GT2 seems to have more issue than the turbo due to the large rear spoiler.

 

You can proudly pound your chest anytime you'd like.

 

Hey,Thanks,,I just learned something new...I would have thought a GT2 would have a better set-up for high speed stability in high speed straights......

 

The added rear downforce really upsets the front end.

 

yup...also needing more power than the turbo at those higher speeds.

 

HI,It makes sense,thanks...When I put a Tech Art rear whale tail wing on my previous super charged 2002 C2 it did not feel like it pulled as hard and felt slightly different on the big end,above 165mph or so, as with out it??

 

So you've been over 190 multiple times? Where do you get a chance to do that in your neck of the woods? I've been in Chicago since Friday and lived here for a few years back in early 2000. I'm just wondering where your "Mexico" is.

 

Makes sence. Wondering if my Turbo would have more ultra high speed stability (>165mph) with the rear spoiler in the down position?

Logic tells me with the rear wing up more down force is created on the rear possibly lightening up the front. For straight line top speeds, I'd think you want the max down force on the front for steering feel and less float and the rear with the weight over the axle seems to be taken care of.

 

I always remove my wing or remove the wing fuse during my high speed runs.

Notice my wing removed here.

 

i think the problem with the GT2 rear wing is that it is vulnerable to crosswind.A heavy crosswind catches the pieces of the wing that hang down on the sides causing the car to move around.Either way the 911 in particular moves around mostly because of its short wheelbase and rear weight bias.Then add in big power and you can have some fun over 200 mph.

 

This.

 

ok, i understand that. so it would be in my better interest to swap the stock decklid on, but keep wing in down position?

also, i have read about removing door mirrors, and have found this simple DIY, can anyone confirm?any other tricks or suggestions from those that have run. I have found this as a pretty useful repository so far for people looking to get into the mile (myself)

 

HI,,Driving on 90west out of Chicago towards Rockford,,,On 39 between 88 and 80,,,Driving 94 west(Northbrook area)into the stretch into 294 tollway towards Wisconsin....I have only got up to 190 once so far,then ran out of room....But 180,185 a dozen or so times.....Hoping for room for the 200mph .....lol.....

 

Looks like u have a turbo?The turbo if ot has stock bodywork with a Gt2 wingit would be betterto runwith tbe stock decklid because the added rear downforce will upset the overall balance of the car.I like to runwith the wing operational(ive done it both ways)as the car just feels better but will probably.sacrifice a few mph above 200

 

Catch 22 - compromise. Big wing = more down-force for corners = more drag for top speed.
