Looking at buying some wheels for my 2015 f type R. I am looking at a set of wheels 20x9 with a 40mm offset and 20x10.5 with a 25mm offset. Wondering will this fit nice and flush. Sorry if this info has been posted somewhere else, but I couldn't find it. Can anyone also tell me what the stock offsets are? Thanks

Terrance-
I believe the stock wheels are 20"x9", +55mm offset front; 20"x10.5", +38mm offset rear
I just installed 21" wheels, same widths, but less offset to get them more flush with the fenders. 21"x9", +32mm offset front; 21"x10.5", +25mm offset rear. These fit perfectly, as the last photo below shows.
Prior to the new wheels I had 17mm spacers on my OEM wheels, effectively reducing the offsets to (55-17=) 38mm front; (38-17=) 21mm offset rear (second photo)
Your specs should work well based on this info.
Thanks for the info that helps alot. It looks like I'm going to be dead on with the rear, but will need an 8mm spacer up front to match your specs. Btw what are you lowered on?

I went with AP Velocity progressive rate springs. They dropped the car 7/8" front and rear, and the ride is not any harsher (from my poorly-calibrated butt)

Upped the tires sizes to 265/30-21" front; 305/25-21" rear. Had to reduce the aspect ratio to maintain the overall diameter of the tires when going up an inch in wheel diameter.
Terrance, the wheels you are looking at are perfect. Will push the front wheel face out 15mm and the rear by 13mm. More than 17mm on the rear will cause rubbing. At 13mm you will still be able to fit a 305 wide tire. Anything more than 17mm on the front, the wheel face position on the front won't match the rear.
Lance,
I on the new wheels I just ordered (9.5 and 11 inch) the offsets are (42mm front and 32 mm rear). Didn't you end up at 43mm front with the 9.5 inch wheel? Aren't you between 18-19mm front offset, with wider wheel considered?

Vince, The 9.5" inch wheels were ordered at 49mm offset (total 12mm extension considering extra wheel width), but the wheel design did not offer sufficient clearance to accommodate the Big Brake option. To get them to fit I added 6mm spacers that I had sitting around (more than enough clearance now). You are correct: that brings total extension to 18mm. Because there is no right angle lip on the front fender, it can accommodate much greater extension than the rear. I have ordered a set of 3mm black anodized spacers as the permanent solution for the front. That color will match the center hub on the Wortecs.
For summary purposes, it then seems that a 21mm front offset is possible? Is this the max, and then what is max on rear? I understand you may want them to be even, but that aside.
Do you know if the CCB rear brakes are bigger that the R brakes? I am hoping for maximum concave on wheels, although the f type picture I posted will still look good imo. I would expect front to be a bit more concave as the CCB's should require more clearance in the front than the R's.

Possible, but not certain. I’ve not tested more than 18mm. CCBs are definitely bigger than the “Big Brakes”. For example, 20” Gyrodynes will not fit over the CCBs.

When you add the 3mm spacers will you not be at 21mm offset or do they not impact the offset?
I wonder if you could help me. I have a 2018 f type r (not ceramic brakes), I recently have Eibach springs put on it, dropping the front .6 and the rear 1 inch. I plan to get vossen 20x9 - 255/35 and 20x10.5 - 295/30 and was suggest the off set be 32 front and 25 rear. Will this cause any driving issues such as rubbing when making turns and such? I see your setup is close to what Im doing so figured I would ask. thanks in advance!
