Re: Anybody here with Evolve Rotors (S60Rguy)

I have the "E" slot rotors. I like them. My stock brakes had gone to crap, so I can't really give you an honest "stock vs. upgraded" comparison because I was comparing old stock to new upgraded brakes.<p>overall, they stop great. nice bite, good stopping power. I love the little "whirring" sound they make as I come to a stop. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0"> subtle...but you can hear it. (i cant' hear it with windows up..only if they are down - it's not *that* loud...)<p>i also added the SS brake lines - which probably helped as well.<p>they are definitely lighter than stock. i mean, they are still heavy - any rotor is heavy..they're iron rotors with aluminum centers...so it's not like they are featherlight....but they are noticeably lighter than stock rotors that are solid iron. anytime you reduce unsprung weight, it helps the car. i can't say how much though. <p>they definitely look cool. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0">

Re: Anybody here with Evolve Rotors (S60Rguy)

Here's a good thread to read: <A HREF="http://forums.swedespeed.com/zerothread?id=47132" TARGET="_blank">http://forums.swedespeed.com/zerothread?id=47132</A><p>Do a search for Evolve Rotors in archives.<p>I really like mine, they helped me out yesterday when an idiot decided to cross all lanes to make a left in front of my accelerating car. I am sure the stock rotors would have worked just as well.<p>I also have their brake pads and don't have any problems with premature wear and tear. They also work well in the rain, they weigh about 5 lbs lighter than stock.<p>The downside is that they are rather expensive but you only have to change the rotor and not the hat when you replace them. Plus, they can not be turned if you have warping. You also have to adjust the e brake from around the shifter after installing the rear rotors. The hub has a larger diameter to it and requires the e brake to be pushed out. The hub also doesn't have an e brake pad, so since it is aluminum, they might be wearing out quicker. The next time I check my rotors, I will know if that is true.<p>BTW, I have the E slots....had them for over 11K miles so far. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

Re: Anybody here with Evolve Rotors (Kirb)

Wow!!! those calipers are sweet...<p>Cool thanks guys...I am doing a track event in April and i want some better braking performance...the stock brakes right now feel extremely squooshy...if anybody knows what i'm talking about...<p>I want to get that nice firm pedal feel to the brakes...can that just be better acheived through upgraded pads??? i already have the SS brake lines but it really didn't do much with firming up the feel...<br>

I can attest to Kirb car's braking powah! Those 6 pistons stop the car on a dime!

Re: Anybody here with Evolve Rotors (S60Rguy)

Got Evolve rotors on all 4 corners on my V70R.<p>About 100-150 miles after the install, started to get vibration/pulses when doing medium braking. Took the front rotors off and sand the surface with emery cloth after reinstall pulses gone. However these pulses/vibration kept coming back and after 1000-1500 miles become unbearable. Repeat with polishing the rotor surface with coarse emery cloth and vibration/pulse dissapear. Repeating this procedure every 1000 miles get tiresome though. Even develops the habit of braking lightly coming to a stop to avoid this vibration/pulses.<p>Called Evolve several times to resolve the issue. Got a call back from the rotor manufacturer but he only promised to help but that's it (just promise). Evolve does not seem to care anymore.<p>I put back my stock front rotors in the meantine and no vibrations/pulses when braking at all. It looks like there is a slight run-out (thickness variation) on the front rotor surface that causes the pad material to deposit more on the high spot/s hence the vibration with mileage.<p>When I got time I will take the rotors to a brake shop to have them resurface the rotor slightly to get them even.<p>I can say though that Evolve aftermarket support (talked to Don, Keith, Matt) is just not up to par <p> <IMG NAME="icon" SRC="http://********************/smile/emthdown.gif" BORDER="0"> <p><br><i>Modified by awdnut at 6:49 PM 3-17-2006</i><BR><BR>

Re: Anybody here with Evolve Rotors (awdnut)

I second the support from Evolve. Don is less than impresive. I only had a 3000.00 order with him a couple of weeks ago, had a few issues.......he treated me like I had a 50.00 order with him. Belittleing and rude. That will catch up to him and his company. <IMG NAME="icon" SRC="http://********************/smile/emthdown.gif" BORDER="0">

Re: Anybody here with Evolve Rotors (awdnut)

Odd, I don't have that pulsating feeling unless it is under heavy braking, and that is attributed to the ABS kicking in. Under light to medium braking, I don't have any issues.

