RPF1 Dilema
I have the Shine widebody front fenders, however, RPF1 doesn't seem to carry 9.5 x 30 offsets. Does anyone have the Shine fenders with RPF1s with a width of 9 or higher? If so what is your width/offset and is it pretty flush? BTW, 18 rims pls
Advan has the correct setup, but, are so much more expensive, so I thought RPF1 would be a good compromise if I can find the right setup.

Depends on how much front camber you will be running.
Stock is 0 camber.
Maximum -2.5 to -3.5 degrees is available depending on how low the car is.
Each degree of camber moves the top outside edge of the tire 5.5mm.So, offset for "flushness" will vary up to 19mm depending on camber.
The 18x9.5 +30 with 245/35-18 is a good fitment for stock 0 degrees front camber and the Feed front fenders (or knock-offs).
18x10 +38 with 255/35-18 will fit the same on the outside and have plenty of room on the inside.
On the other end of the camber spectrum, Feed runs 18x11 +30 with 295/30-18 at what looks like max available camber (-2.5 at 25" ride height).
18x12 +30 with 315/30-18 would be the max fitment and might require a little work.

Assuming that the shine fenders you are referring to are the feed style ones, you can do the 18x9.5 +30
These RPF1s are 17x10 +38 and there was some more room in the front
These are 18x9.5 + 22 and thats really the max i would go on the fronts with the shine fenders

i dont recall my exact alignment values but i am around -2.5 degree on the front and 275 tires both on the 17x10 and on the 18x9.5
what size tire are you running with the 18x11 ?

What I really like is my FD is Pearl White, same hood and headlights, so I can see how that fitment looks on something 99% exactly like mine. 👍 I just have my hood painted and the vents left carbon.

while the fitment is pretty close on our setups you can probably get more clearance with the rolled/pulled fenders as opposed to the fiberglass feed fenders

Originally I wanted +29 up front +35 in back. That would eliminate the space up front you have. But they only make the 10's in a +38 and 9.5's in a +15 or +38. Crap choices for the front.

So, biting the bullet and figure I'll go 10x18 +38 square on the RPF1, being that that seems to be the closest offset to what I need.
Big question now is, anyone have any insight as to how big of a spacer I'd need up front? I am thinking 10 or 12mm, and a 5mm in rear. Am I way off? Looking for close to 0 camber and working on tire size now.
Any help is appreciated, just ready to get the car on the road before it gets warm. Feels like I've been researching rims forever and getting nowhere due to limited offsets

I wouldn't personally recommend using those spacer kits that come with studs. It's just an additional potential point of failure, and it adds weight.

Appreciate all the input, pulling the trigger on 18x10+38 and spacers.
Next big question is, what is the most comfy tire I can fit that is grippy enough for Mt Driving? Not necessarily the smoothest roads so I need some meat on the wheel for small potholes or occasional rocks, but don't want to rub.

I don't need Cheap, but I don't want to break the bank either.
It's the size I am trying to figure out, I want enough sidewall to handle a pothole or two, and be comfortable when cruising, but performance on tight turns one after the other in my mountains. So no rubber bands, but don't want occasional rub either
And yes, grippy, with occasional water, I'm in San Diego, not much rain other than this year.

Tire choices are a rabbit hole. Go look up testing results, or just slap some PS4S on there and try to avoid burn outs and flat spots

But since you've got 10" wheels, wide fenders, you might as well get 295/30R18s, which are the exact same height as the stock 255/40R17s.
265/35R18s will be only a bit taller, but they will be way lighter and therefore more comfortable (less unsprung mass).
275/35R18s will be quite a bit taller, so your speedo and gear ratios will be off slightly, but more comfortable than 295s because of the extra meat and less weight.
285/30R18s are basically the tires you don't want, since they're smaller, so they have tiny sidewalls.
"Extreme performance" summer tires will be the grippiest, but the loudest, shortest lived, and usually the most expensive.
If comfort and wet grip is an issue, I'd go with something one tier below.

Bro, you're supposed to pick the tire size BEFORE you buy the wheels.

Good for summer and occasional water, not bad for wear or price. The 265 35r 18's are about $250. Shouldn't be a rub issue at this size right?

I think 265s will just about fit in the stock fenders with a bit of persuasion and some camber?
