I just picked up a set of Enkei RPF1 18x7.5 +48 offset. Unfortunately I got the incorrect tire size, but I'm going to attempt to correct that tomorrow. The tires ordered were 215/40-R18, which is a drop in diameter from 25.5" down to 24.8" (-2.7%). It looks like a 215/45-R18 will get it very close with the diameter and the speedometer discrepancy. The wheel well definitely looks too big, but that was also the case with the stock wheels as well. I have a couple of questions.
What spacer size should I go with to make the wheels more flush? Based off some forum posts I can easily go 1" in the rear and 0.5" up front, but the pictures in that thread were no longer working.
What suspension options are available to lower the car a bit? I'm not looking for anything that will make the ride overly aggressive, unless there are no other options. I'm fine with coilovers or a nice strut/spring replacement. The gap in the wheel housing is depressing.
Is there a way to correct the speedometer if I go with a higher profile tire? Reference: viewtopic.php?f=8&t=8026 Not sure how effective this option will be.
