Now... i wasn't there 40 years ago... but i doubt thats how they came. If they did then the factory hype was just that, hype. That looks about normal for a non-TA. I have seen, and these are rare... at least a couple old pictures and ads/articles (i forget, i dont have them now) ov original T/A's, and the rake was there. You NEVER see this on restored T/A's. Either its an oversight ov the builder, or perhaps a too-trusting builder buying from a manufacturer with bad specs, or preference ov the builder not wanting a raked car (though i would think that these 'gold-standard' resto's would build how they came, despite what the builder likes), or as i've seen too many times, sheer laziness ov the builder. I'm obsessed with these cars, and have looked at hundreds in person, and any picture i can find online. I've only seen a few pics with what looks like a decent rake. Many ov those have aftermarket suspension aids (read: saggy leafs). Maybe these cars sagged quicker than non-T/A's?

Keep in mind thats only 40K, but its also 40 years. Time is as big an enemy as miles.




Not a lazy builder. That's Troy's T/A he had about 2000 hours into. One of the most documented and thorough T/A restos out there. Those are original date coded leaf springs the car was born with. Different angles of picture give it different looks. I have pictures of that same car that look like even more rake. Non T/A cars almost look to be sagging in the rear from the factory.

Nevermind trying to figure out what the suspension height were originally. It really is about the height and rake you want or want to maintain. Any side view pictures and measurements of your car right now?




I'm pretty sure that T/A sits lower than it did, you did say those were old springs. Heh... no camera trickery will change that. And yes, i think the normal Challengers look a little low in the ass, especially when you have stock sized tires on there. Another reason why i dont like lowered Challengers.

Anyways, i was only using the factory T/A specs as something to go on, which considering what we've talked about might not be the best idea. My car measures 14" from axle centerline to wheel lip. The front sits about an inch lower, all due to different diameter tires (305/265-50/15 currently). The tire sizes will change, i plan on 17's, but the general diameters wont too much, nor will the rake. I dont have any good side pics ov it, only front and rear. Its immobile and parked in a bad spot unfortunately.

I did find a pretty close picture ov someone else's Challenger that sits more or less how i'd like mine to look, but when i tried to post it here i somehow lost the whole post, my computer crashed, there was a citywide blackout and a plane crashed into a school full ov handicapped children.

You mean the yellow Challenger T/A? I know they did a comparison with a new SRT. Maybe the info is in there. Article must be online somewhere.

Googled it...Took some searching.

http://www.insideline.com/dodge/challeng...challenger.html


E-Max..... .93 G's skidpad
SRT-8..... .84 G's skidpad

E-Max..... 67.6 mph slalom
SRT-8..... 68.8 mph slalom

E-Max..... 123 feet 60 mph braking
SRT-8..... 118 feet 60 mph braking

.
.
.
.
Here's another article from Edmunds with SRT8 test results that are slightly different. Slower slalom, little more skid pad.

Track Test Results
0-45 mph (sec.) 3.6
0-60 mph (sec.) 5.3
0-75 mph (sec.) 7.7
1/4-mile (sec. @ mph) 13.6 @ 104.0
0-60 with 1 foot of rollout (sec.) 5.0
Braking, 30-0 mph (ft.) 29
60-0 mph (ft.) 114
Slalom, 6 x 100 ft. (mph) 67.6
Skid pad, 200-ft. diameter (lateral g) 0.85

Jacquot is legit, he is one of the best test editors around. When he worked the Ultimate Street Car Challenge, he drove ALL the cars for the skidpad test.

I cant be certain what he has in his own stable, but I think he had a 70 Charger at some point, cant confirm nor deny.

Allright. I knew you could clarify.

He just seemed to diss stuff like the hard shifting transmission and it is a Tremec; much easier shifting than a A-833. Julius got a ride in the Yellow T/A at Willow Spring from another non old car media guy that grinded the he## out the trans (not Jacquot). Some of media that drives this stuff is not real savvy.

Does Edmunds use the same slalom and skid pad for all thier test? The SRT-8 showed different slalom numbers, but close skidpad numbers. Variablity in cars I guess?

wow, you guys are smart and resourceful!

Pale Roader, I'll just answer your big question...if you want to use stock leaf springs, you can still use all the rest of the Hotchkis parts, and set your ride height with the torsion bars.

Later, if you want to optimize the performance, you can always swap and lower the car.

Elana wouldn't let us put good tires on her car. She likes the stock look.



We have lots of photos on our facebook page.

The only thing different about a 71/72 B-body kit from a E-body is the frame connectors and the rear sway bar.

I am thinking about getting the setup for my Challenger but I have b-body Dana in my car. So I would imagine the rear spring relocation brackets could not be used?

How does the rear bracket correct geometry?

You are using offset hangers instead as oppossed to moveing the axle tube mounts?

Front spring eye height is different for anti squat characteristics.

Everything else will work then? I'm planning on putting frame connectors on. Is there anyone that makes a front and rear sway bar kit?

The Hotchkis E-body front sway bar is the same as a 71-72 B-body sway bar.

There is a difference in width between the frame rails where the end link attach to the frame kick ups. I don't know how much that difference is.

I am using DrDiff offset hangers. If I moved the springs out they will interfere with my current wheel setup.
Was also thinking maybe I could use the Hotchkis front setup and for the rear use the XV or Street-lynx. Looking at the Street-lynx and it would be about $800 more than a Hotchkis rear suspension components.

Just run the Hotchkis leafs with your current offset hangers. Pick the spring eye hole closest to the Hotchkis hanger or to your rear ride height liking.

Call Drew on their techline and confirm if the Hotchkis rear adjustable sway bar works with a Dana rear end.

The Hotchkis leafs have top spring to help prevent axle hopping under heavy braking. And two long bottom springs for anti windup.

This is an A-body setup pictured below.

+1

also hotchkis are you guys working on a 4 or 5 link setup for the rear? looking for more improvement over leaf springs but not to happy about some of the 4 link design concepts that are available now through other companies..

So you've run your car with leaf springs made for handling at the track and you have found it lacking?

The Hotchkis Challenger at the Optima Challenge in Detroit was like 4th fast road course and 1st or 2nd autocross. Over like 50 cars. Most with fabricated front suspension and most with 4 links.

Thats great if u have a challenger - but they have nothing for the rear of a 71-72 roadrunner

66-70 B-bodies and 71-72 B-bodies all have interchangable rear leaf springs. The 68-70 and 71-72 B-bodies are in the same range of rear weights.

So run the 68-70 Hotchkis B-body spring: http://www.hotchkis.net/mopar_b_body_geometry_corrected_sport_leaf_springs.html
