is their a kit to convert the rear drums to a disc brake system?

my old 94 probe gt had 4wheel disc abs and i want my 03 lancer oz to have rear discs as well.

can the dealer do it or do i have to take it to a tuner shop. i know of only 1 in san diego that can possibly do it

I'm not sure how this will cross over, but my 03 Eclipse RS has rear drums. A common swap for us is to use GT or GTS rear discs. An even better upgrade that the GT/GTS folks use is to bolt on Evo Brembos...they supposedly bolt right up. So, I don't know for sure, but you might look into bolting an Evo setup onto the Lancer, or you might be able to use a 2000-2005 Eclipse GT or GTS rear setup...

To answer your question, no dealer would touch a brake conversion. They'd be opening themselves to lawsuits if something failed. Talk to the tuner shop, or just do it yourself.

I realized something after I made my last post in here. I guess some of you may have 4-lug hubs/wheels...for those that have 5-lug, the Eclipse swap or Evo swap may work. If you have a 4-lug setup you'd have to swap out the hubs (and maybe other parts as well...I'm not sure on the Lancers for sure.

I have heard that putting discs on the rear will cause them to lock up if you jam the brakes or something. Something about them not working properly since they are made to be drums.

Usually, a disc/drum setup has some sort of proportioning system built in to allow the front and rear to apply evenly. On the 3g Eclipses I haven't heard of any issues with people swapping the drums out for discs, but the Eclipses also use the same master cylinder for both set-ups, so it's hard to tell how Mitsu biased the brakes on that car without really diving in to it. I'm not sure how the Lancers are set up either, but looking into this could explain that problem...

What about swapping the front discs to the rear and then just getting some powerslots or something for the front. I've had this idea for a while, but am nowhere near brave enough to try it on my only car.

Agree w/ Amby.

You always want the front to be slightly bigger than the rear, unless you like heavy rear brake bias. Basically, locking up the brakes = inducing oversteer-like tendencies.

This sort of thing happened to me driving a beat up Olds Cutlass Ciera. It had severe air in the brake line. Under heavy duress, the front starts to grab before pulsating. Then, the rear starts to grab before all 4 calipers start to pulsate. Finally, the rear grabs so tight that the car still had momentum. The rear swings out.

Could the rear bias be fixed with proportioning valves or anything?

I think that might screw up the braking.
