yeah , already check this chat
i am on the stock suspension
after all the researching, here is my answer

front enkei rpf1 17x8 +45 245x40 17
rear enkei rpf1 17x9 +45 245x40 17

the reason i want keep it +45 off set is this

https://www.wheel-size.com/calc/?whe...cl=30mm&sr=0mm

it will create a positive Scrub Radius in front if i use 17x9 +35

so if i keep 17x9 +45 at front it will against the suspension

finally i put 17x8 +45 , everything is right!
but i dont know is there any BBK issues?
if i am going to put a
BREMBO GT FRONT 4 PISTON SLOTTED OR DRILLED BRAKE KIT





hope someone can help me out !!!

You will have very little room for camber adjustment with offsets that high. And I have no clue if the BBK will clear. Maybe ask the vendor you plan to order from since that is a fairly common wheel I'm sure somebody has tried it.

What are you trying to do with the car that you're so concerned about the scrub radius, but not camber?

You really don't want to mix 9" RPF1's with 8" RPF1's, the spoke shape is different and it's very noticeable. IMO, stick with 17x8's and you're fine.

Also, have you actually checked to see if we have a perfect (0) scrub radius stock? For all you know, moving it slightly positive actually improves the scrub radius. You're also more likely to change the scrub radius adding camber with camber plates than the small change from going to a lower offset wheel.

I like the stock suspension set up
That’s why I soo concerned scrub radius
Don’t want to mass it up
I am assuming that means no change yea should check it
Thx man

Just checked it
The factor is +30mm Scrub Radius
It is same result with 0mm Scrub Radius

You have to determine whether you are doing this for looks or performance. It is questionable whether you'll get any performance increase, but it will probably look good. You can get 90% of any improvement by just changing the tires. I also like the stock setup. Putting on heavier tires/wheels and changing the way the car handles, will affect the stock setup -- especially on the front where most of the handling occurs.

Depending on the way you drive, 245's on the rear would probably not change much. However, I'd probably keep the 215's on the front.

Profermance is the key!
Yea just the tire is way easy!
Best setup for now is 17x8+45 with 245 40 17 tires square

Some people say 245 is to wide for 8
235 is the best for 8 inch
245 will fit the 8 tho

That's the point. Wider tires will not give you better performance. But if you are determined to do it for looks, then that's another matter. Unless you race, of course.... Tire selection makes a huge difference -- much more than wheel width.

jayliu: find brake fitment template for your brakes, print it out, cut, and put at your wheels to test clearance.

[Mr.ac]

Scrub radius? Wow you are again way overthinking this.
Like rovll what are your goals for this car? If you want to some day upgrade to a bbk look up info on the bbk you want, most companies will list what size wheel will clear. Then just go off that.

[churchx]

Brake fitment templates also can be mailed to wheel shop with request to check fitment prior purchase, if you haven't bought wheels yet.
