wilwood + corrado rotor idea

[p0cket penguins]

Hey guys,

So I was searching for a ghetto bbk idea and i came up with this (plan to run these with my kosie k1's 15x7 rim)

280x22mm 4x100 vw corrado rotor (needs to be milled 1mm in the hub)

Hawk blue track pads -- http://store.summitracing.com/partde...5&autoview=sku

Wilwood forged 1.75inch piston to fit a 1 inch rotor--- http://store.summitracing.com/partde...5&autoview=sku

Might need some brake pad shims to go with it though

the benefits of running this set up is that you can use stock rotors so every time you need a brake change you don't get pwned. Of course you would have to build and adapter for it but it would be worth it at the end.

what do you guys think?

[Mossman]

I don't have the same exact wilwoods but that's basically what I have in my turbo project car that I haven't touched in a year.



corrado rotors still look dinky in 17's. On these the hub was turned down as you suggested so stock rotors can be used.

Gimme a ring sunday if you want to come grab an upright for mock up.

yeah im running them on 15in kosie k1's .. best cost to tire ratio and tire to weight

what bracket design did you make sam?

You'll be better off running the smaller piston calipers as your stock caliper pistons are only 48mm (1.89") and you need to calculate surface area of both pistons on one side to get the correct piston size. In our case it would be the 1.38" piston calipers, 120-6806. The larger piston calipers would increase your pedal travel a bit as well as creating more clamping force per given pedal pressure.

I sell the 6806's by the dozens in various kit I make, so if you want a better deal than Summit on the calipers or the Hawk pads, let me know.

1.38" pistons to 1.75" = 160% more pedal travel/hydraulic force. Will also result into major bias imbalance.

Two 1.38" pistons has about the same hydraulic force as one 48mm. In fact it is only 6% more (which won't be noticed by 99% of drivers). Coupled with slightly bigger rotors, I suggest to remove the fixed pressure limiting valve on the firewall to overcome that slight imbalance.

Hey this is a great idea!!

You should make up some brakets and start a group buy, i'm interested in this buget bbk route

So all i need is your bracket(in inches) from your link, the 1.38 piston 1inch thick rotor wilwood caliper(1206805), and a corrado rotor thats shaved in the inside? Do i need to change the MC at first or do anythign else?

that's pretty much all. I am using a 25mm master cylinder and a bias valve but i like lee's idea of just removing the restrictor. The stock mc will be fine.

so i had a great idea....

e30 rotor dimensions 260mm x 22mm, center bore 79mm, hat height 35mm

John cooper works mini cooper s rotor 294mm x 22mm, center bore 56.1mm, hat height 44mm

so add this with wilwoods... it sounds like a winning combo... what do you guys think

[Borat]

hat height is getting a bit high, will probably touch the tie-rod mount, even the corrado rotor gets very close at 39.5mm, would most likely need a spacer ~5mm under the rotor

id you want a bit bigger than the corrado theres an audi 3 rotor, 288x25 (extra thickness is main thing) and 35mm high. 5x100 so three holes need to be drilled and the centerbore englarged

[Massive Lee]

The bigger 298mm rotor kills the purpose of using a smaller 280mm that fits more wheels.

If I get 10 pre-paid orders, I will supply an aluminum radial mount to fit Wilwood's Powerlite caliper (and a Corrado disc) that costs only $140 each.



I won't machine hubs or rotors. I will only supply the pair of anodized aluminum mounts at a cost of $200 including bolts. And you source the calipers from any supplier.

well if massives 300mm will fit under kosies the 294mm should fit right under there too.... im thinking get some 5mm aluminum wheel spacers and machine them to fit between the rotor and the hub.... that would put the rotor at 39mm and space it from the tie rod.... plus its like i get some free 5mm spacing up front.

WOW--- I hope this is still around during Tax Season
