Feel free to add to this. ie interior, flywheels, manifolds........ anything that was lighter then what was there.



Removal of engine bay aircon parts.
Aircon radiator, bracket, pump, belt, pulley, filter, pipes, bolts.
SAVED 13.6kg

might put it back in when summer comes around, removed as it had been removed before and put back in with engine swap, so no gas anyway.

Missed the cockpit heat exchanger unit under the dash for some extra weight saving:thumbs: and if you want to lose sum more weight get scrapping with the use of a hot air gun to remove the sound deadening (lots of elbow grease required) there's enough of it and really does add up to considerable weight.

spare wheel - god knows how much, but once you upgrade your brakes you may as well bin it as it won't fit anyway....

Along with the tools, jack and the jack holder :) weighs next to nothing but there's no point having it in there if you have no spare wheel. The only disadvantage to removing the wheel is that the boot floor becomes slightly useless as the wood just bends. Last weekend I began carefully peeling some if the sound deadening from the boot too without scratching the paint! Again, there's not much point having that with an exhaust system that has only 1 silencer. surprising how much it weighs too.

I might check that out mate, I run a fecking great 18" Rota GTR to clear the front brakes which makes the boot even more useless :D

i just picked up some second hand spacers off a S14 and had a 4mm slip-on in the shed, much lighter and cheaper then getting another wheel

I've been driving for nearly 8 years now, covering probably 18k miles per year and have never had a puncture which necessitated changing the wheel. New cars generally come with runflats or a can if foam instead of a wheel now!

I've stripped all the tar sound proofing out of my 15 then laid the carpet back down as it weighs nothing and adds a little comfort :) back seats are back in but i did have them out for 6 months prior! Drivers side fixed Bride which weighs almost nothing, no seat belts, no airbags, boot is empty too... amazing what a difference removing all that made (in terms of lightness and noise haha!) my exhaust is 3" turbo back, decat with a NurSpecR... its loud and i love it :) haha

Can't wait to strip everything out of my track car... aircon delete, radio + most of centre console delete, spare wheel delete, interior trim (90%) delete...



Although after picking up my Apex 6 point rollcage I bought the other day I think all that weight saving is completely lost after I get that welded in haha :wack:

True but it would be heaver if you left that all in, in a fast fours article a guy saved 80kg out from his S14 by removing basically everything you are doing or are going to do.

Yep - just removed all the interior last week when I started on the S14 at Speed Factory. Out went all the seats, trim, door cards, boot trim, spare wheel... only thing left is the dash and parts of the centre console.

Not sure how much this weighed but not convinced it was 80kg unless you included the original seats lol?! The rear seat is not that heavy surprisingly!!


Can't wait to get rollcage bolted and welded in plus removal of aircon :)

you can go too mad imo - if its still a street car, those savings are lost as soon as a passenger gets in....

If you have access to some dry ice....chop it up into some pieces and let it sit on the sound deadening material for about 10 minutes and then use a screwdriver and pry it up in one piece pretty easily. :thumbs:

SAFETY ADVICE...wear some leather gloves

dry ice is also good for making safe explosions, smash it down to bread crumb size then tip about 2 table spoons of it into a coke bottle, then very very very quickly add water the screw the lid on and throw, fire in the hole type approach works best
