfadt??

Is anyone running Addco bars? They offer a variety of sizes and styles(solid or tubular) some of which seem close to T1 stiffness(based on diameters). The bars are also dirt cheap(compared to T1).

From Mid America's website

Tech Note: Our 25.4 Tubular Rear Sway Bar is optimized for use with both the 35mm and 32mm Tubular Front Sway Bars. When using our 35mm Solid Front Sway Bar, it is recommended you pair it with our 25.4mm Solid Rear Sway Bar for best handling. Our 22mm Solid Rear Sway Bar is recommended for use with our 32mm Solid Front Sway Bar.

We run the Pfadt adjustable shocks and T1 bars on our TTA car and really like the way the car handles - it's nice to have the adjustability from track to track (or in your case street to track). I've had a couple customers have issues with the bump stops on the Pfadt shocks but that's not because the sway bars are too soft it's because the springs are too soft.
In both cases that we've had the customer either didn't wan't to go up in spring rate (DD + expense) or we couldn't because of class rules.
The thing about adjustable shocks is that you have to drive consistant enough to know weather you are going the right way or not. That's what's nice about non-adjustables put them on and drive.

That is the main reason I wouldn't have a problem selling my Pfadts and getting the Sachs. The adj are probably more shock than my skill.

Anyone tried these bars from Xplosive:

http://forums.corvetteforum.com/c5-p...le-sway-b.html

$250 less than the T1s. Not sure if size the determining factor for stiffness, but they are close in size to the T1s.

I run the T1 bars and like them, but I don't have much to compare to.

Car #1: Stock 04 Z shocks, T1 bars, stock springs. This is my racecar. I hold the 2010 time trial title in my class in NASA (TTA) and several track records around the region.

Car #2: 00 FRC with Z06 bars and stock springs and shocks (OEM, never changed). This is my wife's track car. I find it has more roll than I like, and it seems a lot less positive, but we seldom run the same tires, so it's hard to really say.

Car #3: 01 Convertible, stock bars (Z51) solid end links, stock springs and shocks. This car needs shocks, and handles most softly of all of them. It's the road car, and works well for that.

Of all the cars, I like the racecar the best, but I'm biased. I can say that I drove the T1 bars on the street for a couple of years before I turned it into a straight racecar, and they were not bad.

Soften the bushings?

Yeah it crossed my mind, but I'm not sure where I'd get rubber bushings for a T1 front bar.

Try the stock bar with the T1 front.

I have not done it, but the OD is the same on all these GM bars, so if you got a rubber bushing from a smaller bar & opened up the ID to the T1 size it might work. You would have to "hand fit" it but it would be cheap enough to try.

Maybe one of those circular sanding disks that fit on a drill, or a drill press, with a circular saw (hole) cutter.

If you figure it out maybe you could sell some to us.

my biggest beef with the T1's is the front is a boat anchor.

the balance is good though

I run T1 bars on my car all the time and no complaints.

I'm very happy with them on the track as well as on the street. Last track outing was on 04 ZO6 shocks that were way past worn, waiting to try them with the C6 ZO6 shocks I recently put on the car (don't have the budget for coilovers)
