RX7 caliper and bracket Roll Call

[2002maniac]

The only reason i can think of for changing boosters is if you're doing a 24v motor swap and the intake manifold won't clear the booster. I'm not sure where your friend heard that, but it's not true.

great thank you. Should I go with pads in the back that are more "grabby" than the front because of the balance difference? I have akebono euro on my E34 with M5 brakes now and I like them. What is recommended for the E30 big brake setup? I will be mostly street driving with limited track use. thanks again.

BTW do you happen to have extra fittings that I would need to use to get the E30 brake lines to fit the rx7 calipers?

I'd go with Hawk HPS front and rear for a good street/moderate track setup.

PM sent regarding brake line adapter fittings.

Ok guys I started a wheel fitment database and hosted it on my website. Let me know if you have any additions.

you should add that 16 inch basket weaves from an E38 with 10mm don't fit. Grinding some portions is a must. Unfortunately it isn't the fluid passage or even the center of the caliper that rubs, it is more of the sides.

Yea, those wheels have notoriously bad brake clearance. Thanks for the info.

Are you guys using a proportioning valve and if so what kind of bias are you using?

I submitted that TR Motorsports 15x7 et20 would fit with a 5mm spacer,but couldn't put a picture up.

But here is the pic you can use on your site:


I also just got my spacers in to run Esm 008 16x9 et15 so I'll try to get pics in later.

*just noticed on your site you needed pics/write-up of the install? If you still need someone to do it, I'm game. My car ain't going anywhere til my m50 swap is done and being unemployed gives me lots of free time lol

Here's a pic of my setup to add to the site (Konig Lightning)

I used the e34 M5 master cylinder (25mm i think?) Pedal is stiff and feedback is awesome. Shitty pads hindered me at the track but overall i was quite happy.

[2002maniac]

Sweet. Thanks guys!

I just updated the list and added the pictures. :)

i originally had a bias valve on my black car, but ended up running it all the way open so it really wasn't doing anything. With similar pad compounds in front and back, the bias is just fine.

I have an extra set of brackets and line adapters if anybody is interested. ;)

won't the turbo car need some buggbreaks?

So I always get confused with offsets. I run a 16x8 xxr i think they are 002's with a zero offset. Will this work better with these brakes or will I need huge spacers to make work? Also do you run the stock ABS with this set up? And finally I believe the rotor size used is a 280mm with these rotors, what is the stock size rotor?

Thanks for the help.

[2002maniac]

Offset is really not as much of a factor as the internal spoke design. Wheels with concave spokes will have more caliper clearance than deep dish style wheels regardless of offset.

That said, I don't think the XXR 16x8et0 was designed with brake clearance in mind.

There's no need to mess with the ABS when running this setup. Stock rotors are 265mm
