Rotors- slotted or cross drilled??

[slickkedar]

Which is better and why?? Also, im thinking of getting some aftermarket ones- which company is the best??

[G22DET]

Brembo is the best, slotted and cross drilled all serve the same purpose..allow heat to escape from the brakes faster.

I'd personally go for slotted rather than cross-drilled, as cross-drilled rotors have been known to crack.... and that isn't cool

[G22DET]

not if you get the brembos...i have them for about a year now...went to various tracks and they work great.

Cross drilled rotors are sweet as, but if you cross drill existing
disc rotors then they crack.

Brembos kick ass! The Godzilla Skylines use them and they stop
faster than many of the supercars today.

Get them for looks if you like. If you are getting them because you are hoping for better performance, you won't get any. So, if you want to get them for performance, spend the money elsewhere. A better set of pads, or better yet, SS lines would be a better investment.

i totally agree with George. :smoker2: For street use, better to go with non slotted/cross drilled. for the track, it MAY help with brake fade a tad more, but good pads will do that as well. I mostly see people doing this for form over function. Brakes are the area where function over form should be the general rule.

as for pads, EBC Greens for street, Reds for track. Hawk and AXXIS (metal masters) also make damn fine pads. As for SS lines, I got my set from STeve @ SMC over a year ago and have been completely satisfied! A great investment for any kit! (pretty and match my blue calipers... Also, a good brake system flush and some good brake fluid wouldn't hurt either! alot of guys rave about motul, but i have only used castrol dot 5 abs myself. (since i have ABS)

On a side note, SMC has a BABK for the P10 using redrilled hats from a 300zx Turbo. You will have to supply the calipers though. May want to check that out too!

This is true if you drill solid rotors. Brembo casts there rotors with slots, so thats why they dont crack (i think)

I needed to replace my rotors not to long ago. Rather than go with solids from the local parts store. I flipped an extra $40 and got the Brembo Cross Drilled/Slotted rotors. They look great, but as for better stopping power, I dont think I notice any difference. I guess you would need to upgrade to a bigger brake kit to get better stopping power.

Would cross drilled rotors help in stopping any warping of the disc? ...lets say if we were braking on the street rather hard...

Check out these upgrades for the G20/ SE-R

11 1/2 inch cross drilled and slotted rotors...
SS brake lines
If you get the stage 2 kit it comes with new calipers

I think its like 2k or somethin tho...quite alot

Slotted is the safe way to go. Drilling and slotting does not acheive the same end. Drilling is to help the disc cool faster. Slotting is there because the act of braking makes the pad release a gas that impeads braking, the slots release this gas. As for getting more braking power. Larger rotors are not necessarily needed. A high quality rotor and super grippy pads (Metal masters) will yield a great increase in braking preformance. But you only have so much grip, so get some wider wheels and tires, voila you have just shortend your braking distance. Not that the G20 had a long braking distance to begin with. P10 G20 with ABS did 60-0 in 125 feet, thats super short folks, Mustang Cobra territory (BTW the Cobra is regarded for having excellent brakes).
