He didnt say he had inside wheel lift from the rear, he said he had traction issues. One doesnt automatically = the other.

 

You could also try turning your coil overs a few clicks up on the front and dropping off a touch on the rear.

 

It's not a band-aid, it is a way to effectively MOVE grip from the front to the back.

If the car is oversteering, there's more grip up front than in back.
Adding a bar doesn't simply "remove grip from the front". It effectively ADDS grip to the rear by alleviating the load on the outside rear.

Its not the best way to achieve grip in the rear however so in my book its a band aid. Adding more grip in back without stiffening the front is the first and best solution without compromising front handing and or grip, you are removing grip from the front, or it wouldn’t be effective in what your trying to achieve. You need to think outside your box a little bit. If more tire isnt possible in back, then other options should be explored, such as sway bars, but its a compromise that may not have to be made.

 

But again your reducing grip up front = band aid.

 

Totally disagree with the notion that a stiffer front bar merely reduces front grip, or that a softer rear bare would merely add rear grip. Either mod affects grip at BOTH ends of the car.

 

Look, lets focus on the net effects of sway bars instead of the idiosyncrasies, sway bars effect weight transfer, weight transfer effects traction on a given end, the OP is experience lack of rear traction, so your telling him through utilization of a stiffer front sway to remove weight transfer from the front to the rear tires, effectively re balancing the cars traction, so now not only is the OP experiencing reduced traction from the rear then he was previously, your now inferring that he should reduce traction up front to re balance the cars adhesion at the limit, so now he is further compounding his available lack of traction at both ends of the car rather then just the rear. Why don’t we focus on how to regain the integrity of the rear solely and bring the whole car up to a higher level?

 

NO, a sway bar change *at either end* affects lateral weight transfer at *BOTH* ends of the car.

A stiffer front bar increases lateral transfer in front, and reduces it in the back by the same amount.

Total lateral weight transfer is ONLY affected by track width, c.g. height, and cornering g's.



Er, stiffer front bar ADDS weight transfer up front, and reduces it in the rear. Giving more rear grip by allowing the outside rear to operate in the more linear region of the grip/load curve.

NO, stiffer front bar will increase rear grip, not reduce it.

That's not what I'm *implying* at all. I'm saying that increasing front roll stiffness will increase rear grip. Alternatively he could reduce rear roll stiffness, or do a bit of both.

 

dude Zdan with all due respect your way over complicating things. Its very simple. As a base platform, stiffer rear sway and weaker front sway biases traction to the front making the car tail happy/loss of traction fist at the limit. Stiffer front sway and weaker rear holds the opposite true. Its proven in our very own car design between 00-01 ap1's and ap2's. You want to get into wheel lift and other variables to overcomplicate a simple issue, that’s your prerogative, but its counter productive. The best solution for the OP here as far as I see given his info is returning the rear toe more positive as it was previously, or add more tire in back. Leave the front alone. You change one thing and you effect another, I say let’s focus on the end of the car that is lacking first.

 

modulate your right foot better or make the car pushy with a huge ass swaybar, a ton of toe-in etc
