I recently put some Iforged Flux rims on my G35 Coupe. Fronts are 18 inch with an 8 inch width and an offset of 18mm. Rears are 18 inch with a 10 inch width and an offset of 30 mm. I noticed that the outer edge of the rear tires was not making contact with the ground ( negative camber ). The front tires displayed this characteristic as well but to a lesser extent. The stock rims were the 18 inchers and the suspension is stock. Has anyone with upgraded wider wheels noticed this on your Z or G35 Coupe? Does putting wider wheels on your car effect camber? Is a wheel alignment necessary when replacing wheels? I will be installing Hotchkis Swaybars shortly. Will an alignment be necessary with upgraded swaybars? Thanks in advance for your input...
