Z1s in 205/50/16: In Stock!! ;DI want the Z1's to get in stock!!! NOW!!! i'm starting to worry....even though it's a while out still.Looking forward to a very good GC battle in STS with nearly identical setup cars. It doesn't help that we plan and work on the cars together. :
The only major differences are going to be alignment specs (maybe) and driver. We might even have the same tires...!

the B9 bar has worked out really well for me last season, kept the camber in the front much more in check then the wimpy stock ones. from what ive read there are two ways to control roll, huge bars or SUPER stiff coil overs and as i don't have a grand to drop on those, the big sways and the prodrives work out well for me. the B9 is the bigest bar that i'm aware of for the GC chassis. it's it's all of like $50 from joel.
the LSD is STS legal. it's off rads RS. is a stock VLSD and is AWD those are perfectly legal, hell if my car was one year newer it would have one stock.

You are not allowed to Update/backdate in STS, by the rule that would put you in STX, and here is the rule for STX:
5. Only standard (as defined in Section 12.4) limited slip differentials
(LSD) are allowed on AWD vehicles. For AWD vehicles that
did not come with any type of limited slip differential (including
center differential or transfer case), a single aftermarket LSD
may be added. 2WD vehicles may use any LSD unit.
Just an FYI
There is a bar that is like 32 or 31mm hollow.. that one has been known to break control arm mounting points.

my understanding is that in an AWD car you can run a FACTORY type LSD. i.e VLSD. BUT ONLY in the rear.
that;s my understanding. i have not read anything that says that you can not update back date parts for the same trim car.

the update backdate thing is in the stock category which STS uses sans the allowances in the STS rules. basically if it aint allowed, you can't do eet.
I don't think you will have a whole lot of trouble with CMC. but if you were to run SCCA Nationals you would get hammered on that.

that's what she said.
There are some other black magic tricks to control roll, but they'll put you in super happy fun classes. Contrary to popular belief there is a middle ground between OMG stiff springs and no sway and OMG big sway and mattress springs ;D.
Yep the 32 is the harbinger of doom for the 06 alum control arms. Using the stock endlinks is not a bad idea. I'm just wondering how close the 27 is to causing fatigue since the 32 hollow isn't much stiffer.
I'm sorry my impending camber is making you all so jealous

that HAS to be with out a doubt the STUPIDEST thing that i have ever heard. in regards to the diff.
well rad, guess im not buying your LSD.

That is at a National level, at the CMC level it would be dumb to care, especially with a used VLSD which may or may not function like diff anymore. Although some people out there have been pretty strict with the rules :
Any who, if its cheap, who cares, maybe we can magically make the vin 1 year newer and then you dont have to worry ;-)
Funny story with the update/backdate, which is adopted from the stock rules as Pedro mentioned. Everyone was using update/backdate in STS at a national level, then SCCA said BTW... we forgot to 'clarify' no update/backdate.. a lot of upset people...

that's still cheating. and if i win something i don't want someone to be like well he has a LSD he's not supposed to have, i mean i already have a mystery clutch, how many exceptions to the rules can i take?

I was just speaking from a strickly material standpoint, since they're all the same shape (ish) then that point is kind of MOO. And you are right, adjustable sways either work with the concept of increase spring preload and/or the less moment arm to twist the bar idea.
When it comes down to it, the bends just give you the moment arm needed to use the torsion spring of a sway bar. The real meat and potatoes is in the middle section of the bar where the twisting forces are acting.
