Ways of reducing the weight of our cars

(1/28) > >>

fuscobal:
Since I haven't seen a topic dedicated to this, I would like to start one and ask for everyone who has weight data of different components (OEM or aftermarket) to share them here. Loosing weight on our cars is beneficial for both straight line and circuit performance. Until now, some data can be found scattered on the forums about brakes and wheels but what about chairs, rear bench, body panels, exhaust, battery...? The data I have until now (measured by me or by others) :

- GTI front brake system > aprox 15Kg/corner
- R32/S3/Cupra front brake system > aprox 21.5Kg/corner
- Aftermarket 4&6 pot brake systems > 10-13Kg/corner
- Carbotech RP2 brake pads for R32 calipers > 1.126Kg/set (0.563Kg/pc)
- GTI rear bench > 27.5Kg
- GTI rear seat board > 1-2Kg (estimated)
- OEM 17" Denvers > 10.5Kg/pc
- OEM 18" Detroit > 12.5Kg/pc
- OEM 17" + 225/45/17 winter tires > 23Kg/pc
- BBS RS-GT 19" + 235/35/19 summer tires > 21Kg/pc
- OEM DMF flywheel > 11Kg
- Sachs SRS SMF flywheel > 7.2Kg

This needs checking but IIRC approx 10kg is saved by replacing the oem steel bonnet with a double-skin carbonfibre one.

Chucking away the bonnet liner also saves a little weight.

Monza 17's weigh 11kg, Monza 18's weigh 12kg, and the lightest 18's are 8kg - All without tyres.

The oem engine cover weighs a ton but you have to take into account the weight of an aftermarket intake, but the Forge Twintake for example is very light.

....I'm pretty sure that's a single skin carbon bonnet and also I don't think that VWR don't offer them any longer. Availability would need checking.

danishmkvgti:
Single skin referring to a dual part bonnet. As this (VWR) doesn't use glassfiber as used in your OSIR product, the VWR is a real  Carbon bonnet and not single or dual CF bonnet.
A single skin CF bonnet is only CF on the outside and you can see the glassfiber on the inside, whereas a dual skin is 3 layer, CF on top then Glassfiber core and the CF on the inside for show  :happy2:
