Who has the lightest 370z?

pne

Hi guys. I am wondering who has the lightest Z car here?

I test drove a 370z last month and really liked it. As a package I think it's a killer car. Right now I am driving a miata which is a lot of fun, but lacking in power. I've already started the ball rolling to turbo it. But I'm spending a ton of money to build a not so reliable car. $2k for suspension, $2k bbk, $5k turbo kit/tune, $2k wider wheels/rubber, $2k clutch etc.

Then I got thinking, why not just buy a 370z and strip it, spend all that money on lightweight parts rather than turning my miata into a grenade? So what do you guys think, with $11 grand in aftermarket to work with, could I shave a 370Z down about 2800lbs? I'm thinking stripped interior, race seats, lightweight wheels, and carbon goodies.

There are a few members on the forum who use their Z as dedicated Track cars. I suppose following them would give you the best idea of what's obtainable.

TravisJB comes to mind first TravisJB Journal

Other than that...I'd probably stick with the Miata build rather than stripping down a Z. I've looked into Miata's before and I don't see how those parts are costing so much...

ccdominic

you looking to maybe make it forced induction?

kenchan

in 2012 the 370Z's weight and dimension is not a huge deal.

just get the Z and enjoy it.

Yeah miata parts shouldn't be running you that high where do you buy parts?

What is your overall goal? Just curious. Are you building a track car?

Sub-3000 is tough in the 370z unless you are ready to remove some features like AC, strip the car and remove certain parts or replace with dry carbon fiber.
Now, if this is a track only car then I say go for it. The Z is a fairly solid platform to build on but it will be more expensive than your Miata.

It's a track/summer car, but I don't plan to race it and don't want to cage it. I had no plans to turbo the 370 if I bought one, they are pretty quick out of the box and I think if I could get it under 3000 even, it would be enough for me. TravisJB's car looks sick, I can't find if he put that thing on a scale?

Miata is going to be a better and cheaper track car. It's been used in motorsports for years and aftermarket is awesome and well proven. 370z not so much.

Without a cage getting just under 3000 lbs is pretty easy. Lightweight wheels and lighter dot r tires, aluminum hat brake rotors, lightweight flywheel and clutch, aluminum body Coilovers with small springs, lightweight long tube headers and exhuast system, lightweight race seats, lightweight battery, racing steering wheel, remove all engine dressing, CF hood, remove stereo and speakers, lose spare and all associated stuff in the back, replace stock mirrors with lightweight race mirrors, Lightweight engine pullies and belts everywhere, hollow swaybars, use titanium harness bar to replace stock beam behind the seats, replacing steel nuts, bolts, brackets on non load bearing with titanium or aluminum, lightweight intakes.

More radical weight removal would include stripping interior and doors, doing CF rear deck with poly window, poly side windows, cf fenders, remove AC, lightweight radiator, get a racing alternator, remove heater core and all plumbing, strip all undercoating and sealer, remove plastic fender liners, composite fuel cell, remove all sound deadening material, CF doors, replace projection beam headlight buckets etc with lightweight LED headlights, remove crash bars (not advisable), I'm sure theres more.

I have seen a 2650 lb 370z with full cage.

2800 lbs Z.. remove the doors and replace with custom carbon fiber sheets, remove all of the interior, no ac, remove radio, light wheels/tires, get rid of the hood, carbon fiber replacements for anything possible. replace any remaining glass with resin/plastic, no muffler, small battery, custom make smaller gas tank (10 gallons) That may get you close.

Still think you're better off turboing the Miata for what you're looking for. A worked Miata putting down 250-300 whp would be absolutely ridiculous from a performance standpoint...

Making the Z that light is going to make it pretty much a Track dependent car unless you like driving around in an empty shell and motor.
