Want rear Brembos?:icon_twis Yimi Sport Tuning and Boostjunkie Performance is happy to announce that we have just received a run of US made CNC machined adapter brackets to allow STi rear Brembo calipers to be bolted directly on to any LGT, WRX or Forester.

 

Here the details and pics:

 

Machined in the USA from solid billets of 7075 aluminum. Ultra strong and light.

Flash hard anodized to resist wear and provide great finish durability

Threaded holes are helicoiled to avoid any stripping problems when the calipers are removed/replaced

^+1 RacingBrake 316x18mm rear rotors are only $300 - why wouldn't they work with these Brembo brackets?

 

Personally I'd be a lot more interested in set of Brembo adapters that retain the stock rear rotor - it's plenty large at 290mm and the change in bias is small. Bias w/ STi F Brembo + std R Brembo kit = 74/26% F/R; w/ stock R rotor + Brembo = 76/24% F/R. For reference, stock bias is 78/22% F/R.

 

How many of these brackets would it take to make production worthwhile? Since you already have the design, just subtract 8mm in height and they're done.

Are your bias numbers from Ted's post? I'm pretty sure you know this already, but the bias percentages were incorrect due to the wrong rear piston size being used in the calcualtions. The main reason for the DBA and or Brembo hybrids is to retain the stock parking brake functionality while still increasing rear bias with the larger rotor.

Btw, I'll be installing mine with regular rear rotor with special parking brake shoes :)

Ah yes, I remember seeing that shoe walkthrough. Too much trouble for my tastes, besides I got a great deal on my DBA's.

Why trouble. I don't like extra 4 lbs. of rotating mass per side, neither added cost of these rotors is appealing.

Nope, my calculations. I was the one that pointed out the piston discrepancy.

 

Using the stock rear rotor + Brembo would reduce rear bias a little, but at a cost savings of $450 not needing DBA rotors. Sounds like a fair trade-off to me. :) Or one could just use the Subaru 2-pot rears + kartboy brackets and have more rear bias than DBA+Brembos: 73/27% F/R.

rotating mass is negligible on my setup with light weight wheels. That, and I believe small increases in performance like that are often shadowed by driving ability and experience. There's definitely more improvement to be had adjusting the nit behind the steering wheel once the basics are covered.

 

Either way, its nice that there are other options now available for those who want to go a different route.

I am talking about mass not driving abilities. Generally true, but that's orthogonal issue.

 

Also it's not just rotating it's also unsprung. 4 lbs. is a lot, as you probably know when shopping for wheels. I have lightweight wheels (15 lbs), lightweight tires (22 lbs.) and will be installing alu trailing arms soon. We talking big weight savings here when you add it up.

And I was talking about both;). Unspring weight, rotational inertia, all eclipsed by driving ability, IMO, at the amateur level.
