Wanted to share my install and hopefully this will help someone in the future. This was installed on a 2007 Z06, but I had base C6 calipers & rotors already for my drag setup, along with LG Drag Spindles. Huge thanks to Fartpipe and Stanger383 for their assistance with this.

Here are the parts and part #s I used:

Strange Pro Series II GM Front Brake Kit: B4178WC2
http://www.strangeengineering.net/dr...-pc-rotor.html
Wilwood Flexline Kit: 220-9101
http://www.wilwood.com/LineKits/Line...temno=220-9101
Milled down 1 1/4" i.d. washer: Sourced locally

There was quite a bit of cutting on the spindles and the washer was needed on the axle to clear the wheel speed sensor wires. The parking brake also had to be removed.

Rotor & Parking Brake weight savings: 9.12lbs
Caliper and pads weight savings: 1.71lbs
Total: 10.83lbs

On to the pics....

Stock caliper mounting points cut off and recession cut for Strange caliper bracket.




A washer/spacer is needed because the speed sensor wire is pinched by the axle



Here is the machined 1 1/4" i.d. washer I had cut down on a lathe

Very cool. Thanks for sharing.

For clarification, if you don't run speed sensors, there's no need for the washer, correct?

I'm thinking about making the swap to Strange rear brakes on my car.

blkscls1z

It would be really close, but I think it would work without the washer.

You planeed on doing away with abs tcs and active handling?

C5 Pete

Yeh. My car is a track only car. No abs/ah/TC. Manual brakes. Manual steering. No airbags.

Doing this swap soon. Gathering the parts now. Do you have a link on the Wilwood flex line kit? For some reason I can not find that number. I would imagine the same is required for the front brakes as well. What thickness is the machined spacer 1 1/4"?

blkscls1z

Typo on brake line part number. I edited the original post and added the link.

I didn't have to use the 45 deg. caliper fitting that comes with the line kit. The straight fitting that comes on the Strange Caliper worked fine.

I didn't measure the thickness of the washer, but I can. I do know another person that has done this and they used a 1/2" washer/spacer they fabricated themselves. Mine wasn't that thick, but there is very slight rubbing of the wheel speed sensor wire sheath on the passenger side. Driver's side is fine though.

Do you know if the lines are the same for the front or not. I found the number:
Wilwood Braided Stainless Steel part# 220-8176
I saw you asked in the thread I posted in awhile back to kromberg but he did not reply.

blkscls1z

The part # you listed is C5 front specific. Part # 220-9100 is C6 front specific. Only difference in the C6 kits is the line length.

Not sure if there is a difference in the chassis fittings from the C5-C6, but I do like the chassis fitting already integrated into the lines of the C5 kits though. .

I ended up ordering the 220-9100 kit for c6 front. I'm doing my front brakes first and rear next. Thanks for the response.
Did you every happen to note the thickness of your 1 1/4" spacer that was machined? On a different note how does it drive with the new brakes? Any issues or complaints?

C5 and C6 chassis fittings are NOT the same. One is M10 bubble while the other is M10 IF.

Cross fitting these can lead to damaged hardline and may require a nice cut and flare job to correct it...no fun.



FWIW, I stock all four options (F/R, 5/6) hose kits with dedicated swedged ends and bent tube, swivel AN caliper ends for all Wilwood kits. We don't use the factory supplied line kits as I personally hate all those messy fittings....

blkscls1z

Drives fine so far with just the rears. Can't really tell much difference in my opinion. I'm leaning towards doing fronts also. Have heard that the stock front calipers will just lock up the skinnies anyway. There is a lot more weight to lose in the front than the rears.



I had the washer machined down to match inner lip of the axle.

blkscls1z

Good info, thanks for clarifying.

Have pics of your line kits and prices? Didn't see them listed on your website.

Great stuff. Exactly what I was looking for. I will be installing my fronts next week. If there is anything hurdles I will post them. should be fairly straight forward. Eventually I will put them all the way around.

I don't list hose kits on the web page as they are included in nearly all brake kit sales anyhow. The C series hoses can be had in any configuration (F/R 5/6) for $55 plus $8 USPS. That includes the hoses, npt adapters for Wilwood calipers and clips. *These are not for oe calipers.





TCE hose kits use 45 and 90 degree hoses end rather than npt adapters as found in the Wilwood factory kits. The reason is that it makes them easy to adjust or 'index' where you want them without the potential for damages done to the alum caliper body by way of the pipe thread. Lessening the chance of breaking off that 90 degree adapter or having it too lose and leaking.

Thanks for asking, no hijack intended.

blkscls1z

Thanks for the info. If I do the fronts I'll get lines from you. I like yours over the wilwood line kits and they are priced comparably.

I've got dual Strange calipers on each rear corner. They work very well. I found it necessary to use a brake proportioning valve to dial in the system with front skinnies and stock calipers.

whitelt3

What length bolts did you use to replace the OEM hub to spindle bolts? They appear to need to be approximately 12mm longer. I think the bolts are M12x1.75.

How much did the rear brakes space out the wheel over the base brake?

blkscls1z

I didn't measure it, but it wasn't enough to notice a difference. I'm running 15x10 Weld RTS rears.
