why cross drilled rotors?

Hank Scorpio · 11-08-2002, 01:22 PM

MAN THOSE LOOK SHARP!

Get some detailed info up about them could you? I'm sure lots of the R people here would love to know about it!

here's a nice thread about 13" brembos, dave's got some nice porsche brakes....and there's also the ap racing kit i found (available at eurosport tuning ).

i luv these, they're great...not so much low speed (that i feel stiffer is prob because of the stainless steel lines) but high speed is amazing. i do have this annoying problem with shudder at 40 mph when brakes r applied...stillen (where i got it for 2299 + 3 bottles of motul 600) said it's normal...phh...they even machined my new hubs (which they told me to get) to get rid of the lip on the edge. that kinda took away most of it, but it's still there. other than that it's great. pads r a cinch to change, much easier than the stock single piston sliding caliper front. just have to becareful when the mclaren clips need replacement. afterall, the rotor and hat assembly is semi-float. found another guy here in sf with the same kit, he never had the shudder problem, but he had to replace rotor and hat because he ran too long without the clips...

i don't get much looks, prob cause i'm in a volvo :D and the caliper is black. as for cross-drilled? i guess it's to provide a better initial bite. i would've prefered the brembo f50 kit, with slotted and cross-drilled pattern...but it doesn't fit on our car...so, i'm left with a fairly busy looking lotus kit. at first, i thought the rotors were backwards, because it looks as though it's sweeping forward at a pretty perpendicular angle, but it's actually correct; just look inside at the ventilation...

obtw, here's the link to stillen's kit number 305850 brembo pdf file and stillen brembo webpage (pic is wrong, it's showing f50 kit)

Sweet Steve, looks great.

Do you think you could have a bad wheel bearing? My first guess would have been warped rotor, but sounds like that was rechecked.

Hey, are you doing the Dec. run w/ the golden gate chapter? If you are I'll probably see you there (should be driving the 242).

Steve,

Those are the brakes that got me started on this kick, but I didn't want to pay the $ 2600 which is the advertised price, AP Racing and Mov-it are two other companies that want about the same for their kits. They sure do the trick don't they? Did you find that the stockers were terrible? I have had nothing but problems with them.

I am attempting to make a budget kit with the four piston porsche/brembo calipers and the VW Passat W8/12 rotors which are 13.25" (330mm)and they are 1.25" wide, and directionally vented. Right now I have about $1200 in the setup and all I have to do is mount them. I expect it will take about 4-6 hours to make the bracket. I am going to post the process once I get going. I am replacing the shocks with Bilstiens and make a strut tower bar too. I am going to document the entire project and post it. Under the heading...how to make a brick fly or something like that. I will also be putting the engine mods too.

steve s · 11-09-2002, 02:30 PM

something like dave's kit? that'd be nice too :D . i just need some more braking power when i haul a bunch of stuff, when the wagon's loaded...plus, a safer feel at high speeds.

steve s · 11-09-2002, 02:32 PM

no, all hubs and bearings were good, and all the runout data were within both volvo's specs and stillen's specs...gremlins :mad:

By the way the cross drilling is for cooling. When you drill a rotor you increase the surface area of the rotor therefore increasing the cooling area which then gives you better braking.

As for the slotted rotors. These are called flame slots. The reason for these is that when brakes get hot there is a thin layer of gas between the pad and the rotor. This gives you a spongy feeling brake pedal. The flame slots allow the gas to escape and get better contact between the rotor and the pad surface, thus better braking.

The ideal situation is to have both. If you had to choose between one or the other I think the flame slots would be my first choice over cross drilled, but with a 13" rotor I doubt you really need either...

By the way where are you in SF? I live in the Sunset.

Dave who?

Shudder? Like wheel shake? That is the problem I have with the stock brakes. My problem is warped and heat checked rotors.

steve s · 11-09-2002, 06:39 PM

dave, moderator on volvospeed.com. near j-town. the shudder only happens at 40 mph...not on lower, not on higher speeds...i had stillen look at it...seems as tho they're within spec...

Evan · 11-17-2002, 10:53 PM

Dang, those are nice. I was gunna grab some of those, but I have spent too much money lately, and then last night my driver side window got broken (like, completely..it came out in one peice becaues of the tint, but..yeah). I wanted to cry, but I was too f*****g pissed off, I wanted to kill someone. Anywho, I don't have to pay for it, it's a long story..so I guess before I get better brakes I'll have to throw some more limo tint on the driver side (it/she/he/they/etc is not going to pay for the tint).

sorry...must've missed ur post...u need to do this :apoke: to me :D

i guess the cross-drilled is there for better initial bite on the rotor by the pads. the cross-drilled design are for better out-gassing of heat generated when the pads and rotor rub...slotted designed (which i don't have) seem to help "swipe" the hot gas out, and helps maintain a lower temp on the rotors. don't ask me why it's so, i've been reading everywhere and that's what the two do...no one really provides with me any data. anyway, the cross-drilled rotors are the only ones that came with the lotus brembo kit. the slotted and cross-drilled f50 kit apparently is too big for our cars (heavier also, although i'm sure it can be done).
