Re: DW's (new?) Sierra 3dr YB race car

not being rude to you dave having meet you im not saying youre overweight atall this is just a point in general and is pretty irelevant i suppose as im assuming the cars are weighed minus driver but it makes me laugh when people say their buying carbon fibre bits for their car to save a kg when really just going for a jog once a week and watching what they eat would save the weight and make them a better driver all round through being in better health?

nothing to worry about theres not too much spare meat on dave

I had the Compomotive ML wheels and lost 10kg when changed them to split ML's. What kind of front discs do you have?

i have 6 pot billet Hi spec calipers with 335x32mm discs. Quite big I know but as I say I think they are worth it

My wheels are 9x17 dynamics as fitted to current touring cars.

i'd go down argos and buy 8 sets of cheap bathroom scales,

We do have a weigh bridge at work, pity its not more local though

Re: DW's (new?) Sierra N/A PINTO race car

i'd go down argos and buy 8 sets of cheap bathroom scales, find a scaffold plank from somewhere cut it into 4 short lengths just long enough to lay across two sets of scales, put sets of two under each wheel and there go an instant weighbridge

that how i weighed my trailor

Re: DW's (new?) Sierra N/A PINTO race car

Might be worth getting a dummy setup with everything fitted (even if not running) and taking it down a weighbrige to find out how much it weighs and go from there. If all else fails we have a pallet truck at work that can weight over 1000kg so drop it off at canary wharf and I'll jack it up for you

Re: DW's (new?) Sierra N/A PINTO race car

Where we stand with the car weight wise is that when I first took it to brands last year it was bang on 1000kg, after which I tried to remove a few more bits of weight from brackets, cutting out the bumpers etc. Probably didn't go down a lot though.

Obviously that 1000kg was with the pinto and type 9. A cossie lump, turbo, intercooler and T5 add weight but the dry sump set up has gone now which gets me a bit back..

Firstly thanks for the replies / thoughts chaps, it is a bit of a brain teaser.

Where we stand with the car weight wise is that when I first took it to brands last year it was bang on 1000kg, after which I tried to remove a few more bits of weight from brackets, cutting out the bumpers etc. Probably didn't go down a lot though.
I have a single skin fibreglass bonnet and tailgate, the windows are perpex, the doors are cut out a lot and the front bumper is carbon kevlar wih the rear being a origional with all of the internals cut out.
Whaletail is fibreglass and half the weight of the origional.
'Bolt on' weight loss would come from fibreglass front wings, doors and a perspex screen, but I doubt the doors and wings are that much lighter and I'm not a massive fan of plastic screens due to scratching etc. I guess if I fit a new screen every year it might be ok, and I could also lose a wiper and most of the mechanism but again the std setup works really nice and bad vision has never been an issue.

I have large brakes on the front but am not removing them for smaller ones at any cost, out braking is one of the cars strengths, besides they are billet anyway. The rears are std so work well but could be replaced with something a bit lighter but again at a cost. A nice small billet rear caliper would be nice though.

Don't know how much the wheels weigh compared to splits but they aren't the heaviest I've seen. Splits would be £1k+ too.
