[QUOTE="tt335ci03cobra, post: 16103209, member: 68944"] With the downforce on the carbon car, I assume 3-4mph is being weighed out. I think at 135mph, it’s probably generating 250-300lbs of downforce. If the carbon car weighs 3950lbs, but that spoiler adds down force which makes it “heavy” you’ll get those numbers you describe. I have a gut hunch the base car is +/- 4069lbs, and the carbon car is +/- 3975. It’s a gut bunch, but I think they went non painted wheel (exposed carbon) to get the “magic” identical wheel weight of the painted 19” gt350r carbon wheel. The carbon getting only 2 seats shaves 30lbs, the wheels another 40lbs vs the 20” aluminum wheels, and I’d guess the carbon wing is roughly the same weight as the base cars traditional material spoiler. Here’s where I think the 4069lbs comes in from a gt350@3800lbs. •dct + 120lbs •blower with coolers + 90lbs •16” brakes + 10lbs (1” bigger) •20” wheels +10lbs (1” bigger) •oil/trans/diff/lines coolers +60lbs •hubs/knuckles + 15lbs •bigger exhaust but no balancers 0lbs •new front clip -15lbs •no clutch pedal or handbrake or shift lever -15lbs •carbon driveshaft -5lbs +/- 270lbs. If the dct is obnoxiously heavy, then a base car could be 4100. I’m assuming it weighs about 282lbs without the driveshaft, not unlike a Ford gt 7dcl750. Keep in mind a gt350 has an aluminum driveshaft. I understand the 7dcl750 is a transaxle. •7Dcl750 (Ford gt): 120kg is 282lbs... but, that’s with fluid and clutches. The t3160 140lbs is dry without a clutch pedal so about 160lbs. 120lbs difference. Now I’m sure small differences like thicker sway bar or beefier control arm mounts or bracing exist, but I’m also sure I’m forgetting some weight savings where ford likely pulled a card from the GT program and carefuly whittled put some unneeded material from cross braces under the car (cut out small geometric shapes from a wide band of material etc). [USER=83412]@Tob[/USER] what are your thoughts on weight? You have a better and more mind and the hands on experience for these sorts of calculations. [/QUOTE]
