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?

hustler 02-25-2010 03:27 PM

prop valve

falcon 02-25-2010 03:29 PM

prop + 1.6?

prop + 1.8?

prop + MSM?

prop + flyin miata bracket + 1.8?

Savington 02-25-2010 04:24 PM

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

falcon 02-25-2010 04:42 PM

Sounds good!

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

Savington 02-25-2010 07:18 PM

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.

falcon 02-25-2010 07:23 PM

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.

falcon 02-25-2010 08:37 PM

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)

125 each, but that is chump change in the world of real brakes

I assume your talking about the rear brakes? For the rear, M-tuned offers a bracket that allows 94+ non sport owners a way to run larger sport rotors.

That is why I went down this road, and I'm sure many more will also :)

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

JasonC SBB 02-26-2010 01:51 PM

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

Oscar 03-24-2010 10:18 AM

Nick/crashnscar, I pm'd you :)

Savington 03-24-2010 01:57 PM

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.

Oscar 03-25-2010 06:01 PM

Sweet, now get me my invoice ;)

hustler 03-25-2010 06:02 PM

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.

chpmnsws6 04-12-2010 12:09 PM

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.
