if you do a decent enough roll, you won't need to stretch any tires and can have a full side profile for maximum comfort and lip protection. A 235/35/19 and 265/30/19 should be good. You could even go up another size if you wanted to for a more comfortable ride.
You MIGHT be able to get away with it. But if you are going to lower your car to any decent looking height, you're going to need to roll it. Just roll the fenders man, it's really not that big of a deal at all and it's really cheap if you pay someone. You could even shave it as to not risk getting any waves or dimples in the fender. But thanks for the compliment, it's a vertex front lip, sides, and rear lip.
i took pics of the GS400 today. trying to find a way for you to look at it. this PM does not let you upload any pics. you have to go directly to my profile garage. i will upload the pics from there. let me know what you think. will try to also upload a short video of the GS400 running so you can hear the exhaust & the engine rumble.
