I havent owned a cobra with a power booster, and quite frankly wouldnt bother with one! I have AP 6 pots PN#5570 front calipers and AP 4 pots #5100 for the rear on 330mm front rotors and 295mm rear rotors, using Pagid RS5 pads all round plus AP Master Cylinders, these calipers I consider superior than Wilwood for one reason they have integral dust seals and are designed for road conditons where few of the Wilwoods have dust seals, plus the AP is considered by factory race teams to be a more stable product.

I will come honest I really wanted to see the yellow AP logo throught the knock on wheels..........!!!

I believe with careful selection of hydraulic brake components eg piston sizes etc and Brake pads which have different friction compounds there is no need for a power booster, but I guess I am a die hard enthusiast that will put up with a heavy steering, hard brake pedal monster.
