Fantastic 57 Report post Posted January 2, 2017 I was concerned with safety, so I opted to upgrade my brakes using the kit from Vintage Venom. Using their adapter I installed '04 Cobra rotors and calipers. To allow these larger calipers to fit, I had to use 17" rims. I chose bullitt anthracite rims, 17x8 deep in front, and 17x10.5 deep in back. I still like the idea, but I will have to do more work to get the this set up properly. I can drive the car, but I am fearful of the possibility of the rubber inadvertently bumping a fender or quarter. I am also unhappy with the braking system, and I suspect I need to change the MC, perhaps with a hydroboost setup. I would like to read more about what others have done with theirs. photobucket 4 Selmadox, SHosting, yapedVem and 1 other reacted to this Quote Share this post Link to post Share on other sites

RPM 1,190 Report post Posted January 3, 2017 With a proper alignment it should not be an issue. How much caster do you have? Make sure the wheel base is 108". A one inch master cylinder is usually recommended for four wheel discs. Quote Share this post Link to post Share on other sites
SWPruett 83 Report post Posted January 3, 2017 Agree with RPM's recommendations! Just a bit of love on the alignment can make a HUGE difference in road manners and the 1" M/C bore is standard order. I really like the look of the wheels you have and the size seems to work well. Can you provide anymore details on them (e.g., offset/backspace, manufacturer, etc.)? Car looks really nice as well!

SM69Mach 68 Report post Posted January 3, 2017 I agree with the above. I have a similar set up with SoT Cobra Conversion set up and 17X8 and 18X10 Bullitt wheels. With as low as my car is I don't have any rubbing. I am running a 1 inch spacer on the front because of the BS of the wheels, but have ran it that way for years with no issues.

rwcstang 201 Report post Posted January 3, 2017 I would Invest in a Good Brake Booster too if you haven't already. I have the VV kit as well but my wheels are 18x9/18x10. The Front/Rears tires did rub when doing hard turns or going up speed bumps. I had to roll the Fenders, which solved my problem. Also, as suggested above changing the Master Cylinder to a 1" bore should help. Quote Share this post Link to post Share on other sites
lanky 44 Report post Posted January 3, 2017 rwc stang: what is your front wheel backspacing? When I win the lottery and purchase wheels I want to see if I can get away with 17x9's all around with the same backspacing F-R Quote Share this post Link to post Share on other sites
rwcstang 201 Report post Posted January 4, 2017 @Lanky I run the 99-04 wheel setup since my brake VV kit it requires me to use those type wheels. You can run 17x9 Modern Wheels all around but you will need a spacer or wheel adapters. Unless you have the original Disc/brake set up, there are wheels that can work but can't help you with that since I never had another wheel setup.

1969Fstback 58 Report post Posted January 4, 2017 I am running a 99-04 wheel aa well. Same as rwcstang. 18x10 in back 18x9 in front. Front has 5.95 inch back spacing. I have the mustang steve conversion with 2007 gt brakes. I converted drum spindles to disc which adds like 1/2 inch then a 1 inch spacer. Quote Share this post Link to post Share on other sites
lanky 44 Report post Posted January 5, 2017 Ok so the wheels are for 99-04 got it, 5.95 backspacing. I actually am already running 1.5" wheel spacers, but would like to get rid of them just for safety. When I do buy wheels I like knowing others have run a similar size/backspacing setup with success. No tire rubbing for you two? What tire sizes are you guys running? When I go 17x9 I am hoping to get at least 245 or 255 up front, I have 235 now.

They did rub when taking hard turns or going over bumps, Rolling my Fenders solved that issue. Quote Share this post Link to post Share on other sites
Fantastic 57 Report post Posted January 5, 2017 I am hoping to try out a set of normal '04 Bullits to see if the fit is better. Rolling the lips is going to be tricky since the car is already painted. Every step is a new challenge. Quote Share this post Link to post Share on other sites
1969Fstback 58 Report post Posted January 5, 2017 I'm running 275/35 in back 245/40 in front. I haven't had any rubbing with 2 inch lowering in back and about 15 up front. I need to trim front spring. I did have to trim the bump stop metal piece that was hanging out cause it was hitting the rim. Quote Share this post Link to post Share on other sites
