Default Ultimate 370Z Nismo BSP build?

I'm headed down slippery slope to BSP build on my 2010 370Z Nismo.

Here are my initial plans

OS Giken LSD
Intakes
High Flow Cats
Lightweight 18x10.5 wheels
lightweight 2 pc rotors
Lightweight flywheel
Lightweight battery
JRZ or Moton adjustable dampers
Monoballs to replace bushings

What else should I think about? ...Other than total destruction from 450 HP E85 EVOs.

What spring rates are you going to use? Also going to need a bigger front sway. I'd go wider than 10.5". Get a single exhaust made.....probably save 30-40 pounds. Test-pipes will save you another ~15 and add 3-5whp. Then have it tuned with Uprev (available?).

I don't know what rates are used for AX? I have zero experience with these cars.

I'm not convinced that I need more bar than what Nismo offers yet? The car already has fairly stout front and rear bars. I tend to favor cars that have a little roll and are a little softer than typical track setups. I still want to drive the car on the street.

There really isn't a set spring rate....just have to find what you like. Can be anywhere from ~600-1200lb on the front depending on what you like (some go higher and run no front bar). Similar for the rear. The nismo is pretty heavy...even in BSP trim though. I would find something towards the lower end of that range...get a big (adjustable) front bar....since you prefer a bit of roll. just my .02.

The last I checked monoballs were not legal in Street Prepared. Non-metallic bushing material only.

What else should I think about? ...Other than total destruction from 450 HP E85 EVOs.
Weight and rear traction.

Full engine rebuilt with parts swap blueprinting.
.472" overbore.
Maximum head shave (.010").
Port matching.
Long tube headers with a merge collector and 3" single exhaust.
No cats.
Aftermarket computer.
315s on the front and back on 12" rims.
Cut the fenders and flare.
Remove the radio, AC, and all related components including the wiring.
Replace driver and passenger seats and seat mounts with race parts.
5 1/4" multi-disc clutch and almost no flywheel.
Delrin/Hydlar chassis mounts and bushings (where possible).
13 gallon fuel cell.

The top guys in SP do all of the above (and more). There will also be a monster Supra in BSP this year.

What kind of autocross talent will be behind the wheel? I've always felt that a well-built and driven BSP Supra could get it done against the Evos.

dont forget to order both VVEL motors and position sensors... not reusable adds another $1000 to the build
As soon as you unbolt the motor it is no longer calibrated... and you will need consult III to set and relearn position

Or just bolt HR heads on it and get some C10 cams run a HALTEC and bam you have the NISSAN can-am engine for the 370z

Swapping heads and/or cams are not BSP class compliant. The engine or transmission would have to be swapped as a whole.
