Re: Custom made spindles for coil-overs? Reply #15 – January 21, 2005, 02:01:22 PM Quote from: cougarmanThey are from Granatelli motorsport, iirc, they had about 3-4 inches of adjustment the springs were 500lbs. It's been awhile since I had them, traded them for a set of Cobra r's and some air tools. If I find any more info I'll post it. 500# springs on a coil-over?!?!? That is WAY high for a street car, and very few, if any off the shelf struts will be able to cope w/ that wheel rate. You sure about that number? Quote Selected

Re: Custom made spindles for coil-overs? Reply #18 – January 21, 2005, 03:25:40 PM With 500# springs I can see why...oof!I can't remember what the exact ratio is on the Foxes, but that is almost like a 1000# spring in the stock location. Quote Selected

Re: Custom made spindles for coil-overs? Reply #20 – January 22, 2005, 09:07:38 AM Granetelli, I'm pretty sure thats my brand! And upon seeing the pic, that's exactly what I had. Springs look like pretty much the same length too. But, when I measure mine, measure just the spring, not as an assembled kit, right?Does anyone have pics of this kit on the car, wheel off? Also, what tires sizes are all of you with 17x9's running and about how much clearance do you have between spring and tire? Thanks Quote Selected
Re: Custom made spindles for coil-overs? Reply #21 – January 22, 2005, 09:20:45 AM Right, you just measure the free-length of the spring with no load. Quote Selected
Re: Custom made spindles for coil-overs? Reply #22 – January 22, 2005, 08:40:57 PM Generally, the springs supplied with coil-overs are short enough that the lower spring perch is above the top of the front tire. You can just buy shorter springs in the correct diameter/length/rate to get the lower perch far enough up the strut to not cause interference with the tire/wheel. By the way, what backspacing are you running on the r's on the front?Holy God, 500lb/in coil-overs? That's equivalent to 1800lb/in springs in the standard location! For future refefence, the motion ratios for fox cars are:Front:conventional springs: .25coil-overs: .9Rear:conventional springs: .5coil-overs: .95To calclulate wheel rate, multiply your spring rate by theses numbers.

Re: Custom made spindles for coil-overs? Reply #23 – January 23, 2005, 09:31:27 AM I'm using a 10" 375lb Hypercoil spring on my TBird. This is with Koni double adjustable struts. The ride is firm and controlled, but not harsh. Quote Selected
Re: Custom made spindles for coil-overs? Reply #24 – January 24, 2005, 12:58:44 AM I think the backspacing on my wheels is 5.95 inches. They are the proper wheels for a fox car... Quote Selected
Re: Custom made spindles for coil-overs? Reply #25 – January 26, 2005, 02:27:32 AM One other thing I just thought of...When I put the coil-overs in, I modified the stock TC caster/camber plates (or whatever the stock pieces would be called) to work with the coil-overs. In the end, the top of the strut was still at the same location as it was before the coil-overs or before the plate modification. So I figured this should be fine, but maybe not...?? And if I was to use different plates, which ones should I use (since the holes arent reversed on one side like on a mustang)? Quote Selected
Re: Custom made spindles for coil-overs? Reply #26 – January 26, 2005, 07:11:28 AM The c/c plates (or the stock upper strut mounts) will have no effect on the spacing between the strut body and the wheel/tire. It is a fixed mounting at the spindle and the distance will always be constant regardless of how much you mive the upper mount around.. Quote Selected
Re: Custom made spindles for coil-overs? Reply #27 – January 26, 2005, 02:02:02 PM Thanks Chuck, I understand that of course. I was thinking vertical changes though. Maybe a plate other than the TC plate would cause the strut to mount higher in the engine compartment, raising the splindle and therefore changing the angle of the entire assembly? Quote Selected
Re: Custom made spindles for coil-overs? Reply #28 – January 26, 2005, 02:55:08 PM Nope..it will still be the same distance between the strut and the wheel/tire no matter how high you mount it. It is a fixed mounting point at the spindle....I'm still going to guess your primary problem is that the springs are too long. Shooting some pics would help us out greatly.... Quote Selected
Re: Custom made spindles for coil-overs? Reply #29 – January 26, 2005, 03:40:22 PM Ok, thanks....I'm working on measurement and pics. The car and kit are in WI at my parents house. I'm in CA so it's kinda tough! Quote Selected
