So here's the deal - I got 25mm spacers (H and R) on the back and 20mm on the front yesterday. I absolutely love the front. It's perfect. The back, however, is still not how is like it to be. It just doesn't look as wide as I'd like it to be. I'm running 275/40/22 tyres. In terms of driving - wow - Handles better, more stable, and more planted than before fitting the spacers. It's definitely noticable. Does anyone know if it's okay to have 20mm on the front and 30mm on the back. Will it affect my suspension or bearings? Will my wheels come flying off???
