StopTech or Alpha Rotors and pads? Help me decide please.

@Dave@DDMWorks any info on your sway bar?

The sway bar is the same outside diameter as stock, which means that it can be installed in the stock sway bar mounts with the stock end links. What we did though is made the wall thicker, which increases the rate of the bar about 30%. On vehicles with stickier tires, the sway bar makes a nice improvement to the handling, since they will induce more roll in the Slingshot. This batch is all red, although they will be available in black in about a month also.

Did you use the backing plates maybe?

No backing plates. Had to take just a little off to get it to start over the rotor, then forced on. It was still tight/wear in for clearance. Screwed all the way in and used a little bit of force to be sure piston was all the way in.

I can not tell you able anyone else's product
Stop Tec is a leader in performance patented designed rotors.
This being said 95% of slingshot customer will be good just running our s
Stop Tec Standard size 3 rotor kit
For the track guy with big sticky tires and more Hp
Our big brake kit specially designed for the Slingshot using the factory master cylinder.

You can not warp them.

So is there much gain with the sway bar mods and stock tires?

I trust your opinion and experience Noel. So just upgrading the rotors should do the trick for most drivers?

I have the Stop Tech rotors from Noel with Hawk pads from DDM.
As far as stopping power I have never had an issue they are a great combo. If I could just get a more solid pedal with less travel I would be ecstatic.
I have beat them up on the street and on the track. I would consider a big brake kit but I love my stock size base wheels and the only option that will fit inside those rims are the Alpha set up. Beautiful as they are, cost is the only inhibiting factor. I think front only kits would be a nice option since 90% of the work is done up front and that would bring the cost down a bit.

Just my 2 cents

Just a couple quick notes -
Here is a good example of the force vs. temperature for Hawk Pads -

It is very important though that when picking brake pads that you work in the heat range that you are driving the vehicle. On the Slingshot, there is not a lot of mass to stop since the vehicle is relatively light and the rotors are actually rather large for the weight of the vehicle and its weight distribution. If you go with a pad that is overly aggressive you may never get the brakepad into its ideal operating range, which a lot of the times means lower coefficient of friction, more dust and non-linear braking force.

As for the big brake kits, the 4 piston or 6 piston setups if sized correctly will not apply more force to the pads, they do provide that force more evenly across the pad surface though to prevent tapering of the pad. All of the big brake kits I have seen use larger pads, our DDMWorks kit, Alpha's or Stoptech's all have larger pads than stock. The larger pad volume has the benefit of higher thermal mass. This higher thermal mass of the pad helps with temperature spikes under hard braking, takes more energy to raise the temperature of the pad and also the larger pad volume helps with longevity. The big brake kits also have larger rotors (14" on our DDMWorks kit, 13" on Alpha's, etc.) which also have more thermal mass also. Larger thermal mass of the rotors allows them to absorb the initial thermal load under heavy braking and since all of the aftermarket kits have better vanes internally, typically directional, they are able to disapate the heat faster than the stock rotors also. One note with the big brakes we found during testing of our kit, with the bigger pads and rotors it is actually difficult to get some of the more aggressive pads up to operating temperature at all, unless you are doing hard braking repetitively with sticky tires.

The other big factor to consider with braking is your tires. No matter how good your brakes are, the tires are what contact the ground and actually stop you. So if you have some really sticky tires, you can go with more aggresive pads because you can develop the higher friction with the road to stop faster. If you are on stock tires you really do not want to go with something too aggressive, otherwise you will just engage the ABS and never really get the pads to their operating range.

The slingshot setup stock is not that bad, mainly just a pad replacement takes care of most people. The 2 piece rotors are nice and offer better cooling and less rotational weight and with a pad upgrade definitely takes care of almost everyone. The big brake kits are typically not needed unless you are doing some hard track days with sticky tires, although they do look great

Hope that helps,
Dave

I have not changed over from my stock brakes yet and I really should with all the aggressive driving I do. I was looking at the HAWK HB-275-S.62 compound. Is this the best compound to get?

Hmm, if only someone made a front kit only...

That part number is for Hawk HT-10 pads, which are going to be a track only setup and take some work to get up to operating temperature (see graph above), probably not something you would want to run on the street.

The Hawk Brake pad part numbers work like this -

We will use the part number HB275S.620 as an example. The first 2 letters stand "HB" stand for Hawk Brakes. The next 3 numbers "275" correspond to the shape of the brake pad. The next letter "S" is the pad material/compound. The last 3 numbers after the "." are the thickness of the pads in inches. So a ".620" is .620" thick.

As for the pad material letters from Hawk, here is the breakdown -
F - HPS
B - HPS 5.0
Z - Ceramic
N - HP Plus
G - DTC60
V - DTC50
S - HT10
E - Blue
EE - Blue42
W - DTC30
M - Black

Hope that helps.

Ahh good to know. Some of the ones you have listed do not coincide with what is on the chart. So I am wondering what the difference in the Ceramic and the HP Plus is stopping wise and how is the brake dust comparison?

Ahh but do they fit stock base 17" rims?
That is the big question

Our BBK kit fits the OEM 17" wheel. It is expensive but it is also the only kit designed ground up only for the slingshot. With the stopping power it provides lap times are faster on the track as you are able to brake very late into corners and with repeated abuse they will not fade. @xd675x has been putting allot of track time on the brakes with great success. @Tango has them on his V8 monster as well and it stops that V8 in no time.

We also have our basic upgrade that includes drilled and slotted rotors, pads, fluid, and our master brace. If you will not be tracking your machine hard this upgrade would be well suited.
