MM Panhard Bar on 88 Tbird
#1

Did a search and couldn't find anything that addressed the question I have. I know there are a few forum members who have installed a Foxbody MM Panhard Hard bar on their tbirds. My question is what did you do with the passenger side shock mount? Right now, I'm running reinforced shock brackets from Heath for my coilover setup. After looking at the panhard bar shock mount, it looks like the shock bracket will be placed lower (mustang factory height?) than my current reinforced mount. I'm thinking that if I run a mustang lower shock mount on the passenger side I should be good to go as far as leveling out the shock mounting points on both sides. Thoughts?

Since you're running coil-overs, it shouldn't matter, as long as your suspension has enough droop and the shocks are long enough.

The stock TBird shocks are about 3" shorter than the Mustang ones, so if you're c/o set-up is sized for Mustang length, you'll want to make sure things are long enough to allow for that difference.

You may have to get creative and make some mods.

Thanks Chuck, did you mean to say that the mustang shocks are 3" shorter than the stock tbird shocks? Currently, I'm running the 79-04 Mustang Koni single adjustable struts in the rear with the maximum motorsports coilover kit. I had plenty of shock travel and even distance to play on ride height based the spring placement before I took it all apart.

I'm hoping to confirm with MM Tech today but I believe I should be good. Even with a slightly lower shock mounting point, I should have enough travel in the rear

I did mean to say that, because they are in fact 3" shorter, The main reason why I did the lower shock adapter brackets all those years ago. You mentioned using Heath's shock brackets, which are my old shock brackets, that raise the lower shock mounting point about 2-1/2" over the stock location.

I tried Mustang shocks on the back of TBirds (SVOs all the way to New Edge 99+ cars) and I had to compress the rear springs so much to even get the shocks installed (like had to have someone in the trunk to hold the car down...) Even with slightly shorter rear stock-style springs.

Coil over are a totally different story vs stock springs in this respect, but you're still using lower shock mounts that raise up the lower shock mount, if I read your post correctly.

You may be able to get enough travel and have your car at the ride height you want with the lower shock mount in the "Mustang" location, but you may need to raise things up with the current bracket you're using on the one side and modifying the other.

Thank you Chuck; that all makes sense. I actually just got off the phone with Mike over at MM and he explained that using the lower “mustang” shock mount on the rear end will not allow enough travel due to the heightened shock tower points in the Thunderbird.

To remedy this, my game plan is to use your/heath’s shock mount on the passenger side like I was previously and modifying the driver side to work with the MM panhard bar mount. I’m going to cut up the driver side shock mount and weld it into the panhard bar mount so I can keep the higher bottom mounting points for my coilovers. Unfortunately, us Thunderbird people don’t have an out of box solution for this yet so creative solutions are needed. I’ll be sure to take a bunch of pictures and post my results when completed. Hopefully others going down this path will find it helpful
