I was thinking about buying spacers to compliment my lower springs when I get it all together. I just want info for right now for those who have the G knowledge. What are the best spacer size to get for Tein S. Tech springs with 19" wheels 8.5? I'm running these tire sizes:

225/40/19
245/45/19

And plan to stay that size. I'm also going to purchase Ground Force 07's which will be the same specs as my 19" rays, so all of it needs to be right. Yes I searched and got 20mm F and 25mm R, but I want to be sure with the 45's and not 40's all around. I just want a nice flush. If I need to, I will fender roll rear, just NO CAMBER Lol thanks for any help!

 

If you don't want any camber, you'll need to look into camber kits. With a mild drop like the S-techs, you'll only pick up about 1.5 degrees of camber which is livable without camber correction, so that depends on your preference. As for the spacers, that will depend on the offset of the wheels. Most people do use 20-25mm spacers for the OEM Rays. If you are going with the same specs of wheels as the Rays I would recommend sticking to the OEM tire size, the 245/45 in the rear may be too tall in respect to the front which may throw off your ECU/VDC (do a search for the 3% rule).

All in all, 20/25 front/rear should get you around flush. Just be careful with your tire selection and if you want absolutely no camber then get camber kits.

 

By far the best reply in years... I got everything I ended to know in this one post. Thanks!
