Does a front splitter reduce understeer on a stock GTS? Disclaimer: I am not an expert in anything related to downforce, suspension, tires ...
So with all the recent threads about installing front splitters on a stock GTS fascia, does a front splitter reduce understeer on such a street (versus track) car driven on a roadcourse? Thinking with more downforce, it should grip better and hence reduce understeer in fast corners.
Be gentle
Detlef: That is EXACTLY one thing that a front (and rear) aero-devices can do. But they need airspeed to work! And the results vary as speed varies.
Front (and side) SPLITTERS help divide (split) the arflow to minimize and eliminate LIFT. and minimize DRAG. While technically this is not CREATING RAW downforce, the net result is the same: More grip.
The adjustable airfoil BLADE of the ACR Front Splitter device (for example) can be adjusted to increase or decrease downforce. Adjusted wrong, it can create LIFT and launch you. It is not to be trifled with. And should NOT be used at high speeds without a balancing rear downforce device.
Canards, or Dive Planes, create true downforce (and drag), giving the tires more grip.
Sidesplitter 'skirts' divert air from spilling up along the sills and doors and creating rear wheel-well drag and lift. Again, minimizing LIFT is virtually synonymous with creating downforce. But it varies with speed. And the it can 'disappear' at certian speeds!
Rear Diffusers DITTO...they prompt the air to stay low and away, eliminating the vacuum pocket 'void' in airstream aft of the car.
Paul's hint to imnprove your CONTACT PATCHES first is valid...and that starts with stickier rubber AND a performance alignment.
Trivia: The 1996 GTS was the first to employ several air-dam aero devices under the front fascia, and the Cam-Tail spolier to 'balance' them at the rear. THis greatly improved the CD and top speed of the GTS vs the Gen 1 "Flying Bricks"
Was I gentle enuf (you clueless old thin-air-sucking rookie?!)
