Brake master cylinder upgrade? Reply #60 – March 17, 2014, 09:54:44 AM Quote from: TOM Renzo;430716It sounds like you are comparing a dual area to a single area BOOSTER!!! Please show a photo of the booster for clarification. Which master do you have 15/16 or 1 inch???? I do not understand what you mean by a spacer. If memory serves me the cobra booster is 205 MM duel unit. if in fact you have a duel unit that is perfect.That would be the 1 inch. Quote Selected
Brake master cylinder upgrade? Reply #61 – March 17, 2014, 09:57:38 AM Quote from: 1987tbird5.0;430704OK, '93 Cobra brake booster and master cylinder are in the car. I purchased an adapter kit with them that is basically a T with two short brake lines that make life easy when doing the swap. I still had to bend one of my original lines to connect everything, but it wasn't difficult. My brakes feel so much better than they ever did before! My car really stops faster, just from this upgrade.And for those that have wondered . . . the Cobra booster is 1 inch narrower around and 1 inch longer, give or take 1/8 of an inch. The length measurement is from firewall to for the MC. The designs are different in volume by quite a bit. The Cobra booster has a lot more volume, the T-bird booster has a spacer that decreases the booster internal volume.Yeah, much different. If I had to do over, I would have attempted to change out the MC and booster before doing my 5-lug conversion. This simple upgrade could have saved me a lot of time and money. As far as lugs go, I would have been happy with just 4. Quote Selected

You have a much better selection of wheels with 5 and if you are putting down any type of hp you need the extra lug!!I don't know the specs of the 93 Cobra booster. I suppose it could be googled. All I know is it works really well, and is virtually a bolt on change out. As far as 4-lugs go, I don't plan on having any more than 350HP. 4-lug would be fine. I have found as many 4-lug wheels that I like as I have 5-lug. Snowflakes from a TC would look pretty good on my car. Quote Selected

The difference is in the bolting pattern to the firewall as it is the same as our cars due to the Fox pattern. This keeps you from having to slot the holes in the firewall on a Fox car to install an SN95 (94-98) or New Edge (99-04) style booster.The 93 Cobra MC is metric threaded and has a 1" bore.Darren Quote Selected

Reply #70 – March 19, 2014, 12:10:46 PM Tom,The stock booster has an projection off of it where it bolts to the firewall similar to having a square spacer between the firewall and the round portion of the booster itself. You can see it in the middle of the picture he posted.Darren Quote Selected
