Front QA-1 Coil-overs

Postby Skeezix » Wed Jul 25, 2012 9:51 pm

This particular post is on behalf of a car club member,
so bear with me on my grasp of his car's details & scenario.

455 1964 Cutlass, headers, Edelbrock intake, 4-speed, approx. 3400 lbs.

He bought the upper/lower Global West (Delrin) front control arms
with the single-adjustable QA-1 coilovers. Stock-height control arms.
Kit came with 450# springs, but was too low re: stock ride height.

Now, has the 550#s in & the battery in the trunk, but is still a bit
"nose-down". Are guys over-estimating and/or have incorrect
expectations for the front-coilovers' up/down adjustability re: height?

His alignment guy, who says he has a similar QA-1 front coilover
set-up in his car, has told him there is a factory-specified (QA-1)
range of adjustment, and the maximum height obtainable within
that range (essentially the middle 1/3 of the threaded-span) has
been reached.

The alignment guy he "could" run them up to the last thread and
potentially add possibly add another inch to the ride height, but
he refuses to do it, as it supposedly is beyond QA-1's parameters
and he says he's not wanting to be responsible for parts breakage
or worst case, a wreck.

The owner, however, feels "the threads are there to
be used" & is at a loss what-to-do, as 550#s are the max. from QA-1

Issues with QA-1 Front Coil-over adjustability is out of my arena of experience,
so I'll just pass along your first-hand suggestions. Thanks once again!

What is the diameter of the springs?If the load /force is pushing the adjuster in to the threads I would run them on the last threads ,if the load is pushing away fom the threads I wouldn't.

I will have him provide that measurement of the QA-1 front springs.

The thought has occurred to several that GW may have accidentally shipped their 2" drop control arms.

Thanks very much, RCJ!

We use 2 5/8 diameter coil over springs in oval track,you can get a lot stiffer spring in that diameter.To low ride is a good justification for aluminum heads to me.
