18x8.5 And 18x9.5 Both W/ 45mm Offset

[jskim9]

I have a set of 18x8.5 @ 45mm up front and 18x9.5 @ 45mm rear rims. Just a general question for those with IS experiences and knowledge.

1. How feasible is it to have on an IS300 that's lowered about an inch all around with that rim combo?

2. What size tire would I need? What's the largest/widest tires that I could have with this combo?

3. What's your recommendation for springs/shock combo or C/O? Preference on streetability

4. Would I have to or is it better to roll my fender?

Thanks in advance
