I tired to fit sti rotors and 205 calipers. You need to make a wonky bracket to make it fit. One guy paid to have it done, but he said by the time he was done it cost him more than most other available bbks. If you really want an off the shelf solution, it will still cost you. If you look at my posts in the front 205 caliper thread, I came up with a solution using WRX rotors hats. Revolution is selling these cheap on ebay. I also posted links to a company that can make custom rotor rings. So you could get a 2-piece rotor setup that would fit the 205 calipers. Still would consider shaving some of the material off the ears just to keep clearance on the ball joint. I think it would be around $120 a rotor ring. Its really not that bad in the scheme of things.

Can you re-post the link for the rotor rings?? :D

I'll see if I can find the link. It was bookmarked on my old machine.

i have sti 04 rotors with wilwoods and they fit without a spacer behind the rotor.
I will be doing some more testing with the coil all the way to the bump stop but when i checked clearance with the bbk on, there was still around 1.2mm clearance with the shock 2/3 under compression. Note, this is clearance with full lock l/r and straight all under compression. Then the car started lifting so I backed off lol.

If I get worried, then I'll grind a bit off the ball joint, but until the compression test is done, then I'm happy with the BBK as it stands with the sti rotor.

Reason why no spacer behind?
1) making a thin spacer unit with a hubcentric ring is not an easy thing to do, even for an engineer. Apparently the aluminium starts wobblying when you get down to 3mm thick.
2) In NZ, you can't run a double spacer, even with extended wheel studs. As I am running a 20mm spacer on the front, the spacer behind the rotor was a no go for me.

Are you using ST205 calipers?


No, I'm using the Porsche/Brembo setup. If I'm going through the hassle of upgrading, I want to make things easier on myself, not harder.

i installed st205 brakes all around its quite easy but get ready to spend your money. heres a list of what you need and what to do and what i spent wich is 320$ without the rotors and calipers.

1. extended wheel lugs 95$(A.R.P) local or ebay
2. 2x 20mm spacers 80$ ebay
3. 2 x 4mm spacers 15$ ebay
4. SS lines (i didnt do it but i made a bracket to extend the stock brake line)
5. ST205 rotors in your case because you dont have them(mine came with the half clip i bought)
6. Brake fluid (obv)

heres what you do when you have everything

1. go to a machine shop and ask to mill down the rotors down from 315mm to 305mm and skim off exactly 1mm off each mounting point on the calipers (50$ for rotors + 90$ for calipers)
2 use a dremel and cut the 4mm spacers to make them fit inside the rotor. it really needs to be 4mm. 3 will knock the lower balljoint and 5 wont make the rotor centered with the caliper's pads
3. use a piece of metal to make it hubcentric

if you need a guide on how to install them just tell me

In this page I mention one place that does the rotor rings. See the post with the dimensions. Revolution on ebay has a bolk lot of wrx hats. They can be ordered separate from him. Or you can look at the option in the post above. Either way, you will be spending more cash to do this.

Thanks guys! :D I'm not afraid to spend what's needed to get all four calipers to work :wink:

so the work has been stated as to how this is done and you still are willing to commit to this based on what is perceived as an emotional investment (IMO). Trust me, I thought about this just to have Celica on a caliper, and I have been through a number of measurements and testing to see whether this would work. And it wasn't worth trying to make it work at the end of the day.

Seriously, st205 brakes are decent, but not fantastic. You'd be better off getting a brake kit that bolts straight on instead of re-inventing a brake kit which may or may not work. Save some money and go with something that works out of the box.

And wait for the fun you'll have on the rears with the hub spigot being a different size. I ended up buying st215 rear hubs with the 55mm spigot hubs so I didn't have to piss about with a 0.7mm shim..

I have st205 calipers and discs on my st165

Its not a major. Caliper adapter, disc spacer, longer studs. You may need longer brake hoses. I had some braided ones made anyways.

Have you been able to certify it as it is? or is it not a road car?

Says he's using Evo8 rotor & 205 calipers

Puffy is using a custom bell with a 355mm rotor that pushes the st205 caliper out to clear the st185 mounting points.
Easy to understand that he is also using a caliper mounting bracket as well.

BMT has contacted me regarding the brake setup I have resolved with MRP Ltd.
With this request, I will be investing some time into getting the right information to people on my journey around this whole BBK design and stuff I learnt.

Will require some time to write and assemble, but will be worth it. Dimensions, measurements and photos will all be included :)

Cheers
