First Thing You Noticed After You Installed 1" Sway Bar?

I have a '65 2+2 and am trying to get an idea what going to 1" sway bar will be like vs just replacing the bushings and end link rubber.

The bar on there now is 11/16 according to my 1992 Craftsman wrench.

I have a monte carlo bar + export brace installed. The car is a weekend driver and my garage girlfriend .

Thank you.

I installed it and autocrossed a couple of times before going full gonzo on my front suspension. It makes it feel like you are steering a yacht instead of a ship. A little less lean in the turns and that's a great thing! No downside to the 1" bar. As stated 1,000,000 times, the Shelby-Arning drop is the best thing that can be done to these cars.

Flatter cornering. As cheap and easy of a swap as it is, try it and find out.

Ok. I'll be the Debbie Downer........ a fatter front bar will give you less
lean but it'll still push mightily at the extreme.

I did the 1" bar , afterwards I was able to swerve into and out of the passing lane without fear of crashing. Doing the UCA drop and cutting a half loop from my 620's also helped alot

To counter the "push", I installed a rear bar. More balanced, now.

Do the Shelby/Arning drop if you haven't done that already. Then you'll definitely notice a difference in how she handles when the entire front end is working together with that 1" bar. And good shocks are a must too! Konis or Bilstiens - I'm running Koni's on mine.

We have a 65 Fastback that we added 620 coils with Konis, but everything else was factory stock for a C code car. The ride was stiff and handling improved a little with the 620s, but still didn't feel right as the car still leaned through the turns. We added a single piece export brace, monte carlo bar, and subframe connectors, which helped eliminate some flex. We then installed a 1" swaybar alongwith the 1" Shelby drop and it feels like a completely different car with the new geometry. We went on to add a 3/4 rear swaybar and mid eye leaf springs to level the car. It handles much more like a modern car, but still have that vintage feel with the solid rear axle. Each upgrade contributed to improved handling, but I'd say the two single parts that made the most significant and improved changes to the ride would be the Shelby drop and the 1" swaybar. The 620s may be too harsh for some, so cut GT coils (480 I think) could be a nice option. Now I wish we had added torque boxes to strengthen the unibody.

In 2001, I put 600# 1" drop springs on my car, along with a 1" swaybar and some KYB gas-a-just shocks along with the Shelby drop, all at once.

Before, my car drove almost exactly like a powerboat. It leaned far over as it rolled into corners when I pushed things, tires howling as the outer front pitched over onto its sidewall. Long after the car had made the corner, I was still there cranking the wheel, straightening things out. The soft, cushy ride wasn't bad, but the angle of the car in corners left a lot to be desired. It wallowed around like an old sow, if you tried to slalom, and because there was so much weight transfer from side to side, it took forever to finish rocking as you transitioned from one direction to the other.

After the changes, my car's ride was still quite comfortable out on the road or in town. The difference in cornering was nothing short of miraculous. My car doesn't lean appreciably, steering is tighter, and all the marshmallowy wallowing is just gone. I'd do it again in a heartbeat, if I had to choose between the two. No regrets whatsoever, and in every way, it was a vast improvement.

It may be that at the limits of traction, things can happen quickly with the stiffer swaybar. But having daily driven the car for years, in ice, snow, and rain, I never ran into any handling issues that seemed out of place or unpredictable. In fact, I once drove to work 15 miles on solid black ice, when my neighbor's 'new' Camaro literally couldn't even get out of its own parking spot. I did have a wild spinout in rain once doing 75 mph down the freeway, due to a passenger rear tire blowout right after I got the car. But that was BEFORE the changes. I have to say, I think I could've saved things and avoided that heart-racing event with the upgraded front end parts. Thankfully the only damage was minor denting of the rear quarter from the tread hammering my undercarriage.

I noticed tighter response to steering inputs at all times, driving easy or driving hard.

One thing to remember, if you cut a coil spring, it actually looses some of its rate. A cut 620 coil spring will be less than 620 in addition to being shorter. Here's a couple of articles on spring rate and how to calculate

As with everything, it depends on the rest of the combination, namely relative F/R spring stiffness. I ran a small adj. rear bar on my '65, on the softest setting, and it was pretty well balanced. 600# spring / 1" bar front, maybe 165# / 5/8" bar on the rear ?

I've not done the drop yet. Looks like a great mod.
