i have cross drilled all my rotors on both my sol and my talon and have had them for almost a year, and i have no problems whats so ever.is it worth it?Not really a big change, id save the time and cost and buy a big brake kit.

wow, we got some pretty good discusion going on in here, I thought it was just going to by my lame *** posts followed by a few "ur dum" comments.

I want to do autocross so I'm more inclined to get the slotted rotors, but I can't quite decide. good thing is I don't have money for brakes right now.

I'd be more inclinded to slot my own with the right equipment. I know someone that did it and it worked fine. I've been running powerslots up front for about 3 years now and so far I've gone through about 3 sets of pads, but the rotors are still in good shape.

I really didn't expect this kinda turn out, but hey a lot of good points.

I'm not going for the rice look on this car, it's a ------- volvo.. an older one at that, it would be impossible to rice it out.

I'm not trying to go for more power stopping either, granted this car is pretty damn heavy the brakes on it will throw you thru the windshield, they are extremely touchy and very very strong - I'm very pleased with the way they work stock. A big brake upgrade is virtually impossible for me to do, the car comes stock with 4 piston front/2 piston rear calipers. Bigger rotors are pretty much out of the question too, the lug pattern on that car is so specific, it only shares it with the other 200/700/900 series volvos and all of them pretty much have the same brake setup. Yes the 850/V series have a similar lug pattern but that would take some fabrication to get one of their rotors to fit since the offset is way off.

So no, I'm not going to go out and buy a brembo brakes for one of my volvos that have over 200k miles on them, stock brakes work fine and the cars definately aren't show vehicles.

My quest here was to just give cross drilling a shot since I yanked the complete braking system (and every other imaginable part) off of a wrecked '87 240GL that the tow truck driver said I could have (personal friend of mine). A good point was made right after I started this thread by whitey saying that it's very unsafe. That was an excellent ------- point! I currenty live in the ozark mountain range and the more I think about it, the less likely I'm going to do it. That would suck so bad if I was coming down a really steep mountain pass and the brakes failed on me, one thing to have a master cylinder go out when you are driving on flat ground (which has happened twice to me on 2 other volvos I've owned), another to have your front rotors ---- out cause you were stupid and decided to ---- with a good factory product.

But the feedback I've gotten has been pretty good, maybe when I move back to florida and drive the volvo I have in storage there (my favorite one) then I might attempt the project (I'm sure I'll still have this extra set of rotors to play with).


I think the cracking of the rotors on a DIY job might be from the stress of the drill going into the rotor, a properly engineered and machined rotor should not crack during normal life/use. Cutting slots sounds a bit tricky, might just say screw that and only go for the cross drilled effect. I would think the only thing one would need would be a template to follow for the drilling pattern, basic math in effect. I wouldn't do something like this on a ghetto level, I would be using my drill press and whatever proper tools to make it work, if I do attempt it; expect a write up

My brother recently got cross drilled on his eclipse and I have a friend who just switched over to drilled/slotted on his '02 trans am.. only time will tell if those rotors hold up (both are ebay purchases )

god damn you make long posts :P

I read a story about this guy who worked at a track, and this dude came in with a volvo or something with home made cross drilled rotors, anyway, One of the rotors broke into like 100 pieces and the other rotor hat tons and tons of small cracks in it. But the thing was the rotors had like 100 holes in the each, there was way too many holes and that totally reduced the integrety

If i were stupid, I would drill maybe 4 holes per rotor, but not more than that. and i don't see why you wana put cross drilled rotors o na damn volvo, wtf.

The volvo braking system is not prone to failure, it's actually quite advanced in comparison to import/domestic systems of it's era. I wouldn't put that many holes in it, use a 1/4" (or smaller) drill bit - something that wouldn't break on me hundred times before the job was done, but also something small enough to make small sized holes. I would get a formula kickin, just do a proper pattern, I can't tell you the design right now, not that close to the project yet.

As I illustrated in a couple posts on this thread, I have a full (4) set of rotors that were free and just hanging out on my front porch right now (awaiting sand blasting, then going to get a nice high temp coat of black paint). I wanted to try something new, Jeff and Whitey put twin turbos on their rides, my claim to fame might be cross drilling some rotors (well maybe not, but it was a good effort). Nobody is going to see these rotors past the stock rims (if I had some thin spoked chrome rims, that would be a diff story), I'm not going for the "look" at all. The basic performance of these brakes is far superior to any other car I've been in, I've pleased with the way they work stock. Soo, I have the resources (4 functional rotors), I have the right tools, I have the time.. just thinking of giving something new a shot. That's all.

ask any of the ladies, my posts aren't the only thing that's long

Thats funny.The site has only been aroung for about 1 1/2 years.

Never asume that anny car is rice proof!

Just buy some dude.Why risk dying?

Seriously.....

I had dilled rotors on my old Civic with the same set of brake pads for like 4 years. I have no ------- idea how those brake pads lasted so long. They were VGX pads with some cross drilled rotors I got from Summit back in the day. I am a firm believer in cross drilled rotors. I have a set of drilled/slotted rotors for my hatch and my truck needs brakes BAD, so I'm getting a set for that too. It seems to work good for me....
