Front = 245/35/19
Rear = 275/30/19

He says they will fit with "no rubbing" although he may have to heat up the plastic under the front fender to make sure? I know many have done this and it is really not a big deal.

However, I want to lower the car eventually...Tein or Eibach??? And I am thinking that his setup (tires) would have issues so I am thinking about going with this setup:

Front = 235/35/19
Rear = 265/30/19

This would bascially be the same setup as Joe Z... see https://www.clublexus.com/forums/is-...-f-wheels.html and he seems to not have any problems and this is a daily driver.

So if I go with my setup what would be my issues other than the fact thay this setup would be smaller diameter causing my Revs per mile to increase...and what does that really mean and how does it affect the car...also this setup would be lighter (total weight) as the tries would be lighter that the 245/275 set up...thanks.
