tommyboy Posted April 24, 2008 Share Posted April 24, 2008 I'm in serious need of some new rotors so I startin to look online. Well, I saw the cross-drilled & slotted rotors that Motorsport sells here: http://www.thezstore.com/page/TZS/CTGY/PBC06 Have any of you heard anything about these rotors? Any info you could gimme would be great. Quote Link to comment Share on other sites More sharing options...
nbesheer Posted April 24, 2008 Share Posted April 24, 2008 Those look really expensive and cross drilled is not very good. Slotted on the other hand is good. Look for rotors from "powerslot" their a lot cheaper and are slotted. I think Summit racing sells them Quote Link to comment Share on other sites More sharing options...

zx_drift Posted April 28, 2008 Share Posted April 28, 2008 go brembo. You won't be sorry. Quote Link to comment Share on other sites More sharing options...
hughdogz Posted April 30, 2008 Share Posted April 30, 2008 My Power Slots have lasted a LONG time. I'm not sure, but they might just buy Brembo rotors and slot them. I've heard that cross drilled aren't that great by comparison. They tend to crack more than slotted. Plus, with slotted, the gasses can escape while the slot is behind the bad. With cross-drilled the gasses can escape into the hole, but cannot escape out of the hole until after the hole leaves from behind the pad.

With vented rotors, the gasses can escape the hole behind the pad. However, our ZX's have non-vented rotors in the rears, so I still think slotted would be better in that case. Shoot, I thought it was a choice between bolt-on slotted or cross-drilled. If you really want a sweet setup and have ~$2000 USD to spare, go with the AZC six piston, billet calipers with the 13" rotors.

nbesheer Posted May 1, 2008 Share Posted May 1, 2008 Yeah I'm sure you have to pay top dollar for quality drilled rotors. But look at powerslot, they don't even sell drilled rotors, in fact they sell "drilled" dimpled rotors that have the "look" but not the problems I guess. http://www.powerslot.com/pages/pro_stop.html Quote Link to comment Share on other sites More sharing options...
(goldfish) Posted May 1, 2008 Share Posted May 1, 2008 Keep in mind both are very hard on your pads and not needed. Quote Link to comment Share on other sites More sharing options...
Chemicalblue Posted May 1, 2008 Share Posted May 1, 2008 Power slot said that they have discontinued the rotors for the s130s, That Sux. Everything that used to be available for s130s is starting to no longer be manufactured and at a alarming rate. Not to mention the super high prices for the few things left you can buy now, I'm betting that in five yrs I wont be able to drive my z unless I make the parts to fix it. I'm looking in to stop-tech now, Ill post the results. Quote Link to comment Share on other sites More sharing options...

hughdogz Posted May 1, 2008 Share Posted May 1, 2008 ^^^ I agree 100%. S130's are becoming popular again. You should have seen how many 280ZX's were at the MSA show this year. There was probably twice as many compared to previous years. I think it is because the S130's are over 25 years old, and have the less restrictive emissions requirements now (at least in California). Does this set up require and changes in the brake system,like proportioning valve, change in rear set up, or master cylinder? I'm not sure about the m/c, but I would think you'd need a brake proportioning valve. I think Dave? at AZC could tell us for sure. Even though the 13" rotors and billet calipers will definately give better braking (and bragging rights, lol) I'm not sure that the increased unsprung weight will be worth it. Also, I saw a set of the fronts go on ebay for ~$500 last week. The guy said that these won't work with the new suspension setup he's using. Does that mean you cannot run these with coilovers? Maybe he did a 5-lug conversion or something...hmm. Quote Link to comment Share on other sites More sharing options...

There was probably twice as many compared to previous years. I think it is because the S130's are over 25 years old, and have the less restrictive emissions requirements now (at least in California). I don't think it's because of emission standards. Here in CA right now there's no law that allows ANY change in required emission testing standards for ANY car 76' or newer. The S130 cars have to pass the same test they've had to deal with since they introduced the dyno test here in CA. As far as the rotors go. I wouldn't go slotted or cross drilled on a street car. In a street scenario, and even spirited driving the rotors dont' get hot enough for it to matter. It's more important that they've vented rotors (fronts are stock, rears aren't). You'd see a much greater impact on brake performance if you designed something to push air to the brakes imo. Vented brakes cool pretty well if you have good air flow. In my 81' I was able to easily lock up all 4 tires in the wet going 65mph on the stock brake system. The tires are much more limiting than the brakes in a street scenario.
