Reading comprehension isn't your strong point is it, son?

I have to disagree on that last statement ( I think ). Disk brakes are both better and easier to work on than any drums I've ever maintained, hands down.

BTW, I think you thumb is cramping or something. Try a real keyboard next time.

Seriously maybe the cables and brackets would be doable but normally I use new parts for my brakes.

Socal junkyards have a 15-day warranty so install it quickly, take it for a run and do lots of braking. besides, it will only take a few minutes to figure out if they are bad. On a much serious note, I havent seen any issues with boneyard calipers.

This kit sounds solid enough to me, but it would sound a lot better if the price was right!

I don't even like to take my rear wheels off in fear of my drums.

Siraniko 03-25-10 08:24 AM

billys prices are reasonable. it just seems a lot as you need other parts to convert. Otherwise, grow some balls and deal with your fear of drum brakes LOLLLLLLLLLLLLLLL

Holy cow just buy the GSL axle, if you can find one grannys speed shop sells a ford 8.8 inch rear end built just for rx7 it bolts right in and it has lsd with disc you can get it in 4 bolt 4x110 or the 5 lug 5x114.5(i think thats right its GSLSE patter)

check it out if you plan on adding power this it the way to go.

I think you missed the points here.

1. Keep the 4 x 110 rear axles and most of the rear end intact.

2 Keep the costs down yet upgrade to disk brakes.

Billy is supplying the missing links needed to do that at a very reasonable price
with the typical ReSpeed engineering and quality behind it.

Sure I can spend 2 grand with grannys but I could get another car for that
kind of dough.

Man_in_black49464 10-25-10 11:10 AM

you should should know better if you own a RX7 you will pay to play and upgrades dost money if your looking for cheap you picked the wrong car.

I would love to see parts as cheap and easy to get a honda but it not going to happen,

t_g_farrell 10-25-10 12:40 PM

Sure if your building a dyno queen, you have to drop $$$ to get to whatever level
your going for.

I'm all for keeping my car looking and feeling fairly stock but with some
modernizations as long as they don't ruin the stock look and feel. I'm not out
to rice it up or make it something its not. Its not a 1/4 mile eater, its not an all
out race car, its a classic jap sports car that I've owned for 27 years and I like
to drive it on a daily basis. I think your missing the whole point to this thread.

I already contacted billy and grant. I am doint the respeed big brake front with the turbo 2 parts, with the crossmember upgrade (and better steering:) ), Also getting the rear end from grannies to accommodate the same on the rear. Got my brakes here and in the process of rebuilding them. I done this on other cars and I can tell you it is worth it.

Oh, I been meaning to ask about brake lines, I think I will redo the entire car since I am upgrading MC as well.

Hey did you end up getting the Level 2 kit from Grannies for the rear? Are you using that with a rotary engine? Have any pictures of your brake setup if you've gotten that far? Thanks man.

dream36realms 05-16-11 10:05 AM

I got the level 4 kit and it is not in yet. I am not in the usa yet but will be soon. and no i am using a ls1

Then again, would that be all that'd be needed?


rafaelnun1 06-07-16 02:17 PM

yes yes bigger brakes. Finding rear axles are a pain in socal.

I would be happy to share the CAD if you want to have some made, I even have a shop I work with that will laser cut them for a $60 minimum which would probably get you 2 sets. You would either have to machine the aluminum spacer behind the rotors yourself or find someone to do it, I have a dimensioned drawing for it.

What years does this brake adapter fit to? And what calipers can be fitted to this adapter? Preferably if the same rotors and calipers as the front as I’m about to purchase new calipers and rotors and just buying 4 of everything would help.

MM54 12-15-17 10:01 PM

Wow, this is still a thing? I had assumed because of the time since last updated it was an abandoned project. I'd be curious as well what calipers/rotors/etc that this uses (proportioning valve?), I may be interested in a set.

1BADRX7 10-31-20 06:41 AM

I know it's old but does anyone have a kit for sale?
