SCCA F-Street Setup. What's Everyone Done so Far?

[Norm Peterson]

yeah, i really wish we had the 3.55 rear ends

Are you sure that'll eliminate most need for 3rd gear? IIRC, the hot tip with the MT-82 in the later-year S197s was 3.31 axle gears.

Who was running and doing well on 3.31s?

 

[Norm Peterson]

Pretty sure that's what Sam Strano was running before he jumped ship. Definitely what he was recommending.

every S197 that won in FS(tock) was on 3.31 - strano, daddio and burdette.
3.73 only became an option in 2013/2014 with the track pack.

I guess I was curious about street tires, not F Stock on Hoosiers.

Edit: 3.55s were option IIRC during those years before 3.73.

i was also on 3.31 in my '13 - but i didn't make it to nats in 2014 unfortunately (did win in crows and packwood, and *almost* beat coulson at the packwood pro, who went on to win AStock later that year - albeit in FStock), and then i got rear-ended and that's how i ended up where i am

that said, i felt i was on the right FD in my car.

not if you optioned the brembo pack (which we all did)
nm, i'm mis-remembering - you could option the 3.55 and 3.73 on the brembo - but there was no point, the 3.31 was perfect for gearing.

Ah.

Well this thread is unfortunately drifting farther and farther from being useful.

it would have been useful of the S550 also had these FD options - you'd all be on the 3.31
... having the boss 7500 limiter would also have been useful!

Is there a write-up available for the FS legal camber mod?

Pictures, etc?

 

[ABQautoxer]

It's in the factory service manual. Or you can search around for pics of that page. 2mm inboard on the upper bolt hole is what is allowed.

Thanks, I gathered that throughout my reading.

I'd feel more comfortable executing with some pictures for guidance.

 

[ABQautoxer]

Different application but exact same thing. 2mm allowance inboard:

I did it on two sets of struts (originals and donor set I put Konis in). It's not hard just time consuming and getting the bolts out the first time is really difficult without an air hammer.

 

[Competition Orange]

got it, that helps

So I'm assuming the front struts are removed for this?

I'm familiar with suspension swaps, did many on my Golf R. Haven't had much time to get the Mustang's wheels off yet, so a bit green on this car.

 

[ABQautoxer]

You don't have to remove the strut from the car (leaving the 3 upper nuts on). However that can make it more difficult depending on your technique. I did the first set on the car, the second set off. To get to it you need to remove the brake caliper and rotor (simple), but the two bolts that hold the hub to the strut are in there like no other I've ever dealt with before and talking to others that have done this mod seem to agree so be prepared when trying to just hammer those bolts out doesnt work like you'd expect. An air hammer spits it out in 2 seconds.
