basically your brakes (4 pots) are crap, brembos are better and so are ksports/d2 not a lot to choose between either.

for the record and forget everything else, what do you want to know??

when i went to replace my discs the above happened, rather than get them helicoiling,buy new discs and pads and repaint it was the same price to replace with d2s which are identical to ksports just a different sticker on the front. so i did.

as i run 18 inch wheels i bought 356mm kit and i have to say its slightly better than brembos but not vastly so and i put that down to the increased size.

so for me id go for ksport/d2s and thats from someone who has tried both setups with identical pads and you also get braided hoses in the kit.

and change the brake fluid at the same time.

does this answer it ???

and just to add if the brembos hadnt got above bolt issues would i have swapped them?? no but it was cost effective to as i sold on the brembos

Quoting John Felstead:

With regards to the K sports, you may have 8 pots, but the surface area of those 8 pots is almost identical to the WRX 4 pot and less than OEM Brembo's. The K sports have two small leading pistons working on the area of the pad that provides the main performance of the pad, which will give less bite from the pad than the larger leading 4 pot piston. You will get a better performance from a 6 pot caliper with properly stepped differential pistons. The equivalent D2 6 pot caliper has larger piston surface area and a larger leading piston than the 8 pot K sport, so gives better initial bite and more brake force for the same pedal pressure.

AP 6 pots have better differential piston sizing than both the K sport and D2, with 3 piston sizes in use to ensure the pressure on the pad is well matched to the requirement to provide less taper wear and give a better match to the required pressure increase as you move away from the leading edge of the pad, which is where all the work occurs. The D2 6 pot has 2 small and 4 large pistons per caliper, so the pressure required is less well distributed than the AP, but not too far away, the K sport has 4 small and 4 large pistons per caliper, which gives a less even pressure match across the pad length. This means the AP will give the better brake feel and modulation, with the D2 6 pot next, the K sport a bit further away.

With regards to piston surface area, pad surface and the total brake torque resulting from that, on a 330mm disk the D2 6 pot gives the most total brake torque, K sport next and then the AP 6 pot last. None of these give as much brake torque as a Brembo OEM caliper on a stock newage disk. Even a 356mm AP 6 pot kit gives less brake torque than an OEM Brembo setup. Where the AP, D2 and K sport win is in handling the elevated temperatures seen on track.

There are differences throughout the Subaru range with regards to the master cylinder bore size, and also pedal ratio, this will also influence the amount of force required at the pedal to give the required brake force. So a brake kit on a classic will work differently on a Newage STi, Newage WRX or Legacy. And we haven't touched on brake balance matching for the rears, or the way the ABS system will work when you change that balance.

Helicoiled all mine for the grand total of £5 and been perfect ever since! Steel threads on steel bolts now with a touch of copper grease. Never been an issue again.

regarding the brakes-heres my 10p worth...........

cost isnt really the issue BUT what you get for your money is-let me explain

a USED (nearly 10 year old) set of front brembos will be about £450 then if you have your head screwed on you will want to at least stick on NEW uprated discs and NEW pads (£550-ish)

http://www.godspeedbrakes.co.uk/~god...?id_product=28

http://www.godspeedbrakes.co.uk/~god...?id_product=86

along with a decent fluid (£20) and whilst your doing it you may aswell uprate the hoses too (less than £100)

so thats an outlay of (give or take) £1100 which will be fine for a fast road car BUT for not a great deal more money (£100 or so) you can have a a NEW k-sport kit with NEW (not 10 year old) calipers not painted in flakey pikey gold paint

see here

i based the price on the kit with ds2500 pads

http://www.scoobyworld.co.uk/catalog...oducts_id=2146

if the difference was £500-£600 then i would suggest brembos but as its the price of a night out then i suggest the k-sports

im not saying that they give better stopping power as i dont honestly know-what i am saying is surely something that is new is better than something that is 10 years old
