im chaning out my 17's on my tc and wanted to know with a 17x7 rim should i go with a +40 or +48 offset i want it to look as flush as possible and not sure how offsets work

Youll want to go with the lower number offset to push the wheels further out. Im looking at a 17x8 in a +35 offset for my car to ensure clearance for my big brake kit.

A good way to look at is that the +40 offset will stick out 8mm further than the +48mm offset.

i have 17x8 +32 and its pretty flush all around. well it would be flushed whenever i decide to get an damn alignment.

that is around 18mm-23mm wider than stock. the length that stick outs depends on the tire size you get. if you went with 235/40 with my set up, it would stick out 23mm. if you went with 225/45, it would stick out 18mm. imho the right length to get it flush is around 20-21mm difference from stock.

stock is 17x7 +45 so in order to get it flush with 17x7 wheels, you need to get it a +25 or +24 offset with those wheels.

its generrally harder to get those offsets on a small width wheel such as 7" so you'll have to look in the 17x8 and 17x8.5 variety.

also if ur still confused. try using this calculator

hope i helped out

I used to run 18x8 with a 32mm offset which ran fine

I run a 18x8.5 with a 35 just perfect

neither one of u guys except for the first person to respond accually read my questsion, I said with a 17x7 wheel which offset will look the most flush the 40 or the 48 thats all i asked and since the 40 will pull i t out more thats what i need.

Sorry... 40 will put you closer but still will not be flush.

^^ yup, you should get atleast +35. i currently have 18x7.5 +35 with 225/40. looks really good with my drop. :D

this is an awesome post.. That link up there is very helpful!

Can anyone of you guys post pics so we can see how different offsets line up?

Thanks alot for the good info!
