S2000 STR prep resource
Another thing to warn you about - there are some strange things going on with the 06+ models and fuel starving in AS - I have no idea if the same problem will transfer over to those cars in STR trim.
If it does - you might be better off in an 04-05 car because fuel starve is essentially non-existent in my car.
I'd take the 50lbs from being able to run 8gal of gas less than have a touch more power.

I'll have my Yellows for sale very shortly if you are interested. They are the revalved AS shocks that everyone uses and are good up to quad digit spring rates. I also have a Comptech front sway bar that is no longer adjustable - welded full stiff to prevent any chance of it snapping.
Definitely clutch type diff - but thats way on down the list of priorities IMO - you'll want the OS Giken or ATS Carbon.

Good to know about the 06+ fuel starve stuff. Makes my decision that much harder though. Looks like I need to devour another few hundred pages of backlogged AS threads.
OS Giken is what I was looking at for my Z, so no surprises there. Hopefully they're less expensive in Honda-land though. Good to hear they're not top importance. The Z's diff sucks.

My car fuel starves below 5/8 indicated(which is actually somewhere between 3/8 and 1/2 actual) after long steady state left handers, it is something to consider. That said, I got it down to 2725 on the HPT Scales with that much fuel in it.
Has nothing to do with grip - we see similar levels of grip as we did on the Hoosiers - but the fact that the car rolls so much less leads me to believe that this is in relation to the location of the fuel pickup.
Everything changed though on the newer cars so who knows - I know some of the CR's and 08's starve in AS if they have less than a full tank.

Nick--thanks. I guess I'm used to thinking of taller gearing as being better, coming from a pretty torquey car. More MPH in second would mean a lot to the Z, but the early VQs don't like being spun very fast.

Be prepared to perfect heel-toe down shifting in order optimize power. It needs to become a sub-conscience activity. You will also need to be practiced at hitting third occasionally under autocross conditions with the AP2.
I have had up to 8 shifts up and down at local autocross events and 9 at the last SD Tour with an AP1.
It's all part of the fun/challenge of an S2000 IMO.
Fuel starvation is not unique to the '06+. The AP1s do it. My '05 does it, despite speculation that it had been fixed for the AP2. It takes a particular type of maneuver to trigger it: a sustained high-g left hand turn. I generally run 3/4 of a tank or more now. My car got fuel starvation at 2/3 of a tank (on the gauge) at Atwater.
The only special problem I have heard of on the '06+ cars was the throttle cut that "Rodney" was getting at the ProSolo launch. I don't know if anyone has figured out what that was or how to avoid it.

I have a freak car where mine has never starved in left hand sweepers, even on Hoosiers with 1/4th tank.
I know CKit's car has starved on a sustained left handers at (or slightly below) half a tank and his is an '02. That was with stiff springs and minimal body roll.

my question is about how much are you all budgeting to spend on str? (not counting the price of the car)

is the ATS Carbon 2 way better then the j's racing 2 way?

Budgeting? This offseason - I think I totalled up $6k the other day on top of what I've already spent (which isn't much)
Wheels/Shocks/Trailer/Tuning/Camber/Exhaust
That doesn't count the tires that the co-driver will buy. I'll probably split a set of rains with him though.
