Just curious if anyone knew the offset of the factory A-Spec 18x8.5 wheels for the 3G TL? I am considering a 18x8.5 wheel for my car and was curious what Acura felt was an appropriate offset.
I found one place that said 45et and another that said 42et. Would be nice to know.
Thnak you for any help help you can provide.
(I am not interested in info on the 18x8 version.)

Keep in mind, if your 3G TL has front Brembo brakes, you need one extra measurement, back spacing, in addition to offset to be sure the new wheels will clear your brakes.

thats good feedback. I have the brembo 4 piston front caliper.
i’m considering the Rota Titan 18x8.5 44et (with a 235/40-18 Hankook RS4 that has a unique 8.6” thread width) and am curious if that offset is slightly more or less than the A-Spec 18x8.5. I might consider a “hubcentric-ring integrated” 3mm spacer to achieve an offset closer to the 42et if that is, indeed, the correct offset of the a-spec 18x8.5 option.
Good looking wheel. I just poked around a bit and find it shocking how difficult it is to get any real fitment specs for Rota wheels. This may end up being a case where you'll need to find a retailer with the wheel in stock and do a trial fitment. If you have a 2006 or later TL there may also be the issue of the TPMS sensors and whether they're mountable inside the wheels (probably a pretty good chance they'll fit but better safe than sorry).
Compared to your existing wheel, this new wheel will have an inner rim which is 1mm further away from the suspension strut. The outer rim will poke out 1mm more than before. Seems to make no difference...?

Thank you for making me aware of this website. The biggest concern I have now is clearing the Brembo calipers on the front axle. It seems there is a considerable issues particular to our vehicles due to the shallow rotor “hat” that really amplified the clearance problem. I’ve found a few dealers who seem to guarantee fitment. I’m worried to get “stuck” with a wheel set that will not clear... (prefer no spacers).

In the case of Brembo equipped cars, it isn't so much a shallow rotor hat as it is a very wide caliper.

Backspacing is just the distance from inner lip to mounting surface.
Spoke design plays a big part in brake clearance.
Those Rota Titans in the photo should clear Brembo's without issue.

So in what way are you trying to correct me? If the back spacing is wrong, the spokes of the wheel will not clear the front of the caliper; simple as that.
