Hello Everyone.
My name is Bartok. I am new to the mustang forum but have been active in other forums. Finally i have decided to write up a bit in request for some help from knowledge group of the people.
I am in the process of restoring 1980 widebody rx7. At this point the next step would be to swap an rear end from mustang. Since i have a widebody kit and my wheels are European "Compomotive" with 4.5" 5 hole pattern mustang conversion is the most desirable. Also it is commonly know for mustang rear end to perform well in rx7 swaps, as well interchangeability of the parts is flexible.
So far from my research i have narrowed up the selection to an 8.8" rear end which will require a 5 bolt axles, 3.90-4.10 spectrum of gearing and definitely disc brakes. Also outer disc to disc space should be 59" but it could be up to 3" wider. Rims are 245/50/16 with a great +/- 5.5" offset.
I would love to be able to spend 1,500.00 for parts and do simple assembly, but one of the reasons to be here is to save costs and still do it right so bare with me and my questions and please respond with a help full manner. Thanx.
1. The least expensive option so far it is for me to get fox body rear (50-250 craigslist). There are some options with gearing, or i can always change it ($ 150 bucks). but not many rears have a discs. What does it take to upgrade from drums to discs. I see kits where only caliper bracket, calipers and discs are changed. On another hand i see different kits which come with a different length axles. Do i have to get new axles or not while upgrading to discs or is it also based on the kit that i get
2. what
cars does 3.9 or larger gearing comes in stock? do any of them have discs.
3. what is the diameter of the ring on the end of the axles (one between the studs). i want to make sure the rims will snug on.
4. Or maybe anyone has and "combo trick" for the buck.
-The car will be mainly raced track and i like to go sideways. I will need quality brakes (wilwood or so)
-I know that pre newest body mustangs come ofter with discs, posi and sometimes hiht gears...but do i just leave sensors disconnected, or can i eliminate the abs wheel to cut the momantum weight?
- ive hears about 8.8 rear without c-clips (i think with 9" rear axles...how is it comparibel
as you guys/gals see i am preatey confused but i hope one is able to understand my objectives, therefore please help.
thank you, and please visit my cardomain page
