New Rear Leaf Springs in my 1966 Fastback

Автокөліктер мен көлік құралдары

Replacing the old, tired, stock rear leaf springs in my 1966 Fastback turned out to be more difficult than I thought it was going to be. The springs I install are designed to offer a 1 inch lowering over the stock springs.

    Truth be told, those were installed in November, hence the subtle beard on my face for No-Shave-November. It gets really cold here and I wanted to get a few things done before the cold snap. I'm working on two videos right now that have taken almost 2 weeks and I'm still not done, it's just too cold. Thankfully I'll get them done before I run out of preloaded content. :)

    Andy, Love the videos. I did the same with my 67 not to long ago and have replaced leafs in 3 classics and had to cut out both sides on all 6 leafs. I had best luck with the 6” Diablo blades. I just went with stock shocks when I replaced mine. I personally think the look is great and like others have said too low you may get some rub and I also think they will settle a little bit and bring it down slightly more over time. Once you drive a couple times I’d recommend snugging up all the nuts again. Looks great though, keep the videos coming!

    I just did this this weekend on my 68. Like yours the bolts were welded in. My dad used his acetylene torch to cut off the leaf springs. He cut on each side of it, then got out the rubber, then cut the bolt. It was messy and fiery but it worked. I used stocked height springs and went from 4 to 5 leafs with no drop as it's a convertible and I might have to use lowering blocks in the future.

Even if I did use the lift, it still wouldn't have put the car high enough in the air to really help. No big deal, I had it easy on my last Mustang, this time around I had to make up for it. :)

    When you post your link in the Vintage Mustang Restomods group I'll share a pic of the stance you're looking for. I had similar springs and a 1/2 lowering block. The stance was great but I went I different route. Too many speedbumps and the car ended up being way to low. I changed the entire set-up, I added a QP 9" Calvert springs, adjustable shocks, and Caltracks.

I'm trying to find the balance of sharing my content with enough people so they can easily find it and hope it helps them with their install or at the very least provides some info to the questions they have. I'm also trying to find the balance of posting on other sites but not too much where it seems like it's an attention grab. However, it would be great to see how your car sits now. Caltracks are on my list, they're just behind a lot of other parts I need first. :)

    I'll try and do an update video down the road to see how much the front and rear settle. Agreed, not using lowering blocks would be preferred as they introduce a larger moment in the mounting geometry, but sometimes the budget dictates the parts. If the Leafs settle enough I may be able to remove them as the car would sit where I want it at that point. I have some ideas of different suspension, but that's a ways down the road, I think this is a decent compromise until then.

    @@nathannelson7020 Haha, no problem! :) My guess is your worn out springs and 1" blocks put you just under "2 inches of lowering" when compared to brand new specs back in the 60's. If you were to install some reverse-eye springs that provide 2" of lowering, it may be too much and then you're stuck. The advantage of the mid-eye gives you and install 1" lowering, but you can go lower with blocks if you want. I prefer s slightly stiffer ride so when I take it through the windy roads I don't bottom out as easily and I get more of a "sport" feel. The 4.5 Leafs springs are definitely stiffer than the stock 4 Leafs, but not as harsh as the 5 (like my last car). I'd say they're more towards the 5 Leafs on stiffness, but a decent compromise for what I am looking for. I say all this in terms of budget. If I had more funds, I'd move to a coilover setup and explore a few additional suspension mods. But, like most of us, the dollar controls my build and I'm not willing to wait a year to save up for rear suspension while the rest of the car sits idle the whole time. :)

    Thanks! Yes, the car has settled a little bit since installing the rear leafs and front springs. I think if I could do it again, I would not cut as much of the coil springs as they're almost too low right now (not, but close). And I would have just gone with a 1/2" lowering block in the rear instead of the 1 inch block. I have since put the 1/2" blocks in place, but I would have liked to save a few bucks.

Just a heads up on the aluminum bushings, while they'll reduce some of the slop we get in our suspension, you'll definitely feel more of the vibration and harmonics (NVH) when driving. If this was a track only car, then you'd be fine, but it may begin to bother you on street driving. This gets compounded if your roads are as crappy as mine. 😄
