Hi

Looking for help with tips on how to lower the front suspension after the TVS install. I hope all the relevant details are below.  I'm wondering if I go with a torque bar a little less stiff  than the 1.14 from Borgeson it will help lower it, but open to any ideas to help get the stance right for a pro-tour themed car.

How I got here...
Bought my '74 all-Canadian car back in September '17. In stock form with a crate 290hp 360 and very low vacuum it handled like a 44 year old car.  Easy decision to make 2018 the year of making the car safer.  Started with Holley Terminator EFI and Brembo disk brakes all around.

I took the advice from this thread http://www.cuda-challenger.com/cc/index.php?topic=95660.0 and did the following work;

-Completely rebuild front end- new bushings (UCA and LCA), ball joints, tie rod ends, pitman & idler
-Hotchkis TVS full kit
-Bilstein shocks
-7103 Moog offset UCA bushings w/ stock UCAs
-New Rims & Tires - 17"x8" front and 17" x 9" rears with 255f /285r tire width (minor grinding required)
-Borgeson power steering box & Torque bars
-Adjustable strut rods
-Solid tubular tie rod adjusters

here is a pic.

Just loosen the 3/4" bolts on the lower control arms to lower the car [unload the weight of the front end off the ground].

You'll likely want to realign it after side the static height changes, but it'll lower it all you want.

Looks like you may have a pretty short rear tire on it, it may behoove you to split the difference and raise the rear slightly.

As mentioned, the torsion bar adjusters are the bolts tucked up inside the lwr cntrl arms, but count the number of turns you take on each one and duplicate that on the other. It doesn't take a large amount of turning to make a change and the large torsion bars you've now got in it will handle the load, even lowered. Unless you're shooting for that "down in the weeds" look, you may, as mentioned, want to lift the rear an inch or so and that'll require different leafs or re-arched current ones. Nice looking car no matter what way it sits though.  :cheers:
