That's from my excel spreadsheet Nick, I'll update it with the latest figures and add to both threads periodically. I weighed a standard diff last night - but must have had a blonde moment because they certainly aren't 2.6Kg :oops:

Thank you for sharing the weights - they're all on my spreadsheet too ;)

Diffs 26kg more like!

When I add up everything I've binned, my car should be lighter than it is! All those little bits n bobs add up to a lot as well.

I've only just managed sub 75 at Curbs :-) (77 odd in a standard SE5, 76 odd in a standard SS1, 74 odd in the Ti with a leaking boost pipe in the pouring rain!)

Has anyone weighed an entire SS1 in either CVH, Ti, SSt or Sabre format? I've read various accounts of SS1's weighing in from 860kg in base spec up to nearly 1000kg for the Sabres and wondered what the different models actually weigh?

I'll get my Ti weighed at the local scrap yard as they've got a drive on weigh bridge, will post up the results when I have them.

My Sabre Ti was weighed by Steve Cork at 920 kg. I would expect an SS1 to be a bit lighter?

Over the last few years, as the Club has been operating a power/weight handicap system, all the compies will have weighed their cars for that purpose, and submitted the results. So there must be weights floating around somewhere - try a search in the competition section, I've got a vague feeling I remember seeing something there?

Your car has had the several kilos of lead (might be zinc) lined soundproofing removed though...

Ti's in standard form tend to vary between 920-980kg, dependant on wheels fitted, roll bar, hard/soft top etc. None drop below 900kg.

CVHs are lighter, but the ones that have competed in recent times have all been lightened to compete in ModProd, so their figures aren't accurate for a standard car (Nick Keyser, Jim Keyser for example)

Non galv cars are always lighter as only 70% of the chassis still exists in metallic form the rest is a red dust trailing behind as the car drives... :lol:
(apologies R-R, only kidding)

Its surprising the differences in component weights that make a big difference. Add a Ti foam spoiler, 15" wheels, change the seats, add hardtop with glass sunroof and the figures vary by 50kg easily.
std seats are mega heavy, especially as they aren't the last word in comfort!

Sabres seem to vary a lot too. The body thickness isn't uniform as hand lay up, where as at least SS1s are pretty uniform in the panel weights.
My SST was pretty thick GRP in sections but not others, depends if laid up Monday or Friday, and by Fred or Joe I guess :lol:

add in leccy mirrors, leccy windows and even door card furnishings and you can shave or add a good 20kg imho.

I know Chris 'Statto' Eades swapped door cards and window mechs form his parts bin onto his old CVH car, all added up to a weight saving within the regs

I couldn't believe the weight in the door trims on a Sabre - they weigh a ton compared to the svelte foam cards on an SS1..
