Anyone use the complete UMI rotojoint rear end control arm set?

Those delrin raced roto joins will never fail if you keep them clean.

We ran them in a G body with a 5 speed and a big inch BBC.
Lots of seriously abusive hi rpm starts... Never a problem.

Here are some pics I found on my phone.
Pic 1 zoom in close enough to see the upper arm.
Pic 2 is the lower arm and HR bar bracket.

Once they're setup and aligned etc, it's been worth the trouble to no longer spin the tires really.

BTW high 11s is somewhat easy for our platform these days and that goal will last until the next minute after you hit that time. LOL

Thanks for the pictures!. I would like to go faster but 11.49 require roll bar? I have a low mileage car that i mostly cruise but I want to have a little fun with it too.

Well you don't have to do a full 1/4 pass or need the track for timing it so you can ditch the roll bar.

Dragy and 1/8 mile are enough for fun and keeping it looking original interior, I am.
You don't need to do anything illegal on the street, just be super quick and it'll be fun within the limits.

Torque and traction, that's the real TT that matters.

You don't need to do anything illegal on the street,

Im going to absolutely disagree with this statement

roll bar.

Dragy and 1/8 mile are enough

Most of the racing is all 1/8 mile
And the draggy is spot on especially in et

I have a draggy, just haven't found a good area next to me to try it. I have been tuning on the freeway on ramps. There is a long on ramp near me with a little incline so it builds boost and I can record and monitor everything with powerlogger.
