Hi there !

What sizes are those t-bars available ? Mine read "890" so I guess they´re .890 diameter. I haven´t measured my sway bar yet, what sizes were/are available ? Should I put a swaybar at the rear end ? I want this car to handle very well, I´ll only run it on the weekeneds due to fuel prices round here... :-) It can break my backbone, nevermind... Is harder(T/sway bar) really better ?

Those T-bars should be stiff enough for your car since that's what they used on big block Darts. I wouldn't go much stiffer on a street car - maybe 0.920 or 0.990" if you're really hardcore. I have 1.125" sway bars on the front of both my ('64 and '68) Darts.

I wouldn't bother with a rear sway bar. I've tried them on my Dart and they don't appreciably help handling. The road racers I've talked to/heard of concur with this opinion (Mike Ritz - Team Starfish, and Richard Ehrenberg - Green Brick).

Enjoy the Gs,

Lou

890? like part number 2535890

(and 891 on the left bar)

Those should be stock for slant sixes and some 273/318 cars.

Better ones are the V-8 "892" "893" bars

or the big block cuda "894/895" bars

what kind of car do you have?

WHOA! Good call D-man. It had not occured to me he was talking part numbers and not the bar measured diameter. I meant to say that 0.890" bars are what he wants for better handling, and I have no idea what the part numbers are. Koller Dodge or Mancini will have the T-bars for $120pr or so.

Hi guys,

my t bars are stamped "890R" and "891L". Their diameter is about .850" Car is a 72Duster 198.
Question: What to do to improve handling ? I have a front sway bar. The car is all torn apart for resto right now, so anything is possible. Has anyone a picture of installed subframe connectors ?

If you have a stock sway bar, you might want to upgrade to an aftermarket 1.125" unit w/poly bushings. Also, I would go with 0.890" or 0.920" diameter T-bars. The biggest help in handling is wider, low profile tires. Try to get at least some 215/60-14s under it.

It will take some time to get the car back on the road. I´ll have a look some good rubber ! Thanx

I would consider putting a rear sway bar on at this time if you can work it. also add a leaf to your leaf springs. These two item should only run 300$ at most and would really go nice with the front end work.

Good luck

Hi Lou,
Do you run a rear bar on either of you cars?
The rear bar is a driver preferance decision, I agree with the issues that the serious road race cars do better without a rear bar just because it is safer (and faster around the track) if the car understeers (pushes) instead of getting oversteer. (can you say spin-out?)

On the street, I like a bunch of rear sway bar. ( I have 2 rear bars under the back of my 66 wagon)
My set-up is pretty well balanced with a little low speed push, 4 wheel drift 30 to 60 mph, and oversteer at speeds above 60 ( the car is waayyy to "tail happy" above 90 but I don't drive it through curves that fast)

Rear bars are fun, it really gives the car a flat feel so you may want to try one.

Hey Doug,

I don't run a rear bar on either car, but have had one (3/4" diam??) on my '68 on and off. The '68 handles with a bit more oversteer with the rear bar, but as you said, not really faster. I like the feel slightly better with no rear bar as the car sets up the suspension and "crouches" in the corners a bit better, in my opinion. The '64 has had some oversteer lately(older rear tires I think), so I'll have to see how it handles my new wheel/tire combo I just got on there this weekend (245/45ZR16s on 16X8 rims). I like the slight understeer that I can turn into oversteer with the throttle.

I've done some 4whl drifts at 80-90 on the throttle - now THAT's entertainment.

Cheers,

Lou
