I have a full QA1 setup along with the 52722 GM street performance upper control arms on my 72 Monte Carlo and absolutely love it. I was wondering how do you go about replacing the bushings? I have one bushing that's kind of tweaked/out of place and want to replace it. A video would be helpful on this. Thanks!
Just did my front uppers on my chevelle with your street arms. Night and day difference. Doing the lowers next and putting your coil overs in all four corner. QA1 all around. Can't wait!
Love to hear it! Thank you for choosing QA1!
In the pro a arm the ball joint looks like a .9" tall joint most run .5" does this increase camber curve more with a .9" joint.
Thinking about installing coil overs with my stock control arms this year then swapping to tubular next year.
You can definitely do that! The coil-overs are a great first upgrade and good bang for your buck. Thanks for checking out our video! Give us a call if you have any questions. 952-985-5675
just got my uppers and lowers in crazy difference. definitely worth it
I have a 86 Buick regal grand national that does not go to the track, although it certainly could, which set up would be best?
I already have the rear converted to the dual adjustable coil overs and it’s noticeably improved ride in rear but my front is shot.
Is there a kit available for upper and lower arms with coil overs and are there different rated springs tension.
I’m basically looking for a street set up, no dragging
Thanks
Do the uppers work if you go to a taller spindle, not a drop spindle. Like a speedtech or cpp with corvette style hub? I want to lower my GTO with a full length coilover.
Hi there! I would recommend reaching out to our tech team for some recommendations! 952-985-5675
I have a 71 Nova LS with stock rebuilt suspension that is used only on the street, but I want a much better handling/riding car. I'm on the fence with just purchasing new a-arms and coil-overs or a new performance loaded subframe. What's the difference of installing a new performance subframe vs just adding new a-arms and coil-over to the original subframe? I have no plans to take it to the track just want it to handle like a newer car. Thanks for the videos and love your products!
I would say as long as your factory frame is still in good condition, upgrading your suspension would be just fine! All of our current builds are on their factory frame and have been holding up great! Night and day difference after installing our product.
Would those street control arms fit a 1983 cutlass supreme? The reason I ask is because I checked the fitment on your website and it says doesn’t fit
Apologies for the confusion on our website. For the street control arms you will want part numbers 52765 and 52764
From Australia here - is there a way I can get a hold of technical specs of a-arms and 4-link kits so I can get safety sign off and register my car?
Hi there! Thanks for reaching out and choosing QA1! Unfortunately due to the ever changing requirements in all the different countries we are unable to provide any certificates of conformity or material specs.
Can I run airbags with these?
Most airbags will have the same eyelet type mounting styles as a coil-over, so there shouldn't be any compatibility issue with mounting them to our control arms.
