Coupe sway bars

[TNcoupe]

What are some options on sway bar kits for the Coupe. Have nearly 1000 miles on mine on the street now and it has a goofy mid corner wiggle when the suspension settles after it loads up. Looking for something to tighten it up a little bit. Also gonna try some different front end settings with possibly a little more caster to help mid corner/ corner exit.


BTW, did a search and couldnt find much recent stuff or Coupe specific stuff.

I looked at those but didnt know if they were compatible with the Coupe. I didnt know if the chassis was different on the rear of the Coupe compared to the Roadster.

Mike Forte has a front sway bar he developed for the coupe front, not sure if he has one for the rear.

Call VPM. I got my front sway bar from them this spring. If I recall correctly, he said the rear one will work on the coupe as well.

I used VPMs on the front and back of mine:

TN the wiggle you mention, what kind wiggle is it? Is it oversteer or understeer? It matters as it will dictate what end the bar needs to go on. If it is understeering and you put the bar on the front it will make matters worse. Also if you put the same strength bar on the front and back it will not likely change the balance at all.

The wiggle feels like the initial compression of the spring then the suspension loads on that corner and compresses further. This causes it to feel like theres a flat spot in the steering mid corner to exit. I guess it would be more toward the understeer since it requires a little more steering input once it loads up. Its not to the point of pushing uncontrollably. Stiffer spring rates could possibly solve the problem. I may stick my GoPro under there to see whats happening.

Did you make sure the front suspension moves freely up and down? I had to remove the powder coating from inside the lower control arms where the rubber bushings press in to get the arms to move freely. Added friction to any suspension piece can cause weird handling behavior. You might also check to make sure no suspension piece is loose or binding. I haven’t gotten mine on the road yet but calculated numbers for the front to rear roll couple indicates the rear could use a little more stiffness at least on the IRS option.
