Ok, so got my DC5 weighed on a weight bridge at the local scrappy (I imagine these are calibrated?) and the DC5 came in at 1140kg with half a tank of fuel.

Items changed but otherwise stock:

Odyssey PC680 Battery - works absolutely fine and you wouldnt be able to tell the difference over the stock battery.
AC Removed.
Power steering removed and CTR electric fitted.
K-Tuned alt relocate kit - no heavy auto belt tensioner etc.
4-2-1 1320 SS header. This saved 8kg alone over the original header.

The plan is to get it below 1100kg but without sacrificing anything? Another 40kg saving is a big ask without going stupid, any small things that could be done?
Problem i found is that everything in the dc5 on its own is light, so you have to remove quite a bit to make a difference.
Coilovers, lighter wheels and bucket seats are probably best bet.
My new wheels were 12kgs lighter than my rotas and my seats were 9/10kgs lighter each. So thats ~32kgs there, i've not weighed my coilovers but they were a fair bit lighter than oem shocks/springs.

Cheers, I have been considering some fixed buckets and fixed rails to get the weight down, I think this is one of the biggest single areas of savings on the car.
I will keep the original wheels and am considering remaking some steel stuff in alloy.

Some ideas at the moment:

Front engine mount in alloy - approx 0.8kg saving.

Rear LCA's - ive heard 2kg quoted.

Front discs with alloy disc bells - should be about 1kg or so.

Seats - as mentioned above - 18-20kg

remove lower section of rear seat - must be a couple kg there.

Rear seat belts must be a kg or so.

That should be 23-24kg so far.

Are there any aftermarket parts that people want/need a weight for?

I weighed some of the ultra light flys to find out the lightest- (These weights where measured on the actual item using a pretty acurate scale- but it could be that manufactureres change designs/materials so weight could change.)


Competition Clutch Ultra Lightweight Flywheel (5KG) - Honda K-Series = 4.035KG

ACT Prolite- 3.545Kg

Exedy Racing HF02 - 4.15KG

If anyone wants me to weigh other things drop me a PM

Just rounded it up mate as that was the total weight for one I shipped out with the bolts and trim etc, bar is same as the rep so 1.6-1.7kg's, then 4 bolts and trim

Mugen Rear Mid Brace (alone without fittings) 1.7kg
Honda Cargo net is adding is around 5g's (max)
Fujitsibu RM01'A with all fittings, bolts, gaskets - 8.8kg (some sites say 9.5kg I believe this is with packaging as I checked mine before fitting and it was 8.8kgs)
OEM Honda Catback system - 14.1kg
