THis is appropriate for the tire/wheel forums, but wanted to ask specifically to those who have the LS 400. Upgrading to 17 inch wheels, and most tire shops say to use offsett of at least +35mm. The 17 inch wheels I intend to purchase have a widh of 8" and offset of +30mm. Was wondering if this offset would work on the 90 LS 400. Planning to get 235 45 17 tires. Most tire/wheel shops are reading from various books, so I wanted to know first hand from those with actual experience. And yes, bolt pattern as well as center bore match up. Car will not be lowered and has non-adjustable suspension with stock brakes. Thanks in advance for the advice.
