ManwithSupra Posted January 23, 2008 Share Posted January 23, 2008 http://www.seiboncarbon.com/pdut_detail2.asp How much of a weight advantage over stock parts would replacing the following be... Front Wings Doors Bonnet Rear Hatch Just wondered if its a good idea, thinking about putting the car on a diet (yes the interior as well, Carbon fibre seats etc... me going on a diet as well).

Chris Wilson Posted January 23, 2008 Share Posted January 23, 2008 The doors look like wet lay up "carbon" skins on stock steel inner panels, and as they don't quote weights it's going to be hard to give any figure unless someone has bought some or has stock.

Animal Posted January 23, 2008 Share Posted January 23, 2008 Front Wings Dunno, possibly not much, I didn't buy them Doors Loads, the stock ones weigh a ton Bonnet Bugger all. Maybe a kilogram or two if your lucky Rear Hatch Again, quite a lot, even with the glass and spoiler fitted there is a very noticeable difference in weight I'm afraid I've no actual figures for comparison, but trust me, the doors and boot are considerably lighter than stock. I keep meaning to pop into a weighbridge to see what the Supe comes in at with these parts, but it's kinda low down on the list of stuff to do Quote Link to comment Share on other sites More sharing options...
Al Massey Posted January 23, 2008 Share Posted January 23, 2008 ive been thinking the same for the past couple of weeks would be handy to know the weight save but doubt its a good ratio to costs Quote Link to comment Share on other sites More sharing options...

Gaz Walker Posted January 23, 2008 Share Posted January 23, 2008 The doors are easily 30kg+ each with the side impact protection... The wings won't be much lighter than stock, it'll be less than 1kg for the pair. Probably be able to measure it in grams! You can drop 20kg with a CF bootlid and lexan window easily too. Bonnet will not save much. The Varis one we do is 7.9kg, so saves nearly 4kg over stock. Gaz. Quote Link to comment Share on other sites More sharing options...
uzthedentist Posted January 23, 2008 Share Posted January 23, 2008 is it a good idea to lose 20kg from the back of the car though? Quote Link to comment Share on other sites More sharing options...
Gaz Walker Posted January 23, 2008 Share Posted January 23, 2008 is it a good idea to lose 20kg from the back of the car though? Not exactly. You could swap the battery to the boot like we did to give the car better weight distribution though Quote Link to comment Share on other sites More sharing options...
ManwithSupra Posted January 23, 2008 Author Share Posted January 23, 2008 Yeah i also want to make the weight distribution as best as i can for the supe is 50/50 the best or is it better having say 55% Rear 45% front? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 24, 2008 Share Posted January 24, 2008 If you can get a rear bias you are doing well Quote Link to comment Share on other sites More sharing options...
ManwithSupra Posted January 24, 2008 Author Share Posted January 24, 2008 What is the standard weight ratio then? Quote Link to comment Share on other sites More sharing options...
Chris Wilson Posted January 24, 2008 Share Posted January 24, 2008 I have seen quoted figures of 52% front 48% rear, but never seen them on the scales, more like 53% 47% best, nor have I found a stock TT as light as the specs cite Quote Link to comment Share on other sites More sharing options...
ManwithSupra Posted January 24, 2008 Author Share Posted January 24, 2008 So what would be the optimum distribution of weight? Quote Link to comment Share on other sites More sharing options...
colsoop Posted January 24, 2008 Share Posted January 24, 2008 So what would be the optimum distribution of weight? As above and how much weight would you need to shift from the front to achieve that ? Quote Link to comment Share on other sites More sharing options...
Gaz Walker Posted January 24, 2008 Share Posted January 24, 2008 I have seen quoted figures of 52% front 48% rear, but never seen them on the scales, more like 53% 47% best, nor have I found a stock TT as light as the specs cite The figures I've seen were this: "Handling was well tuned due at least in part to good weight distribution. The 2JZ-GE had 51% of its weight up front and 49% to the rear whereas the 2JZ-GTE 53% of its weight up front and 47% to the rear" Curb Weight: 2JZ-GE 3210 lb 1460 kg - Targa Roof + 40lbs / AT +55 lbs 2JZ-GTE 3505 lb 1580.9 kg - Targa Roof + 40lbs / AT +10 lbs Obviously these will not account for a tank of fuel... Using those figures as a reference would mean you would need to move roughly 47kg from the front, to the back on a TT car. Regards, Gaz.

ManwithSupra Posted January 25, 2008 Author Share Posted January 25, 2008 Moving 47kg to the rear would be difficult but not impossible i reckon. I would imagine a good start would be moving the battery to the rear perhaps an aluminium rad, carbon fibre bonnet - actualy thinking about this it poses a new question would you loose this weight if you went with a single tub? This could be turning into an expensive project lol, Quote Link to comment Share on other sites More sharing options...
razza Posted January 25, 2008 Share Posted January 25, 2008 A big sub and amps will help a bit I'm sure, might add to overall weight but should help even it out a bit... Quote Link to comment Share on other sites More sharing options...
