Willwood calipers?
|
Sun, 29 February 2004 10:32
|

I know I have asked this question before but i'm asking it again cause I want to.
Does anyone have the low down on Willwood calipers? I dont want to know what you've heard from a mates mate either, I want to know facts.
Are they street legal?, do they work well?, etc etc...
Anyone here using them? Thanks

Have already done all you said.
Rang many engineers all said they cant say with out seeing the calipers in question.
Spoke to Willwood USA and they say they are fine for street cars. Spoke to Willwood dealers in Australia and they say the calipers are fine for street use.
So your next suggestion?

there is no soubt that if sized correctly, they will stop the car.
the question of legality is:
are they ADR approved? (i'm pretty sure your car, unlike mine, is convered by ADR's  )
can they be engineer approved if they are not ADR approved.
they main issue is of longevity and construction. if they have no dust sheilds, they might gunk up and seize. are they designed for long term use? or short term use being cleaned after every race? are the caliper bores suitable for long term exposure to moisture containing fluid? etc etc..
basically, rign back the engineers and ask "are these calipers legal for road use and can you approve them" if they say they need to see them, ask "what will determine of they are ok or not, what are you lookng for in a street legal caliper"
or, ask them directly what calipers are ok for street use, what should you be looking for..
that help

No willwood calpier is legal for street use.
Thats what I have been told by a local wilwood supplier. Apparently they dont have dust boots or something like that so are not ADR approved.

hmm, wanna share GT?
Cool1, why would you want to use aftermarket Wilwoods when there are plenty of decent light alloy calipers around anyway? RX7, 300ZX, Skylines, etc etc??? all ADR approved

If they're anything like their rotors I certainly wouldn't be putting them on my car.
|
I agree with GT. Except for their topline calipers, they are built to a price. Speaking from experience.
Wilwood = Hyundai
Alcon = Porsche
Brembo = Ferrari
You definitley get what you pay for.
Like Stewart said, stick to road car calipers. Parts are easily available as are pads etc

light = less metal, less metal = faster to heat, faster to heat = warps, less metal = warps faster.
Brembo make a nice rotor for the Supras too.
I've heard of some people warping DBA discs at clubmeets but I think that is poor pads stuffing up the rotor on a track day.

I've noticed that my brakes get a nasty wobble when they get warm (eg rapidly decelarating from 240km/h to the speed limit) but the wobble goes away after they cool down. I'm not sure whether to blame this on the DBA rotors or the fact I'm asking more of my brakes than they were ever designed for!

Yes, I'm running Greenstuff. Haven't checked the rotors lately but I think I'll do that, good call.

Norbie are you using just the standard DBA gold rotor or the 4000 series?
Mind you I dont know the difference

The Gold rotor is the x-drilled ones and they are the same material as the std rotors, whereas the 4000 series have a much better spec material and have the 'Kangaroo Paw' venting system, and together they are better suited if you want to do some track work.
I'm using 4000 series Subie rotors on the front of mine, 1 as they were cheaper than std spec rotors (  ) and secondly (and most importantly), I will be doing some track work at Mallala which is REALLY hard on brakes.
http://www.stoptech.com/whitepapers/warped_rotors_ myth.htm is an interesting article regarding whether rotors are actually warped or not (as experienced by Norbs).
This article came from the MRT forums, a section that deals with brakes with a Senior Engineer from DBA as the moderator

That doesnt make much sense I have a new set of DBA long life slotted rotors(not x-drilled) and they have the new Kangaroo-Paw fins.

What was their DBA number ? If it was a 4000 series rotor, the part number would be DBA 4xxxSL/R rather than DBA xxxSL/R (with the L/R being for right and left).
Another differentaiting feature is the temp paint on the 4000 series rotors.
It is my understanding that std slotted rotors have the straight/curved vanes as per the catalogue
Cheers

In my case, the Std Slotted rotors were $420 each, but the 4000 series versions were $190 each (same price discrepancy for the HSV rotors as well !!!!)

I got some rotors for my Coon and I think they were about $160 for the left and right. On the boxes they came in they say someting like "utilizing the new kangaroo paw something something".

As far as I know DBA are slowly moving all their rotors over to Kangaroo Paw venting, it just takes a matter of time and doesn't include the rotors they dont make themselves (i.e. MA61 rears)

Wilwoods are pretty good actualy. What you have to look out for are these no names that are popping up.

Howdy all!
I'll be taking my Supra in to get some new front discs and front pads after the long weekend.
Does anyone have a list companys that actually make replacement discs for the MA61 Supra?? ie. I've seen Willwood, DBA and Brembo mentioned... is there anyone else that supplies them in Australia? Or more importantly in WA??
i always thought that Slotted DBA were the way to go - but if anyone wants to advise me differently, I'm interested in hearing the suggestions...
Cheers
Hope to hear from someone soon!!!

I spoke to Les Hunter here in NZ about using Wilwood calipers.
They are legal for street use here in NZ, but yes, they do not have any dust boots.
He said "... as long as the pistons are cleaned of any build-up before they are pushed back into the seal when doing pad changes they will be problem free..." also mentioned "... the pistons are very durable and I haven't seen any pitting/corrosion from being exposed, the seals are supposed to be replaced when the pads are changed and the rebuild kits are ~$15 per (4pot) caliper and the pistons are quite cheap also if you manage to damage one..."
The reason I considered the wilwoods is due to their slim design, 43mm for the outboard side of a Dynalite, compare that to a RX-7 or Skyline caliper +55mm, makes a big difference if you are trying to fit big brakes under small wheels.

Willwood calipers are the lightest on the market (2kg for a 4 POT) and are highly regarded in the sprint car industry.
Thats my 2c worth on this topic.

I'm thinking that the 900grams was for one piston
