Just finished swapping a 34 mm bar up front and the 24 mm bar in the back. This replaced the 29 mm front and 19 mm rear bars the car came with. I also put new Federal-Mogul polyurethane end links on both bars, and WHAT A DIFFERENCE!! Before the swap, the car would roll away from turns very badly. Now, nothing moves at all as far as roll goes. So here's the questions....what else can I do to further improve the suspension?

 

Eibach springs
Koni red Shocks/Struts
Energy Suspension polyurethane bushings
Sub fram connectors
and the list goes on and on.

 

Tubular LCAs and panhard bar made a big difference on my WS6 GTA, which already had 36mm/24mm swaybars. Now the rear end is much more predictable and smooth. Corner drifts are about 5 times easier now.

 

Adding a wonderbar is the best bang for the buck suspension mod ever. Do it now. Then get SFC's.

 

forget the wonderbar, it is nice little thing for prevention, and well worth the low price, but not exactly noticable for handling. get a strut tower brace if you want to stiffen the front end up.

 

If you're still running the original shocks/struts, changing them will make a HUGE difference. You could change them to the cheapest strut out there, and you'd probably still feel a difference!
