AZ- so you're running this setup right now (from the other thread)?
"19x9.5 with +41 offset and 19x10.5 with +27 offset. I am running 15mm H&R spacers up front and 20mm in the rear."
So you're at +26 front +7 rear?
instead of lowering it, how about this? swap out the front spacers to 10mm (ET36) and 10mm for rear (ET17). this will make the wheels fit better without lowering. as you probably already know, lowering a car introduces all sorts of other issues so you need to be committed in following through with a lot of misc crappage.
GL with watever you decide!
