50/50 weight distribution?[no]

[96'GSspyder]

Does anyone know the weight ratio for the 2G eclipse? I doubt its 50/50, but it is possible to make it such?

 

[2gGSX]

sure, add sandbags to the back until you get a 50/50 weight distribution

in all seriousness though, i dont think you can really get a 2g to 50/50 weight distribution..id personally prefer a 40/60

59/41 according to the Road & Track GSX road test sheet. It'll be a bit worse (2%?) on a FWD. As far-forward as that engine/transmision mass is, I don't know that shifting it rearward would help all that much. Polar moment of inertia and other physics terms should frighten you away.
Like so much other crap since 1980, it's mostly a FWD design. So despite countless hours of polishing, you're starting off with a turd.

are DSM's really that crappy of a design?

To be perfectly honest, FWD front-engine vehicles are packaged that way for cost-saving reasons more than anything else. Same idea with most strut suspensions. There are some positives (like increased traction in wet or icy weather) from having the engine over the drive wheels, but they mostly benefit average drivers on public roads, not racers trying to cut hundredths off the quarter mile or a couple tenths off road course lap times.

what about the AWD base?

rear weight bias helps straight line acceleration, and it evens out when braking..just my view of things

Do GSX's have a rear weight bias? I'd imagine that the GSX spyders have more weight in the rear since thats where all motors and stow gear for the top are.

I'd not go quite that far. It's just not a really good platform for an outstanding handler. The tradeoff is that the passenger compartment isn't cramped beyond being a small car, and the styling is very nice. It's just the modern manufacturing methods of making all these power unit cassettes and dropping different bodies onto them. Look at how much a DSM ISN'T like an S-2000 or a Miata.

I doubt the Spyder has as much ballast in the rear as an AWD.

 

[2gGSX]

GSX's definately dont have a rear weight bias...unless you add like sandbags
i was just saying for a road course or something id prefer a slight rear weight bias

corner weights of some DSMs.

Not flaming but you are 100% wrong. If you do the sensitivity calculations you will see that moving the mass forward is the number one thing you can do to increase straight line acceleration in a fwd car.

In a AWD model i would still want a front bias so when I am really on it I have about 50/50.

some people like to turn
the 2g's weight distribution is something like 54/46 according to that site you gave, not bad

The only time rear weight bias is good for straight line acceleration is on a RWD car, because you want the weight on top of the drive wheels upon launching. However, in a FWD car you want a front weight bias so that less weight transfers to the non-drive wheels upon launch. In an AWD car, you want just enough front weight bias so that upon launching the downward force on the car is evenly spread among the front and the rear.

I have a 95 Talon TSI AWD

As far as i know and what ive read, it should be 40 front 60 rear.

It should be the same im assuming for a GSX.

 

[cuttheduck]

you dont have 60 in the back and only 40 front.
Unless maby you took out your engine and tranny..

Gee, did you read any of the other posts in this thread?

Thanks for your opinions, despite how distantly off in space they are.



Talons, Eclipses and (within the generations) Lasers are the same car.

You might not know this, and I appoligize if you already do, but they never made GSX spyders from the factory. GSX spyders exist because some people took GST spyders and converted them to AWD.

Just an FYI!
