Such a simple design and it looks killer! Love the stance and the look. Looks better than your BBS's, imo.

And yeah, a 10.5 with only 255 rubber??

Our shop caters to the whole "stretch" "poke" "tuck" market in our industry... I wanted to make sure the rims ended up into the fenders and I had no rubbing issues.

It's more eye candy than anything. My wife drives it less than 10 miles a day.

I'm using Tein Comfort, lowest setting on the rears, and the fronts have 3 threads left.

These are the first wheels that I have seen that I like better than stock. Maybe it's because I can see what it looks like on the SFP, so less imagination is needed. How much did the ride change? Is it more rough?

Looks good.

I"ve been following this thread and have been hesitant to jump in, but before anyone does this, know this. One should never replace tires on a vehicle with a tire in a lesser load range. As many of you know, I have upsized my tires and kept the stock wheels, but, before I did anything, I made sure the load range was the same or higher. Here, that isn't the case:

Load range (XL tires)

Stock 225/40/19 = 1,433 lbs, Load Range 93Y
OPs 235/30/20 = 1,135 lbs, Load Range 88Y

Stock 255/35/19 = 1,565 lbs, Load Range 96Y
OPs 255/30/20 = 1,389 lbs, Load Range 92Y

That to me is a huge difference, and I'm not even mentioning the OD stagger. Just Food For Thought.

Lou... I never said it was the right setup, and I know fully that its not. Overall diameters are not that far off, but load indexes are... I know fully the risks, but I've been a tire guy for 12+ years and have never seen an issue for "under" loading a tire. That being said, I in no way endorse this type of setup for anybody, and just to remind you this vehicle never sees any type of HWY, and drives 5 mins home, and 5 mins back to the shop at less than 40mph.

We swap over the LM's when the car goes anywhere far...

255-35-19 and 255-30-20 are less than .6% apart. The front was undersized on purpose to achieve a raked look.

Again... Eye Candy The car is setup to look good, thats it !!!
