Just got a Is 250 need help with wheels
Given the road conditions, I would suggest for springs, if you're going with RSR, is the Half Downs. It will give you a little drop and still be good for the roads.
The Downs might be much depending on how bad the roads are.
If you want more sidewall, then definitely the 18's would be the way to go, and you can run ones with less offset and a little wider than the stock F Sport rims.
Maybe 18x8.5 front and 18.9.5 rear.
The Downs is the obvious choice, but may not be the practical choice for this scenario.

Not a fan of the tire size choice on a staggered set up, but if you run a 19 with a little more meat on the sidewall you should be fine. EX: 19" wheels w/ 40 sidewall

good modding and good design is all about balance. you don't want any one element to overwhelm the others. And you don't want the design overall to be overwhelming
Since this car is not a super high performance car, the most aggressive I would go are factory F sport.
slamming and dropping on 19" you just end up looking like the other slam bros on the block. So my advice is to go subtle.
You want to massage your car with the mod hammer. Not beat it senseless
I would go half downs, H-tech, Lexus F sport. All Professional mild adult drops. Combined with spacers, you can look professional, subtle, aggressive, capable all in one go. Make sure your car's bite can back up its bark.
