HELP! 1966 coupe front disc conversion

Looking into a complete disc conversion kit for my 66 straight 6 coupe. So far discbrakeswap.com seems the most complete and cost effective. However I have a few questions...do I need to upgrade the steering linkage if I am keeping the coupe a straight 6 and never looking to upgrade to a v8? Can I use a 4 to 5 lug adapter if I decide to keep 4 lug all around, but prefer 5 lug wheel options? Also, has anyone used discbrakeswap.com for a similar set up? if so, any suggestions? I don't want to have to convert the rear and look for an 8'' rear end, so I'm focusing on a manual front disc brake conversion and keeping the 4 lug. Any help is appreciated!!

I have the 4 lug kit from Stainless Steel Brakes for the front. Got it frim CJ Pony Parts on sale a couple years ago. I got the power booster too. Works great but a real pain to install the booster.

Nobody sells anything for the rear. I will be experimenting with adapting rears from a foreign make to my 7.25" axle. Nothing to talk about yet. I haven't found any options for the rear to keep 4 lugs.

You either need to go whole hog and get the 5 lug set up all the way, suspension and all, or you need to be ok with front disc and rear drum and 4 lugs.

If you are never going to upgrade to the V8, then my suggestion is to keep the 4 lug (there are plenty of wheels still made for that bolt pattern and offset) and put the front disc on. Use a proportioning valve and put upgraded shoes in the discs in the back. Car will stop just fine with that, booster or not.

That's what I'd do. 4 lugs, discs in front, booster, and prop valve. Done.

That's exactly what I'm planning on. Thanks for the advice. Any wheel style or vendor suggestions?

I like some stuff they have here:

http://www.performanceplustire.com/

If you take the survey when it pops up, they might email a $20 discount.

Oooh, I meant 'shoes in the drums in back'. Not discs. My bad. Sorries.

As far as wheels, I would make sure of offset, lug pattern, and max width issues. I don't remember the offset or lug pattern, but I do know a set of 15"x7" American Eagle Polished Aluminum/Black inset 5 spoke wheels coupled with 205/65R15 BFG Touring T/As did look pretty 'right' on my Muskrat. But they don't make them anymore:

Although these days I would probably have gone with 16 or maybe 17, and got the 5 lug discs all 'round instead of stickin' with the drums.

/I should totally get another coupe and do it like Muskrat with a V8 instead... No, stop, I need no moar projects...

I think I'm gonna stay 4 lug and do the front conversion. Think I'm gonna go with the graphite konig rewinds. Bolt pattern for the straight 6 is 4.5...do you by any chance know if there would be back spacing issues with 16 inch wheels all around? Also, I'd like the look of a low profile (thinner) tire and a bigger wheel (but nothing crazy big)...any tire size suggestions to go with te 16s and accomplish that look? Thanks again!!

The math isn't too hard. See how tall your current tire is then convert it to mm. Subtract the diameter of the wheel (in mm). This leaves you with the tire sidewall height times two (top and bottom combined). Divide that by 2. Now you have the height of the sidewall you need. In tire sizing, the first number (for example 215) is the width in mm. The next number is the percentage of the width that gives the sidewall height (for example 70). In this example, the sidewall would be 70% of 215 mm, or 150.5 mm. Remember to multiply by 2 and then add the wheel diameter. If this was a 16" wheel, you would add 16" plus 11.8" and have a total tire height of 27.8". Use trial and error to get a width/aspect ratio that meets your need.
Pretty easy, right?
