Finishing up a long time project 2000 WS6 car.
BMR K-member, A-arms, swaybars, torque arm, panhard rod bar, MAC springs(will be replaced by coilovers within the year) stock shocks, 275 17's up front, 295's in the rear, and stroker motor LS2 swap. 12 bolt will go in within the month.

Anyone have any good street/agressive street/road course track setups?

I hate to tell you this, but the BMR k-member will fail under heavy cornering. The part is not meant to be used on a road race car, or any car that will see any time on the track.

I had mine aligned to the "trackbird specs" when the
install was done.

I do not believe cornering forces are what kills these
K-members, at least not directly. The weld I think
fail from impact-initiated cracks which propagate over
time & load. But the stress on cornering puts the cross-
tube welds in compression, it seems to me (main force is
on the outside tire and the rest of the car pushes into it).

If I had the opportunity I would reinforce the two weld
circles before I put it to any severe duty. But in merely
enthusiastic cornering, it's "so far, so good" for me after
a couple of years' service. Which is nice since when I
bought the piece it -did- claim to be up to street duty
(that claim was later replaced with a more cautionary
description).

Cool deal man. I didn't know that these couldn't be used for rough duty. The customer that owns the car has a few vehicles, so this one is just for fun highway blasts, some drag duty, and maybe some other fun events. I hope it holds up for him.

Thanks for your time.

I guess I can do a search for the "trackbird" specs, right?

Thanks again, J

With all the money going into that, why stock shocks (or does it have the koni optional shocks on it? ),

For alignment, I would go for 1.5-2 degrees negative camber, as much castor as you can get, and adjust the toe based on the application.

Only if you corner on 2 wheels ...

Good, valid question. The kid, my cousin who owns it, has a MTI Z07, fully worked, an 05 GTO with full suspension, tune, bolt-ons, Chevy truck, and this TA. The car is, belive it or not, on a budget. The amount of money spent in it, was all at my cost, and he's my cousin, so, no labor. ANyway's....coil-overs will soon be added so, that the reason for the delay on the shocks.

This car, was never ment to be fast, it just had a motor problem, so I ended up doing the LS2 402 swap, and then the mission just started to escalate. You know what I mean? lol.

Here's whay I saved & gave to the mechanic:

Trackbird's setup:
I am running:
-1.3 camber
4.5 caster
1/32nd inch toe out (yes, out)

It has a slightly visible camber to the front, not like
rice-boy goofy but "businesslike". Feels stable at high
(for me) speeds, corners with no surprises and has no
evident unevenness of tire wear.
