DRM trailing arm brackets?
As above anybody using?
Stated to improve traction and reduce "anti squat.That is give more "squat"
However I believe the squat on launch with the IRS is lifting a portion of the tyre off the ground.Wear pattern on tyre after run shows less wear on outer 4".
6" of traction on a 10" wide tyre!

You might try posting in the "Autocrossing and Roadracing" forum.
I think this mod is more of interest in those circles and you'll have
better success.
Perhaps just post a link there pointing people to this thread to
keep answers in one place.
"A & R" can be located by choosing 'General Corvette' from the choices
that appears beneath the 'Forums' item on the main menu bar.

IMO, those trailing arm brackets are not good for drag racing. They were originally designed to prevent the rear from lifting during hard braking. Then they started marketing them to drag racers. But your observation is correct....you dont want to increase squat.

But, with the camber brackets and the the trailing brackets I have a car that handles like it is on a slot-track. Tyre (spelled correctly for you
) wear is even and the suspension geometry stays consistent through the entire travel of the tyre. On the track, it made a huge difference, and makes MY car very fast around corners and it hooks up pretty good too!Just need me some drag radials to see what it can really do down the 1/4...best time of 12.6 @ 115 mph with a 2-point something 60'.

Everything else is purchased...
The builder has just finished one exactly like mine with ONE minor difference. He bolted a Gale Banks twin-turbo kit on it. Dynoed at 1120 HP
Trying to talk me into it as well...

I talked to a road racer before I bought mine and he said they helped forward traction more than anything else, believe it or not. I was having a helluva time with this for a while on street tires and installing the DRM camber brackets is one of the things I did that did help with this.

So in a drag racing context ,the camber brackets should be more usefull as they are claimed to reduce camber change which is what we are getting when the bum drops on acceleration.
Last time out I was getting 1.84s on street tyres which I am more than happy about but can see there is more potential if could get more of the tyre on the track.

Hey rod
I'm using both these and the DRM camber brackets on my car.
I fitted them years ago when I rebushed the rear suspension so it was difficult to get a subjective back-to-back comparison in terms of whether they aid straightline traction. To be honest though I couldn't really feel the difference in a straight line. I'm not sure if this is because my butt isn't sensitive enough to notice the difference, my suspension is too firm to feel the difference or they don't make a difference you can feel.
The car definiteley felt more stable under cornering though...
Those are healthy 60ft times. I'm still struggling to get below 2.0 60ft times with drag radials (working on my new launch technique).
I don't know about the trailing arm brackets but I would definitely give the camber brackets a look based on what they are supposed to do and the Corvette Fever article I read a while back which detailed the reduction in camber change throughout the range of suspension travel...

I've always been at the wrong end of the track to see your launch so I can't comment on your camber change.
The track is prepared better for the bracket meets than the street meets,although I have done 1.89 at night.
If you consider you can't get a finger between the guard and tyre you can see how much lift I was getting.

Maybe you should run the next Bracket meeting , it's lonely being the only Vette there and being one of the few cars on street tyres

I'm definitely open to running at a bracket meet. I plan on joining ANDRA soon so I can go to the test and tune days because as I understand it they prep the track for those days. Downside is you probably won't get too many runs in.
Have you gone to a private track hire? Cost is $200 per car but there are only 50 cars. Last time I went I got 15 passes in (and that was including parking the car for a few hours because I wanted to watch). They don't prep the track but you get plenty of passes in. If you want, I have been invited to one on 4/9/05 (Father's day) and can get a few extra cars in if you are interested.
I need a sub 2.0 to get that 12 I have been aiming for. I have a few more things waiting to go onto the car so if I don't get it in the next few meets I will be pulling her apart around Christmas time.
My car is probably a bad example as far as drag racing goes if anything as it is biased towards circuit work in its setup but I wanted to chime in with my two cents about the brackets. I can dig up that article about the camber brackets to show you at some point if you like...

I spent 3 yrs in Japan and quite a lot of time in the UK...and I still chuckle when I see a LHD car being driven from the passengers seat.
Must not be a whole bunch of Corvettes down under...
