This is more of a curiousity question than a real question, keep this in mind. Say i wanted to upgrade to aftermarket honda civic big brake rotors, would this even work? if not, why wouldn't it work? Keep in mind i have the same lug pattern as a civic. I'm sure if i took my brakes apart i'd understand why or why not, but i don't have the time or patience (especially when i could ask here).

 

I've been here a while and I've never heard of anything like this at all. Best way to find out is to try it. Let us know how it works out.

 

If you used the honda brake rotors, you'd need to install honda calipers. Probably would need a custom made mounting bracket to mount those calipers to the stock mount points, along with brake pads to fit in those calipers. And while the bolt pattern for the wheel is the same, who's to say if the internal diameter of the rotor where it fits onto the axel is the same? If it isn't, you might need to hunt down some custom-made bearings that would adjust for the difference in internal diameter.....

Other than that, I'd say you'd be able to do it, but unless alot of what I have said proves unnecessary, for the price it might just be worth it to buy a good set of slotted or cross-drilled rotors *made* for our cars.

FYI civic bolt pattern === 4x100
GSL-SE bolt pattern = 4x114.3

 

and FBS have a hub/rotot assembly, civics its just a rotor. that is held on by the wheel.

 

What would be the point of this brake change?

 

Curiosity!

If the parts were easily interchangable, then the more readily available civic parts could be used. And they're cheaper too.

But as I said, I don't think it'd be worth the effort, because it would be a PITA to do, IF you could get it to work.

I suppose - though unless I was going to achieve braking improvement, I don't see the point. Maybe I'll go to work on cross mounting my rotory and installing a Subaru transmission - I'll build a 4x4 RX-7 for snow packed Kansas winters!

 

haha

a 4x4 RX-7 could be fun...

 

Maybe someone was refering to an Accord rotor. I have Accord rims on my GSLSE, so I know that there is some Accord that shares the bolt pattern.

 

Speaking of rotors - who makes a good cross drilled rotor for the 1st Gen. RX's?

 

Tirerack.com has some for the GSLSE. They are Power Slot and appear to be slotted not drilled.... I don't know if they have them for the 12A cars or not.

FWIW, I don't use crossdrilled rotors on my track car. I would recommend against ot for anything other than appearance.

 

I need to post some pictures of some brake rotors I got yesterday. I bought them from someone because I wanted the hats. The rotors are crossdrilled. These are huge rotors. They are factory made this way so you can't blame the failures on the drilling process. Every hole in the rotors have cracks radiating from them in varying sizes. The Previous owner said this happened after one track day on a 3000lb car with 150mph top end, on a 13" x 1.125" rotor... Avoid the drilling on a track car unless you intend to replace them often.

 

I ran for two years on cross-drilled rotors....no cracks....you just need a machinesmith that knows his metals to drill them for you after you draw out a pattern. Let him (It will always be a "him") decide how many holes, size of holes and the amount of holes to put into the rotor. He will know better...mine did....

 

They are horribly rusted because of sitting in the driveway unused for a while, but here's what drilled disc rotors done by a competent machinesmith look like after two years of hard driving, including one track day and one "kill the orange cones" day....shot taken last year after the wreck was put in my driveway from the pound....
