changing my offset
 

I have racing sparco NT-R's 17x7 infront with a 45 offset and 17x8 42 offset in the rear..... as u know 42 is a low offset and rubs slightly on bumps So IM hoping maybe a local shop (they gave me some hope) that they can raise my offset a bit.....

my quesation is what offset would be the minum u guys would feel i can run (using a 245 tire) and would this effect anything in a very negitive way example........ is it safe to have a 50 offset rear and a 45 offset front... does that ruin the staggered setup???

sorry as i am not experienced int his area....

How are they going to change the offset of the rim? They are going to shave it? Not a great idea, but it has been done before. No more the 5mm is the recommended last time I heard. But have you just tried to roll your fenders?

If you mean that they are going to get you rims with a +50 offset then yes that will work, the higher the better.

wei have 42 now so is 47 enough????
17x8 not sure...

It's not really enough, but if you roll your fenders and aren't lowered to much you can get away with it. It's better to go higher in the rear.

my front dont need changing..... im trying to not roll ym fenders

From what I can tell the NT-R's do not have a very thick hub surface so I would not suggest shaving that down to gain offset. The best bet is to have somebody do a little work to your fenders, it is a much safer option versus your wheel busting off going down the highway.

how much are they charging you to change the offset? it must be mad expensive. rather just get different rim with the offset you want it.

^50 bucks per wheel

that's pretty cheap for changing the offset. is the work in process ? i really want to see the before and after

They are not changing the offset, they are shaving material off the mounting surface of the wheel which is already made to be lightweight and use as little material as possible to maintain strength. Unless they are willing to warranty that their work will not cause a failure and even then it may not matter because you could possibly be dead as a result I would spend my money on a different set of wheels or have a little bodywork done to the fenders. This is just my opinion but it's your life. I don't think it is worth the risk.
