well since your lowered so much to get back to the stock look you'll probably be good with just doing 15mm all around but i would suggest doing 20/25 if your gonna do the spacers

 

The tone of our exhaust never changes just how loud it gets! With the HFCs and OE exhaust you must have major rasp above 3K rpm. Osiris tunes on the left coast are in the $500 to $600 area, retunes if you upgrade that exhaust are $100=. Good Luck you're going to love the ride after your tune...

What spacers are you running on your car? Your ride looks cleannn

Hmm.. if im going with any exhaust I think I would go with the tdx2.. motordynes legit my favorite company for aftermarket parts for the G
Do you mind telling me what spacers you have for your tires? i want my tires to be like yours lol, your car looks awesome with the kuruma z and impul sides!

 

^in my profile pic no spacers were needed.....specs are very conservative but stretched tires were used to get that look....and i'll tell you my setup is alot more aggressive than what you got now
