I want to pick up a set of varrstoen es111. the specs are 18x9.5 +40 and +15. Are the specs too much for a is300?

the 9.5 +40 for the fronts is too high of an offset, will hit suspension and fenders...the 9.5 +15 for the rears are quite low offets, but can be done but with a lot of work (fender rolling/pulling, tire stretching, and negative camber)

those two offsets are like on opposite ends of the spectrum....i would look into some other option

i have 17x9.5 and with a +38 it hit the susp arm, however i placed a 6mm spacer and it barely misses it...

since a 18" wheel is taller and the arm is curved inwards, IM NOT 100% sure but, i think it just might fit.

anyone here has a closer setup than mine up front?

One time I put my 19x9.5 +23 offset rims up front, just to see how it would look.
Hehe, it was impossible to drive, but looked very cool!

it'll work fine with a fender roll and a 225/40 and a little bit of camber w/ +15 offset. The +40 on the other hand will most likely rub your coilover without spacers. dont let these guys scare you

+15 will require more than a fender roll and a little camber. you will need a roll and pull with a good amount of camber (assuming you want to go low)

im running +25 on a 8.5 rim with a roll and a little bit of camber..and with 215/40s
