Since I have the front bumper off for the splitter install, and going with the Castrol brake fluid. I decided to up-grade the brake cooling ducts to a 3" hose from the Stillen 2" hose set-up. :tup:

Pic's of the 10ft, 3" diameter hose, 4" to 3" reducers. The factory carbon fiber RC brake ducts are designed for a 4" hose. :eek: And the flanges for the brake shield.

Pic of the difference in size between the 2" and 3" hoses.

And this is where I have to change and mod the new reducers to fit the RC brake ducts.

you summed up the subframe bushing install perfectly.

it is a gigantic pain in the *** that is worth the effort. The gain in ....predictability? for lack of a better term is worth it. There is some gear whine on deceleration (with whiteline diff bushings) but if you listen to music it's irrelevant.

I can't hear chit now. Between the exhaust and bad hearing. :rofl2:

Removed the old reducers, modded the new reducers to fit. Tomorrow, I'll use 2 part epoxy to hold the pieces together.

Good stuff. :tup:

Brake duct work. After the epoxy cures overnight. I'll install them in the bumper tomorrow

This looks like a nice upgrade Rusty. How are you attaching the Allstar Performance aluminum flange to the (OEM?) brake shield? Rivets? I've ordered a set of ducts from Kevin at FE and they are 3" OD. I'm looking to bypass the Stillen kit entirely and essentially do the same thing as you are. Also, how long were the hoses that you ordered? Could you get by with a single 10 ft piece (5' for each side) or is that too short?

Thanks,
Mick

Body glue works too.

I'm going to rivet the flange to the shield. The shield is steel and the flange is aluminum. The hose I got is 10ft long. I'm hoping that's enough to do both sides. That hose is $$

I don't think I would trust the glue to hold the flange to the brake shield because of the heat.

My guy cut the 2" flanges off the Stillen bracket and fab on a 3".

Think I might sell my Stillen kit after I finish this project up. Shields, hoses, brackets, etc.

Thanks for the feedback Rusty. I noted the same thing about the hose pricing. I found a 10 ft section of Allstar Performance hose (3" diameter, 550 degree limit) for $117 on Jegs.com I also found a 12 ft section of "high temperature silicine air duct hose" (3" diameter, 450 degree continuous, 500 degree max) for $117 on pegasusautoracing.com. I'm not sure that the 50 degree difference is meaningful, especially after the ducts are in place and the added cooling is realized.

I am curious as to whether you find that the single 10' piece of hose is long enough for both sides.

Best,
Mick

Mine has been on for quiet some time just fine. It's an option. :p

Here's my write up on the Bell Raceworks diff brace from Z1. I trashed it. :mad:

Was working on the Z today. Ran into a problem with the SLP bushings I was installing. I updated my thread on rear suspension. Starts on post #28.

:icon14:

Chit happens.

:iagree:

Getting ready to drop the sub-frame to install the SPL bushing in the sub-frame mounts. So I decided to drain the rear diff of fluid. Very pleased with what came out. No particles that I can see. The lube is dark, but not black. Pulled apart the screen filter that I installed in the line that goes from the diff to the cooler. Nothing in there either. :tup: Man.......that OS Giken lube is thick. :icon14: I'm going to leave it drain over night. Oh, there is about 2,000 miles on this lube since I installed the OS Giken diff and cooler. So it was over due for a change.

SLP? For a second thought you traded for a firehawk.

Pic's of my SPL rear sub-frame bushing install. I'm planning on doing an install thread on it. :tup:

And more pic's. :tup:

I up-dated my first post with all of my install threads. :tup:

Well. Got the front 2 SPL sub-frame bushings in. All 4 bushings are in now. :tup:

:tup:

I'm going to run the Z1 collars for a bit and then switch to the SPL bushings. Thanks for posting those pictures, I feel a bit better about the decision I made. lol

Updated my Bell Raceworks diff brace thread. :tup:

Pic's. Before and after. :tup:

That all jacked up!
