Huge brake upgrade for S197 chassis

[steveespo]

Glad to hear El Jefe. I always run spacers with my Team Dynamics 18x10 or Boss 302S 19x10 wheels so didn't realize stock Boss wheels would need to be spaced out to clear. Also I run aftermarket braided brake hoses that have a round hose end so didn't have that issue either. Thanks for the update.

Finally got the calipers installed, ran into a couple issues though...

The (Dorman) GT500 brake lines I got weren't lining up straight where the banjo bolt attaches to the caliper. Had to slightly grind down the square area of the brake line so the banjo bolt lined up straight.

The other problem was my stock BOSS wheels didn't clear the calipers (just barely). Was making contact when i tried to spin the wheel once mounted. I double checked everything but still made contact at the top/bottom outer side of the caliper. Had no choice but install a 5/16" spacer in the meantime. Gonna try a 3mm and 5mm spacer to see which one sits closest without making contact.

Other than that the brakes work great! took it out for a drive and didn't have any issues. Could definitely feel the difference from high speed braking, bites harder with less effort

I can get Goodridge to make a S197 Hose with the S550 Fitting. This was one area where we were not sure. The S550 end has an offset banjo bolt hole, I believe the Shelby uses a more centered hole. Edited because I struggle with quotes...

Any updates from anyone else that has completed this upgrade? Curious if the stock S197 master cylinder is sufficient or if needs to be upgraded as well? everyone running stock rear brakes?

No info yet, but I just ordered Steve's "kit" yesterday. It was $1018 out the door. I still need to order pads, lines, fluid, and spacers. I might do the front upgrade in conjunction with an upgrade to the GT500 rear rotor. Otherwise, I have stock wheels, master cylinder, and ABS module. Right now the target is to do this around the first week of April. In my usual way, I will document the 'f out of everything. Lots of pictures.

What did we conclude wrt the best braided line option? Tim? The Goodridge sound promising.

Any hard data regarding stock wheel fitment? Will a 1/4" spacer work? Other sizes? Is there a recommended spacer brand or source?

Special recognition to Steve for this amazing find! I have avoided this site for a couple of years, because I knew it would cost me money if I ever peeked in here for a look. Well, it was this thread that drew me in like a moth to a flame. Thanks, Steve. I either love you or hate you.

I just installed this kit on the wifes car https://lmr.com/item/LRS-2120AK/Mustang-GT500-Front-Brake-Upgrade-Kit-05-14

Every was perfect and matched right cost a little more than Steve's kit.

@Jimmy Pribble welcome back. I thought I read the stock Boss wheels won't clear those brakes but hopefully a spacer is all that's needed.

Yeah, welcome back indeed! Glad you're still in your Boss, even if you don't want us to spend your mod money! >

Been driving around for a week with the new brakes and haven't encountered any issues regarding the master cylinder or Abs system, switched to a 5mm spacer and fits just right imo

Which wheels do you run with the big brakes?

 

[venom52]

I know the 19" SVE Drifts clear with no spacer

I have the stock black wheels.

Powder coated S550 6 pot calipers are going on shortly:

What side of the banjo block has to be shaved down? I'd like to do it before I pull everything apart.

Thanks

Very nice. Where did you get the Brembo stickers? Do you have a link?

Wow, that looks pretty damn bad ass....

Detectivecoating.com did my front calipers with the stickers but you can find the stickers on eBay for a few bucks.

 

[El_Jefe_302]

I cheaped out and sprayed them with a caliper paint and ebay stickers, They look good for now....

Awesome!!! Was it the side opposite the hose that needed to be ground down on the square block?

 

[El_Jefe_302]

Honestly can't remember haha! Pretty sure was the front side, opposite of the hose end. If u try to line up the holes u should see where it needs to be shaved a bit

The red calipers look great!

I hate to be a pedant, but can a mod put this thread under Brakes instead of Suspension? No wonder I cant ever find it without using the search. Thanks!

My parts start arriving today so photos and updates will be coming shortly.
