On Maximum Motorsports Website, it says:
Warning: 1996-04 spindles & Stock pre-1996 K-members

Do not install a 1996-04 spindle on a 1979-93 or 1994-95 Mustang fitted with a stock-geometry k-member!

Doing so will significantly increase bumpsteer because...

* The steering arm on the 1996-04 spindle is about 1.02" (26mm) lower (relative to the rest of the spindle) than the steering arm of any 1979-95 spindle.
* The lower steering arm forces the outer tie-rod end to a lower position.
* That new position is far too low for the steering rack location of any 1979-95 Mustang, and radically changes the steering geometry.
* It is impossible to correct the geometry with a bumpsteer kit because the outer tie-rod end needs to be raised so much that it would have to occupy the same physical space as the steering arm.


Now i know a few guys on here have done it on a stock k-member, and although i may swap out the k-member when i do the motor, i plan on having the suspension and rear built before i replace my motor. I was wondering if some people could help me understand how i can install the 1997 Cobra w/ 13 inch brakes spindles i have on my fox body.

Also, was hoping someone could tell me what master cylinder would work BEST for a fox running 13 inch brakes up front and 97 cobra rear disk brakes and axle (11.5" i think) in the rear.

Thanks, i just want to get this done in the next few months and dont want to convert to 5 lug 4wd and end up with the car driving worse.

FYI: i plan on installing a Road and Track box from MaxMo.


Thanks

Get an Sn95 cobra master cylinder and brake booster. That's what comes in the cobra r brake conversion kit, which also uses the 11.65 rear and 13 inch front rotors. 96+ spindles have some hardware for ABS, which in turn makes the front wheel base 8mm wider each side for a total of 1.6mm wider front wheel base. The steering arm is different on the spindles and as MM says, it will make bumpsteer worse.

i am planning to do the same to my fox...i was givin spindles rotors calipers and the flex lines from a 02. now i read it might cause bump steer..what is bump steer. anyway to prevent it? like i said everything was free...should i install these spindles?
anyone here running 96 plus spindles on there fox with stock k member?

An discription of what bumpsteer is:
"Bump steer has nothing really to do with hitting a bump per se.

You say when you make turns, the car feels like it's rolling.
So, if you have mad bump steer... when your chassis transfers weight to the outside tire, your suspension on that side compresses which will make your wheel turn more than you input.
If your castor is wrong along with your ugly camber, that's going to make turning feel even worse. You could describe it as feeling like you're rolling into the turn or the tires are folding under during the turn.
I call it "pushing" through the turn, otherwise known as understeer."

"Is the toe setting changing as the suspension moves up and downover bumps, or with body roll while cornering.."

ok i bought a ranger rotor from 1986 to fit my 86 mustang....the diameter of the ranger rotor is 10 1/4 and on my mustang is 10 inch..now i did research and no where does it say this other then it will work because my rotor is like a 4cyl..do i use the mustang bearings??will that extra quarter inch not work?
