Ok guys I will proabably need to rebuild my calipers since my car pulls to the right and I hear a slight poping noise from them when I brake I want some good rotors and better than stock so I was thinking about getting X-Drilled or slotted and have been looking for some since 10 AM (seriously i have looked for months but can't decide) ok I have seen the ones from these places and checked pricing on them:

Victoria British Catalog: X-Drilled rotors (Front set) 5-lug $229.95 for the set

RX7STORE: BREMBO X-Drilled rotors 120 USD each
$240 for the Front set of two

Corksport: KVR Cross-Drilled Rotors -Front ('86-'92 5 bolt) Price: $148.00 each 296 USD (PAIR)

Mazdatix: Front 5-bolt X-Drilled $159.75 Each 319.50 USD (Pair)


Ok this is what I am up to now. I would like to get the BREMBO ones from the STORE since they are a good name and are the cheapest so far. The prices above do not include shipping. Can anyone give me comments on any of these rotors?

I got the Powerslots from the RX7Store a while back. I'm using the Hawk HPS pads with them and they work great, no noise, normal dust.
If I remember correctly, Powerslots start out as a Brembo disc.
Concensus is that cross-drilled will form cracks at the holes (I have no experience in this, just what I've read over the years on various forums)

 

Slotted for a street car are just fine.

But they can crack under hard use. These are off my Trans Am after a 2 day session at Thunderhill. Brand new when I started.

damn! that looks harsh I don't really autoX but I might start later on when my car is up to it.

 

bump anyone else with oppinions

$240 for all 4 zinc-plated.

 

I'd go with slotted over cross drilled. Get better bite with slotted on the street. Cross drilled is more for high speed track use and on the street mainly looks.

 

Slotted eat pads a lot faster than drilled do, but drilled ones crack a lot easier. It's your car, pick whichever you want.

 

Im using a cross drilled KVR setup from Corksport. They've seen many hard driving days and so far they've held up great with no cracks.

If I had to do it again, id go with slotted/cd'd front and just cross drilled rear.

 

go to www.pureperf.com front rotors are no more than $80 each for the front and you can have them cadium plated so they won't rust. i have them on my car with their pads and i love them. i also believe they are brembo.

I have used both cross-drilled and slotted and a combo of the two. All have ended up cracking. Slotted and/or cross-drilled rotors show no improvement in braking whatsoever. Some claim as I do that cross-drilled actually take longer to stop possibly due to less sufrace area the pad is in contact with. Others claim slotted initially bite much better (in their head I think), and clean the pad but I have never been able to tell the difference. Unless you like the look of the cross-drilled etc. (like me for my vert), I would go with plain rotors if you really want performance with longevity of your pads and rotors like most race cars. The best performance gain with the stock braking system can be achieved with a proper selection of pads.

 

From what I understand slotted are meant to let brake gases escape off the rotor so that the pad may make better contact.

I have heard that cross-drilled eat pad. Think cheese grater, supposed to have the same effect.

I've also heard that for "normal" driving plain rotors are fine. That the advantage the other types provide isn't needed and ends up being mainly for show.

In the end go with whatever you think is best. Your opinion is the only one that matters for your car.

well the thing is I don't drive "normal" like today a stang was trying to get it on then a neon up ahead pulled into my lane and I had to to the 75 to 35 MPH test and I also brake harder than normal when my whistler goes off.