Re: Anybody here with Evolve Rotors (Kirb)

Like I said. This is most probably because the Evolve front rotor on my car have more run-out than it should. Yours is probably OK (no run out problem). It could be one manufacturing tolerances or just my bad luck.<p>What I am saying is that in my case when something is possibly wrong with their product, Evolve simply walks away from it.<p>

I'm going to the Ring in Apr though. <p>It does make more sense that the discs get high spots from deposits though.

Re: Anybody here with Evolve Rotors (wrxownr)

Denny:<p>On my car the vibration is not like when you have warped rotors (where it vibrates on light to medium braking and gone on hard braking). The vibration is hardly perceptible on light braking yet on medium to hard braking it is as if the car decelerate more everytime the pads hit this high spots on the rotor. On freeway exit ramp when you medium/hard brake to slow down, the whole car vibrates. . . . .very annoying!<p>When you lap the front rotors with rough emery cloth until the rotor surface does not look shiny anymore, the vibration is gone/reduced and I have gone thru this procedure 3-4 times.<p>In the one time the brake manufacturer called me back, he was suggesting that the depositing problem is caused by using the soft stock pads but apparently you are getting the same problem using harder pads (HPS).<p>I just think that it is ironic that Evolve is marketing their brake stuff with all the hoopla about slotting vs. cross drilling and yet severe brake vibration/pulsing problems fall into deaf ears<p> <IMG NAME="icon" SRC="http://www.vwvortex.com/zeroforum_graphics/screwy.gif" BORDER="0"> <p>

I had four Evolve rotors but have since removed the 2 rear ones due to this pulsating vibration. Now running stock rear rotora and problem almost gone except for some squeaky noise that is probably shocks related.<p>Don any help, it appears it may be Evolve rotor related.<p>Randall

Re: (Randall)

Sorry for the late post...I have the same issue with my rotors (though I didn't know what to think about it). I notice it when I brake from a higher speed. I tried taking my foot off the brake and re-applying the brake and the vibration stays there until it slows down.<p>Maybe heat adds to the problem. I found a nice road that I was able to take my car up to 140 and when I slowed the car down, I had the same problem. When I got home, I noticed that I had 3/4 inch heat circles around most of the rotors about 2/3 of the way out from the centers. The heat circles have left over time and I really like the rotors but it is also bugging me.<p>I also had to tighten up the e-brake because they were no longer grabbing...my car would roll a few inches and if the car was pointed even slightly downhill the car would just continue to roll (even with the e-brake all the way up).<p>Anyone notice the vib on the regular slot or just the E slot like me?

Re: Anybody here with Evolve Rotors (UPDATE)

Well:<p>Monday last week (2/20) morning, I got a call from Martin (GiroDisc) who is the manufacturer of the Evolve rotors. Apparently he was involved in an offroad motorcycle mishap which requires hospitalization and he is currently on crutches and unable to drive a car (his father is driving him around for him to do business). Anyway he offered to pick up my Evolve front rotors and machine them on his own lathe machine.<p>Tuesday afternoon he brought the rotors back to me. We suspect rotor thickness (not warpage) is the source of this recurring vibration. <p>After 250 miles driving with them I can say that the vibration is gone. Times and more mileage will tell but before the machining I usually get this vibration back within 100 miles (after roughing the surface with emerycloth). Hopefully this will end the problem.<p>I am also working with Martin to try to resolve the rear parking brake problem with the Evolve rear rotors. I have the early Evolve rotors in which the inside diameter of the drum/hat is bigger than the stock diameter. <p>HTH,<br>

(I might have the early rotors as well.) Keith sent me an email asking to talk to me about my problems. What amount did you take off your rotors and what is the thickness now?
