I am getting ready to install 15 X 10 Race Star wheels on the back of my S197 with Mickey Thompson ET Street Radials 325/50/15’s. To accommodate the rims and tires I have to make a few changes:

1. Longer wheel studs (safety).
2. Fabricate new Jounce Bumper plates for the axle housing that relocates the Jounce Bumpers to under the frame rails (maintain Jounce Bumper functionality)
3. Trim the bottom off of the OEM sway bar mounting points and install a Sway Bar relocation kit. (clearance for the 15” rims)
4. Remove the Bump Stop Bracket on the frame rail (tire clearance)

I covered the long wheel studs in this thread: https://themustangsource.com/f730/ar...nstall-504930/

In this thread I will cover the new Jounce Bumper Plates and trimming the Sway Bar mounts and installing the relocation kit.

A before picture of the driver’s side OEM Jounce Bumper:

Finished pictures of the Jounce Bumper plates, installed relocated Sway Bar and removal of the frame rail Bump Stop Bracket to follow.

 

This car is starting to look like one of those NASA projects ,,lol,,,looks good thoe ,

 

Thanks Rick. I am patiently waiting for delivery of my Race Stars and Tires (front tires are back ordered). Next up will be installation of a BMR Suspensions Xtreme Anti-Roll Bar. Just have to get my youngest daughters boyfriend to drop by with his MIG Welder.

 

Finally finished painting and installing the relocation plates with FRPP Jounce Bumpers (part number M-5570-A):

 

Started working on removing the Bump Stop brackets on the frame rails for tire clearance.

The bracket to be removed on each side:



Undercoating removed to expose the four spot welds:



Spot welds cut with a 5/16" spot weld cutter and 3/8" drill:



Spot welds broken loose thanks to a little persuasion with a hammer and chisel:



Next step is to cut the bottom of the Bump Stop Bracket as close to the frame rail as possible. I am still pondering what the best tool would be to make the cut without "hacking up" my baby too much. Any ideas?

 

Have the bump stop brackets removed from both side now and spot weld residuals cleaned up.



Next up is some paint and a little undercoating.

Then I will be ready for the MT and Race Stars!!!!!

 

Undercoating applied. All done this mod. Wheels and tries have shipped and should be here by end of day Wednesday the 14th.

Next mod is to install a BMR Suspensions Extreme Anti-Roll bar.

 

 

Rick, thanks!

Rims (with valve stem TPMS), tires and lug nuts finally here. Installed pictures to follow:

 

Cool, by any chance do you know what make and model of your stem mounted TPMS units are? I want to make the jump to 20" Forgestars and its a bit cheaper to run the stem mounted sensors rather than getting a second set of band mounted sensors.


Also, not interested in a sensor bomb (a search of my posts on the subject will show I'm completely adverse to disabling the TPMS system).

 

Sensors are made by ORO-TEK, I got them from American Muscle.

I just mounted the tires on the car last night and have not completed TPMS Sensor Training. I therefore can not recommend them yet, but I have absolutely no reason to think they will not work properly.

 

Very nice. Hope to see it at an event soon.

 

Race Stars and MT's finally on the car. She's out of the garage for the first time since last November. Just completed the BMR Suspensions Xtreme Anti-Roll Bar install as well. (please ignore the garbage in the first pic)!

 

I have stock lugs, but I was wondering if you or anyone has tips on installing these wheels? I just don't feel confident that they are centered..

 

I would not chance Race Star wheels with OEM Length studs. Take a look in this thread:

https://themustangsource.com/f730/ar...nstall-504930/

In one of the pictures you will see that with the OEM stud none of the lug nut head will be engaged.

I agree multi-lug rims are tricky to install and take time to get the washers located correctly. You need to use the hub-centric-rings that locate the rims and install one washer nut combination at a time with the lug you are working on at the 6 o'clock position. The weight of the offset will properly position the washer. It is also my strong belief that using an impact wrench is a no no.

 

Im using there lug nuts,, but my question is. After the first one positioned at 6 do I tighten it up or keep loose when I move to next one.

 

Needs to be tightened enough to prevent the washer from moving. Also suggest you look at McGard washers and lug nuts, part number 63000. They are not as soft as the Race Star versions.
