Suspension/Steering / Re: Advice on wheels.
If you are changing wheels why not bite the bullet and got to five lug and upgrade to the SN95 brakes?  Your world of wheel options really opens up and the SN95 brakes stop the car so much better, are easier to service, and the rotors are lots cheaper.
General Fox T-Bird/Cougar Discussion / Re: I made a Doug DeMuro style review video of the 87-88 Turbo Coupe
Great video!!  I miss my 85 TC just for the turbo spool.

Just a quick note, the Fox platform in the Mustangs ran from 77-93 with the SN95 platform starting in 1995 which ran through 2004 giving way to the S197 platform.

Also, The front LCAs on the 87-88 T-Birds/Cougars are 14" long which is the same as the 95-04 Mustang front LCAs while the 83-86 Birds/Cougars have the 12.75" long front LCA's which are the same as the 79-93 Fox Mustangs/Capris.  Call Maximum Motorsports and they will verify this. The 84-86 Mustang SVO utilized the same front LCA's as the 82-83 Lincoln Continental which are entirely different even though they are 14" long.  They have a deeper spring pocket, ball joint is raised, sway bar connection point is moved, and a non-serviceable large diameter ball joint. This LCA requires a longer spring due to the deeper spring pocket and the ball joint will not fit a Fox or SN95 spindle.  In general they are impossible to find but I thought it would be worth mentioning.
User Rides / Re: 84 Tbird project
So on the 73mm piston front brake personal opinion and experience is to run away from this "upgrade".  This was done on the SVO Mustangs as well as the Lincoln Mark VII's.  You will need a different MC in that these calipers require a 1-1/8" bore MC and will also require some kind of manual proportioning valve to tune the brake bias.  For all of the cost, effort, and time it is simply not worth the minimal gain over the 60mm stock 87-93 5.0 caliper.  You can buy really good brake pads and gain more braking for the $$$ that way than going the 73mm swap.

Save your $$$ and when you can afford it switch to 5 lug via a 94-98 V6/GT swap utilizing 99-2004 V6/GT front calipers.  The gains here are as follows:
Rear disc brakes
Larger front rotors and twin 44mm piston front calipers
The 94-98 V6 and GT rear axles are the exact same axles and will fit your existing 8.8 housing.
Rotor, caliper, and brake pad selection is excellent vs. the Fox garbage
Wheel selection is light years ahead of the Fox vintage stuff
The front wheel bearing hub assembly allow you to swap rotors and not have to mess with the bearings.
If you are willing you can swap the ABS from the Mustang over to your car.  I did it on my '93 Coupe and what a difference letting the ABS modulate the brakes in a panic stop versus "I can out brake and ABS system with my foot"...bullshit.

There are several write ups on the SN95 brake swap on here so do a little research.  You can have decent brakes with the 11" Fox front rotors and drum brakes out back but if you swap over to the SN95 gear you will notice a HUGE braking improvement.  There is physically no way to make a Fox brake system out perform the SN95 brakes, period.
Engine Swapping / Re: My 427W swap into my Cougar
Engine looks great! What trans are you using and assuming running it through an 8.8 rear?  I seriously thought about a stroker kit but I had a 351W crank from an SVO block for free that another guy was not going to use so that made my build a lot cheaper to go stock stroke and a 0.030" overbore.

Please post back up as you learn the Holly software.  We are going to build a 351W stoker for my dad's project and he wants to go injected by my experience is leading me towards a factory style Fox Mustang injection setup only with the Ford Mustang 8693 MegaSquirt Gen2 Plug and Play with a Painless EFI harness.

Again, that is one sexy motor!!

I have not verified these numbers but this list has been on the Mustang board for years and as far as I know it has been vetted.  Would have been great to also have had the new and uninstalled length so you could make a comparison but this is a lot of good info.
Suspension/Steering / Re: OK Guys, School me on SN95 front brake swap
The 96-2004 spindles will work but you have to be ready to deal with the possibility of bump steer and the additional space they move the front wheels outward.

