Stock UCA's and Shelby drop

[67topless]

Can you use the stock upper control arm and still do the Shelby drop?

yes

+1, no problems. Just if you are in there, consider replacing some of the front end stuff while you are at it (if its not current)

I actually just installed new coil springs - roller perches and the car is sitting higher than I want in the front. So I was thinking of incorporating the Shelby drop and then if needed cut the coil springs. I've put close to 100 miles on the front end since I changed out the coil springs last week... going to give them a couple of more weekends to settle before I start tweaking.

I just didn't know If there was going to be any binding if I dropped the UCA's an inch... all the marketing on the high end UCA's promote the re-alignment of the ball joint to eliminate binding. Is this just for track conditions?

You will not have any issues with the 1" drop.
I highly recommend this mod for anyone who wants to improve the handling of their Mustang.

Lowering the upper control arm more than 1" does require either aftermarket control arms or the negative wedge kit to prevent binding issues. For the most part, this is only needed for serious track users IMO.

remmeber that the GT-350's kept the stock mustang control arms with the 1" drop. no reason a stock mustang cant keep the stock arms either with the 1" drop.

while the control arm is out, are there any beneficial ways of modding it? Boxing it or something.

the upper control arm relocation will only drop the front end by 1/4 of an inch. I HIGHLY recommend it for anyone wanting better control over the car. If you look at the geometery, the 1 inch drop on the body side will only translate to about a 1/4 inch on the actual ride side. I replaced my springs with 1 inch drop springs and did the shebly drop and only got about 1/2 inch total drop from my worn out springs.

Sure, Opentracker (John) has an entire writeup on this.

I gotta disagree here. I did the A arm drop a week or so before I cut my springs and I measured a 3/4" drop at the fender for a 1" drop at the A-arm.

Did you re-use your stock spring perches? If so, I suspect the perches being stuck at an angle may have given you your results since the angle of the back of the stuck up perch WRT the ground is more horizontal. If you think about it, the spring perch mounting point on the stock control arm is around 2/3 of the way along the control arm toward the wheel. If you drop the mounting point of the arm 1", the actual relocation of the spring perch mounting point drops 1/3 this amount or so, since the ball joint remains at a constant height because of the spindle (actually the spindle may move in if you increase your camber, affecting the height a fraction of an inch).
Make sense?

Yes, I did reuse the spring perches, and no, they weren't stuck in any postion. I know you won't get a full 1", but I kept track of what I did get and it was 3/4".
