A 2" spacer is a lot of rake for the LS. My though on cleraance: Swap the front tire with the rear and buy 245/40-19 for the front.

lol 2 inches?

yeah ok. Good luck. This is a massively mickey moused way to go about this. Handling, alignment, and tire wear will be compromised and the car will look straight up silly.

Not really considering that the car is already low. I'll have the alignment redone anyway as well. If someone has a link that will actually help that would be great!

The alignment will be difficult to compensate for the positive camber created by a 2" lift. These same challenges occur going the opposite way where negative camber is pretty excessive. Your tire life will be in the 5-12K mile range and 12K miles may be pretty tough to reach. Performance tires compensate for the slightly negative camber found on performance cars. Those same tires will not have that design compensation for positive camber so tread wear will be unpredictable.

Oh well, I need different tires anyway. I'll let the shop worry about the alignment.

One of our members made a spacer to bolt above the shock/strut mount. The bolts on the mount are usually sufficiently long to add about 1/4". I don't suggest this when there are other easier options like a fender shave or pull.
Which member made that spacer?

He's not active these days. A 1/4" thick spacer is a fairly easy DIY job with some 6061 or 7075 aluminum.

Just run the right size tire. Don't mold your car around tires that are too big. Strut spacers are the wrong way to go. You want to know why? Because NO ONE MAKES THEM FOR THIS CAR.
Run 235 up front 245 rear with 35 profiles as stated earlier and you will not have a rub issue

I don't have the equipment to make them and they need to be more than a 1/4 of an inch.
