Talked to Todd again and I have a list of some information He is looking for. We're going to start with pricing a 13 inch diameter, 1.1 inch thick rotor, using the 4 pot Wilwood FSL Caliper. an INITIAL guess would be for the rotors, pads, lines, calipers, and adapters we would be in the 1300-1400 range for the front. This could easily be upgraded to 6 pot calipers, or thicker rotors at an additional cost obviously. We're thinking we should have a fair amount of flexibility once we get all the dimensions set up.


Here is the information Todd needs, while you guys have your brakes all apart.


Front rotor dimensions- OD and width.
Front rotor hub bore
Front rotor stud circle and size
Front caliper piston diameter(s)
Stock hat offset (or a rotor to work from which I'll inquire about today)

Master cylinder bore

Rear rotor OD and width
Rear piston diameter

Another option would be that if there is anyone around the Phoenix area that is interested, and could help out by dropping their car off at Todd's shop, he could get the ball rolling on this a bit faster. The rear kit all depends on how the e-brake is set up, and if how it is similar to the WRX/DSM.

Matt,

The Nissan calipers are aluminum and the Subaru calipers are cast iron?

If NISSAN is machined off, those lighter calipers might go unnoticed in stock auto-x.

What did Nissan use for rear calipers and how do those compare?

Not sure if I pointed out...Subaru calipers about 6.5kg each...Nissan calipers about 2.5kg. 14lbs to 5.5lbs each

Need for speed(forgot your real name sorry)...yeah Nissan are alloy and subaru iron...heaps of weight difference, and for me, worth exploring to save the 8kg.

If you read NASIOC (and I'm the first to not just believe everything I read on the net), the Nissan can't be ground off...not sure why not.

The point made was that NISSAN can't be 'scrapped' off.
Can easily be machined off.

Since the calipers are already prone to flexing, I would be cautious in any attempt to remove material from them. that is the only issue with the Z-calipers. I have been doing a alot of reading on these calipers as well as the Subaru ones... Good choice but I recomend getting a bigger disc than the stock 300zxturbo... My brother had them on his z32 and they were not really all that good. I would say the suby 2 pots on the front of the SVX performed better along the lines of brake fade... Big rotors with the z32 4pots and you got a decent cost efficient, lightweight, BBk

Tom...yep good suggestion for you guys...for me, a 15" wheel does most of the dictating.

To be honest though, most rally cars, with under 300mm diameter disc, rarely, if ever, have fade. I'd put fade more down to pad quality than rotor size.

Hi Tom,

I've read about the Nissan calipers also. The Nissan caliper has no ridges or ribs associated with the lettering to strengthen or prevent flex. I doubt that removing the letters would have any effect on flex. If I remember, the guy that installed the Nissan fronts used Celica All Trac rotors, not turbo zx.

Have you found any replacement factory production rotors, larger than 13", that could be adapted for use with 18 or 19" wheels?

What size are the Tribeca front and rear rotors?

Soo I have some good news.

I talked to Todd again today and things look promising at making the wilwood kit.

The one thing we really need to know is the radius of the mounting tab holes to the center of the hub. If this is different, a custom bracket would need to be made (either for the STi brembos, or the wilwood kit) If anyone has a drawing, or could take measurements of this value I would appreciate it.

For prices, IF the bolt holes are the same distance away from the hub, we would be looking at ~$1400 for a 6 pot setup with a 1.25 inch thick 13 inch rotor. (these would be the BSL-6N calipers) you could also "downgrade" to the FSL-4 (forged super light 4 pot calipers) This is a rough estimate, and this is assuming that clearances are how we expect. If there is anyone in pheonix who has some extra time, Todd would love to be able to take some measurements on the car just to ensure there are not clearance issues.

The rears also look promising as the E-brake setup is the same as the WRX. Again a rough estimate, however doing a rear 11 inch setup with 4 pot rear calipers could be done for about 800$


People. this is $2200 total for all 4!! this would include adapters, lines, rotors, pads, calipers etc. Not only that but it would open a BUNCH of other pad and rotor choices, as the SVX has a rather limited number of pad manufacturers. I can't believe how cheap this is turning out for the amount of stopping power. This is about the same cost as fitting STi brakes, and would offere significantly better performance, as well as being custom adapted to our M/C size.


Again if anyone could take those measurements on the SVX, or if anyone in the pheonix area would like to help out... we should be able to get this kit together pretty quickly.

Sti fronts can be had for cheap if you look in the right place. A full front can be had for less than $800 and I can actually get fronts and rears with rotors that may or may not fit for $800 plus shipping... So another $600 for just fronts is not making it for me. Plus, if the fronts are merely a direct bolt up which is what I am leanin toward... ANY STi BBK will work, which would make no sense for him to make a custom kit... Let me see what I can find with my measurements... Then we can work from there

I'm with you Tom...WRX 4 pots ARE bolt on, STi' Brembo's PROBABLY bolt on...they've got to be the path of least resistance.

Tom, are you saying WRX 4 pots (not Brembos) are $600USD a pair in the US?

Did I mention elsewhere that the WRX 2 piston rears DO NOT bolt on...

Tribeca is a good question...are they 5x100PCD or 5x114.3? Given they are virtually a Legacy platform (I think aren't they?) they would quite likely be 5x100.

Ok... here is the rundown...

The wrx4 pots here are red ones from the 06... They get pricey

The Brembo can usually be had for around $700-800 for the fronts

Fortunately I made good with the guy who sold me my 6mt in Canada and he owes me a favor. I will be getting a set of Front and Rear brembo calipers and rotors for $800 Now they are the 5x100 bolt pattern so I will drill out the ones he sends me for a test fitment... IF they fit well I will go and buy new rotors with the 5x114.3 bolt pattern along with new pads... The rears are not a huge concern as I can adapt the rears to work simply enough by using the dust sheilds from an STi redrilled to our hub pattern. Our parking brake assembly is similar to theirs from what I have come to understand. SO in short, I will be picking up a set of front and rears in the near future and I will be making them work. If the front rotors are not the correct dimension I will find ones from that chart that will work or I will have custom ones made... I am under the impression that they will and I am waiting to get SVX measurements back from Gest24 so I can compare specs from the SVX and from the Sti... So I think we may have a winner here.

I am also concerned about the mastercylinder's ability with the new calipers so I can always grab an Sti master and be able to use it like Bob's your uncle I also want to get my hands on an Sti Brake booster as While they have the same dimensions I have a feeling they work much better than the SVX one. I installed one into Shotgunslade's car and his brakes feel amazing. Thats all I know right now. I will be pulling hubs of a parts SVX tomorrow so I can mock the calipers and rotors right here in my apartment. Once I know what will/will not work. I can tell everyone more
