ok so after a few weeks of research ive decided to go with the following setup. please let me know if there are any problems (rubbing, VDC issues, etc) as i'm planning to buy these tomorow morning

18x8.5 +38 with 245/45/18 tires FRONT
18x9.5 +45 with 275/35/18 tires REAR

car is a 03 sedan btw
Thanks

man dont get 18's.. get 19's atleast. go with some 19x8.5 front and 19x9.5 rear

The wheels specs are perfect. In regards to tires, I would either go 245/45/18F & 275/40/18R or 245/40/18F & 275/35/18R.

I really wanted to reduce the fender gap in the front thats why i decided to get 245/45/18F..
For the rear, i read somewhere that 275/40/18 would rub with 18x9.5 +45

Dont fill in fender gap with more rubber... i would get a bigger rim... 18's are ok but 19's are better

i would go +40 in the back, if you are considering stoptech's 14" BBK in the back. i have it (14" stoptech BBK front & rear) and in the back the clearance between the caliper and the wheel is about 1.5mm - this is with +43 offset in the back. if you go a little higher, it won't fit.

now, that's the only consideration - but i'd go with equal offset front and rear on 8.5-wide and 9.5-wide rims. +43 would be perfect, +40 and +45 would also work.

+50 in the front *will* rub on the shocks.

so no VDC issues with the setup i mentioned?

Offsets are good, but I would go with 245/40f and 275/40r. Closest to stock tire height and minimum speedo error.

wa wheels are you plannin to get..jus curious?

I ordered my rims as well and am looking to do
either 245/40/18 and 275/35/18 2.58% difference
or
235/40/18 265/35/18 3.08 difference

Which one should i go with, and will VDC be an issue here??!

Here is the tire size calculator I use.

There are some others out there as well.
