BBK Opinion (VWR / B7 RS4)

[bluo]

Anyone know what would be involved in making these work on the golf gti?

Front will be easy providing you can get a bracket to suit them. The rears will be more bother... Electric handbrake.

Thought as much... The seller said he'd do a deal for cash so I thought I'd check first.

I've got the cash so I want to make the right purchase once and there seems to be sooooo much choice so not sure what to go for!

Second down. That's what I would get if I were buying again. AP calipers and AP discs.

Why 4 pot instead of 6? (Other than price).

Do you know if the red matches the vw red?

What power are you running?!

[bluo]

I'm in the process of upgrading hardware and hoping to be around 380bhp hence stating around 400 in opening post.

I'd like to future proof it a little if poss but open to advice.

Id of said 4 pots would be ample, but if you were going to spend 2.5k on them brakes on ebay, get 6 pot APs.... Maybe a tad overkill but still cheaper.

Ps give reyland a call for advice, he'll be able to offer loads with regards to track time etc.

Would you do anything to the rears?

Get Lambo/R8 8 pots with everthing needed re brackets, discs, pads etc for £2.5k.

Yes, add Audi S3 rear Calipers for their bigger pot and their larger discs (which are also  vented and not solid).

I've made my choice... AP Racing CP5555 6 pots... Thanks for allowing me to bounce ideas of you guys!

[Cossie Killer]

Nice....

[rich83]

They should do the trick!

Piston area is 2961.76mm2 per caliper

It's just BIG though, it's designed for a 32mm wide disc and they struggled getting a wheel over it so machined each half back by 2mm and used a 28mm wide disc.

Problem is thinner disc equals smaller diameter unless you want to spend GT team money

I have mine on order with BG Developments, I went for a variation on this with this kit as they have smaller bodied 'skinnier' calipers which help my wheel clearance.
From the AP site you can download a correctly scaled profile template that you cut out, stick to cardboard and can accurately check clearance.

Mine uses the CP5575 caliper. http://www.apracing.com/product_details/road_car_upgrades/factory_big_brake_kits/vw/golf_mk5_r32-front_6_piston_kit_cp5575m1011-2005_on.aspx

It looks like this:


It also uses strap drive discs which gives you a floating disc without rattling bobbins or springs which need to kept clean. Best of both a floating disc and rigid bolted system in one and a 32mm thick disc.

Pagid themselves recommended a new RST3 pad compound for the front (BG can supply this with the kit instead of the default AP404's for an extra £45) and an 'S' series pad for the r32 rears I have. The rear setup should be adequate.
Both of these are fine for both road and track day use.
