I had a couple of email exchanges with Todd at http://www.tceperformanceproducts.com/mini/kits-16/

He indicated that he is willing to offer "the same 'kits' as the MINI (P1 and P2) and supply the hoses and centering rings for the same price structure." Since it is not an officially a kit we are ordering, he stated that "Clearly I'm not hanging my butt out in the wind to read/hear of the problems with it and how I created them...! I'd want assurances from anyone who did it, or you with an order, that what we have put together is satisfactory."

I believe it is reasonable. It saves me from having to track down the centering rings and brake lines. I think I am going to go ahead with this and I thought I would share this everyone.

What I would recommend is the P1 but with HD directional instead of GT directional rotors. It is the same rotor same cost without the slots on the face.

As far as the brake lines goes the ones wilwood sells for the Miata 11" kit work.

Also need
Longer ARP studs ---ARP-AJ3150-1LB (4) ARP 3/8-16-24 stud 3.15” long

3/8” by 3/8” spacers 4 of them. I can’t remember there might be a different spacer combo that would work better than stacking them on top of the supplied spacers like I did.

What I did can be seen here.

Todd should thank me at least.

If 'Todd' assembles this kit, but with no pads (I want Cobalts) for comparable pricing, count me in. So the P1 kit, but with HD directional rotors, Miata brake lines, and Miata hub spacers.

The proper caliper spacers and longer studs would be a bonus if he wants to include them as well, but if not no big deal. I can get them myself.

Bob,

One more questions for you. I just got a note from Todd about the centering ring stating:

"My notes on some old Miata stuff says 55mm or 2.166" but not sure of the year Wilwood tells me the ones they have are 95-05 and have a bore of 3.06 or 77.7mm"

Could you share with us what size bore we need?

Thanks,

wildo

1990-2005 Miata hub bore is 54.1mm or 2.12992126".

bbundy

That is wrong though the hat bore is slightly larger than the wheel hub bore there is another step on the hub for the hat. I don't know for sure what it is. I just took a hub and a hat to my machinist and said make me something that fits.

Might be able to figure it out by searching miata rotors at Rock Auto and looking at drawings. Possibly look up the ring that wilwood uses for the miata on there site they usually have drawings as well.

wilwood is using hub centering rings as well for theire miata kit part# 300-11653 but I cant find the specs on them. The hat hole is huge for some reason. it is interesting that they use more shim washers for the caliper brackets on a kit designed for a miata than you need with the Mini Brackets on a miata.

I have the 11" Wilwood kit sitting at my house, but unfortunately I don't have any measuring calipers. Let me see if I can borrow some and get the specs on the hub rings.

Can someone provide a list of measurements that are needed?

mx5booster

The measurement that is of the most interest to me is the inner bore diameter of the centering ring. Also the outer diameter of the ring will be nice to have. It is item #5 in the pdf doc http://www.wilwood.com/PDF/DataSheets/ds786.pdf

Thanks for helping.

bbundy

Checking the drawings for rotors on Rock Auto the ones that give the demension say "hub register" 55mm I bet that is it.

I will be changing the brakes soon on my Corrado rotor setup. I believe the centering is the same dimensions as what is needed for the Wilwood hats, no? When I have it apart I will measure it carefully with digital calipers.

bbundy

The Corrado rings weren’t the right size I made that same swap. The Corrado rotors have a really low offset as well.

Thanks to all of your help, I think I am getting ready to place an order with Todd. He will be getting back to me with a price with everything included, meaning the studs, miata lines, centering rings, spacers, HD rotors, etc.

I am thinking about going with the "Poly B" pads. Any words of wisdom on the pads, Bob or anyone else?

Thanks,

I wouldn't run any of Wilwood's pads - go with a Cobalt XR2, Hawk DTC70, or Carbotech XP12 for the track, or a hawk HP+ for the street.

^ A big +1 on that.

bbundy

The Poly B pads are definitely track worthy bit abrasive on rotors and don't feel real well until you get them up to temp. Once up to temp they have great feel and consistency on the track but dont last particularly long. They were my track pad of choice until I found better stuff, and becoming addictied to Cobalts.

The BP10 BP20 stuff is about equivalent to Hawk HP or HP+ but you would be surprised how much less heat the 11.75" directional rotors retain than any of the 11" setups. They work surprisingly well.

My favorite pads for the track are Cobalt Friction XR2. I run BP10's on the street and for autocross and put in Axxis ultimate’s in the rear. No problem at all swapping back and forth between track and street pads with the Cobalt’s and no need to bed anything in.

Here's the link to the Hub Ring pics I took. Couldn't find my camera so cell pics will have to do.

Savington, Bob, Zx-Tex, thanks for info on the pads. Cobalt XR2 it will be.

Trackwhore, thanks for the pics. It is always nice to have visual confirmation.

I just placed the order with Todd. He is getting everything for me and it will be here sometime next week. I will let everyone know how everything works out.

I just purchased a set of Dynapro radial mount calipers.

I will be adapting them to my current BBK which is the Chikara one using 10.8'' Sport Rotors.

I will be moving to stop tech rotors from the OEM ones and making this set up as small as possible as I am going to be running 13'' wheels. Stop tech rotors are also lighter and a better design than the OEM's.

Radial calipers were the only way I could achieve this since they are a bit slimmer than lug mount calipers.

I'll post up with results in a few weeks when it's done.

Overall brake diameter will be under 310mm including the caliper. The Panasport C8's I will be using have a barrel clearance of 320mm.

bbundy

I think the caliper you want for that is the PowerLite. I have done a little thinking about smaller as well.

http://www.wilwood.com/Calipers/Cali...name=Powerlite

Then I just noticed this guy which looks like it could have some advantages as well.

http://www.wilwood.com/Calipers/Cali...%20Low-Profile
Bias would be an issue because it only comes with small pistons however.

The standard Dynapro Radial Mount really wants to work on 11” rotors or bigger. I'd recommend you go with the Powerlite radial mount calipers
