Cross-drilled rotors

georgeperez38 · Post by **georgeperez38** » Sat Jun 12, 2004 8:00 pm

Hey everyone. Thnaks for the help with the tire size question. Now I'd like to know of a site/store that can sell me a pair/set of cross-drilled rotors for a 93 Legacy L (FWD). I have a standard suspension, 16" tires.
Thanks

I wouldn't get cross drilled rotors. Most people haven't had very good experiences with them. If you want high performance rotors get gas slotted ones instead. Where as I've heard nothing but bad things about cross drilled rotors, I've heard nothing but good things about gas slotted rotors.

I hope to get some frozen slotted rotors the next time I need 'em, personally.

You may have a hard time finding any performance rotors for your stock front brakes. It may be a good idea to first upgrade to WRX front brakes, which should fit behind your 16" wheels. If you're still unhappy with braking performance, it should be easy to find performance rotors (like Matt says, slotted is better than drilled) for a WRX.

I have cross drilled/slotted rotors on the fronts. Used to have them on the rear, but upgraded to rear turbo brakes.

I have had nothing but excellence from the cross drilled rotors. No warpage, no uneven wear, no problems at all.

They were brembos (oem quality) that i got on ebay a few years back.

How involved is the conversion for the front breaks? And where is a good place to find them?
Thanks vrg3.

The conversion is easy, I'd check NASIOC for guys selling off their OEM brakes. Only get the fronts though, our rears are already better then the rex's rears already.

Well, with MTK, that makes one positive review of crossed drilled rotors that I've heard.

The conversion is super easy indeed: http://www.legacycentral.org/library/brakes.htm

It's pretty much just the same process you'd go through when doing any thorough brake job. No modifications are needed.

I second Matt's suggestion to look on NASIOC. A lot of NASIOC members upgrade their brakes and need to get rid of the stock set. eBay's another place they unload them sometimes.

The thing that makes me most wary of drilled rotors is the large number of complaints I've heard or read about them cracking when driven hard.

Most of the problems with cross drilled rotors are because of the owners.

If you drive them hard, and don't drive them correctly, then they will get all cracked and messed up.

How many Ferrari's do you hear about that have brake issues when driven hard? Not many, because most of the drivers that actually use the car for what it was designed for, know how to properly warm up and cool down their brakes.

That is semi-true. I let them heat/cool gingerly for the first few thousand miles. Then i wanted to see if i could get them to warp, they never have. I might just be lucky.

Thanks for the link vrg3. quick question though: Why wouldn't I want to replace the rotors/calipers for the rear? Do the WRX calipers look the same as my 93 vintage (stock) calipers? (Do the WRX caliper's have Subaru stamped on the side?)
Thanks

Turbo Legacies have 10.4" Vented rotors. WRX's have 10.4" solid rotors.

The only rear upgrade to consider is the "H6" rear rotor upgrade, but those are solid not vented.

I think the H6 rear rotors are 11.4" just like the WRX front brakes.

He has a FWD n/a, so the turbo rears would be an upgrade.

Ok. Since I have the 93 L model (FWD) then upgrading the rear breaks to WRX would be good too?
Thanks for all the info guys.
If you hear of someone selling their OEM WRX breaks, let me know.

You'll gain pretty much nothing. The rotor is exactly the same. The caliper piston size is slightly larger 1.374" dia vs. the wrx 1.5"

But you could simply find a first gen leg wagon if you wanted a larger piston diameter. If you went with the wrx rear brake setup, you'd need to swap the caliper brackets as well as the caliper & you'd need new pads as well.

Ok, scratch the rear break upgrade. Still looking for the fronts though.
Thanks

Ok. I found someone willing to sell me their WRX OEM front calipers and rotors. What is a reasonable price for this? (Lets assume they are in good shape, no scratches, etc.).
Thanks

I think I paid 200 for the calipers & pads. I bought my own rotors new. I probably wouldn't pay more then 200 for everything.....especially since everyone's selling them now.
