Willwood 2-piece rotor points


 Share

Recommended Posts

Installed a set of the Willwood calipers. 10 points. Understood.

 

If we choose to run the 2-piece rotor and Aluminum hats, what are the points for using them? We need to run them due to the stock 11" rotors are ventilated from the outside, not the inside. Brake duct cooling does not work when these rotors are used.

 

Have looked and read but have not found any reference to the point penalty.

Brake Rotor, 11 Inch vented front, 4-lug - VW Corrado G60 – Euro ...

There is no BCCR mention for over cost rotors, how many pts would they be?

 

No, only mention of rotors i see is in the 2x rule. Nothing on what happens when they are out of the 2x rule.

What car are you running?  There some other rotor options in the 11" that are stock sized.

 

Are you at 4x100?  I have an 11" 4x100 two piece combo that is pretty cheap and fits in the 2x on the miata.

LuckyKid, do you have a link/info to the rotors you use?

 

I messaged you links.  What make and model are you running?  I've been neck deep into rotors and I might have some other ideas for you.

I want in! How about a e30?

For E30s, I think the new hot setup, atleast for the Gingerman and Road America races, is to swap the front and rear brake assemblies.

Not sure how that would work but

 

Going wilwood front calipers, swapping  stock front caliper to back but need more front rotor.

sorry, It was a joke.  I don't know much about the E30 other than they are frustratingly fast and that I don't want to make them any faster ;) .  The amount of work we had to do to the Miata to keep up with them is insane.

I know some people use corrado rotors with rx7 front brakes on e30.

 

I recommend against the rx7 brake calipers. (They are awesome, but pad choice is limited and expensive and good calipers are hard to source)

 

Edit to make the point clear....  corrado  rotors physically fit as far as I understand it and are larger.

Don't worry, the inverse is equally true

Stock stock stock. 

I will drink your cool-aide once you have had a few years drinking ours... running w/auto trans.

 

I promise stock brakes will suffer more then one could ever imagine with auto + more hp. The brakes I have planned/already posses are more then described, but want points for other, still undetermined, stuff.

I think some of the 4 lug 2 piece Miata rotors from Goodwin or finding similar Wilwood parts with a Superlite caliper would be the hot setup. Would give you infinite number of pad choices and a very durable rotor. I have been saving part numbers and info on this swap. Probably going to swap to manual brake master too. Rears would be similar but maybe a dynapro caliper and thinner rotor.  Oem setup brakes well but wears quickly. Pads are not cheap and don’t last

I will cede you those points. It will be interesting to see how much the pad life suffers with the swap.

Would love to see some of that research after Daytona, I have some wilwood caliper and 4x100 rotor stuff here to compare notes/offsets if you want more data.

 

Going to be @ Daytona?

 

Did not get in early enough for Daytona  this year. I was hoping Watkins Glen was going to happen but now we are set for Nelson Ledges. I’ll go through the stuff I found and pass it along. Only piece to fabricate is a dog bone adapter for the caliper. All other items are Wilwood. I just haven’t took the plunge yet. I need a few races before I blow up the brake system

Before we replaced our brakes, I asked Jay how the points were calculated.

 

Specifically, I asked if it was 2x per part or 2x for the whole system. His answer was "You can use the total oem cost of the brake parts being up graded to base your 2x value."

 

We calculated the cost of the original parts (NA Miata):

                  Dealer    Mazdaspeed

FR caliper        $103.02    $61.80
FL caliper        $103.02    $82.73
RR caliper        $183.84   $130.29
RL caliper        $183.84   $130.29

Front Rotor       $83.35     $50.00
Front Rotor
      $83.35     $50.00

Rear Rotor        $83.35     $50.00
Rear Rotor
        $83.35     $50.00

------------------------------------
total            $907.12    $605.11

 

 

And the upgrades  were:

Front system (TSE)        $969
RR caliper                 $69
RL caliper                 $69

Rear Rotor                 $50
Rear Rotor                 $50

-------------------------------
total                    $1207

Is that in a tech-desk ticket?  Link?

 I also emailed about this very issue and got the same response. Add up the whole OEM brake parts being upgraded, multiply by 2 and if your upgraded system is below that, we're good to go.

 

Brake Parts Comparison Stock OEM     Wilwood   
Front Caliper x 2 RMB699172/3 $227.84   120-11330/29 $398.88
Rear Caliper x 2 RMB699672/3 $312.14   120-9693-SI $353.82
Front Rotor x 2 MR389724 $167.86   160-8165/6 $449.86
Rear Rotor x 2 MB587433 $167.86   160-12291/2 $269.56
Front Hat x 2 N/A     170-14683 $293.86
Rear Hat x 2 N/A     170-10690 $269.86
Total   $875.70     $2,035.84
           
  2x Rule --> $1,751.40   With hats--> $2,035.84
        Without hats--> $1,472.12

 

 

Based on this info, I'll be making my own hats and paying points for materials.

Holleeee crap.  More free stuff. 

 

Is nothing sacred anymore?

 

The proportion valve for an rx7 is 405...  the brake calipers from Mazda are like 450 EACH.

 

This is a can of worms...
