I'm planning on building my daily driver Charger 440 and it should be around 550 hp. I was wondering what suspension options/brands would be good to handle the power without being drag racing stiff. What would be necessary for the front? So far im thinking lower control arm rebuild kit (stiffening plate, torsion bar adjuster, and pivot shaft), adjustable strut rods, full front end rebuild kit with adjustable tie rods. All from PST, and from Firm Feel im thinking bilstein shocks (front and rear), fast ratio pitman/idler arm, and stage 2 steering box. Also planning on getting caltracs. Other than a center link, and possibly tubular UCA's, torsion bars, and a swaybar, what else would I need? (Id love suggestions on brands/sizes for the torsion bars and swaybar) I also already have XHD springs.

Your stock torsion bar adjuster and pivot shaft should be fine. Inspect and reuse.

Doesn’t should like a build that would benefit from tubular upper control arms. Install offset upper bushings in you current UCA’s and align accordingly.

Might want to consider Borgenson box with stock pitman and idler to give you 14:1 ratio.

1” t-bars and sway bars will be fine.

Caltracs are for drag racing not handling. If you want street/strip they are fine for hooking up power in a straight line with no turning involved. It's about what do you want to do with the car.

I understand that theyre not for handling, but if i lower the preload on the street itd feel no different plus i get the benefits on the strip.

Cal-tracs are a fine tuning tool to get the last hundredths out of a drag racing combination. They are not a traction aiding device that will plant a street radial and install bite to tires that do not already have it present.

The originator of Cal-tracs developed them for his Mustang that had symetrical leafs so they would act more like a non-symetrical Mopar spring in a class where relocated mounts points was prohibited. I've know some very good class racers that saw no more improvement with cal-tracs than very scienced out sets of SS springs. Now, the cal-trac is more easily adjusted than removing and doctoring a leaf, so there is some advantage to them.

For what you would spend on Cal-tracs, you would probably be dollars and e.t. ahead to get some slicks and steel wheels for drag strip use.

You do realize that this forum caters to cars that turn corners and run on road courses, right? Here, we don't concern ourselves with 90/10 shocks, slicks, drag radials or trans-brakes!
A car set up for drag racing only will be a poor handling car on the street. A car set up for great handling can still be a decent drag racer.
Me? My 70 Charger has 1.15 torsion bars from Moparts sponsor BAC, a 1 1/4" front sway bar, MP HD leaf springs, a 3/4" rear sway bar, Bilstien shocks, Firm Feel stage 3 steering box, Fast ratio idler and pitman arms, MOOG offset UCA bushings, a welded and gusseted K member, reinforced LCAs and 18" wheels with 100 TW Nitto NT-05 tires.
It handles quite well. It rides decent too.

I've had dedicated circle track cars, dedicated drag cars, dual purpose street/strip cars and street handling cars. They all come with their own quirks when used in their specific environment or on street type applications. I have noticed that the handling cars were actually the most consistent at the drag strip. They weren't the quickest or fastest, but were consistent. If you are bracket racing, this is a much more desirable attribute than an ultimate e.t. or m.p.h.

Case in point is a stock eliminator style build I had with a 360, high stall convertor and steep gears. Ran low to mid 12s @110 in Denver. It had light t-bars, no sway bars, drag shocks and a highly sorted SS spring set. Went straight as an arrow with the front tires just skimming the surface off the line, but wallowed like a drunk around corners and was subject to e.t. changes based on atmospheric conditions.

After running this combo for a couple of years, I pulled the engine and trans and dropped them into a purpose built handling car with big t-bars, big sway bars, high pressure shocks and wide tires all around. Same engine, convertor and trans. This car with the exact same powertrain combo as the drag car ran consistent 13.2 @110 run after run after run. It wasn't impressive to look at as it left the line and it hardly moved around as it went down the track. I only gave up a second in e.t., but the consistency of it was phenomenal.

After playing around in various types of cars over the years, all my street cars are all built towards handling now days. They are simply more fun wherever you drive them. If I ever go back to drag racing, it won't be in a door car any more.

I would not use caltracs on anything other than a drag car. they make the ride rough and it will be worse around corners.

Dad and I put a set onto his Diplomat coupe last year and I didn't think it was bad at all. Even has the solid aluminum front spring bushing installed. Car is setup for handling with high rate torsion bars, sway bars and stiff shocks.

We did a before and after cruise down the same stretch of road to compare. This is route I was planning to take in the Spring.

on an all out road course at speeds the caltracs won't allow enough travel and the outside wheel will likely not have a great contact patch.
