jeffmerkur Posted January 27, 2014 Share Posted January 27, 2014 I was wondering how you guys would go about getting a Fox Stang or SN-95 to the 76.5" track width if the rule was changed? I got myself a New Edge rear and some H&R 40mm spacers. Those along with my 17"x9" Terminator wheels have me at a little over 74". H&R does make 65mm spacers witch would get me there if I can find someone who sells them. On the front I'm welding on rod ends to the MM SN-95 control arms. I should be able to make up the difference with spacers? I don't have the front end together right now so I can't give #'s for the front. I'm still building the car. Has I have said before I'm not in AI yet but that's my goal. Thanks for the impute Quote Link to comment Share on other sites More sharing options...
rpoz27 Posted January 27, 2014 Share Posted January 27, 2014 Is this another red herring? 76.5"? Where are you getting this idea? Quote Link to comment Share on other sites More sharing options...
jeffmerkur Posted January 27, 2014 Author Share Posted January 27, 2014 Is this another red herring? 76.5"? Where are you getting this idea? Well, its not and I'm serious. I guess I will come out and say it. I am building a 88 Thunderbird Turbo Coupe. I have confirmation that my car wouldn't fall under the Fox Stang track width rule. Its not on the list in the rules and would fall under " other" and could be made to the 76.5" max. I'm thinking something close to 76" would be my goal.

jeffmerkur Posted January 27, 2014 Author Share Posted January 27, 2014 I'm not trying to get flamed or cause trouble. I run in HPDE 3 and work the grid at NASA events. My plan is to run TT this year with my 95 Cobra and have the bird ready to go the year after for AI, hopefully. I'm trying to build the car to max with in the rules and was looking for some impute.

Arca_ex Posted January 27, 2014 Share Posted January 27, 2014 I think the most important question is why do you want that much track width? Quote Link to comment Share on other sites More sharing options...
edhunter Posted January 27, 2014 Share Posted January 27, 2014 I stretched my AI fox to 74.5" a couple years ago. Did the same as you, welded threaded adapters in the lower control arms, and used rod ends to gain the width. This was along with building a SLA. On the rear I used 2" (I think) bolt on spacers on SN95 axles... Quote Link to comment Share on other sites More sharing options...

I'm just trying to build the best handling car I can. I hope that when my skills catch up to the car that I might be able to hang with the 197's? That's the goal.

SNAKBITN Posted January 27, 2014 Share Posted January 27, 2014 In a sn95 I used the Griggs sla with 1/2'' wheel spacers to get to 74 1/2'' and a rearend from a 2000 gt which is 1 1/2'' longer with 3/4'' spacers.I wouldn't sweat the 197's anymore,it's the new s550 that I'd be looking at.

I have the same rear, it was a full 2 inches wider then the stock 8.8. I had to get 40mm(1.575") spacers to get to a 74" track width. What wheels and offset are you running?

SNAKBITN Posted January 27, 2014 Share Posted January 27, 2014 Enkei with 22mm offset I think.74''s wide also. Quote Link to comment Share on other sites More sharing options...
wstukas Posted January 27, 2014 Share Posted January 27, 2014 Not a fox, but on my 93 Camaro I built a custom SLA up front with 2" longer lower control arms, and run 2.25" bolt on wheel spacers in the rear to get to just under 76.5" I also widened the body in order to keep the tires under the fenders. The added frontal area of the body cost nearly 5 mph on the back stretch at Road Atlanta. Net gain of the both the added trackwidth and SLA was worth ~1.5 seconds a lap at Road Atl, even with the lower straight line speeds. I attribute most of the gains to the SLA though.

This is why I posted this here. You guys know what your talking about. I hadn't considered this. At 74" I have to do very little to the Thunderbird to make that work. Some 1.5" bolt on flares is all I would need. Going to 76.5" will take more work. I hadn't considered the added drag of making the car wider slowing me down. I have to weigh the pros and cons. At VIR on the back straight sounds like its going to hurt? At Summit and the rest of VIR it would probably be a net gain? Thanks for the help guys.
