Are front legacy H6/specB brakes an upgrade over WRX 4pots?
There is a general opinion that front WRX brakes are undersized. I wonder if legacy H6/Spec-B front brakes aren't going to be a big improvement? Legacy rotors are 316mm/30mm compared to WRX 294mm/24mm. So the difference is easily noticeable, legacy rotors are nearly as large as STI rotors (326mm/30mm). Thanks to being thicker they are going to be much more fade resistant. And thanks to larger diameter (+22mm) the braking torque should also be much improved.
The only downside I see is caliper design (2large pots vs 4 smaller ones) - but is it any downside apart from how it looks and a bit inreased weight?
Why isn't it a popular modification, since legacy h6 calipers can be bought cheaply? Is there any downside that I don't see? Is there anyone who swapped 4pots for legacy H6 front brakes? Is it a p&p swap?

On www.uklegacy.com people are usually advised not to swap their 316mm spec.b brakes for 4 pots
- there is a conversion kit that allows you to use WRX type 4 pots with larger discs if you want to keep the 4 pots - might be a Godspeed kit!

4pots and legacy 316mm brakes seem to be comparable in operating costs. A set of 294mm or 316mm casual discs' cost is about £80, cheap pads £40 or some competition pads about £120 (M1155, RC5+) - total cost of 120-200 pounds per set. For comparison godspeed discs are £300 and pads probably at least £150.
I think that better option would be to go the STI golden brembo way. But still I am thinking about legacy calipers and discs, because they seem to be much cheaper and nearly as good as STI brakes, at least in theory.

Sorry I didn't make it clear - yes the Legacy 316mm brakes are an upgrade over the smaller WRX discs with 4 pots. As long as the sliders are working properly there should be no problem.
I have done the swap on mine (JDM Legacy 2.0GT spec.B) to STi gold Brembos all round - mostly for looks rather than needing any increase in braking power - which I am not entirely convinced is really noticeable if the sliding caliper brakes are in good condition

Useful info, thanks for your input.
Another const of H6 front brakes seem to be lower availablility and higher prices, compared to 4pots, of braking pads (for example I don't see OMP pads for that caliper).

2 different brands of caliper on the spec.Bs - could be Tokico or Akebono - lots of quality manufacturers make pads for them EBC, Brembo, Hawk, Performance Friction...

But maybe just because they are comparable?
Godspeed looks really nice, but if you compare the cost, they are much pricier.

I found no significant difference.

Thanks for your input lads.
Mick, could you tell me:
- are sliders a servicable part, can I buy them new (are they available, how much?) and replace them in second-hand calipers?
- do you know if stock wrx hoses are long enough for the spec-b calipers (it seems that mounting points are in different loactions on both types of calipers)?
- I have read somewhere that tribeca front calipers are exactly the same as spec b calipers, can you confirm that?
