At what ET do you go to a Wish bone in?

Just curious, when does it really help? Is it for hard leaving cars or what determines when to switch?

My Duster and S/P Cuda both have diagonal links and anti sway bars.
The Duster went 10.00 at 134.+ MPH on ET Street tires ladder bar and coil overs with the diagonal link, steady as a Lincoln on the street and strip up
The Cuda has gone 8.86 at 150.+ MPH with no issues, it goes straight as a bullet, unless it spins on the line. 4 link with coil overs and diagonal link and anti sway bar mounted behind the Dana 60 up

Ohhhhkay.......I do know the radial cars need to have them. My car runs 9.40's....And it runs pretty straight even when it breaks the big tires loose. Just wondering though, if there might be some gain in the 60ft with a wishbone.

Mine runs mid 1.2x 60ft @3325 using a diagonal link. Has 750 passes on it. Never bent anything. Changed the rod ends at 725 passes but they were not loose.

Warren Johnson ran a diagonal link in Pro Stock...I am good friends with Gary Hanson he loves telling that story about Warren getting cars and removing the wishbone. Gary owns his own chassis shop and ran Pro Stock for a long time. He will install wishbones but prefers a diagonal link. Thye both do the same job.

I have run high 7's with a Diagonal link with a 4 link and the Vette runs 7's with a diagonal link and ladder bars. Been 1.07 60' with one.

the only issue I have seen with Diagonal links is if they are under sized.. . the longer they get the bigger around they need to be. They will bend if too small a dia on hard leaving cars and in situations where the car gets out of shape.

The diagonal link on ladder bars with coil overs works good, especially on the street up boogie scope twocents

I used the WB only backwards, pivot on the housing, The Y part at the front of lower bar mounts on 4 link. I didn’t want a broken u-joint dropping the shaft into either.

My SC/SG friend runs X links, they moved away from wishbones. It's throttle stop stuff though so I'm not sure how applicable it is to door cars.

Is the preference of the diagonal link because of the weight reduction? Or because it functions better? I imagine a wishbone being heavier and requiring more maintenance.

Most of the better chassis shops in SO CA years ago told me to use the KISS principle on all race cars. up AKA as "Keep It Simple, Stupid" up boogie
Works good, lasts a long time boogie up

^^^ Agree.

I had a wishbone. At the time I thought they were the way to go. Changed my mind when I discovered how much wear the slip joint incurred. Car was unstable. Switched to large diameter 1 1/4 diagonal and could not believe the difference. Car ran 4.70. 1.04 60".
