Default S2000 Rallycross build



To start off, I know I'm going to get hate for this but don't care.

Background:
I've been running SCCA rallycross for many years now, with some decent success. I placed 4th at Nationals in Stock FWD in a 00 Civic DX and 4th at Nationals in Stock AWD in a Subaru RS, I've won a few national challenge events and won my local region for the past 6 years or so, but now it's time to try something new. So I am running my S2000 in Stock RWD.

Car:
2002 AP1, Factory hardtop

Nov 2017
I won the SA class in WDCR rallycross early, so I took the S out for a test at the last event of the year.
It was just stock with some crappy all seasons and was a handful for sure, like trying to control a bucking bronco that only went sideways. It was really hard to control, I had my doubts but decided to go ahead with it for 2018 anyway.



April 2018
The 2018 season has finally started! I've made some small changes since my test last year.
- Bridgestone Blizzak LM001 snow tires 205/55-16 mounted front and rear
- Disconnected rear sway bar

Double rallycross weekend - WDCR Rallycross #1 and AHR Rallycross #1 - Disconnecting the sway bar made a HUGE difference in the controllability of the car. It's going to take some time to adjust my driving style to RWD but the car felt leaps and bounds better. It was very controllable, turn in was still very good and had rotation on demand with the right pedal without too much of the snap oversteer that AP1s are famous for.

WDCR- only car in SR class but a good test day.
AHR - I ran in the Modified RWD class so I would have some competition with 11 entries and didn't expect to be too competitive in a stock class car but we had a great battle with the top 3 drivers and I ended up placing 2nd and only 0.5 seconds out of first. Need to work on being cleaner as I had way too many cone penalties, but I was super happy with that result.


Off come the street tires

Would a nice bucket seat and a harness help?

"Stock Car Class"

You should have done this with the CR for some extra H8.

Best use of an S2000 on this forum that I can think of. Can't wait to see how this develops!

Even I couldn't stomach that.

It might not always be a stock class car, but 99% of rally tires only come in 15" so that limits the appeal of going to a higher class for now. I am still researching if I can fit smaller brakes in the front or how to get 16" rally tires.
