  1. do you really need Wilwood brakes?

    Factory Five Roadsters
    when my son and I attended the build class a few weeks back, one of the things that the instructors said is 'you don't NEED Wilwoods unless you're tracking the car...' - the stock Mustang brakes are built to stop a vehicle 2x the weight of the roadster... if you want shiny red calipers, then...
  2. Flip rear brakes on 8.8 solid axle

    Factory Five Roadsters
    I want to swap the brakes left to right on my donor 8.8 solid axle, so they're forward of the disc. I understand this will provide easier e-brake routing through the ears on the diff housing. Do I need to remove the axles for this, so I can unbolt and swap the caliper mounting plate, as well...

    Factory Five Roadsters
    Wondering if anyone has had success with doing a s197 axle 8.8 " and more so can we make the gt500 brakes 13.88" work with the 17 inch rims?

    Ask Gordon!
    Good day Gordon. I'm a happy owner of a set of your Koni shocks on my Coupe built primarily for track events. I have 11,000 miles and 4 or 5 years of 8 or so track events a year. At the start of each season and along the way I look hard at all the bits to make sure things are all good. I...

    Factory Five Roadsters

  6. Poor Braking

    Factory Five Roadsters
    Hello everyone, first time posting in the forum, hopefully you have some suggestions for me. Took the rolling chassis out for the first drive last weekend, and it ran pretty darn good overall! I am a bit concerned about the stopping ability considering the weight and how much braking is on the...

  8. Bleeding the Brakes with Hydroboost?

    Factory Five Roadsters
    Hey everybody, So I recently got finished with installing all new cobra disk brakes on all four, and also installing a hydro-boost system on my Mk 3. I've bled brakes on my different cars but not one with hydro boost on it. So recently what is happening is that i fill up the reservoir and and...
  9. Wheels/Brakes

    Ford Modular Engine Roadster Builds
    If I want to keep the disk brakes from a later model build (03-04 donor), do I have to go to 17" wheels or will 15" wheels fit? My gut feeling is that the bigger performance brakes from Cobra and Mach I models are 17" only.
  10. Brakes - Need some help/pictures etc

    Factory Five Roadsters
    Mark III, donor build, stock front discs with rear drum, stock master cylinder. The questions: 1. Do I use the distribution block or straight to front/rear brakes from M/C 2. If the above is true, do I plug one of the front brake outlets from the M/C 3. Is there a switch in the distribution...
  11. new rims bigger brakes!! suggestions?

    Factory Five Roadsters
    Hey everybody, So I have had 15 inch rims for a couple years now and I loved them. But I love performance even more. I have decided to move to a 17inch rim which equals more tire and brake selection all across the board. So, to all the autocrossers out there what is your recommended tire...

  14. Weekend Coupe plans

    FFR Type 65 Coupe
    For 18 months small oil and coolant leaks have had me “dabbing at the chin” of my car. I have plans this weekend to, with my friend Mike Aedo to remove the engine and trans and locate and repair both. The oil might be the rear main but Gordon Levy has been helpful in pointing to other spots to...
  15. Seeking Photo

    Factory Five Roadsters
    Anyone able to direct me to photos of Levy's rear brakes on an IRS car? Specifically how the aluminium bracket is mounted. I got the stuff and won't be able to be at my car for a few days and would love to have some visuals to think about it. I have a Pin drive read and swapped the rear...
  16. Wilwoods on the back

    FFR Type 65 Coupe
    Good day folks. When I installed Cobra brakes on my IRS equipped car, on which I also have a Vintage Performance adjustable rear sway bar, I had to move the caliper to the front of the spindle. I don't recall just how but it did involve some grinding on the spindle. I now have a set of...

    Factory Five Roadsters
    Hi Everyone, I’ve ordered my base kit with IRS and I should receive it sometime near the end of January. In the mean time, I am trying to spec out all my major systems. As for brakes, I’d really love to go with ABS power brakes. There doesn’t seem to be a kit available through any of the...

  19. ABS speed operation question for 94-96 ABS systems

    Factory Five Roadsters
    Granted I've only tested the newly installed 1995 ABS on the FFR with hard stops from about 30 mph, I can't see that it's preventing wheel lock up. I can still slide both front wheels. The sytem is passing power up self-tests and generates no error codes while driving. I checked the wiring...
  20. Hydroboost question

    Factory Five Roadsters
    There have been some excellent threads on using hydroboost power brakes but I couldn't find one question I still have. I am planning to run manual steering so the power steering pump will only power the brakes. Do I simply plug the fitting in the picture below? Any other concerns?
