I have a 1988 subaru vortex turbo 4WD and was wondering if i can use the discs and calipers of it and put them on my corolla to make it a Disc brake rear end? :dance:

If you have enough money, of course they will.

 

If you want to do a cheap easy conversion, definitely not.

 

Why do you want to put a disk rear on a 20?

Get out a tape measure.

 

Get underneath.

 

Look at mounting points on corolla and vortex.

 

Compair.

 

Consider diff ratio's from both cars.

 

Consider Custom diff that will have to be made.

 

Vortex Rear diff isnt solid i don't think.

 

I doubt ull get much more than that off the internet..

i was only using the disc ans the caliper (not the diff or the hub) and i was thinking going to disc rearend due to was told disc is better than drum

Being someone who has done 200 odd motorsport events in a KE25, you don't need a disc back end in a 20 series. Not while you're still running a K motor. The buggers only weigh 900 odd kgs.

 

It's money better spent elsewhere.

point taken, will spend money on something else

you can get road legal stainless steel braided brake hoses too. i intend to do this. less expansion in the hose, more pressure into the caliper

I want some of these too. If for nothing else, to look more bling. :dance: But there are other things I should probably spend money on first. Like new tyres... And another set of rims!

 

Nick: are you getting those spacers? I think I'm going to be interested, just so that I can get more rims to fit on my car...

Back on the topic, as Redwarf said, cost-vs-value, there probably wouldn't be much advantage in putting rear discs on a car that's fairly light.

 

The front brakes do most of the work. The main advantage of discs over drums is cooling, not so much braking power. Well, and I suppose discs are less maintenance in theory (I found even the auto-adjusting drums I had weren't all that flash at adjusting themselves). So unless you're doing a lot of hard braking over and over again, I'd probably say to stick to the drums.

 

And as Nick said, good pads and fluid can help a fair bit, as can slotted brake rotors. And if you're really worried about overheating (my KE55 had severe brake cooling problems), the first step would be to get vented rotors on the front. If that still isn't enough, then go for rear discs.

powerslot makes great rotors, I'm not sure if they make anything for the older corolla. i know they make them for my gen. powerslot rotors, hawk hps street pads and good tires will stop you faster then you would ever want to stop. i lock my AA yokohama tires with my stoke brakes. on stock all season crappy tires it can do 60mph-0mph in about 120 feet. compared to other cars in its class thats pretty good. and i will attest that that is an accurate number :)

 

 

oh and yes, vented disc brakes will make a HUGE difference. even if they don't make specific ones for your car I'm sure that you can find some that will fit from a company or for the shopper on a budget the junk yard. :dance:

 

brakes work by taking kinetic energy (the car moving) and turning it into heat by friction. the more heat you can dissappate roughly relates to the amount of stopping power. the agressiveness and composition of the pads also play a VERY large role.
