im looking into some brimbo rotors for my integra, i wanted to know what yall think, which is better drilled or sloted?

 

IMO, drilled is better. But both is even better to have.

 

get slotted! Ive heard of alot of people with drilled rotors craking

 

get which ever you like. neither will provide any benefits in braking on a street driven car. both will promote faster pad wear, with slotted being the quicker of the 2. neither should have any problems if all you do is daily driving (e.g. they won't crack). if you plan on abusing them at the track, the drilled rotors may crack as drilling the holes (instead of casting them during time of manufacture) creates multiple stress points. Unless you're putting them thru the abuse of racing tho, you won't see any downsides aside from pad wear, but you won't see any additional benefits either from the drilling or slotting. Plain rotors actually provide more contact area between pad and rotor surface, keep that in mind. HTH.

 

Skip the drilled/slotted crap and just get some blanks. Anything else and you're just asking for the stupid things to crack.

 

Neither. If you want overall solid perfomance.

If you want to look cool, buy some lighted windshield wiper nozzles instead.

I agree, don't get either unless you plan on doing some rally racing in mud. hahah i hope not tho.

 

Cross drilled is old technology and will only help you crack the rorors.

The reason for them being cross drilled in the past was to allow gasses from the pads to escape, pads do not gas anymore..

Slotted? The slots will just fill up with dust and then they are not slotted anymore. Just get blanks...

The more mass the more better heat dissipation, less fade, the better you stop.

 

does anyone know of a big brake kit that are solid rotors?

for overall street/strip performance..go with brembo blanks...i guess thats what thye call them...very cheap too..i like $ 130 for all 4 corners

if u do a search under brembo...many people have info as to where to get the rotors from

I couldnt agree more. I made the mistake of starting my mods with a all-four-corners brake upgrade to powerslot rotors, and what a waste of loot that was. the slots filled with brake pad dust and other road crap, rusted fast in the slots. ugly. Plus there were no perceptable improvements with the new powerslot rotors.
So since then I have changed my thinking and have nice beefy front and rear ITR sized brembo blanks from fastbrakes on my cars, an EG and a DB8 (which has 2 piece front rotors, but still NO slots or holes)
Now, the pads I ran made the most changes in brake feel, so try to find a pad that fits your driving style the most, and just get plain-jane Brembo blanks.

The AEM cai w/bypass does not cause a Hp loss as great as 4whp... but it does lose a pony or two.

Damn, if you rev any GSR or B16 head past 8K you're gonna need upgraded springs/retainers, regardless of LS/Vtec or not... just to clarify.

Actually, brake pads do build up gasses under the extreme heat of braking conditions.

Cross drilled rotors will give you superior performance under high speed braking (read that highway braking), they will allow the dispersion of built up gasses from braking as well as allow the rotor to maintain a lower overall heat during braking. The downside to cross drilled is that they are prone to spider cracks and have the least surface area of similarly sized rotors, which is the reason for their poor performance on the street... less surface area= less braking ability and more time to heat the pads to premium operating temp.

Slotted Rotors provide basically the same benefit as cross drilled, but are less prone to cracking. The downsides are that slotted rotors wear the pads much faster than any other type of rotor and slotted are also more difficult to resurface and require a special machine to do it, many shops don't have it on hand.

Regualar blanks are the best for street driving. They heat the pad quickest, are not prone to cracking, don't promote accelerated pad wear, are easy to resurface and cheaper. The downsides are that since they build heat faster, they are more prone to brake fade and they just don't look as cool as a rotor with piercings !

 

hehehehe rotrs with piercings

i agree with everyone else. do with blank rotors. i just got my OEM size brembos. i love them, i doubt theyre any worse than slotted or cross drilled maybe even better

 

well maybe they outgassed a few decades ago.
pad materials are different nowadays and do not release as much gas as was common in the past, so this argument supporting holes or slots is wrong...

 

Yes it is. thanks.

 

Get OEM Brembo Blanks, they are cheaper and perform just as well or better.

 

i just went w/ Brembo Blanks (solids) and hawk HPS pads.. i like my set up alot.. their pretty cheap too for OEM Brembo Blanks.. i got mine for $28/ea (plus shipping $10/ea) at http://www.collettimotorsports.com

the X-drilled will have little cracks and the slotted will wear your pads down quicker.. if you must go for one of these.. get the slotted.. but for me.. i just went w/ blanks.. Brembo quality, they were inexpensive, and effective

 

ha! i got a better deal, i got about 12 bucks on you
try http://www.performancemotorcars.com
theyre 31.64 a oeice but the shipping is free if you order over 50 bucks
HTH

 

I've got the Brembo rotors with both.

 

I've seen a groupbuy going on at groupbuycenter.com for some brake rotors and/or possibly pads.

Read their description, they explain why their product is "better" than other brake kits....

 

These cars do NOT have cross drilled rotors. They have the holes cast into the rotor when the rotor is being made. This gets around the weaknesses caused by drilling. The assumption might be that these cars have this type of rotor because it gives them superior braking, but that would be false. These high end cars use this type of rotor to save unsprung weight from their usually massive brakes.

Just to go on record with some of the others, just get Brembo blanks. Anything else is just looking for trouble and is a waste of money.

 

Bocian: WoW thats a great deal!!!! thanks

 

your answer is in the post you quoted.. when the holes are cast into the rotor when its being made/manufactured.. its stronger than when they (the company) buys a blank (solid) rotor and drills it after the fact (after its made)... and then reselling the blank (w/ holes they drilled) as cross drilled

 

Sorry to burst your bubble, but this is totally untrue...

The event of outgassing still does occur with today's brake pads, although to a lesser degree than years ago, when asbestos was a primary matierial in pads.. but gassing still does occur. Your prior statements would be akin to saying new pads are dustless, when they only produce less dust than previously.
Only full metallics would not suffer from outgassing.

*Gassing only occurs during HIGH speed braking, not street driving/ or a street course race.

*The same dirt/dust that builds up in slotted rotors is what would normally accumulate on the rotor surface (it's better that it accumulates in the slot)

*Cars like Porsches and the Benz E46 that come with the 'cross drilled' style rotors will only save about 1-2 lbs from hole casting (the loss of rotational mass and reduction in unsprung weight is not as detrimental to performance as in a 170-200 Hp fwd, plus these cars are considerably larger)...

The primary purpose of putting such rotors on these cars is that they are used by people who drive on roads/at speeds such as the Autobahn (or Montana for that matter.. ) where braking conditions are more than likely to occur at over 120mph... and as wonderful as solid rotors are... they will typically fade under these conditions, as Xdrilled or slotted (or both) will typically not. Aside from the fact that I have verified this prolly doesn't mean much in the H-T land of "I'm right because I think I am...", but that is why things are the way they are.

BTW
The reason porsche owners in the US switch to solid rotors would be that they are living in the US and do not break 100mph daily for extended periods of time, therefore solids would be more desirable for typical street driving.
