AP floating disk upgrade

[s.mac]

Group Buy thread now open

[s.mac]

I have ordered my 2 piece stoptech grooved rears which have a 7 to 10 day delivery time. I would like to order a set of front disks ASAP what's the best way to get things rolling?
Shall I pm thorney or do we need some numbers, I cant see there being much interest in a group buy but i'm happy to give it a go :whistle:

PF disc's last twice as long as AP one's

PF disc's are the best

[s.mac]

would still like a few more comments on PF v AP

I have PF and rate them but have not used with an AP kit, AP have very good race history and I have no experience with their disks

[s.mac]

I am happy with that if its not too long, I need a bolt set as well for the new disks.
looking around Thorney is the cheapest online, although when I have bought PF in the past these guys were very good on price

How about a group buy???? :thumbs:

I'm in need of some new front discs soon and if we can get decent discount then i'll get them with the group buy.

PF is the best :thumbs:

I am just about to order a set of replacement front disks for an AP kit

question to those who have used both PF and the AP disks

is one better than the other????

thanks Gorilla, Anthony at Simpson's has come back to me and its not an upgrade he advises for a street / track day car.

I think the standard CSL Disc are very good, not sure why
somebody has not done just a caliper upgrade to run with
the standard CSL Discs

they have in America :smt001

Anthony suggested sticking with the standard AP bell and just upgrading the disks to the PF disks (slightly more $$ than the AP disks)

The rears would be good as well, make the belles
out of 6063 hard Alloy, and hard anodize to 60 thou microns,
for the hand Brake shoes,
save about 2/3 kgs a side of un-sprung weight,
and still retain the handbrake.

Both Performance Friction and Stoptech do 2 peice Rear OEM size disks :smt001

Hi,

S.mac-Its a Disc / Belle combination, instead of the
CSL One piece discs.

I have 2 piece, belles etc, on the front.

I think the standard CSL Disc are very good, not sure why
somebody has not done just a caliper upgrade to run with
the standard CSL Discs.

Many after market kits go to 32mm or 35mm thick discs
as opposed the 28mm of the CSL ones.
That alone adds back about 1.2 kg over the 28mm thick ones.

The rears would be good as well, make the belles
out of 6063 hard Alloy, and hard anodize to 60 thou microns,
for the hand Brake shoes,
save about 2/3 kgs a side of un-sprung weight,
and still retain the handbrake.

Regards,

The Gorilla.
