I think 19x9.5" ET25 - 265/35r19 is the widest I've heard of, directly from Apex wheels.

my research says 255 40 19 will fit the front, 19x9.5 will fit, offset 25mm will fit.

just not sure if there will be any poke with this

I run 19x9 et28 with a 255/40r19 in the front.

I have physically bolted a 275/35r20 on mine with a stock 759 rear (20x9 et44) plus a 17.5mm spacer as well and that fit - even being lowered on Dinan springs.

There’s more room available up there than people give these cars credit for.

First three pics are my 19” setup. The clearance pics are with the 275/35r20

any chance of clearance pics (on the inside of the rim) for the front?

The 20x9 rear with a 17.5mm spacer pictured in clearance photos is really close to an et28, just like the Apex wheels I have on it now (44-17.5=26.5). The Apex wheels technically sit 1.5mm closer than pictured, but still have plenty of clearance. To go wider, you need to increase poke. You can fit a 9.5 wide under the G30 fenders with an et in the +20 range without too much poke. 10 wide really needs the wider F90 fenders to get good coverage and not have too much poke IMHO, unless you can get camber into the -2.0 degree (or more) range via Hardrace upper control arms.

thanks so now i know that with the rears it won't poke by going 19x9.5 ET25 (255 40 19 square), but the front might

but then if i use more offset eg ET30 will it clear the suspension and fender lining in the front
