All right here is the situation, a friend bought Flash68 996tt here on the board and basically it has Alpha 28 and water/meth injection with pss10 and it is converted to 2wd.

My friend tried the car on the track and said that it was really hard to drive. I read pretty much all the threads there is on the subject and it seems like the cheap 2wd conversion for the track isn't all that great.

Now the problem is we don't have the parts to put it back to 4wd, of course, we could buy the parts but it would cost almost the same as installing a LSD.

Now what would you guys do, would you go back to 4wd or just try to go with the LSD for the same price? I read that for the car to run really good with the 2wd, you need to mess a lot with the suspension on top of having the LSD. Anyone has any experience with this? I read about soeem front GT2 suspension parts and such, anyone care to explain? I know it has some upgraded swaybars but that's all i know.

He wants a car that can be driven both on the track and on the road, it will see at least 5-6 days of track a year and don't want to have to mess for 2 years before he finds the perfect balance of the suspension and settings.

thanks for your feedbacks.

 

You could buy driveshaft/diff/axles used for a lot less then a LSD I guess?

 

What do you mean "hard to drive"? Clutch? handling? power?

 

coming out of turn, unable to put the power down. From the mods, i would guess the car makes between 600-700hp so it is a lot of power to throw in a curve with just one wheel with traction.

He tried my car before (still awd) and said it was easier to come out of turn and easier to use the power available. (i have less power but i am still on k16/24 at 1.1 bar)

 

You don't need any GT2 parts, you just need a coil-over suspension. If the car already has a coil-over installed, get it corner-balanced, install a LSD and call it a day.

 

Drove a 2wd 996TT yesterday. Muuuuch more fun than the AWD. He had the LSD, coil-over and 325/30/19's on the rear. I was going 2wd myself, but got an offer on the car today so it's going to a new home.

 

os gilken lsd 1700$ install 600-800$ problem fixed

 

I would keep it 2WD and set it up properly.

I can't see an AWD 911 being better than a properly setup RWD car on the track.

With all that weight over the rear wheels, and a short wheel base the car should not have any problem putting down the power. You can't expect to just go to RWD and have it be awesome on the track. Suspension & alignment need to be addressed.

Now if you are talking about something like a GTR with a *proper* AWD system and diffs that's a different story. But I don't believe the AWD system in a Porsche 996 provides much value.

 

ok so is the LSD really the only thing needed? He already has a set of pss10 and some sway bars, what else should be tried? what kind of settings should we start with, let say the LSD is installed?

The difference is going to be that major with the lsd?

 

I repeat; corner-balancing.

 

You should contact Stan at Gbox.

 

I subscribe to this interesting thread

 

Spring rates on the PSS10 are made for street and could be too soft. Softer springs = more oversteer. Dialing out oversteer is pretty easy though, just get some sway bars and a very good alignment. The rest is up to you.

 

I will give the opposing view as I have a GT700 and have run many track days. Even with Hoosiers and AWD there are slow speed corners where I spin all four wheels coming out.

I like having the all wheel drive and outrun all but dedicated race cars on the track.

Different ways to accomplish the same goal I guess. I do have KW v3 coilovers and sways front and rear.

 

Shipping a gearbox across the border can be a bit of a pain in the ****. Talk to Fiorano racing up there in Canada if you are considering putting an LSD in the car. They can easily install one for you.
