cross drilling and slotting???

[vr4boy]

where can i get this done? or buy them already done for an sw20?

[Jebus]

0800 Brakes, give them a call.

I havnt enquired but id say they wont drill/slot old second hand rotors that arent thier own. You can buy off the shelf drilled/slotted rotors as bolt in replacments, your usual stockists sell them, but 0800 Brakes are best.

Only one listing for SW20s, I dont know if they just use a single size rotor on most models or not. Show a listing for slotted and crossdrilled though



Dont do it to standard items. Crossdrilling will only make them weaker

The Masterton Repco have a pair in stock, thats for Gen 1 SW20. I bought the last set of plain slotted rotors for my car, they're bloody good.

But seeing your SW20 is NA, dunno if they make the smaller brakes with Slotted........

Hold on, you have an NA, why would you need slotted rotors?

[slighty_looney]

you could jst buy stanard new disks and get them drilld, iv seen it done on this old'r doods evo at my dads work , looks the part and hes neva had any problems with it

AKANE my car is in the process of a full rebuild, which will include a turbo convertion, going to do it all once and do it right, so the brakes are getting upgraded.
lookimg at getting some bigger rotors i have drilled and or slotted is all.

[Akane]

What year is your MR2? does it have the 92 bigger brakes?
If you're still on the older 91 brakes, you might want to do a brake conversion first to the later bigger brakes.

If you're on 92+, you'll find a pad upgrade is already good, but if you're motherfriggin' EXTREME >_<!, you might want a BBK (Big brake kit).

Now, are you EXTREME >_<! ?

mine has the older smaller brakes at the moment but am up grading to the later model brakes, and want to slot and drill the rotors as i intend on getting some track time once its finished.

General consensus is that its dangerous to cross-drill standard disks, as you stand a higher chance of fractures or cracks in the disk, leading to *very* unpleasant results at high speeds. Cross-drilling is a bit over the top for a road car. Slotted rotors should be the most you need (like in Akane's pic) unless you're planning on doing some very hard track driving. Much safer to buy disks pre-moulded with the slots in them.

Again, 0800 Brakes are the way to go.

[Akane]

I got my brake discs from 0800 brakes, make sure you get the DBA ones, not the China made ones I got.

I thought mine were brembos until I go pick them up.

Too much american forums for you!

Bad AKane, Bad!

J spec brakes are the same, whether turbo or Na, only difference is gen 2+ or not.

[Akane]

Hey, god bless America!

I got slotted my 1's in my BZ-T rolla from Zonllei in Manukau, working great

Surely slotted rotors are a waste of time on a road car, not to mention they munch through pads a lot quicker. You'd be better off spending money upgrading the callipers.
