Congrats on the GLI. I love mine. The stock GLI has Eibach springs and monroe shocks, so tires are a more pressing issue. I can tell you that I'm UNhappy with my current front tires, which are General Tire Exclaim UHP. Stay far away, they suck when it comes to high speed maneuverability.guidance in parts??? or tires...... Suspension is a def.... always good to have good handleing before your car is insanley fast..... I am getting eibach springs.... and i just have normal struts....
