I mainly cruise the car but will occasionally take it to the drag strip. Drag radial. Goal is high 11s consistently. I have used regular urethane on other vehicles and they would actually wear out and make a ton of noise. These rotojoints seem to be a better option on paper, but have never used them in real life. I am also in california with tons of potholes on the roads. If not a good choice I will figure something else out.

I don't have that exact set, but they are a superior solution to poly in every circumstance as long as you keep up with them. If you street drive it at all, you'll want to keep them clean and periodically disassemble them and get all the trash out. Might want to get spare delrin inserts for them to go in the trunk.

They will not work in tandem with a Watts link or panhard bar. The suspension binds and the roto joints on the UCAs at the frame side will explode. BTDT.

Thanks for the quick reponse! Is that setup not very good for drag racing? I come from European cars so I never expect this car to turn at all so I just want a straight line cruiser. Do you have any suggestions?

Got those arms, the theory seemed worth the money if I could get the weight to transfer and tires etc to hook. I got the rear end aligned and with all the components the car hooks the way I want but it's many pieces, not just control arms.

The stock suspension needs nothing to run into the high 11s
It can even be done with the sway bars in.

Thanks! Cost is not the problem for some stuff but I just dont want to add unnecessary parts. I wont be drag racing every weekend. Maybe 5 times a year. High 11s are my goal just because I never want to add a roll bar. The car is mostly street driven. If I dont have to deal with creaky noisy urethane bushings, that would make me happy.

Your welcome!
You can add some suspension parts to make the car drive nicer if you wish but none are a must have for your goals

Installed correctly they won't creak But those solid won't creak but they will make your old car rattle
