Its all about the stance on my Fox Cobra
 

I am in the process of building a 93 Cobra which already consists of a minitub with 345/30/18's in the rear, as well as, plans to install a Twin Turbo GT500 5.4L motor. I had previously ran the stang with 275/35/18's on the front, but the backspacing and tire width put the tire at the edge of the wheel well. My new rims I am using have 1/2" more backspacing, but I was already within millimeters of rubbing the struts.

I am considering a conversion to an IFS in order to accomplish a fully adjustable ride height, the widest tires possible, and nicely tucked under the chassis. I like the art morrison IFS MII and CACHASSISWORKS as well. The hub to hub measurement is around 57" and the outside of the current frame rails are about 35".

I am looking for some advice. I have not seen anyone do such a modification on the Fox Mustang although plenty of classis stangs. My plan would be to chop out the current front frame rails (but retain current radiator support) and then weld in the whole new package.

Is there a better approach I should consider?

The whole build is documented at http://www.theturboforums.com/smf/in...?topic=92581.0

Thanks,

Michael

Welcome, Michael. That looks kick ass!! Definitely keep us up to date on the project.

I see you're in Atlanta, and since you're into Mustangs, do you know McBride?

Wow - that's looks great. Can't wait to follow the progress.

thanks for the positive feedback. i am anxious to see the stance with the original cobra ground effects on and some fresh paint.

sorry XcYZ, don't know mcbride. i moved to atlanta 2 years ago and actually haven't spent much time out with any stang clubs or at the track given this project has been in process since the start of 07. just time to work on it a few weekends a month.

here is one that i was considering made by chris alston's chassis works. its a weld in piece available in several hub to hub lengths. i would weld it in place with some 2x4 frame rails that would replace the current frame rails from the firewall to the radiator support. am i missing something cause it seems very "doable" in my opinion yet i can't find another fox stang that has IFS?

The thought of running an Art Morrison IFS in a fox body had crossed my mind a time or two before. The Alston would be a similar setup. I don't see any reason why is can't be made to work. People do it all the time in older unibody Mustangs.

From a structural standpoint, you'll want to make sure that you have braced the front so that it is carrying the loads through the right points. I would think you would want some support bars to the firewall that tie into ???? Are you going to run a cage?

What are you going to run for rear suspension? Custom? Modified Stock?

This project has me really intrigued!

Later

It is very do able, the reason that most people don't do it is because the stock suspension is not that bad, when you compare it to older cars that had crap, those are the cars that everyone replaces everything.

i do have an 8-point cage i just finished. the rear is an 8.8 with modified internals. it has an auburn posi, 3.73's, 31 spline moser axles with 5 lug and stock cobra disk brake set up. in order to fit the 345/30s, i had to relocate where the lower control arms mounted to the axle tubes. cut off the factory mounts on the axle tubes, and put some custom brackets which were moved in about 4". i'm using tubular / spherical rod end upper and lower controls. the rear frame rails were cut out and re-routed to provide enough room, but they do tie back into the original frame rails in front and behind the rear end. its still basically a stock 4-link set up but now provides more clearance for the steam rollers.

i have everything on my site. here is a link to a vid i posted on my documented build on "theturboforums".

Nice project. Keep us up to date.:thumbsup:

have you tried griggs suspension? they claim you can use a 315 tire, would save you alot of work since its a bolt in.The stock mustang style suspension work very well with the right parts.

very interesting. i never saw this before. basically converts to an IFS without chopping the frame or shock towers. the link you provided lists for $550, but doesn't list what is included. I believe this may only be the coilover tower. i assume one would need the complete kit which lists for $2400 (http://www.griggsracing.com/product_...roducts_id=427) :

Tubular K Member
Bump Steer Kit
Aluminum Rack Bushings
MFA 2000 Series Front Control Arms
Urethane Control Arm Bushings
Camber Caster Plates
2.5 x 12 275# Springs
Front Coil-Over Kit
Koni Red Struts
Short Driving Link Set

is that the way you guys read it? Not a bad option which would allow me to avoid chopping out the current frame rails and shock towers. love the idea of the 315s, but gotta believe the steering would be limited as I would think they would rub the frame rails on street applications. could be wrong. i need to call griggs and find out.

thanks for bringing this option to my attention!!

thanks,
