    Default 87 - 88 turbo coupe front brake

    I have the opertunity to buy the front spindle, rotor calipers, & control arms. Are the rotors 11" (same as mustang) or are these the standard 10" ones? I want to upgrade from 10 to 11.

    Yep they're 11", the only difference is that they have the ABS exciter ring on the rotor.

    If you ever need new rotors make sure you get ones for a Mustang as the bird ones are more expensive due to the exciter ring.

    Can I use the mustang strut or must I use the turbo coupe struts? Must I buy any adapters to go between the metal brake line and the brake hose to use these on my 87 cougar? What brake hoses do I use?

    Either or, just keep in mind that the thunderbird strut is a PRC unit, so unless it's set on firm before you unplug it and pull it out of the car, it'll be mushy and crappy.

    As far as brake lines and such....I dunno

    I would think the thunderbird's rubber line would attach to your hardline at the frame.

    You will need an adapter for the right side (I think it was the right). You should use T-Bird/Cougar specific struts, as the Mustang one is a bit shorter. Your current struts would require spacers where it bolts to the spindle, as the 11" spindle is a bit narrower. And you'll use the TC brake hose - the hoses attach to the calipers differently with the 11" brakes.

    Is the factory master cylinder ok with the bigger brakes or must this be upgraded?

    I do not understand why we still have to use the tbird/cougar struts when the 11" spindle is longer than the 10". I was told that I could use either turbo coupe or mustang struts. Those that have already done this know what works and what deosn't.

    Fox struts are shorter? that's news to me...

    Factory MC should be fine, on my '90 2.3L LX I upgraded to 11" front brakes and never touched the MC.

    It all depends on your ride height. SN-95s are a closer match.

    I'm at stock ride height. I have stock fox mustang springs whcih actually raise my car about 1" when I put them in about 5 years ago.

    I understand about the fox struts being shorter because the fox mustang a arms are shorter also.

    Yeah but SN-95 struts have less travel than Fox struts.
