I was initially planning on doing everything at once but when I called Fortune yesterday to price out a set of the aluminum bodied 510, I was advised they are still in development, likely available in early 2019. If anyone else has an idea of where I can get a set of aluminum bodied monotubes built to order for ~$3000 let me know.

Are you going to use the OS Giken 75w250 gear lube?

You should use a solid diff bushing. You won't notice anything different.

Seb change my Whiteline rear diff bushing while he did the rear diff cooler install. He said it was pretty well chewed up. He installed a Z1 diff bushing.

I don't have any opinions or ideas on gear lube. Solid bushings are strictly prohibited in the Stu ruleset too

The OS Giken lube is recommended. It's on the $$ at $70.00 a liter. And you will need about 2.5 liters. It's the lube I use.

Didn't know that about the bushing rule.

The street version would be legal but the "race" version is a no go because of the sphericals.

Got it. I was think specifically about the fact that it replaces both arms. Any issues there?

Missed the fact that the kit was camber arm and traction arm. My interpretation of the rules is that the traction arms can't be replaced.

Quote:

14.8.H.1
On double/unequal arm (e.g., wishbone, multi-link) suspensions, only the upper arms OR lower arms may be modified or replaced, but not both. Non-integral longitudinal arms that primarily control fore/aft wheel movement (e.g., trailing arm(s) or link(s) of a multi-link suspension) may not be replaced, changed, or modified.

I read the last sentence there as forbidding the traction arm replacement. The second arm that you actually want to replace is the arm the spring bucket is integrated into. Since you can't use a truetype coilover the only options you really have are to keep the eccentric for that arm or get the SPL midlinks and replace the sphericals with poly bushed rod ends.

Not selling the car anymore since the C6Z I was going to buy didn't come through. I will be throwing some more money at parts this winter. Just picked up a 25 row oil cooler.

Looking at Z1 2pc rotors, motor mounts, and intakes.

What is everyone using for brake pads? I was reading that some people prefer the OEM pads.

I've heard some good things about the Carbotech's

I'm actually in the same dilemma, not sure what to get. The folks at Z1 are pretty helpful though, if you call and ask. Are you doing 2 piece all around? or just fronts?

Rusty · 09-27-2018, 03:09 PM

I have run both YellowStuff and Carbotech X10, X8 combo for both street and track. Both will dust. The Carbotech's will dust more the the YellowStuff.

Hows the stopping power and life length between the two?

The YellowStuff's is head and shoulders above stock. The Carbotech's are above the YellowStuff's. The YellowStuff's lasted for about 18 trackdays, and about 18,000 miles. I'm still on the Carbotech's. They will sequel at low speeds. Like coming up to a stop sigh or red light. I also run Racing Brake 2 piece rotors. They are a different grade of cast iron then the Z1's and stock.

Most likely all around. I will probably use the stock pads and see how it goes.

XP10/XP8 combo is way too much bite for autox (I ran them for most of a season). I'm running Ferrodo DS2500's on my SP car now.
