That kit is a waste. I have a friend who did the q45 conversion for under $100 including a caliper rebuilding kit. Same thing as a 'brand new' caliper but a little dirty...they can always be painted. :-p
BTW, it's the rears that lock up first on 240's w/ the z32 conversion, not the other way around. I guarantee the same thing will happen w/ the q calipers b/c it happened to me w/ the stock brakes! Either way, this can be remedied by a z32 brake master cylinder.

nope. the point of a larger rotor is that there is more material to absorb heat, and drilling/slotting only removes material, lessening their ability to absorb heat, as well as weakening the rotor. drilling the rotor is from back in the days when organic brake compounds were used, and they create gas which needed somwhere to go, hence the drilling. Now in the days of metallic and semimetallic brake pad compounds, no gas is created which makes drilling worthless. Slotting rotors does not weaken the rotor nearly as much as crossdrilled, and less material is removed, I dont mind slotted rotors as much. I know rally cars use them to keep the pads clean of dirt and snow and such, so i could see a use for this if you live in an environment like that. but you shouldnt be trying to race a 240 in the snow or mud or whatever anyway.
please noone say that porsche uses cross drilled rotors so it must be good; they use it because they have completly different materials in their braking systems and it is not nearly as detrimental. Porsche themselves has stated that the cross drilled rotors are only to provide a sporty look and increase initial wet braking.
but dont take my word for it, do your own research.

Yes, slotting is for deglazing. Also note that they are noisy and will cause oscillation in your car and brake pedal.
As for Porsche, they are actually cast in place so calling them slotted is a bit misleading. Either way, go to a track event and check out the Porsche brakes by the end of the day. Unless they are changing out their rotors, I guarantee you that almost every single one of them will have cracked rotors.

If your running street pads they'll most likely be at least part organic. Race pads that are all metallic or ceramic and stuff do produce gasses just at a higher temp that most likely won't be reached on the street unless you two-foot it. So yeah, if running street pads, slotted or drilled will help you if you are trying to "perform" something on the street. They don't cut stopping distance though. One quest. though about the whole Porche thing... I know the new ones have ceramic rotors. Yeah, then of course they would have to have holes cast in them cause you can't really drill ceramic very well, just try it on your bathroom tiles...just kidding don't. They'll crack. But I have never heard of Porches cracking rotors all over the place. I have only heard praise about the superior engineered brakes that allow some of the shortest braking distances. Correct me if I'm wrong, but I don't think Porche would mess up on something like this...

By the way, I have the 300zx brakes on the front w/ stock back and the proportioning front to rear is near perfect. I have never experienced the rear locking. I have the 300zx master cylinder and ss brake lines.

I'm not talking about the new PCCB system, I'm talking about everything prior. Cast iron rotors. Go to a track event and see for yourself. Stop assuming and start seeing. And I never said the brakes didn't work well.

"porsche sells a lot of cars to housewives who use them to go buy groceries and pick up the kids to school." chmercer
Your absolutely right. Sad, but true. Now, if I had a Porche... As Dori Dori sounds like he knows a lot about Porche brakes I'm not going to act like I do cause all my info comes from motor trend or some magazine and their brake tests... I'm just going to go on my experience w/ my 300zx brake upgrade and say that it is 100% better than my stock brakes. It's been about a year now since I did the swap and have had absolutely no trouble with them at all and they perform awsome. In a way it's like cheap insurance if that last 5 or 10 ft is the difference between a fender bender and being able to drive away clean as a whistle.
chickentendah1)Wait so will q45 calipers fit behind 89 non-sport package wheels? I have the "teardrop" ones.
2)And I was thinking of a 300zx brake swap btw, but I don't want to deal with a master cylinder swap.
1)Not sure about the Q45. The 300zx will not, though for sure.2)MC swap is not completely manditory but stiffens up the pedal. I just went all the way cause it was only $50 more.
As for 300zx vs. Q45, it is mostly a matter of cost as both systems will perform well. If you but the "Nismo" kit though you are throwing away the cost advantage factor. The 300zx might have a slight advantage with the thicker rotors for heat absorbing and disipating but probly not much. I am not for sure about the unsprung weight factor but I know I added about 3 lb. as the 300zx rotors are heavy but the aluminum calipers are lighter so it equaled that 3. That may not sound like much but you don't want unsprung weight handling wise.
