Default 19x8 +35 or 19x9 +30 Front Wheels?

Hey all, as the thread title mentions, I'm on the fence over which offset and widths I should go with for a front pair of TSW wheels.
I've searched but haven't found much (if anyone) running 19x9 +30 up front.

I'm sure the 19x8 +35 will fit with no problem going with 235/35/19 tires. My only concern would be if this would not be aggressive enough?
(Might need to add a 5mm spacer perhaps?)

The other option would be 19x9 +30 up front. This width and offset seems like it might be just a bit too aggressive. Would a 225/35/19 tire make it not rub?
But then that might mean the tires will be pretty stretched, which I'm not a big fan of.

This will be paired with a 19x9.5 +39 rear running 265/30/19.

Given the 2 options which one would you guys go with?
Any opinions and suggestions would be awesome!

Wish those specs were available, but the only 19x8.5 is in +15 offset which will definitely probably not fit lol.
Same goes for the rears, which will be 19x10.5 + 27

it will rub if you dont have camber arms.
as for fronts, i have 9.5 +31 but they didnt clear my brakes so i have to run 10mm spacers.

I was in the same boat as you a couple of weeks ago before I decided to go with a different setup. I was going to go with 19x9 et30 with 235/35 tires on the front. I was looking at the Bathurst model. From my research, there are people that run slightly more aggressive setups on here.

The closest I saw was people running 19" Velven wheels. The fronts are 19x9 et35. Think about what 5mm is, that should be pretty negligible.








Another member on here runs 19x10 et35 which is more aggressive than 19x9 et30. Go to page #133 of the "Pics of your 3IS now". Scroll down to the white one with Rotiform wheels.

Good luck! Report back if you go that route! Also, make sure the wheels are in stock or at least in production as it may be a while before those before become available.

Nice thanks for that info. Does the front rubs with those crazy offsets? With 10mm spacers that should put you at +21 Also stock F-Sport brakes you mean or a different BBK?

Thanks for that info as well, much appreciated. The Bathursts were my first choice also haha, but yeah stocking for those are pretty backed up now. Might go with the 19x9 +30 at this rate.

Fsport brakes. im on air so i dont know how far down the rsr's go, but i drive with about a 1 in wheel gap up front. and it only rubs when i hit a big bump. thinking about running 10 up front and 11 in the rear on my next set of wheels.

I run 8,5 +27 fronts with 235/35 rubber - looks like a perfect setup to my taste. 9 +30 is 3 mm wider, should look great but some rubbing issues can appear.
