I'm running -2.0° front and -2.3° in the rear for camber currently without any rubbing going on. I'm going to be dialing it back slightly to -1.5°/-1.8° as I'm doing mostly highway driving this summer. I wasn't a fan of the 6-lug Forgestar offsets as they push out the wheels too close to the fender for my liking.

Ding, ding, ding! Yeah, they are a little tight for me as well with 1 degree all the way around. I was going to step up to 2 degrees and see how it works. Your settings confirmed I need to try this.

ok, well I'm debating if I should modify the stock wheels or just bite the bullet and do a 5 lug conversion. Between buying a spare set of stock wheels, having them widened, then getting them powder coated I'm going to have about $1800-$2000 in a set of stock wheels. If I'm going to spend that kinda of money I prefer to buy a new set of wheels.

So if I were to buy new wheels, what offsets should I be looking for if I was to run a 19x9 in the front and 19X10.5 in the rear.

I'm thinking something along the lines of
19x9 +40
19x10.5 +55

i'll be running a square 19x9.5 +33mm set, but i'll be running a 245/35 all around which is one size shorter than stock. i don't need traction, but i do need clearance.

the forgestars are 19x9 +40mm in front, 19x10 +42mm in rear. the front is about as much inwards as you can go with knuckle and upper control arm clearance. the rears are about as wide as you can go with stock trailing arms and fenders (you may still need a roll). the fronts are honestly conservative to me. mine will poke 13mm more in front and have the same inner clearance and in rear they'll poke 2mm more and have 15mm more inner clearance.

use this calculator to determine what you think you can fit: www.willtheyfit.com

if you want the same outer clearance with a 19x10.5 wheel as the 19x10 forgestar you need an offset of +48mm. inner clearance will be 12mm less than the forgestar which would 100% require the CS wide trailing arms. food for thought.

I can see this if you don't like the looks of the factory wheels, but saying because I have to spend $1800 I should just go and spend another $1800 makes no sense to me.

Bio248

no way it costs anyone $1800 to do the conversion. that's completely off base.

5 lug conversion will cost $250-$300 max. C5 corvette hubs, redrill stock rotors, done.

Bio248

even doing mine "the right way" was only $1200.

I guess there is cheap, and then there is right. Good luck!

I'll throw in my $.02.

For example, my STS-V wheels:
Size 19" x 9.5"
Diameter 19"
Width 9.5"
Offset 56mm
Spacer 13mm (1/2")
Tire Size 275/35/19
Will fit 295/30/19



No trailing arm changes needed.

Bio248

you have me thinking against getting new trailing arms now since i'll be another 10mm less (effective) offset than what you have now. nice.

I would get them regardless just for the beefy greasable spherical balljoint end

Even without the spacer the wheels almost fit. On my car, the passenger side cleared but the drivers side scraped the inner shoulder of the wheel. A 5mm spacer probably would have provided enough clearance out back, a 10mm spacer would work well, and a 1/2" was what came with my car. The front wheels needed the most spacing. I think 10mm is minimum up there, but it has the 13mm all around.

Is that a Z car in the reflection on your car wheels look good by the way

No, that was a 335i.

Can you post more pictures? Some from the side and rear if you don't mind! I am trying to figure out a way to get more tire out back.....

As requested:








This was with the bald 295's that I bought it with:

I am in the exact same scenario as you. I am making 465 rwtq and this will likely be going north to around 500 rwtq so I think the 8.5 inch rims will need to be widened. I like the stock rims. They look good when painted and cleared. Thinking of widening these....

Adding an inch to the backside of those stock wheels should open up a lot of tire size options.
