Im going to check the weight of the rear trunk spoiler.

 

Rear trunk spoiler from a 93 SC400 7lbs Sub woofer 6lbs.

 

Not to be a naysayer, but you're calculations are a bit optimistic. I've removed the spare+jack from my car and it weighed only 52 lbs according to several scales, about 46 lbs for the spare and 6 lbs for the jack. I've also weighed the stock seats and they are about 120 lbs total (55 passenger, 65 driver). Aftermarket seats can cut a good 70-80 lbs, but not much more than that.

From what I've been told, some of the biggest weight savings can be made by replacing the doors on our cars. One professional racer told me he weighed the door frame alone on each side at 62 lbs, not including all the additional components of the door.

I wouldn't remove the rear trunk spoiler. It cuts the drag coefficient down from 0.32 to 0.31. For just 6 lbs, its well worth it.

 

what r some of the tricks to getting weight off this car?

Lose weight

 

The plan for my sc400 is full strip, 5 speeds are lighter from what im reading, 1 piece drive shaft, replace seats with fixed buckets, sound deadening (should weigh a ton considering my fc had well over 60 pounds of it), rear seat delete, cd changer, spare, cruise control, emissions crap, relocate battery to rear passenger area to offset balance, and deleting that huge hydraulic fan!!! And probably rock no hood for drift events.

Only real additions to weight I'll be adding down the road will be a cage and some custom crash bars to replace the bumper supports. This is all in the works currently. Unfortunately I only have my iPhone and no computer to make a build thread with :sadface you guys think it'll get me under 3k without me in it?

 

15 pages. and i was hoping to read about a full drift car weight.

with CF doors, hood, trunk, and everything but neccessities kept

I dont think any of us can afford that...if anyone could ,they put that money on the engine and forced induction.

 

uhhh no one knows how much the ABS system weighs? At least the module.

 

i have lost 70 pounds since i bought my sc. lol

 

in the abs/trac delete thread the original person who did the diy did weigh everything. just gotta read the thread. its in the very first post. 43lbs.

 

oh cool, i didnt see that thread. Thanks.

 

When I purchased my 93 back in May, the prev. owner had bought a heavy duty group 27 battery that comp. fills the battery tray and weighs 48lbs. I sold it and bought a group 26 from Walmart 540 cca weighs 25 lbs. Spins the starter over as fast as the big battery and have lots more room around the battery tray area. Had to do slight hold down mod. to use the stock battery hold down, now looks O.E. Weightloss of 22lbs. Cost $49.95 & tax.
