Title: Foxbody Coupe Aero.
Post by: 23_hellfox_23 on June 04, 2013, 12:43:15 PM
I will be building a foxbody coupe for standing mile and I'm curious if anyone else is doing so and what kind of aero they are using.
My car will be powered by an LS power plant with a T56, 8.8 rear end with 3.27 gears, full tubular suspension, chromoly cage, basically my plan is a tin can on wheels making around 600-650rwhp if I stay N/A.
The aero I already have planned is a belly pan (just need to figure out what to make it from), I will have a wing made that will be fully adjustable and possibly a front splitter, along with removing the mirrors and getting 1 piece headlights but I can't think of anything else I may need.
My primary use for the car will be road racing, and (odd is it may sound) the car will be doing some minor daily driving.
Purely when I want to look cool coming to work in my "racecar" but other than that I will be doing road racing (which will get a better gear ratio of probably 3.73s or 3.90s).
Does anyone have any advice or pointers to help this project along?

All advice criticism etc is welcomed.

Thanks, Cory.

Hmmm . . . Where are you racing, and do you have their rule book? 

This will lead you to the class you can run in.

I'm not racing just yet.
And I won't be in any certain class so that does not matter to me.
(probably unlimited class)

The question is, at which mile event are you planning to run your car? You will need a rule book for that venue so you can build your car to the clas rules you what to run in.

Texas Miles is my plan.
I wasn't aware of anything class wise.
I'm just looking to go out and go fast not compete for anything exactly.

I mean if I have to go by a certain class it would be great it someone could get me some info on a class close to my description.
I'm going to make this car an all around car.
Where I can semi daily drive, road race, standing mile, and some car shows.
I know that probably is alot to ask but that's what I'd like.

All events have class breaks, even for Time Only (TO) (Just for fun) there are guidelines (rules) that the cars have to meet before they are allowed to run. Certain classes can only run up to certain speeds. I would suggest checking out the Texas Mile website carefully. Then get a rule book and read it carefully.

Getting a rule book would be alot easier than trying to tell you what is allowed and what is not. Read the book then ask the questions about items that you don't understand.

Completely understandable.
I have read the safety guide lines and the rules on speeds so I get that kind but I don't remember anything about class.
I will check into it and see what class then.
Thank you very much.

I have email mike with the Texas Mile committee, gave him info on my build and what I will be looking to accomplish will await his email back and hopefully that will tell me what class I will be in and if I'm lacking anything to get going in a certain direction.
Now when I road race I will be in an open class the "just for fun" but still rather competitive class so modifications are allowed all around.

Your on the right track, no pun intended. Lots of folks want to "just go out and have some fun" but safety is the key.

Although I understand why you say "build a street rod or a race car" I will have to say that I am trying to build a car.
So I would hope it can do all of it with a little change of rear end, aero, suspension and tune.
And a Foxbody is a mustang made from the year 1979-1993, the term foxbody is simply chassis designation.

Whew, I'm glad I am not the only one who did not know what a Foxbody coupe was. :-o

If you want to be competitive in road racing your LSR cage will be way too heavy.  You might have shed a lot of pounds elsewhere to make up for it. Tony

From what I read on Texas mile rules I will run a 1.5"x.120 cage and it only needs to be 4-6 point which I will run a 6 point.

I would think twice about running 200 with  4-6 point cage.  I don't know the Texas mile rules, but if they are based on SCTA rules you would have a tough time passing tech for 200 mph.  Start a build diary so we can follow the build.  Tony

Sounds to me like you would enjoy and fit into something like the Sandhills Challenge open road race in Nebraska. I have a pal that has done this and the Texas mile in a Vettte

I will be getting one under way.
I am just waiting on my motor/trans to get around to me.
I'm not just set to a 6 point I am just talking to a few people before I start on structure things like that.

Yep, What Tony said, Start a build diary w/photos, askquestions and read, read, read.

Glen, I too had to look it up. Apparently it the for the 1979 and newer era standard Mustang coupe. "Fox" platform. like generation for Chebbies.........JD

Well you are definitely looking at some cage work.  Roadracing the Fox body can be done depending on class with stock body but subframe connectors, caster/camber plates would be a minimum.  Next step up would be an 8 point cage and then you still have the stock Fox struts and not so great geometry.  Why not go with a Griggs setup and an LSR legal cage?  You'll be heavy for roadracing but the Griggs will give you the handling and not take away anything from the Salt performance. 

An LSR cage will be prohibitive for street use but that's probably not an issue for you.

BTW - I have an SSP Fox body going up for sale if you know anybody interested (Highway Patrol pursuit Mustang for all the non-Fordnatics).

I wouldn't build a car with anything less than a 1.75" x .134" cage... You can go 1.75" x .105" Chromeoly to save weight but 4-6pt
1.5" is generally what K, J, I class minimums are for ECTA events... we're talking 150mph (max) cars. You could do a bolt-in deal to
save weight while road racing and make it easier on the street... I believe Maximum Motorsports makes some bolt-in options for that
platform.

As for other safety stuff, 650rwhp in that car will make some speed... I'm guessing 175+... Which would require dual fire systems, a
parachute, racing seat, Hans device, etc. Those are some of the general ECTA requirements, not sure what Texas requires.
