I agree with fastmike, the shocks aren't my problem right now as I have no complaints about the stock ones so far. After alignment and bit of mucking about with tire pressures, this car's in pretty good shape. As we learn the car more, perhaps then we'll look at shocks.

Here's a few pics with the 285 Hoosiers mounted on stock legal wheels. In fact the Sly has 295/30R18 Hoosiers on it.

Man, that looks SO strange. They look like Goodyear cantilevered slicks!!

Actually that's not the case, there are some inherent weaknesses with the S2000's suspension design that are not easy to overcome. If you look at what Honda has done over the course of production, they continually softened the suspension - however there are some very nasty camber curves, especially in the rear suspension that cannot be simply dialed out. This is not to disuade you from getting an S2000, i loved the one I had. But be warned, they are tough to drive, and the early ones especially are very edgy.

Fastmike, I've seen the dyno charts comparing the base NA shocks to the DA konis, and they are infact better (faster, especially at low-speed). However what I've not seen is a comparo between the ZOK/GXP shocks and the Koni DAs. I'm going to talk to my contacts to find out if there is any valid data available.

The main reason I'm interested in the DAs is for the tunability factor. Even if they are only slightly better, I think having the ability to tune the shocks to my and my co-driver's style is very beneificial.

We are going to do our initial driving on 285 Hooisers.

Miles what sort of pressures are you running with?

I'm not sure what they ran at nationals but on the 1 event I drove on them we were running 27-29psi.

That's certainly what I've been finding.

what aspect ratio are the 2.85's. Were you serious about both being used on 8" wheels and no drastic offset. Currently my oem 2.45's are close to hitting the frame/wheelwell on a hard turn, how is the 2.95 going to fit without an offset? What wheels are on the depicted car. Sorry about all the questions, but, I am getting ready to buy wheels/tires.

One last question for all - is anyone aware of a 3.45-3.50 gear set for the rear?

According to the rules, you are allowed a +/- 1/4" offset variance from stock .

If it matters to for you, SCCA rules do not allow non-stock ratios in stock class. As for the tires, I think the 285 Hoosiers are 30 or 35 series, they DO fit on the 8" rims, and they don't hit anything. Also, the overall diameter is almost exactly the same as the 245x45/18's that come on the car.

Let's discuss this further, the 2.85 seems like the right tire, but, the recommended minimum wheel is 9.5" (I know they DO fit) that means the tire will have a crown and that is not good. Would it be better to run the 2.45 tire which will have the flatter contact patch on the stock wheel. The Kumho 2.85 is a 30 profile and is actually a .2" smaller diameter than the 2.45 x 35 Kumho.

The Hoosier are 285/30 and they are 24.9 inches in diameter

OEM tires are 245/45 and are 26.6 inches in diameter

That's a big difference. We get no help in gearing from them, and as others have said the trade off with squeezing them on a 8" rim might not lead to a better result.

Fastmike, yeah the Koni DAs are based off of Dasto's base model, which is why I'm very hesitant about them. While I don't have much National Level experience, my co-driver does, and we've talked alot about the shock situation.

If I were to go the rout of revalving the Bilstiens, how, exactly would that be accomplished? And what sort of cost is involved to revalve Bilsteins?

Also, as for the tires, I tend to be in the camp that if you can fit the tire on the wheel, wider is better (for autoX, i wouldn't recommend this for street or road race tires).

I'm still waiting for the magnaflow exhaust to be released.

The Hoosiers have a fairly soft sidewall construction compared to everything else, therefore, they WILL mount up on the 8" rims. Crowning doesn't seem to be an issue. As a matter of fact, some will say that the minor crowning actually HELPS spread the heat build up, which CAN be a problem on Hoosiers. The Kumhos won't - too stiff. People are already mounting up "oversized" A06's successfully, but it seems that the jury is still very much still out. V710 245's, A06 245's and 285's are all doing well. Right now I have two sets of lightly used 245 A06's. Once I have killed them there should be a consensus on what tires are doing what, and if there is still no great advantage of A06's over V710's I will go with the Kumhos as they have a much longer tread life. If a couple tenths become an issue, than my driver will have improved quite a bit!!!!!
