Do you have An SE???

i do have an se, and yes, they are disc. but i am only conserned for the front rotors. the rear do very little work,

I thought that having disc all the way around they do the same amount of work..

For example when you hit the brakes hard or what not the car doesn't do a complete nose dive like it would if it wasn't 4-way disc...

Correct me if i'm wrong but this is my theory.....

they all do work but not equally. the master cylinder has a integrated proportioning valve that controls the f/r setup. i believe it is a ~ 60/40 split.

so wouldn't it be better to change all four rather than the two????

So you do'nt actually get say 70/30 percent performance rather than the original 60/40 split??

Am I making any sense??????

cause with the front's done you'll be getting better performance and less in the back so I was thinking do both so you are getting the equal amount.....

it wouldn't make a difference with my setup. i am only changing the rotors and adding braided lines. i am usng dealer pads, mainly beacuase stillen adn other high performance pads, it will wear out faster, but give better performance.

i like what i have, but only need to cool the rotors a little. mine are warped out, BAD!. plus, i am in l.a.,CA, and the drilled holes will help it cool up more.

p.s., it is more like 60/40 work load.

hey dood, r they factory redrilled rotors? if they are, i wouldn't suggest u getting them. if u do plan on getting performance rotors, its better if u got slotted instead of drilled. they'll crack on u if ur rotors were hot and hit a pot of water. i have my drilled rotors crack on my crx b4 and there werent factory drilled rotors either.

i checked with stillen. no, they are not factory. it tkes a month to get a finish product. they buy the rotors, and vents, acid wash(???), then drill(CAD CAM design), plated and cover it with something, then wooala...the finish producy..or so!

this is per the brake tech's from stillen.

· #13 · Apr 2, 2001

vented, acid washed? doesnt that mean stock? cause the stock rotors are vented acid washed. all rotors now days are vented and acid washed for cooling and reduce corrosion.

Greendot, cross drilling your rotors isn't going to help them cool any better. And if you work your brakes really hard (sounds like you do) there is a really good chance that you are going to end up with cracked rotors in the not to distant future. If you want cooler brakes, try and get more air to them. I'll also look into whether or not brembo's OE replacement rotors for the sentra have their pillar cooling design. That design is the most effective on the market right now.

i checked with brembo already, nothing but the big brake upgrade for the g20. well, i got the crossed drilled rotors (f/r) with the sport pads (f/r) and the brake lines, too, from stillen. cost a total of $650. i will instal it this weekend. i checked and asked around people who are in the business, and all said the corssed drilled will cool down quicker. most said i must change my braking habits.

well, stillen said the rotors are warranty against craks.

i will keep posting as i use on.

those freaken bastard in stillen sold me the wrong crap again. they told me that the new part numbers are for the b15 2000 sentra. WRONG!!!! still too small to fit. wrong rotors, wrong pads..but the lines fit.

the corss drilled rotors looked good, but i returned every thing back for a full refund. this is the second time...you folks be carefull what you get from stillen, those sales rep do not no ****!!

I'm just trying to clear up this whole brake cooling thing. Greendot, I wouldn't trust anything Stillen says. They'll say the rotors add hp if they thought it would increase the chance of a sale. You asked the salesman if they would cool better and of course, he said they did.
Cross-drilled and/or slotted rotors do not increase heat dissipation. Their sole purpose is to reduce brake fade by wiping the surface clean and allowing gases to escape. The vents they put on rotors are there to dissipate heat. Cross-drilled rotors actually decrease heat dissipation. You are removing the material from the rotor, the same material which acts like a heat-sink and absorbs the heat from the brakes. If you are replacing your rotors because you are having heat problems, cross-drilled wouldn't be the way. You would crack and wear those out way before the stock rotors. I personally feel slotted to be a much wiser choice for street cars. If you need to cool down your brakes, you should try something else. Changing rotors won't do anything for cooling.

okay. fine. i learned my lesson from stillen. i even complained to steve millen, that bloody brit. he didn't care, all he said return the products and talk to someone else.

well, for x-drilled rotors, there might be a chance for cracking, under EXTREME heat and driving conditions. i don't race!

for cooling, i have spoken to (mainly porsche people, cause my brother-in-law is a porsche freak!) and said x-drilled is more for agressive driving, and slotted is for street driving. both will disipate a certain amount of excess hear. metalic, ceremic coated, and carbon-metalic pads act better under higher temps then our semi-metlc stock pads. the holes/slots are to clean the pad, plus release the trapped gases between the pad and the rotor.

well, there is something to it, but we will never find out in our sentra's...soon!

note:

according to nissan dealers, the new sentra se's use the altimas braking system (pads/rotors). the idots in stillen weren't aware of this, from what i gathered from the brake-pros tech dept (stillen). their inverntory lists the rotors/pas as 89-2000 models, with the older se-r rotors(10" with 4x100). the new sentra se' use 11.5" rotors with 4x114. stillen is making those rotors for the 2001> altimas within the next 2-3 months. i wouldn
t hold my breath.

however, the good news is that the g20 oversized brake system will work on the sentra se. also, a newer version is to be released in 2002 for the new upcoming se-r vspec sentra's.

this info is per Dan in stillen brake dept.
