barry.h Posted August 25, 2004 Share Posted August 25, 2004 I'd forgotten the hubs. As I recall they are over a kg heavier per side than alloy hubs. Also I've made my own wing stays out of duralumin which saves a bit as well. The tonneau for the boot is 0.8mm aluminium sheet and no boot floor - another kg saved!! And saddest of all - no nosecone grille *eek* Barry Link to comment Share on other sites More sharing options...
Violet Elizabeth Posted August 25, 2004 Share Posted August 25, 2004 Ooo, haven't weighed the grill yet ! 60g saving by fitting a carbon fibre tax disk holder Vinyl number plate instead of plastic plate must save a few hundred. Link to comment Share on other sites More sharing options...
Mike Molloy Posted August 25, 2004 Share Posted August 25, 2004 The front hubs and brakes are an area of concern at the mo as I am having problems with brakes binding (see separate thread). However, in terms of upgrades, unsprung weight loss is even more of a holy grail. I was thinking about the Caterham uprated ally hubs, but they seem to be more about brute strength to withstand R400 racing abuse than light weight. I would also guess the AP 4-pots and vented discs are heavy and overkill for a light car. I'd be interested to investigate the ideas of 2-pot calipers mated to thin (and *light*) bike-derived floating discs. Anybody got any thoughts on this route? Would a thin solid, disc dissipate the heat from circuit use? Link to comment Share on other sites More sharing options...
Joe 90 Posted August 25, 2004 Share Posted August 25, 2004 Standard solid disks are mandatory for a lot of racing classes, such as all the grads series like megagrads. Front disk temperatures are manageable even with full on racing. My car has standard disks and Wilwood 4 pot calipers, which is a big improvement in terms of weight.

Morls Posted August 26, 2004 Share Posted August 26, 2004 The weight difference between my home made loom and a Caterham K series one is shocking, probably far more than that which could be gained by changing all the GRP to CF, and for about £20 worth of wire, tape and terminals from Maplin / RS. My rear lights (the Lucas type as fitted by Lotus in the 60s ) are far lighter and much prettier than the standard Caterham/Caravan things... there's progress The Honda fusebox and relay rack are matchbox sized (and of similar mass) against the Caterham things which are larger than a family sized pie Mmmmmm....

dino ferrana Posted August 26, 2004 Share Posted August 26, 2004 To be fair to Caterham on the lights issue they have to take what is available and currenly able to pass SVA. They cannot develop their own light units as they would cost hundreds of thousands (seriously). Link to comment Share on other sites More sharing options...
moomin Posted August 26, 2004 Share Posted August 26, 2004 As you know my Blackbird weighs in at 388.5 kgs (or 385 with smaller rear wheels) so Richard's Fireblade - depending on how much trim it is carrying - could be a bit lighter. Crikey, given that a BB engine weighs ~30kgs more than an FB engine, that is rather good going...! moomin www.megabird.co.uk Link to comment Share on other sites More sharing options...
