C4 or C5 Conversion

[Leadfoot1]

Markm66,



About;

'From what I remember when doing my C4 conversion, the C5 rotor sets back less then the C4. So I don't see how it would ever come in contact with the stock control arm.'

That's what i tought too + the C4 rotor is a ''real" 13 inch and the C5 is a 12.7" and nobody i heard from had issues with the C4's...

Rizzo,

Sorry if i got you confused, i sold my '70 Chevelle and now have a '69 Camaro on the rotisserie. I'm basically building a back half car with a tri 4 bar set up in the rear with coil overs all around, so i have F-body spindles right now (drums and discs) that are still the same as yours i guess (A-body).

I heard i'll have a hard time getting more than 900psi of pressure without hydroboost so i'm looking at this too, heard of mustang cobra (year?) unit as a nice fit?

I basically want 13 inch crossdrilled/slotted rotors in front and 12" in the rear with as much GM parts in than cash out.

Now, wondering if your point of 'Tubular arm necessity' still applies to F body? They are part of my plan anyway (uppers) but i'd like to clear that up anyway (it might also help others!)

See, speedtech sells them, (Arms) but they don't even mention you need them to run their bracket and C5 rotors and calipers...
I will try to contact them i guess.

Lead.
