Arning drop

I would like to do the drop on my 66 coupe. I have Granada spindles. Can it be done with the Granada
spindles ? Also can I use the Daze alignment specs ? Oh yea, warmed up 351W, T-5 and 3:55 traction lock 8".

Re: Arning drop

I can tell you from direct experience with that same combination that you really need to consider getting some spindles with stock 65/66 geometry.  You will never get a satisfactory result with incorrect ackerman angle.

Shelby used specs of 2.5 to 3 degrees positive caster. zero camber and 1/8 toe in for street driven cars with the Shelby drop.

I found that the Granada spindles gave the least trouble when they were toed OUT 1/16" or so.  You will experience front tire squeal on acceleration otherwise.  And be careful if there is a rise in the road coming up.

Re: Arning drop

Gotta second what Steve says, the stock geometry is really good with the Shelby drop. The basic early Mustang front end had great potential, far better than any late model strut junk! With the shelby drop, the camber curve is pretty good for all but the most agressive street driven tires. I would still have the stock stuff except I could not resist getting rid of the shock towers so I can run some real headers. I put in the Mustang II stuff with custom A-arms to get a more agressive camber curve for my track tires. I run as much as 5 degrees negative camber at rest. This sucker will go around corners. When I am not going to the track though, I run less than 1 degree of static camber and make sure both sides are the same. I run 8 degrees of positive caster. On the stock stuff, I always set as much positive caster as I could get on the side with the least possible and made sure both sides were the same. Bottom line is the basic stock stuff in good shape with the drop is GOOD stuff!

Re: Arning drop

CSRP makes Granada spindles with the steering arms in the correct position for the 65/66.  I just installed them on mine last year.

How do you manage 8 degrees?  I'm not at that stage of assy yet, but I'm shooting for 5 degrees on my 66, but don't really know if it's possible.  I've moved the shafts in the uppers one turn, and will try to locate the Arning drop holes back a bit if I can be sure to get the nuts on the back, but I don't want to force the lower arms forward.

 I am running 5 degrees positive caster on my 66 now. I have a set of Glen's adjustable strut rods.  I have three degrees from shimming, plus another two by shortening the LCA.  If you do this, be sure to tack weld the LCA inner bushing so it cannot slide out of the LCA.  Mine started moving, so I recentered them and added a very small tack weld just to keep them from sliding.  (I now have stock 66 V8 spindles).  I noted very little inprovement, if any from the extra caster, so when I rebuild the front end, I am going back to about 3-4 degrees caster to avoid the stress placed on the LCA bushing.  If you get all the adjustment on the UCA, the LCA bushing will not be stressed.

Re: Arning drop

To get 8 degrees I have the Mustang II front type Heidts cross member with custom a-arms. The angle is built in the the arms. I changed both the lower and the upper so my wheel is still in the middle of the wheel well. Since I run the Hoosier DOT raidials at the track, the higher angles help them work across the entire tread. I do set-up with a pyrometer to get constant temp across the tire.

Re: Arning drop

I'm building a '67 coupe for my son and have been considering the granada spindle and brake package with the arning drop any suggestions pro or con. Would like to keep the '67 styled steel wheels if I could.

See posts two and five.
Makes you wonder though......if your son starts off driving the 67 with the Granada "handicap"(so to speak) to him......that will be how a Mustang is suppose to steer. Now, if he's driven other vintage Mustangs and recognizes how thet are suppose to steer then going to the Granada spindled Mustang may feel strange. Just thinking out loud.......

Re: Arning drop

I'm starting to lean toward stock 67 set up using Drake caliper brackets and reman parts seems cheaper than a lot of those kits.

Re: Arning drop

I just had my coupe set at +5.5 degrees caster, -0.6 degrees camber and between 1/16" and 1/8" toe. Fixed my wandering problems on the freeway and feels solid!  I got these setting with all shims. How much extra tire wear will I have verses 0 degrees camber?

 67-73 Mustangs and Granada spindles have the same geometry, so a 67 will drive like it should with Granada spindles on it.  You will have an issue getting those stock 67 SS wheels on it though.  See my Granada brake page for requirements.  Basically you have to have the "snout" of the rotor around the outer bearing turned down to same dimensions as the stock 67 hub.  Then use longer studs and a 1/4" spacer.  Might have to grind a little on the calipers, but it will work.  I have done it before.

Re: Arning drop

I too can warn of the hazards of combining the Granada spindles with a lowered upper control arm on the 65-66 cars. 

I went a little further than the Arning drop, using wedges to angle the ball joints correctly.  Like Steve said, watch out for that rise in the road at speed.  Scared me to death the first time I went over a rise at about 50-60 mph.....I kid you not, I had NO IDEA which way the car was going.  It just wanted to dart somewhere other than straight.

This is not an issue with the later cars, but it can be a terrible combination on the 65-66 cars.
