this is the quesiton that i wanted to ask...i am going to be doing the WRX/Legacy GT front brake conversion to my RS to increase the swept distance and was also hearing rumors about the legacy GT rear Brake swap to increase swept distance as an option. Does anyone know if the shields are avialable seperately or just with the knuckle?? it's kinda strange they are tack welded...i would have expected hold down screws. Well anyhow i am gonna use up my stock brakes before i worry about this. Keep the info coming guys. Good job on the install, looks KILLER!!!

I or one or the PR guys might have been where he got the Idea as we have been doing this mod to the Imprezas ever since the '00 Outback came out. Mind you that the regular 2000 (New style) Outbacks all have that rear breaks, not just the H-6.

This is a worthwhile mod as you will notice that the car breaks mor level instead of "nosediving" when you slam on the breakes.

I have been talking to Power Slot and they are almost ready to release (if they haven't already) this rotor.

Im waiting for it to order the full slotted set.

Good luck guys.

The rotors for the legacy swap are only $72 each if you pay MSRP . Keep in mind the Legacy Swap is more expensive because you are also changing to a

A) vented rotor
B) larger calipers with larger pads and a larger pot

The legacy setup costs more because you need the calipers as well . The rotor size on the legacy swap is marginally (1mm) larger than the stock rear rotor, but the pad is much much larger. I'm going to have to do some calculations as to how much bigger next time I have the rear apart. You not only increase effective swept area but you also increase the force applied to the brakepad due to the larger pots. Until we have concrete numbers from both setups, it's anyone's guess as to which one is better in the long run. I'll keep my vented legacy rotors and my brake shields either way though .

The rotors are $50 a piece at Subaru parts. The brackets unfortunately are also about $50 a piece.

Taking this concept to an extreme is a kit that uses 318mm rear discs with the stock caliper that will supposedly fit under 16" wheels (unknown if that means stock or 16x7 RS rims, or only 'select' 16" rims)

I saw it initially at Graham Goode
http://www.grahamgoode.com/cgi-bin/p...page=tarox.htm

avsport.net is also selling the kit, but I have not received a response from them about the price yet, but if it's 472 Pounds at GGR, I'm not hopeful that it would be under $600.

But still, 318mm discs in the rear would sure look better, but it looks more like the Outback rotors will win out (for 1/3 the cost)

Lightbulb Agreed Brian.

Brian,

I agree with you on the Legacy Turbo rears. Pad and pot are a good deal larger than stock.

These rear brakes were used by Prodrive in the early Legacy rally cars and in the verI to III (I believe) WRX overseas.

I also don't agree with anyone that states that it's great to upgrade your front brakes and not your rears. Not saying you should get vented discs, but some sort of upgrade is needed.

I spoke with a 12 year SOA veteran this pass weekend at our meet and he got into a long discussion on brake valve proportioning, master cylinder size and brake pressures (most of which lost me completely!). The concensus was don't upgrade your fronts unless you upgrade your rears... it wont stop the car any faster, but it will create much better straight line stability and increase the brake system longevity.

That is all.

-Mike.

Mike, I can confirm that the Ver I - III STi rear brake rotors are the same size and the caliper is the same. The two pot rear conversions for the I-III were caliper and bracket conversions, keeping the same rotor . So, if someone wants to read between the lines....

you *can* have two pot rears without hub or bracket modifications on an RS .

don't believe that this question has been answered:

"So, what is the risk of having no brake shield? Will this affect brake cooling or does it just protect from roadkill?
Can you buy the Legacy brake shield and install it? "




Thanks

anybody know what parts I will need to do this on a GC8? Same thing isn't it? Same part numbers? Rotors and brackets, right?

Anyone know how the increased rear brake bias is going to affect handling? Since more rear bias is supposed to increase oversteer, there's got to be some difference right.

I've been considering this one ever since I did a WRX front swap.

One more question, you said you had to take off the rear shield and that it was spot welded, did you replace it or just leave it off?

Thanks!

What if, after the rotor upgrade, we put new 4-pots on the front and shift the current 2-pots in the front to the rear ? Is this possible ?

Later...AH

I pounded the edges back. With the stock 10.3" rotor, it curls around the edges. With it pushed/pounded back with the 11.4" rotor, it is flush with the outside rim of the rotor.

News from the battlefield... Bill Harvey and I attempted the H6 rear brake conversion on his MY98RS. It will not work! The MY98 caliper has one bolting pin and one sliding pin whereas the MY99-02 Imprezas have two bolts holding the caliper to the bracket. If any MY98 Impreza or Forester owners (possibly even Legacy GT, not sure) want to do this mod, you need new (or used) calipers as well as the bracket (which is the same bracket as used on the WRX front brakes by the way ) and rotors. Picture below:


This pin bolts in on the MY98 bracket and just goes into the housing of the MY98 caliper and stays there, no bolts/nuts. The MY99-02 has the pins go through the bracket and bolt into the calipers. There is no provision on the H6 caliper bracket to bolt this pin into (ie: no threads). You could "arrange" something I suppose, but it's not a straight swap from MY98 => H6 whereas it is from MY99-02 => H6.

Bringing this back from the dead...

Does anybody have any real world experience to answer DoorKnob's question?

I'm working on getting the parts to convert my L wagon up to h6 braking status. However, I'm a little leery of this due to the fact that this brake configuration was designed for the Legacy chassis, not the Impreza chassis. I'm also worried about the bias due to some mention that my brake proportion is already different since my car started out from the factory with drums instead of discs.
