To @LuckyKid and anyone else running a too loud Miata, may I recommend a system from MBS? Insignificant losses vs the Springfield setup, but soooo much quieter, with a far less annoying tone. http://mandrelbendingsolutions.com/spec-miata/ I and several guys I know even run them on our street cars (I welded in a high flow cat on mine) as well as SM and Champcar builds. Loud pipes suck 😉

I still disagree with this part, but I changed mine as per the rules. Previously my brake lights (and ONLY my brake lights) were wired to always function. I considered it a reasonable safety concern and my kill switch otherwise disconnected the ignition power, and alternator/starter from the battery. So the "preferred" method as above just with the brake light circuit on the battery side. Still don't like the idea of having no lights on the tail at night if you have to shut down the rest of the car via the kill, but like I said then, that's the rules!

This is what I get... should have known better than to even attempt reason. Sigh.

You have GOT to get your head around the fact that this is NOT the SCCA rulebook... The Champcar BCCR is in no way intended to be an "if not explicitly allowed then illegal" style ruleset. I've lived in SCCA rulebooks for nearly 20 years myself, and THIS AIN'T THAT. Period.

Irrelevant photos I posted of hand ported 30 year old 4 cylinder heads. Carry on with the "original" derail

Did mine with a Foredom in my unheated mudroom... with results to match 😕 Kidding, the head came out great, I just bought scheisse replacement pistons...

Ordered $975 (25 point) 14 year old used transmission for my $300 (56 point) 20 year old engine swap into the 30 year old $50 350 point chassis... Champcar math FTW?

That's precisely how @Jer just explained it in another post... if you swap an NA6 Miata, you get to treat it as a "platform swap" and get the beefier/bigger/etc NA8 stuff "free"... just with the 50 point higher starting VPI

I know I picked my friggin' car, but they're really sticking with the theory that a 190hp v6 mr2 at 316 points isn't as fast (or faster) than a 190hp v6 240SX at 406 points? Or a 358 point Rx7 @ the same power? Wow.

Ninja edit my own post: now the "2019 Swap Calculator" is "404 File not Found" OK, so Bill ninja edited the page to be active with the 2019 calculator. Hmmm. 406 points. Are we still rounding up for laps? as in 500.001 to 510.000 is 1 lap regardless? Looks like I'll be 491 with unbalanced aero and nothing else to spend or 501 and a lap down (with nothing else to spend)

OK, so it's now January 1 2019, and @Bill Strong has published the latest revision of the 2019 BCCR. Can we now make our swap calculations without fear of weight table surprises affecting our "official" swap points? Or is it not "coming Jan 1 2019" anymore?

Depends, are you self employed? 37!

Leaves you exactly 37 calendar days to order, receive, and install them prior to tech for the first race of the year! Plenty of time!

Call it a "we didn't choose your car" benefit, but these Penskes (along with nearly every Miata "shock") are designed specifically to work with stock diameter springs and mounting hardware/top hats. It's been baked into the Spec rules pretty much forever that that's the setup, so that's what vendors who want to play in that market build to. I know the "only available through" thing makes it sound like it proprietary, but that's there because Spec guys change their hats and bumpstops like some people change their oil

different than Stock *diameters* ID and OD... spring free height/loaded height is not subject to that limit, that's the whole point, right? adjustable height while on the car = "coilover kit" = 10 points
