I am on tein s-tech springs with 20/25 H&R spacer combo. Check out the first two posts in my thread (
LMBmikeZ - 40th anniversary) you can see the difference and IMO I think 305's could fit depending on the tire with no rubbing. I also have my alignment results posted to and I got it all back to OEM specs, well all but my front left it is a little out as you will see but not worried, just means I know I should get full SPC camber kit front and rear
