Default AP 4 or 6 pot kits

Where's the cheapest source for a big AP kit? Inc bells, disks apart from pads?

preferably the 6 pots - must fit MY99 too

Any ideas?

ALL official AP "formula" kits come with pads (normally ds2500 Ferodo), as to caliper choice then for road use personally think there is little difference, however once on track the 6pot offers greater abilities.................

p.s. don't forget to do something with the rears to "balance" the car................

Alyn - What would you recomend for the rear to "balance" AP 6 pots on the front?

Do you not go with the theory that there is more weight transfer to the front of the car with bigger front brakes so the rears are less stressed post mods than before?

Or by balancing are you talking about reducing the braking from the rear?

Or are you just trying to sell more rear kits...... (laugh!)

Front Rear balance is covered at this site in a lot of detail

the weight transfer is exactly the problem, just not in the way you describe.................in brief, you actually need to uprate the pads (at a minimum) so that it increases the rear braking force, "pulling" the rear of the car down and keeping it 'flatter' under hard braking..............this has the effect of reducing the weight transfer allowing MORE braking effort thro' the front tyres (which are the limiting factor)

if you don't it actually allows the rear tyres to 'lock' far easier, overloading the front tyres and actually reducing overall braking effort!!

hope this helps, alyn - asperformance.com

Tyre grip stops the car and controls weight transfer.

larger discs (for heat purposes) adds more brake torque but usually smaller piston specs are used to reduce clamping force, so that brake balance is not changed. If piston spec is not changed then you will probably increase braking distance because the rear tyres contribute less.

If you uprate tyres to slicks then more weight transfer and you need more front braking.
