Weight difference between Berlinetta and Spider....

[Mario149]

....for an F355?

It's curiosity thing really. Spiders are always heavier than their tin top counterparts, but I can't seem to find any info on how much more my Spider weighs. Ferrari website has them both the same:

Anyone know?

Wondered about this myself too! All the performance figures are the same too!

Maybe the roof is that heavy on the berlinetta that after the strengthening on the spider, the lack of roof counterbalances the weight???

The whole weight thing popped into my mind the other day when my friend and I had a little straight line fun with him in his 996 911 C2 (coupe). We were both 2-up with similar total occupant weights and my 355 Spider slightly had the legs on him from a rolling start of about 20 mph. In theory not entirely surprising since the 355 Spider is supposed to be about 60bhp up on a 996, but when you factor in:

1) 996 C2 curb weight is 1320 kg and F355 Berlinetta dry weight is 1350kg. So realistically add 100kg for having the roof chopped off and another 50kg fluids/fuel, you're talking a more realistic number of 1500kg

2) no F355 or 360 has ever actually been dyno-ed at anywhere near their quoted power, whereas with Porsche, their figures pretty much seem to be the *minimum* you get when it leaves Stuttgart

....it was actually quite a pleasant surprise to be pulling away Although my mate wasn't too upset as he had a prime view of my exhaust flame action when changing up

Yeah the flame action is always a nice consolation prize!!!

Maybe there isn't much in the weight as the chassis might be strong enough to begin with. Might just be handling that suffers... unless you get Damon Hill to set it up for you of course!!!

I know someone who is getting a dyno built at their garage, so tempted to get it dyno'd before I let her go. Might do it once with the decat pipes still on and then again when they've been removed and cats on again. Would be interesting to see the difference!

Do local councils not have machines for weighing vehicles?

I am sure I have seen something like this at the waste disposal centre.

Are you really referring to OP's 355 ?

Too sharp Sir, too sharp.

I am being seriously serious - have a wander into your local waste refuge/ collection type facility - you may be able to get your vehicle weighed there.

My '98 355 F1 Owners Manual shows kerb weights of

Berlinetta 1450kg
GTS 1460kg
Spider 1490kg

Looks like my guestimate wasn't far off Does it have any info on how much more the F1 might weigh than the manual?

I also have an F355 Owners Manual (for a '97 manual car) and the weights shown in that are the same as for the F1

Cool, thanks
