There are quite a lot of ppl in my area selling off their Red WRX stock brake kits/ calipers taken from their 06, 07 rex. Will these fit on our new WRX? Can we just get their calipers and fit on our existing rotors?

I don't really have any problem with my current brakes, but they do look "unimpressive". Why is it that the older wrx comes stock with the strikingly-nice 4/2 red brake calipers, while our newer wrx comes with smaller 2/1 ones?

I feel so short-changed. :mad:

I agree... Last years brakes were very nice and sporty looking. This years are just bland. Thought about painting them, but it doesnt even seem worth it.

front fits nicely, rear needs some modification. in fact already saw a 1.5R fitted with the red wrx brake kit of the previous gen. anyway stock brake is good enough for daily driving.

So does that mean that for my front wheels, I only need to bolt on the old rex caliper, and I can still use back my original new rotors?

And that for rear wheels, I have to change both my calipers and rotors to the old rex ones?

The reason I'm asking is that those 2nd hand subaru 4/2 pot brake kits may have badly worn out rotors, so if possible, i would rather use my own stock ones on the new 08 wrx.

the front rotors are larger on the 06/07 models. everything will bolt right up, but you'll have to get 06/07 pads and 06/07 rotors to work with the 06/07 red 4-pot calipers.

the rear rotors are the same but the rear calipers won't fit anyway unless you fab a new knuckle setup using a mix of both parts (we have a different rear setup than any previous years).

if I was made of money I'd go and figure this out myself but I can't do this on a daily driver. maybe someone else can take the dive for all of us? I'd love to get nicer looking brakes.

Oh dear, I'm glad I didn't go ahead and purchase one of those used ones then. Else I would have been stuck with a rear caliper that wouldn't fit. Thanks for the info man.

It won't be long until someone makes a retro fit kit for the rear (if it hasn't already)

Also if changing the fronts out I would be putting on new rotors and pads anyway.

the fronts would really be all that you would need, just change the lines pads and rotors to and itd stop on a dime

technically your only advantage would be from better pads and lines... the older calipers perform equally to the newer ugly ones.

I'm only going to do this if I either win the lottery (I never play) or find them on a car in a junk yard.

I wonder how much more (if any) the late model rotors and calipers weigh than ours. This "upgrade" could be a downgrade if they are significantly heavier.
