Hello, new here and just picked up an 06 TL with the factory front Brembo brakes which I hear makes wheel shopping a little more challenging. I am looking at a set of 19x8.5 VMR V710's with a +45mm offset and am wondering if they will clear the brakes and if I could still drop it on coilovers without it rubbing excessively? Has anybody ran these or a set with the same specs? Thanks!

The measurements you provided are insufficient to determine whether the wheels will fit. For cars with the Brembo brakes, you need to know the back spacing as well. Keep this in mind, TireRack lists roughly 200 different wheels which will fit the stock 3G TL; but less than a tenth of that number for cars with Brembo brakes.

For brake clearance...what does backspacing tell you that offset doesnt?
Backspacing is distance from rear rim flange to hub face. Its basically a different expression/translation of offset.
Example...
A 17x8.5 +45 RPF1 has the same backspacing as a 17x8.5 +45 Volk CE28.
One wheel fits bigger brakes.
Any wheel with the same width and offset will have the same backspacing.
Brake fitment comes down to spoke design and wheel face design. Not backspacing or offset.
There are ways where backspacing translation allows you to theorize fitment to the INNER fender. But..again, its just a translation of offset. Think if it as a different spot of reference rather than a different set of data.
Unless I'm missing something....

Offset is a calculation of where the physical rim sits (i.e. how far inside the fender) relative to the wheel to brake hub interface; back spacing is the measure of the gap between the back side of the wheel spokes relative to the wheel to brake hub interface; a very different metric.

Here's a diagram from the link you posted.
Which statement do you feel that the link YOU have provided proves out?
And now...what does backspace tell you about brake fitment that offset doesn't?
I think the biggest difference between offset and backspacing is that one of them would just go, "ah...my mistake, I guess I had it wrong" rather than disappearing like a vapour.
THIS IS GOOD JOKE we are still friends.
But seriously...backspacing isn't going to define brake fitment any more than offset/width would.
Backspacing is derived by using a formula involving width and offset.
So if the width and offsets are variables...x and y ..
If X and Y are the only variables in an equation...and X and Y are equal between two wheels...
then a wheel of the same width and offset will always result in the same answer for backspacing.
At least...that's my uneducated opinion of mathematical formulas.
I've forged forth and expressed/simplified the equation thusly....

The link you posted has the same solid info. Good blokes, them.
Okay, I yield; I have been spouting bad information for years; thanks for calling me on it.
The above said, there is another measurement, for the gap between the mounting surface and the back of the wheel spokes, this is what I have habitually, and incorrectly as it turns out, referred to as "backspacing". What is the name of the third measurement? Not sure yet; I am researching that point.
I guess at this point I need to revive a closing comment from a poster on a different forum I used to communicate with, "I'm often wrong, never uncertain."

You posted this while I was researching and composing my, "ahhh...my mistake" post.
One other item of note, pick a site which sells aftermarket wheels and look for the number of wheels which fit a 3G TL with, and without, Brembo brakes and you come up with typically at least a 10:1 ratio of available wheels; here are the wheel counts for TireRack:
17" Wheels: Non-Brembo: 119 -- Brembo: 09
18" Wheels: Non-Brembo: 321 -- Brembo: 27
19" Wheels: Non-Brembo: 113 -- Brembo: 01
There is clearly another measurement which needs to be obtained to determine if any given wheel will fit a 3G TL with Brembo brakes.

Unfortunately, I don't think any simple measurement for this exists.
You'd need to map the curve of the spoke and find the areas of intersection with the caliper face. #calculus
One wheel may have a bigger hub face and shorter spokes.
One wheel may have straight spokes that make wheel clearance difficult.
Think about an RPF1. Short and straight spokes. Mostly thin/flat lug (front) face so the spokes start close to the hub. No brake clearance as compared to other wheels of the same size/offset.
Now think of any current ADVAN model. Designed specifically for brake clearance. Long, barrelled out spokes. Deeper lug (front) face. Apples to apples, they clear more brakes than most other wheels.
A lot of BBK companies make templates for fitment. I am not entirely sure how TR gets their data. I can assume that the wheel manufacturer needs to meet their selling requirements and either gives them clearance info or gives them CAD to help determine.
Wow, there's some really informative stuff here. It seems like my best bet is to test fit & drive around some before purchasing a set. Might just go for some Type-S waffles after all lol. Thank you all for the replies!
