Default QA-1 coil over conversion

Has anyone seen or used the QA-1 68-82 fronycoil over conversion. It looks like it uses the top spring pocket and then has ride height control on the shock, also has anyone used QA-1 shocks any recomendations on spring rates and shock type

Are you talking about the thru coilover system from Jim Meyers or the semi coilover from Speeddirect?


The Jim Meyers system uses custom made upper and lower a-arms.

I put QA1 double adjustable shocks in my vette but they are not coil overs. I like the shocks a lot. There is nothing like having adjustable rebound and compression damping to dial in your suspension and control the springs that you have. They are relatively expensive but certainly beneficial.

Which ones did you use? What height? I see Jegs sells them but for some reason the Camaro shocks are shorter? I thought that was weird.

Are you running stock springs?

Thanks,

Pete

Default I have been looking at these too...

On page 9 the QA1 Pro Coil System (GM Front Coilover Conversion) for the 63 thru 82 Corvette smallblock are listed as part numbers DGMP44 and GMP44.
The D denotes Double Adjustable.

The bigblock numbers are DGMP43 and GMP43.

I'm running the front semi coilover kit. Works great and turns flat. The bottom mount bothers a lot of people, but I haven't seen any signs of cracks or bending. With the LS1 in there, adjustablility is limited. My spanners are only two turns from the bottom and limits me from putting the car down in the weeds.

See pic below for stance.

I'm one of the people greatly boothered by the lower mount! I am reinforcing a set of lower A-arms right now to install these parts on my LT-1 Vette right now. I wouldn't trust the lower shock asorber mount to carry the weight of the Vette for a long period of time. In the short term it will work but, for 10K miles or more I think you will see failures in the thin section of control arm being asked to do something GM never intended it to do.

I agree, maybe a round 1/4" disk welded in would help. If I ran a big block it would scare the hell out of me to trust that thin peice of metal.

stingry, I bought mine through Summit but I called QA1 on the phone first to get the correct part numbers. My shocks are not for a coil over setup. They are double adjustable and fit with the original setup. If this is what you are interested in, just call QA1 and do as I did. Summit does not stock the shocks but they can have them drop shipped to you.

Same kits. Semi-coilovers just with the standard Corvette store markup.

Guys, listen to him..he's right. The stock arm is way too flimsy to hold all that weight, as for big block or small block like Budman says, it really doesn't make a whole lot of difference, static load isn't that much of a problem, it's dynamic loads, the loads on suspension members can be enormous, remember that the faster the suspension has to react tha greater the load (imagine driving though a big pothole) and this is many times larger than just the static vehicle weight on the arm. Eitehr plate up the lower arm or use some kind of disc to spread the load over a larger area.

Makes sense.

Bend a coat hanger back and forth enough times and voila...
Instead of the load being spread out over a larger area you effectively have two points of contact where the shock bolts to the lower arm.
Thanks for your input guys. Helped me make up my mind.
