dumb question:
When should I replace the rotors? I have no cracking, just some wear. This is a stark contrast to the way rotors "gave up the ghost" previously.

Those look very similar to the Wilwood UL32, which are $5 more.
There have been some comments about the practical differences between UL, HD and GT rotors, even in this thread I believe.
The UL are a lot cheaper, but can the Dynapro pads work with a "far side id" of 8.34 (1.705" vs 1.94" radius and of course the difference in heat sink mass).
The pad #7816 seems to have a 1.66" radius (ruler on the monitor) so the skinnier rotors might work after all?

The Wilwood selection in 11.75x0.81" with 8x7" bolt pattern
GT36 11.75x.81” far side id 7.87”
HD36 11.75x.81” far side id 7.87”
SRP 11.75x.81” far side id 8.34”
UL32 11.75x.81” far side id 8.34”
ULHP32 11.75x.81” far side id 8.34”

No revolutionary news... But I'm bored at work and might have use for the knowledge someday.

I'm sure Wilwood has a minimum thickness spec, I'll see if I can find it on Monday. I typically put a set of rotors on for every 2-3 sets of pads.

Do you just ask them to put the weights as far in (towards the center of the car) as possible?

So I see an option on the website for the 6 piston calipers. Talk to us about what that does for us, other than provide more upgrade monies for Theseus, and allowing us to say we have better brakes than Hustler.

Do they run the same or different pads as the 4 piston calipers?
Do they have the same or different clearance requirements than the 4 piston calipers?

Current 11.75" 4 piston caliper owners enjoy relaxed-sphincter braking confidence. Will these 6 piston caliper kits in fact move us beyond that, into a zone of such braking confidence that our sphincters are so relaxed, we must needs wear Depends during track events?

The 6-pots are really just for bling. The pads last slightly longer (maybe 10% at most) and the caliper is stiffer so the pedal feel is a little better, but I think Rover and Theseus have the best Miata brakes in the world, and the small pad life increase doesn't justify the extreme cost of the pads or the calipers. I've tried the 6-pots and I still have the calipers, but we use and recommend the 4-pot calipers on both cars.

6 pot wilwoods def more of a bling upgrade. Need to post up a shot of mine.

Question 1: Does the 11.75" kit clear the stock NB 16" alloys? Specifically the "twisted spoke" ones, as they are the ones I have. These wheels are my dd & winter wheels.

If this is an unknown question, I will post my results. I assume spoke and not bell clearance would be the issue, but I've been bitten in the ass before by assuming.

Question2 : are the 8mm spacers only required with the older +40 6UL's? I will be running +36 8" Gen1's for wets and +36 9" Gen3's for dry. If I might need an 8mm spacer, I'd like to go ahead and order it in advance so that I'm not stuck waiting on a spacer.

Question3: When ordering spacers from say Wheel Adapters, Wheel Spacers, Hub Rings, and much more! | Motorsport Tech should I specify the extra wheel centric machined lip?

Question4: With 5mm or 8mm spacers are the stock wheel studs still long enough? There was discussion of this earlier in the post but I'd like further verification. For track use purposes.

Observation: Sav maybe you should make a "TSE BBK wheel fitment" thread for all this info to accumulate into instead of us having to use the Group Buy thread?
