Going lighter....

[danrx7]

Also get the lightest wheels that you can!
 
They will make a huge difference, on rotational inertia it helps leads and also it\'s less unsprung weight, so really help with the handling.
 
I\'ve been trying to find a site that lists wheel weights as well as pictures of just how bling they are.

 
Pretty comprehensive list of wheel weights, however no pics:

Cheers Dan, also found this:
http://www.superhonda.com/tech/wheel_weights.html

Which has a couple of lines:
Mazda RX7 FD3S Cast 16x8 15.4
Mazda RX7 FD3S - PFD Cast (Brittle) 16x8 13.8

So stock wheels (like all manufacturers it seems) are pretty light!

There is plenty of weight to be lost from the car, Ive lost over 300 kgs.

The diet is a good thing....Ive lost over 14kgs off me alone!

The general rule on unsprung weight it is for every 1kg lost is equivalent to 8kgs taken off the car!

It helps with acceleration, braking and turning.

But there are many ways, you have to decide how much of a road car you intend to keep.

Bonnet, wings, doors, tailgate, plexi glass.  These will all lose you weight.  My Corbeau seats (Carbon/Kevlar) were only £300 and are 6.3 kgs.  The Sparco Revs are even less than that, in both cost and weight.

There are other ways, making the car stiffer will help, if what you are after is quicker lap times.

If you want some light wheels Im buying some Speedline Mags, they are £295 per wheel and at 6.5kgs each....saves you 36kgs on the car......almost 300kgs weight when moving.

DON\'T TAKE OUT THE AIRCON!!!!  These cars get hotter than most anyway cos of the way the engine works and where the engine is.  It doesn\'t way much, and if you don\'t want to load the engine too much, don\'t turn it on.  And the aircon rad might be infront of the rad, but seriously...  If the car is to be used as a comfortable daily driver, leave it in - at least try driving the car during summer without the aircon, and see how you get on before ripping it out.  It will prob only need a charge, and all will be well!

Weight saving - eat fewer pies.  easiest way to save 10kg\'s, and still have a car you can sell.  Put in less petrol.  remove the airpump and cat.  wear flip-flops.  Just don\'t rip out the aircon...

And saving 20kg\'s is less than 1.5% of the total car\'s weight - using the online calcs based on the weight of the car and 280hp, you would increase your 1/4 mile terminal by .06 seconds and .43 mph.  And you\'d get out of the car with a sweaty arse.  LOOOOOOONS!!!!!

you big girl cant you take the heat hahaha

*lol* nah - just like being coooool....

like, you may win the 1/4 by .06 seconds, but I\'ll get out still perfectly coiffured, cool to the touch, clothes still stylishly dry....  You will get out of your sweat soaked seat, staggering toward the beer tent, sobbing for water, leaving pools as the perspiration drains out of your waterlogged clothing...  Oh, yeah, that\'ll make you the winner.  You can have that win.  Allllllll yours. *grin*

Every journey starts with the first step!

So rip out that Aircon....then do the ABS....that will save you some weight!

[Archbish]

So the first thing the hospital will have to do is give you a bed bath to get rid of the stench, after you\'ve been cut out of your car, after suffering heat stroke and smashing into the barrier cos your brakes aren\'t as good...  *sigh* IT\'S THERE FOR A REASON, AND NOT JUST TO INCREASE YOUR CARBON FOOTPRINT!!  Even the Le Mans cars have Aircon these days...

Thanks for the advice everyone.

I\'m gonna take out the a/c as it doesn\'t work anyway. Does anyone have a \'how to\' that would be ok for a beginner like me to have a go at?
