S2000 CR Club Racer Edition CR stands for "club racer," conjuring up the good old days when guys drove their sports cars to the track, raced them, and then, if the racing gods were smiling, drove them home again

I drove the prototype back in 07 when it was in a V35 G chassis instead... its scary that the new M kept the drivetrain almost identical to the prototype. I like it.

I have had great results using the NGK bkr8eix plugs. They say they are pre-gapped but you will have to adjust them a bit.
Details please! I was advised to keep the OEM plugs unless I have some serious power adders, even for heavy duty track use. My wear on the plugs would seem to agree; I check them every oil change to be safe.

I'm running advanced timing w/ flashpro... on a side note, Shawn Chutch fine tunes to tenths of a degree... my car's been on the dyno for a good 5-6 hours and probably 120 pulls... all for a whopping 20 horses

Yeah, the RWD drivetrain is nice. I had the new-model FX35 RWD, then decided to upgrade to the FX50 which is AWD, and I miss the RWD alot. Now I wish I had the M35H lol. But after 3 straight new Infins, I feel like a change.

Just gap to stock using the plugs mentioned above. They might add another 1 hp but also widen the tolerance for detonation slightly.
