YAYfor me

I need to lighten my car and make it handle better, Who makes suspension parts that are lighter than stock??

links?


leprochauns?

 

Since the unsprung parts on the Z are mostly aluminum already, you are going to have a tough time shaving off much weight that way. If you do find lighter parts they will be very expensive.

You could start with lighter wheels which will reduce unsprung weight and look cool.

good luck.

 

there are other ways to lose weight on the car...as said, your not going lose much suspension wise

 

rsr titanium springs

 

I have the RSR titaniums and they look great

 

Fine, If there is no weight to be shed threre, then you cant lighten the Z's front end at all

CF bumper? almost the same

CF hood?
SAME

There is no freaking way to lighten this heavy pig of a car and i hate that, maybe i just need to go get a Z4

any lighter??

 

i'm sure if you got some cf fenders it would lighten it up a bit. but your best bet is lightweight rims, and i'm not sure how heavy the brakes are, but if you had cash, carbon brakes. if you're going to track the car, i think performance nissan was selling cf headlight covers, so that you take out the housings.

 

axxizzer -- Amuse built a Z that weighs sub-3,000 lb. (same as the Z4) by doing Ti exhaust, CF doors, fenders, hood, seats.

 

Fenders don't weigh much, and a CF option wouldn't give you more than a pound or two. Ways to lighten the front end? Remove the A/C, P/S, use a lightweight battery... there are lots of ways, but they come at the expense of daily luxuries...

 

with CF doors it isnt street legal


I micht just sell this car and get an AA supercharged Z4

Or maybe not....

I jsut wish that it could get ANY lighter



oh and the amuse also has a CF hatch that lightens it by about 50lbs



AND SCREWS UP THE BALANCE LIKE THERES NO TOMORROW

 

What would be the drawbacks of a lighter battery? Service Life, cranking power? I'm thinking of the odyssey battery to shave off 20lbs.

How much lighter are the RSR Ti springs than a set of stock springs?

 

If you really want to lighten the front end, first install a lightweight exhaust then relocate the battery to the trunk in a plastic battery case available thru summitracing for about 100.00

NHRA and SCCA both have sections that address relocated batteries so consult those rules if you plan on racing it.

 

if you did the lightweight battery and put it somewhere in the rear, and then got the cf hatch the weight balance would not be affected too much. and you'd save something like 70 pounds.

then get some lightweight wheels, 18's at most. you could get the nismos which are like 17lbs each and save like 40 pounds off the stock wheels (i think the stocks weigh like 27 pounds right?).

that's already 110 pounds without throwing off the weight balance too much.

 

I know about some ULTRA light weight Koni race shocks that weigh like 1/3 of OEM.


Start the applications for a 2nd home mortgage!

 

how much are those koni "RACE" shocks and where can i find them? i have seen the regular yallow street shocs that are softer than stock, i don't mean those. What's this race shock you talk of? Is it like Moton,or penske, reall expensive?

 

They are Koni's, and they weigh 5 lbs LESS than Motons!

4, yes, four way adjustible!

ONLY about $1,700 each!

I took some pixs that I'll post later.

 

Easy ways to lighten the car would be:

-Exhaust system
-Seats
-Wheels
-Tires
-Spare Tire Stuff

An average racing seat is 10-15lbs, I imagine the stock ones are closer to 30+.

The stock muffler by itself is ~37lbs. The N1 muffler I bought and welded in its place is 6lbs. 31lbs savings right there and I'm still using the stock piping and resonator.

In addition you can save 5-10lbs per wheel by going to Volks, provided you don't try and be all bling bling by getting 19's.. You can get very light 17x8's for a reasonable price. If you are racing, Hoosier R or A series tires are a lot lighter than most other tires as well. And if you are racing, you can ditch the stuff in the spare tire area.

And if you're really desperate, empty the washer fluid tank.. that's probably 5-10lbs too. All of this stuff added up would probably be close to 100-120lbs, which brings the curb weight down to a reasonable weight.

Most of this stuff (hoosier tires for ex.) will make a difference if you're autocrossing or doing track events. I don't see why you'd need to go to extreme lengths if you are just driving on the street everyday.

 

There are ways. You can easily lighten your front by 24 pounds by installing lightweight battery. Lightweight lights assembly, nismo-style, will sure save a lot. When they start selling it. Also Aluminum radiator might help.
