Haha. See! I told you #6 bin the contest was tricky.

All it was .. was a spare adjustment knob sitting there. I figured it would make for some funny guesses.

Howdy everyone!

Our client Ron Ver Mulm installed one of our GT Decoupled 3-Links in his autocross car recently & used his GoPro to capture the first runs. After watching the video, it was easy for me to know the rebound valving & spring rate are spot on, but his application needs stiffer compression valving & a taller, softer & more progressive bump stop. He ran his fastest runs ever with our new GT Decoupled 3-Link, over his conventional 3-link. After we change the compression valving & bump stop, he'll most likely shave another .3-.4 off his lap times.

For those not in the know ... the decoupled 3-link is the highest grip, fastest rear suspension available period. The shock version won so many Trans Am races back in the day, they outlawed it. (You can run our TA version legally in Trans Am, which uses poly bushings & no shock.)

We utilize this "shock controlled" decoupled 3-Link rear suspension in all of our GT Track-Warrior cars featured in this thread.
* Greg Weld's 70 Mustang
* Mark Milliron's 69 Torino
* Scott Pomeroy's 68 Chevelle
* Robert Taylor's 47 REO Speedwagon Truck

I assume your talking about the the bump stop on the upper link? What are you looking for when you want it to be taller, the bushing to be in contact during full travel? Just want to understand how this works (since I have one!) and what your seeing that the video shows.

Hey Craig!

In this fella's autocross application, the "actions" of the Decoupled 3-Link happen in shorter time frames. Add in the abrupt on/off throttle driving style ... and yes, he would benefit from a taller, softer bump stop to be in contact during full travel. Under hard acceleration, when the top link bracket of the housing is pulled all the way back, we'd be OK with a small gap, or just barely squeezing a very soft (low spring rate) bump stop. Then as the driver lifts & brakes, and the top link bracket of the housing falls forward, a taller, softer bump stop would control it sooner & slow the decel link compression.

We don't need that for road courses, where the "actions" of the Decoupled 3-Link happen over longer time frames. What he has here, as do you, is our setup optimum for road courses. We want the top link bracket of the housing to move freely under acceleration with no additional spring rate on the links, until we lift & brake on corner entry.

Got it, thank you. So would it be beneficial to have both, and swap out bushings depending on whether its road course or AutoX?

Yes ... to a degree. If you wanted to optimize every tenth of a second lap times, I'd have two setups. If not, and you're planning to both autocross & road race (or track) the car ... we should lean towards the middle.