With that being said the general rule of thumb is to run the 94-95 spindles on a stock k-member car and the 96+ on tubular k-member cars as most of them are designed for the 96+ spindle geometry.  I know the Maximum Motorsports and Griggs Racing units are designed on the 96+ spindles as I have them both. If you are going to run a tubular k-member call the manufacturer and see what they recommend.

I did run the 96+ spindles on my Mustang for several years with the stock k-member and stock LCA’s but I did run a bump steer kit.
Suspension/Steering / Re: Actual sweet spot on shocks/struts?
This is not on a Fox car but on my ‘70 F100 the QA-1’s have 6” of travel on the rear four link setup. The length of the shock from mounting point to mounting point at 3” of travel is 12”. I made a fixed tube steel jig that was 12” from center to center and installed the four link on that bases per the four link instructions. This allows 3” of compression and rebound from static ride height.

My guess is most dampers would want to be setup the same way.
Suspension/Steering / Re: Upr shock brackets
Shocks and struts for the '87-'88 Fox Thunderbird TC (same brakes as the '93 Cobra thus shock & strut mounting is the same) is now very limited in manufacturing brands and KYB seems to be the better performance (I use that word lightly here) of the two.  So I went out to O'Reilly Auto Parts and pulled this data and in the past I have found their data to be pretty reliable:

Data on the 1988 TC Dampers:
Excel-G Strut (P/N 235008):                           
Compressed Length is 13.5625"
Extended Length is 20.5625"

Excel Gas-A-Just Shock (P/N KG5556):
Compressed Length is 14.000"
Extended Length is 23.250"

Data on the 1993 Mustang Cobra Dampers:
Excel-G Strut (P/N 235009):                           
Compressed Length is 13.1875"
Extended Length is 19.250"

Excel Gas-A-Just Shock (P/N KG5551):
Compressed Length is 12.625"
Extended Length is 20.6875"

From the data above the dimensional differences are as follows:
Extended Height - 20.5625" (TC) vs. 19.250" (Cobra) for a difference of 1.3125"
Compressed Height -  13.5625" (TC) vs. 13.1875" (Cobra) for a difference of 0.375"
Travel - 7" (TC) vs. 6.0625" (Cobra) for a difference of 0.9375"

Extended Height - 23.250 (TC) vs. 20.6875" (Cobra) for a difference of 2.5625"
Compressed Height -  14.000" (TC) vs. 12.625" (Cobra) for a difference of 1.375"
Travel - 9.25" (TC) vs. 8.0625" (Cobra) for a difference of 1.1875"

So they make the KYB AGX struts and shocks as well as the KYB Excel-G shock for the Mustang but I wanted a direct comparison from the Bird to the Mustang so I did not list those lengths.  They are a little different but they are expecting a lowered car i.e. performance based.

You can see that the TC shock is 2.5625" longer when extended and 1.375" longer when compressed and has 1.1875" more travel than the Cobra shock.  This of course is just the one brand and model of damper and the aftermarket manufacturers will vary from OEM in lengths.  This is due to if they already have a shock that is within 0.25" one way or another they are going to use it and just revalve or at least that is what I have been told.

No real conclusion on my end as to how far up you have to move the Mustang shock to get into the "sweet spot" but I do not profess to be a suspension guru and will leave that to Chuck.  Maybe he can explain how he came up with the 3" as I am curious.
Suspension/Steering / Re: OK Guys, School me on SN95 front brake swap
Sooooo do a search and all kinds of good stuff comes up but basically the swap is identical to a Fox Mustang swap to an SN95 front set up.  This one is pretty complete:

I believe it is the Mach 1 springs but hit Vinnie up or do a search on springs and then user name Vinnie and you should find a couple threads on this.  I have full coil overs so not much help unless you want to go that route.  And please don't cheap out on the caster/camber plates and buy the Maximum Motorsport units.
