On all these hopped up GM things I always wonder what work has been done to the braking system to help slow it down now that it has a lot more go than the stock version. Usually the answer is a shrug or a mangled Enzo Ferrari quote that translates out to "nothin'."

Exactly. You could never sell this car for its receipt value, but it's funny how things add up over a few years' time.

Forgive me but I'm not sure exactly what point you're making. Not sure how those wacky races series got brought into the discussion.

I found a rare picture of Steve-Bob-John-Jean-George-Frank-Kevin-Bill-Ian-Stuart-Sam-Richard-Tommy-Sean-Christopher-Jesus-Charles-Donald-Slartibartfast-Timothy-Nolan-Methuselah Smith from 1978.

Not saying it can't be done, it's just that it's not a real popular DIY like with an old RX7.

Actually it you want to be a true Porsche purist, no car is a real Porsche. There's some detail wrong with each one of them and it must be pointed out on the internet with sneering condescension.

I suppose the transaxle design prevents these from becoming a hugely popular SBC transplant recipient.

The 914 and 924 would be DQ'd because they're not real Porsches, and the 912 would get a DNF since it would drop-throttle oversteer into the wall while pulling onto the drag strip.

You're speaking from opinion, not experience. Do you even know that there are two distinct generations of Z4? It seems that you don't.

Love the car, but everything has a usable lifespan. How much longer (if it hasn't happened already) before the unibody starts deforming where important moving stuff attaches and begins popping spot welds just because that's a hell of a lot of use, daily or not. Very reluctant...

I've owned both, the Z3 M for nine years, and the Z4 M for six. You sound like someone who has owned neither and sound more like a kid who is raging over which Pokemon is best. Seek out a real in-the-flesh car and drive it in anger. See if you still feel the same way.

You're using the figures for the bigger, heavier E89 (2nd gen Z4 with the folding hard top), not the E85. I would agree that the E89 is more of a GT compaired with the driving-focused E85 or E86.

The CS and CSL are unicorns (in the USA anyway), so they are a little outside the comparisons. As previously noted, the E85 -6 M cars use the CSL steering and braking systems, so the only thing missing is that lovely CSL carbon fiber intake. And the E46 weight.

Drive them back to back in comparison and your loins will realign.

E85 Z4 M should be ahead of the E46 and and E36/7 Z3 M. It's the last, best of the S54-equipped M cars. So few were made that not that many people have gotten to experience them. They are wonderful.

Get one of these. Then it doesn't matter, except for possibly making those around you suddenly a lot more courteous to you.

Holy shit. Perhaps for the first time in NPOCP history we have a car that is underpriced.

While the "never buy somebody else's project" axiom runs strong here, the price is at a reasonable enough point where another axiom holds true as well: "drive it 'til it breaks and at worst part it out." Finally, a

Meh, probably not a bad starting point for a tastefully done resto-mod weekender. Still, a little voice in my head is whispering "no" about that roof. The other body mods make me wonder if it wasn't in a bad front-end collision resulting in a new engine and mis-matched bodywork.

This has some pickup in it...
