Advice on setup for street and track!

[GAR944]

Another question for the forums: If you could get a new 4x set of 305/30r19 Yokohama AD09 for $1100, or a new 4x set of 305/30r19 Kumho V730 for $1500 - which one would you get? To me the AD09 at $1100 seems like too good a value to pass up.

I'm all for a bargain, especially if you aren't competing, also given you are still playing with setups, keep some cash for another item. That could be sway bars if needed.
I did the same, grabbed a set of RS4's for playing to take the load off my CRS's for proper hot laps, i hate being beaten even if technically they have faster cars.

Bnight - I was actually looking at GLOC pads, but no where near as aggressive as your R18/R12 lol. As first I wanted RSL29 all around, for street and track but the price was a bit of a turnoff. Then I was thinking of GLOC R12 front and R10 rear, and was pleased at the price/value! But during a long converstation with Sam Strano, he steered me away from those and towards more expensive and higher quality Ferodo pads up front. He runs 3.12, and recommended them, but as a more cautious step, I opted for DSUNO. I already love ferodo pads and the DS2500, and feel they are the ultimate tweener pad for a mostly street driven and novice/intermediate track pad. Sam says run DSUNO front, and EBC blue in rear - says I can run them on street just fine. I'm cool with that, but I also was interested in running DS2500 front and rear for street, and then DSUNO front for track, keep the DS2500 in rear. This way I can again, satiate my OCD of having unified Ferodo pads all around, and also compound compatible front pad swap. I have not yet purchased my rear pads, but intend to very soon... advice would be appreciated if anyone would like to share! I also plan on purchasing these Powerstop EVO rear rotors, at the guidance of Sam again. Thanks for your feedback on springs and pads, Bnight.

I run DSUno/DS2500 (OEM rears) on the street and they are great not much more aggressive than the street ones nor any noise No reason to change front pads it get's annoying very quick. I think RSL29 will be good but the reason I would stay clear off aggressive rear brake pads is they trigger the ABS Ice mode (hard pedal in brake zones) which is something that is very annoying and was happening to me with Gloc R8 and up rear pads. This issue was so sever that with R18/R12 my stopping distances were longer than with DSUno/DS2500 combo and I'm very close in braking performance to G8x BMW's with RSL29 pads considering I'm manual and they are autos. So my advice is just stick with DSUno/DS2500 and don't over spend on pads.

The PP1 Front/Rears use Motorcraft part numbers but are in fact Ferodo DS2500 pads. You can just source rears from the Dealer closes to you which is what I do and the DSUno from a Ferodo dealer near you.

The 2024 Ford Mustang Dark Horse (with optional handling package) achieved the shortest 60–0 mph stopping distance in MotorTrend history at just 86 feet. This record-setting performance, utilizing Pirelli P Zero Trofeo RS tires and 15.4-inch Brembo brakes, produces 1.4Gs of deceleration, out-braking hypercars like the Porsche 911 GT2 RS.

So . . . does this ice mode thing affect my S650, too?

I wasn't sure what to do about brake pads when my OE pads wore out.

The S650 comes with a brand new brakes-by-wire system as well as a totally new Brakes Booster (by some reports with up to 150% more line pressure) and next generation ABS system and as you pointed out Bigger rotors and better tires. So I can't say for sure if it's there or not as no one reported Ice Mode yet on an S650. Overall the only reason someone wants different brake pads is for durability aka less brake pads used per lap or less cost per lap. However when you improve lap times naturally the brakes start to suffer more and more and the cost per lap will go up any time you lap times go down.
I like the DSUno so much because they seam to wear ok and deliver great lap times while also are very easy to source for me and price wise are closer to the OEM ones than to a real race pad. Also consider the fact that Gloc are an import for me.

So im like really late to this party, and I just scrolled through. There is a cooling product out there made by Redline called "water wetter" it basically alters the surface tension of water and allows it to absorb more heat, it actually works which is a side benefit.
I like Hawk DT70..I think is the par#, and it's pretty common now days to change pad composition to try and get the car to rotate differently, or less initial dive, etc. It's a real can of worms but we work on that stuff all the time. It seems like the more nannies on a vehicle, the more you have to modify things to get them to function as you want them, the car fights you all the way, you end up driving the technology instead of the car
( just like F1 these days) TeeLaw seems pretty close on spring rate, a lot of that is up to the driver, but I think that if you spend big money on shocks you will see some major improvement, anything under $5K is prolly not a good investment.
Welcome to the rabbit hole

My stock brake pads are Ferodo, and I am a slow beginner with a fast car (even if my instructor said I had a drive for speed that is very rare in students), so I will probably just replace them with the same Ferodo pads that Ford used for now, and maybe upgrade the pads when I get faster with more experience.

I was reading a lot about that months back. Some folks were reporting 10-15° F drop in temperatures over 50/50 coolant mixture, with one even reporting 20. Interesting stuff, if that is not all BS internet posting by folks who do not know how to control variables.

Not sure I would class a Porsche GT2 RS a hyper car

No it's legit, it helped keep my 13 to 1 MG Spridget alive in H prod.

Distilled water and either Redline Water Wetter or the VP additive. That's as good as you're going to get for heat rejection. The additive reduces surface tension for cooling and has a lubricant for the water pump.

The stock dark horse pads whatever they are seem to work pretty good and last a pretty good time on track. I bought Glocs to install when they finally go and interested to see what happens. 16 front 12 rear which was recommended by a sponsor and are pretty aggressive. Probably be happy with another set of stock pads actually as they don’t make noise or produce much dust and wear good. But pretty happy with GLoc on my “street” mustang and lots of guys use them that i know and will be interested to see how they compare (the 16/12)

What exactly are the “stock” DH pads? I ever to a dealer to see if they had any in stock snd he asked me for a vin. I said aren’t they all the same??? Interesting. Ferraro 2500 f/r?

What pad compounds do the competition Dark Horse cars run?

What pad compounds do the competition Dark Horse cars run?

The Dark Horse R cars run a thicker pad and a different caliper. Here you can hear the Brembo rep talk about how even the forging process is different.

Take a look at how thick those pads are:

They run an 18” wheel so not sure exactly what’s different has to be a smaller caliper and rotor but would be interested in pad compound

 

[Junkyard Dog]

For the low, low price of $7000 just for the front axle you can get lighter brakes and 25mm thick endurance pads on the front of your Dark Horse or Performance Pack GT

i think they have ceramic disc setup for 13k

The more i see about the R the better deal it seems

Takeaway here stock pads 15 mm i’m at 9mm so 1100 miles and 16 track sessions these only wore 6mm. Pretty good for a factory setup

I'd say so. Still more than 50%
