Has anyone used KVR brakes before? i know they make some decent suff, but i have heard nothing about how the rotors hold up. i am thinking about getting the cross-drilled ones with black cadium plating.(corrosion resistance, and looks MINT!)
all i'll say is that i'm strongly against cross drilled rotors. rotor chunks are not cool. Slotted will do just as good if not better untill you get to extreme race level stuff.
there was a debae on here awhile ago which was stroger cross drilled or slotted, and while they determined that they will both break under heavy conditions. supposedly crss drilled rotors will last longer, and cool faster (preven future warpage) anyway i normally dont go to tracks or race, so either or would be sufficed to improve my stopping
Because i don't really wanna spend all week in an E-Debate, i'm just going to say that i disagree with you, and let's just leave it at that.
Martin, call Mark Link at deversified (in the vendor links). He should be able to swing you a pretty good deal on some rotors that are cryo'd. Russ
While I think Shane has a point, I don't think it is an issue on street driven machines... Yes, they are more likely to have problems, but how many times do you hear about it in motorsports, let alone street driving? I would be more concerned with the brand, than whether it was x-drilled or not. As for KVR...they embraced the Suby community many years ago, as a matter of fact, I put KVR pads on my RS as its first pad upgrade, in 2000 I believe. Back then, they were known for their quality, but I have not heard specifics on the rotors in more than 4yrs. I suggest searching NASIOC from 2+ yrs ago, if you can... EDIT: I agree with Russ, too, I am currently running PowerSlot rotors that were cryo-treated at Diversified.
http://www.frozenrotors.com/ravingfans.shtml (Notice the plug from Champion Audi!) ...and from what I can tell, they don't rust. (My car is in the garage unless it is at an AutoX or Track Day)
i did the search, and my car isnt offered :-( perhaps i was misreading the info i found on slott vs drilled: what are the pros/cons of each?
I see a listing for '97-'01, not sure what is different.... Either way, they are selling their own rotors, but I believe they would cryo treat any rotor you buy. I bet that if you give them a call, they could help you out. However, there are obviously other choices, too. BTW, I noticed that the look of the plated rotors was part of your desire...I believe the plating wears off the rotor where the pad contacts so they wouldn't look so "clean" after a while. ....just something to think about.... As far as slotted vs x-drilled....for your indicated intended use: no difference
the 97-01 is the rs, so those rotors probably need 16" wheels to be cleared. i am not sure about the cadium plating, and how long it lasts, i will hae to find out. as for slotted/drilled. is there enough difffrence in longevity of pads/rotors , brake fade, gas dispersion, cooling and all the other goodies that makes it worth getting slotted/drilled rotors for SPIRITED daily driving
Call Mark, he can hook you up. He can get stock rotors and have them slotted and cryo'd for ya, or he may have other options for ya. Just call and see what he can do. Russ
http://www.frozenrotors.com/frozenrotors.shtml it's a bit more on the summary side of the site. The main reason you don't hear about it in motorsports is because: A) it's a well known and accepted problem b) the rotors they use are actually cast rotors. they were made with the holes in them to begin with. this in turn makes them stronger and more resistant to the cracking. c) They use consideribly diffrent pads than the weekend racer. most weekend racers just use the drilled rotors with a street or agressive street pad. they tend to wear on the rotors harder than a race pad actually does. most teams find that when they remove the rotor at the end of it's lifespan, that it is infact THICKER than when they put it on (i'll be it a very small amount). There was a very interesting write up in Grassroots a few months back about brakes, rotors, pads, etc. ah crap. and i didn't want to spend my whole afternoon typing. =(
i read up alittle on the cryo freezing. it seems like it puts the molecules of the metal into a stronger alignment so it is harder, and denser. isnt this essentailyl what forging does? why dont we see forged brake rotors?
You are referring to high-end competition, I was referring to club racing, autox, HDPE, etc. At this level, they don't necessarily use different pads (although I do use a track compund), there are some manufacturers that cast the rotors with the holes (most BBK do not use these due to expense) and it is not an accepted problem. If it was accepted, they wouldn't be used (circular argument).... Bottom line...I know people that rally at a pro level that use slotted and/or x-drilled rotors, I know people that club race that do the same, etc.... It is not the serious issue you paint it to be. Do I use them? Yes I run slotted rotors on the RS for AutoX and Track Days....never had a problem. Again, if you find a reputable maunfacturer, I wouldn't be concerned on a street driven car. Any way, it is now my $49.95....and I thought you didn't want to get into a debate, Shane!
i didn't/don't. i'm not saying another word. pick whatever you want, personnaly, i'll always opt for slotted rotors, because i have seen video of a rotor exploding through a wheel on a track. it was a drilled. Granted, it was probably over used and poorly maintained, but that image in my mind is more than enough to stick to slotted.
Slotted rotors Hop on ebay. Look up this number... 7999091672. This is for a set of 4 slotted rotors Shipped for $165. I bought these rotors earlier this summer. I needed new front rotors, but got all four for less than the cost of two at Checkers. I have the fronts on with ceramic pads. They work great! The seller is "easyautomotive" and has 100% positive feedback.
