Agreed, one of the best, cheap handling upgrades you can do. A small warning, my dad got the lindsey racing ones and they caused his swaybar to hit the a/c compressor. My Tarret brackets did not have the same issue. Still the best $42 i've spent.

Did you buy the Rennbay or KLA ones? I too did the brackets, and went with the KLAs, I noticed the difference, and love them. Cheap, noticeable mod, you cant go wrong.

Be aware that these can and do shear in half sometimes in extreme conditions.

Been there done that. Watkins Glen, going up the esses. Instant terminal oversteer. I hate when that happens. I'm pretty sure there was no such bracket in the Cup days, so I'm guessing they just swapped them out as a wear item. Wish the PCA had been as vocal about them as they were about the control arms. I spent $1600 on Fabcar arms, so I think I woulda bought the bracket if they'd been available in the last century.

Kelly Moss had swaybar bracket supports, likely going back to their Firehawk days. Have not seen them available/sold for years, but stumble across them on a track car every so often. The supports mount forward of the factory brackets and bolt to the frame rail, not to the rear like the current aftermarket pieces. I have some of each, and dont really have a preference to either design/type.

Jim,

I have seen a picture of those before, but I didn't know who made them, Thanks.

Was it the factory sway bar mount that failed? or one of the re-enforcement brackets? Were you running a set of re-enforcements? Just trying to figure out if having these brackets is safer/better or more dangerous/worse than stock.

xsboost90 05-03-2012 12:04 AM

I've personally never used these on any car. My belief is that using too large a sway bar with too soft of a spring ends up making the sway bar move around more, necessitating brackets like these. Ive never had a sway bar pop out of a mount or bend like many say who buy the supports. Not saying they don't work, just never needed them.

dykaar 05-03-2012 12:26 AM

Look at the picture:

The bracket split through the bolt holes. You can see from the level of rust that the crack took time to propagate across the bracket. Just a little flex over ~20 years and SNAP! you're in the armco. Feh.

I used them on my 924S with a 24mm sway and it was a nice improvement. On my current 944S I'm using the same brackets with the 26.8mm. Even if the mounts were not moving around due to a large sway bar, i would think even for a stock sway it would prevent an incident like dougs by not allowing the stock bracket to move and fatigue as easily. Cheap insurance.

I had a few sets made at work. using mine with a 26.8mm bar. They're great, very happy.

xsboost90 05-03-2012 08:31 AM

makes sense, i guess most cars have the sway bar mounted solid up top instead of hanging, maybe i'll pick up a set and see how they do.

Doug,

Also - forgot to mention it earlier. Probably the more common failure than breaking the factory hangers, is distortion and fatigue cracking of the frame rails at the mounting points. There are some threads here that show pictures of various damaged frame rails.

The factory was aware of that problem, and did reinforce the frame rails at the swaybar hanger mounting points on the Turbo Cup/Motorsport cars.

pettybird 05-03-2012 01:20 PM

was that modification also made on the 951S street cars? I know they did the strut tower pieces...
