[QUOTE="Tom-TPC Racing;11418329"]There's more than one way to setup a car. It is my preference to setup the front geometry so that I don't have to run a stiffer rear sway bar for push, which this car had. Not only did I got rid for the GT2 rear bar for the stock .1GT3 rear bar, I also added a stiffer front bar for more rear grip.

Oops... This setup is counter to conventional 911 thinking. Can you explain a little more about your setup and what the car now does as a result of your changes?

My suspension evolution went from full stiff rear, to full soft rear. I thought the car was really pushy when I first got it. If you drive the car timidly it will push through the corners, but once you start braking really late into the corners you realize how much grip the front really has, and how the car likes to rotate. This is where the soft rear bar is helpful to attain as much rear grip as possible. Adding a stiff front bar helps set the car on turn-in. Since all of the weight is on the outside front wheel, this will help keep the grip more evenly distributed over the other 3 wheels and level the car out. Keep in mind that this scenario is during heavy trailbraking.
Sorry if I spoke out of turn here. This setup works though.

Hey Brent. Thanks! I used Berkebile Gum Cutter and Simple Green. The Gum Cutter removes varnish like a champ and remove the skin off my hands too!

Once you get really fast with this car, you'll get it. This setup is only counter to conventional 911 "forum" thinking where most "racing" is done on the street.

Protocav is 100% correct. This setup doesn't work good for conventional "text book" driving method taught by many clubs, it'll push like crazy! It is much more common in Pro racing and top Club racers. And advanced level track day guys who either got coached by a pro or had their car setup by a race team to adapt to this driving style. Lally, Pobst, Pumpelly...I worked with these guys they take their braking Deep Deep into the corners. Pumpelly doesn't call this trail braking because the braking taken way Deep while turning that it doesn't fit the definition of the term. He was the first person to call this "Bending the car into the corner".

Time to get some sleep.

Bilstein Clubsports. Great choice, Im doing these as well. Drove the sharkwerks gt3 that has them and the setup is how the gt3 should have come from the factory.

Taking a break from suspension...
This was the shirt I used to clean 7 years of thilth off the alcantara steering wheel and shift ****. Oh, and I changed the clutch too because it was worn so thin that even with the clutch pedal hard to the floor it was very hard to shift. I just put a stock clutch in it and kept the stock flywheel because I can't afford to buy anything else after the shocks& springs. The shifting was improved with a new clutch.
