I weighed my Dynalites, and fresh out of the box they were 1.5 kg.

So I'm most likely going to pick these brackets up within the next few weeks.

After reading the thread, there are a few options for balancing the whole system out. What, in your guys opinion is the easiest/bolt on way to balance everything out? 1.8L rears + proportion valve? MSM rear? What has been the easiest set up to make work without fiddling and making a million adjustments?

And just to clarify again, the calipers we need are the .81 thickness? 120-6806?

prop valve

prop + 1.6?

prop + 1.8?

prop + MSM?

prop + flyin miata bracket + 1.8?

I use a prop valve and stock 1.8 rear brakes on my car. The calipers are 120-6806s.

Sounds good!

Should I go with the Tilton or Willwood prop valve, is there any preference between them?

I used the Wilwood valve due to ease of install, I've never played with the Tilton valve so I wouldn't have any setup advice for you. I thought it might be nice for playing with the bias on-track, but for me the Wilwood valve seems to be a lot more set-and-forget than I expected it to be.

That's what I figured. Looking at pictures of both, the Wilwood seems simpler and easier to use.

Just for kicks... here's a pic of stock 1.6L brakes after 2 session of our local track. Off a friend's turbo miata...

I wrote a spreadsheet:

You will get MUCH better bias by increasing the rear brake torque first, THEN add an adjustable prop valve if you feel it can still be improved. The main advantage is that bias will be closer to correct at a single setting of the adj prop valve, over different surfaces.

The use of the 94~97 1.8 rear rotors with the larger-pistoned 01+ "factory big brakes" rear calipers is a damn near perfect match to an 11" front kit with 2 x 1.38" pistons.

They are $80+ per side at Rockauto. Cheaper and lighter than going to a Goodwin rear BBK or the factory rear big brake rotors + adapters.

The calipers are that much? ($80)?

Are they a bolt on affair without adapters and match the 94-97 rotor?

Who knew you could get a full on big brake kit for so little! I'm starting to like this more and more.

Even after an alignment and tire change, my Wilwood proportioning valve was still at or close to optimum (front lock just before the rears)


Answers within

2003 (big pistons) rear calipers would bolt onto a 94~00 car using the 94~00 pads and rotors.

Any benefits to them when using an adjustable proportioning valve? hmmm

Pls re-read my post above, and the thread I linked to.

Nick/crashnscar, I pm'd you :)

Oscar, Nick is in Canada this week for spring break. If you need a more immediate reply, shoot me a PM or email: info -at- trackspeed engineering -dot- com.

Sweet, now get me my invoice ;)

this just in...it looks like either my spacers collapsed or my spindle bent, not the brake kit. Yeah!!!!!!!for trackspeed.

Wut spacers? Keep us posted, I'm sure you will.

I just installed these....... WOW, never going back to a traditional caliper. After figuring out how easy it is to install pads, I now know why everyone does street pads and track pads with these calipers.

Silly question but got to ask will the 13x8 Rota RB's work with this kit?

tia

Not a chance, Grant. Sorry. :(

I haz dem hoez double stacked now so they clear the wheel.

how much spacer did you need to run for clearance? I'm getting worried about fitment with my 15x7 +38 K1s now

If you want multiple piston and dont give a shit what it looks like, BOOM-- junkyard FC calipers retro`d onto your existing rear assy. I dont remember how people got that working though, but you are probably smarter than me, right?

4mm

FYI, Kosei K1 in +38mm offset fit with no problems

Awesome. Glad to hear that Oscar.

What about OEM 10AE wheels?

no

IIRC the OEM 10AE wheels are 15x6, which will most likely not fit. The '01+ Sport/Special Edition wheels do fit, however - that is the only OEM wheel that we can confirm fitment on at this time.

I can go outside tomorrow and stack spacers on 99-wheels until they fit.

Can you please let me know if these will fit with 7x15 RB's.

99 wheels do not fit (including AE wheels).

Can you confirm if these will fit with 7x15 RB's please.

Sorry double post!!
